Description

Adhesive sheet laminate, shaped adhesive sheet laminate, and method for producing the same

The present invention relates to an image forming device such as a personal computer, a mobile terminal (PDA (personal digital assistant)), a game console, a television (TV), a car navigation system, a touch panel, a tablet, and the like. A shaped pressure-sensitive adhesive sheet layered product that can be suitably used in a display device, and an pressure-sensitive adhesive sheet layered product suitable for forming a shaped pressure-sensitive adhesive sheet layered product.

The image display device of the touch panel method is usually composed of a combination of a surface protection panel, a touch panel, and an image display panel (also collectively referred to as "components for an image display device"). In recent years, the surface protection panels of touch panel image display devices such as smart phones and tablet terminals use reinforced glass and plastic materials such as acrylic resin sheets or polycarbonate sheets. The visible opening of the surface protection panel The peripheral part other than the face is printed in black. In addition, in the touch panel, a plastic film sensor is used together with a glass sensor, or a component called single-chip touch (TOL) is used that integrates the touch panel function and the surface protection panel. , or use a surface-mounted or embedded component that integrates the touch panel function into the image display panel. In this type of image display device, in order to further improve the visibility of the image, the gaps between the constituent members of the image display device are usually filled with a transparent resin such as a liquid adhesive, a thermoplastic adhesive sheet, and an adhesive sheet. the structure. In addition, in the field of image display devices centered on mobile phones and mobile terminals, in addition to thinning and high-precision, the diversification of designs has been continuously developed. Previously, the peripheral portion of the surface protection panel was usually printed in black in a frame shape. However, with the diversification of designs, the frame-shaped concealment has been formed in colors other than black. When the concealed portion is formed in a color other than black, since concealability is low, the height of the concealed portion, that is, the printed portion tends to be higher than that of black. Therefore, it is required to fill the corners of the adhesive sheet for laminating the constituent member having such a printed portion, following a large printing level difference. Therefore, various methods for filling the printing step difference have been proposed. For example, in Patent Document 1, there is a new double-sided image display device that can be adhered to the adherend surface in an adhesive state without a gap, even if the adherend surface to which the adhesive sheet is adhered has a level difference due to printing or the like. An adhesive sheet is disclosed, which discloses a double-sided adhesive sheet for an image display device, which is used for combining any two of the constituent members for an image display device selected from a surface protection panel, a touch panel and an image display panel. The double-sided adhesive sheet to be adhered by the adherend, and at least one of the adherends has a step portion on the adhered surface to which the double-sided adhesive sheet is to be adhered. The shape of the joint surface is formed along the shape of the above-mentioned surface to be adhered. In addition, Patent Document 2 discloses a method for producing a double-sided adhesive sheet for laminating any two adherends selected from a surface protection panel, a touch panel, and an image display panel. A method for producing a double-sided adhesive sheet for display devices, characterized in that: the double-sided adhesive sheet before lamination uses an adhesive composition with a gel fraction of less than 40%, and is shaped to be the same as the above-mentioned adherend. The concave and convex shape of the bonding surface is the same surface shape. Prior Art Document Patent Document Patent Document 1: WO2014/073316 A1 Patent Document 2: WO2015/174392 A1

[Problems to be Solved by the Invention] In recent years, in the field of image display devices centered on mobile phones and mobile terminals, further thinning and high precision are required. The adhesive sheet is also required to be able to accurately fill in the unevenness of the surface of the adherend, such as a printing step, and to prevent the adhesive from being exposed to the outside. As a countermeasure against this requirement, as disclosed in the above-mentioned prior patent documents, it has been considered that the surface shape of the adhesive sheet and the surface shape of the adherend are formed in advance. In addition, in order to make the surface shape of the adhesive sheet match the surface shape of the adherend in advance as described above, the following method is assumed. The body is press-molded to form a concave-convex shape conforming to the concave-convex portion on the surface of the adhered body. However, an attempt was made to use an adhesive sheet laminate in which a conventional release sheet was laminated on both sides of an adhesive sheet, and the above method was actually implemented. As a result, the following problem was found: it is difficult to form and adhere to the surface of the adhesive sheet with high precision. The concavo-convex shape conforming to the concavo-convex part on the body surface. Therefore, the present invention proposes an adhesive sheet laminate having an adhesive material layer and a covering portion that is releasably laminated on one side of the adhesive material layer, and proposes an adhesive sheet layer that can be formed on the surface of the adhesive material layer with high precision A new adhesive sheet laminate having a concavo-convex shape conforming to the concavo-convex portion on the surface of an adherend, and a shaped adhesive sheet laminate using the adhesive sheet laminate. [Technical Means for Solving the Problems] The present invention proposes an adhesive sheet laminate comprising an adhesive layer and a covering portion I formed by releasably laminated on one side of the adhesive layer. It is characterized in that: the storage elastic modulus E'(MA) of the covering part I at 100°C is 1.0×10 ⁶ to 2.0×10 ⁹ Pa, and the storage elastic modulus of the covering part I at 30°C E' (MB) is 5.0×10 ⁷ to 1.0×10 ¹⁰ Pa. Further, as a shaped adhesive sheet laminate using the above-described adhesive sheet laminate, the present invention proposes a shaped adhesive sheet laminate, wherein the adhesive layer has a concave portion, a convex portion or Concavo-convex part (referred to as "adhesive layer surface concavo-convex part"), and the coating part I is in close contact with one of the side surfaces of the front and back sides of the above-mentioned adhesive material layer, and has a concave part, a convex part or a concave-convex part on one of the front and back side surfaces part (referred to as "surface concavo-convex part of the coating part"), and the other side surfaces of the front and back sides opposite to the one side of the above-mentioned front and back are provided with concavities and convexities corresponding to the above-mentioned surface concavo-convex of the adhesive layer. A convex part, a concave part or a convex and concave part (referred to as "the back surface convex and concave part of the covering part"). [Effect of the Invention] According to the adhesive sheet laminate proposed by the present invention, for example, after heating the above-mentioned adhesive sheet laminate, a mold can be pressed against the covering portion 1 for molding, so that the surface of the adhesive layer can be formed at a high level. The concave-convex shape conforming to the concave-convex portion on the surface of the adherend is precisely formed. In addition, since the covering portion I can maintain shape retention in a normal state, it is easy to handle, and not only that, because it is not too hard, it is possible to suppress the formation of unintended irregularities in the adhesive layer. The shaped adhesive sheet laminate proposed by the present invention is provided with an adhesive sheet surface concavo-convex portion on one of the front and back side surfaces of the adhesive material layer, and the coating portion I is in close contact with one of the front and back sides of the adhesive material layer. The front surface is provided with a covering portion surface concavo-convex portion on one side surface of the front surface and the back surface, and has a covering portion back surface convex and concave portion on the other side surfaces of the front and rear surfaces on the opposite side to the one side of the front and rear surfaces. As described above, the layered body of shaped adhesive sheets proposed by the present invention is provided with the above-mentioned covering portion I, which is closely adhered to one of the side surfaces of the front and rear surfaces of the above-mentioned adhesive material layer without gaps, and the above-mentioned covering portion I is peelable. The structure formed by laminating the front and back surfaces of the above-mentioned adhesive material layer can prevent dust and the like from adhering to the surface of the adhesive material layer and reduce the adhesive force, and can also prevent the formation of the front surface of the above-mentioned adhesive material layer. The shape of the concave-convex portion on the surface of the adhesive material layer formed on the side surface of the back side absorbs the moisture in the air and disintegrates, or the dust adheres to the surface and the adhesive force is reduced.

根據表1及圖4之結果以及至此為止之試驗結果，確認到如實施例1-1至實施例1-3所示，藉由將於30℃下之儲存彈性模數E'(MB)為5.0×10⁷ ～1.0×10¹⁰ Pa且於100℃下之儲存彈性模數E'(MA)為1.0×10⁶ ～2.0×10⁹ Pa之被覆部積層於黏著材層進行成形，而可對黏著材層高精度地賦形凹凸形狀。 另一方面，如比較例1-1所示，於使用通常廣泛使用之雙軸延伸均聚PET膜作為離型膜之情形時，即使於高溫範圍內被覆部之儲存彈性模數亦超過2.0×10⁹ Pa，故而即使進行熱成形亦無法對黏著材層賦形充分之凹凸。 由此得知，藉由將於30℃下之儲存彈性模數E'(MB)為5.0×10⁷ ～1.0×10¹⁰ Pa且於100℃下之儲存彈性模數E'(MA)為1.0×10⁶ ～2.0×10⁹ Pa之被覆部積層於黏著材層進行成形，而可良好地獲得賦形有凹凸之賦形黏著片材。 亦得知：藉由使用進而較佳為滿足黏著材層於100℃下之損耗正切tanδ(A)為1.0以上之條件且滿足黏著材層於30℃下之損耗正切tanδ(B)未達1.0之條件之黏著片材積層體，而可達成更高精度之賦形。 因此確認，藉由使用如上述之黏著片材積層體，精度良好地賦形相當於成為被黏著體之圖像顯示裝置之印刷階差的凹凸，而可製造與被黏著體之間無間隙、且即使於如印刷部為窄邊緣設計之被黏著體中黏著材亦可不溢出而良好地密接貼合之圖像顯示裝置用賦形黏著片材積層體。 又，就剝離力而言，測定剝離力F(D)時之加熱冷卻條件、即於100℃下加熱5分鐘後使其自然冷卻至30℃之條件係製造賦形黏著片材積層體時之典型之加熱冷卻條件。由於上述實施例中剝離力F(C)與剝離力F(D)之差之絕對值均為0.1 N/cm以下，故而確認賦形黏著片材積層體中之被覆部1-A～1-D之剝離力與黏著片材積層體中之被覆部1-A～1-D之剝離力相同。 [實施例、比較例之群2] ＜被覆部2-I＞

根據表2及圖4之結果以及至此為止之試驗結果，確認到如實施例2-1至實施例2-4所示，藉由以成形開始時之被覆部2-I之儲存彈性模數E'(MS)為1.0×10⁶ ～2.0×10⁹ Pa，且成形結束時之被覆部2-I之儲存彈性模數E'(MF)成為5.0×10⁷ ～1.0×10¹⁰ Pa之方式調整並進行成形，可對黏著材層高精度地賦形凹凸形狀。 另一方面，如比較例2-1所示，於成形開始時之被覆部2-I之儲存彈性模數E'(MS)大於2.0×10⁹ Pa之情形時，即使進行熱成形亦無法對黏著材層賦形充分之凹凸。 由此得知，藉由以成形開始時之被覆部2-I之儲存彈性模數E'(MS)為1.0×10⁶ ～2.0×10⁹ Pa且成形結束時之被覆部2-I之儲存彈性模數E'(MF)成為5.0×10⁷ ～1.0×10¹⁰ Pa之方式調整並進行成形，而可良好地獲得賦形有凹凸之賦形黏著片材。 亦得知：藉由以進而較佳為滿足成形開始時之黏著材層之損耗正切tanδ(SS)為1.0以上之條件且滿足成形結束時之黏著材層之損耗正切tanδ(SF)未達1.0之條件之方式調整並進行成形，而可達成更高精度之賦形。 因此確認，藉由使用如上述之黏著片材積層體，精度良好地賦形相當於成為被黏著體之圖像顯示裝置之印刷階差的凹凸，而可製造與被黏著體之間無間隙、且即使於如印刷部為窄邊緣設計之被黏著體中黏著材亦可不溢出而良好地密接貼合之圖像顯示裝置用賦形黏著片材積層體。 又，就剝離力而言，測定剝離力F(D)時之加熱冷卻條件、即於100℃下加熱5分鐘後使其自然冷卻至30℃之條件係製造賦形黏著片材積層體時之典型之加熱冷卻條件。由於上述實施例中剝離力F(C)與剝離力F(D)之差之絕對值均為0.1 N/cm以下，因此確認剝離力於加熱前後幾乎無變化。 進而得知，藉由加熱黏著片材積層體，於被覆部2-I之儲存彈性模數E'(MS)為1.0×10⁶ ～2.0×10⁹ Pa之狀態下開始成形，於被覆部2-I之儲存彈性模數E'(MF)為5.0×10⁷ ～1.0×10¹⁰ Pa之狀態下結束成形，而可於黏著材層表面高精度地形成與被黏著體表面之凹凸部相符之凹凸形狀。 [實施例、比較例之群3] ＜被覆部3-I＞ 作為實施例3-1～3-3及比較例3-1～3-2(以下亦統稱為「實施例、比較例之群3」)中之黏著片材積層體之被覆部3-I，使用於雙軸延伸間苯二甲酸共聚合PET膜(厚度：75 μm)之單面積層包含聚矽氧系化合物之離型層(厚度：2 μm)而成之膜。將各自之儲存彈性模數之值示於表3。 ＜實施例3-1＞ (雙面黏著片材之製作) 將作為(甲基)丙烯酸系共聚物(3-a)之數量平均分子量2400之聚甲基丙烯酸甲酯巨單體(Tg：105℃)15質量份(18 mol%)、丙烯酸丁酯(Tg：-55℃)81質量份(75 mol%)及丙烯酸(Tg：106℃)4質量份(7 mol%)無規共聚合而成之丙烯酸系共聚物(3-a-1)(重量平均分子量23萬)1 kg、作為交聯劑(3-b)之甘油二甲基丙烯酸酯(日油公司製造，製品名：GMR)(3-b-1)90 g、及作為光聚合起始劑(3-c)之2,4,6-三甲基二苯甲酮與4-甲基二苯甲酮之混合物(Lanberti公司製造，製品名：Esacure TZT)(3-c-1)15 g均勻地混合，而製作黏著材層所使用之樹脂組合物3-1。所獲得之樹脂組合物之玻璃轉移溫度為-5℃。 利用經離型處理之PET膜(三菱樹脂公司製造，製品名：Diafoil MRV-V06，厚度：100 μm)與被覆部3-I之2片將所獲得之樹脂組合物3-1夾持，使用貼合機以樹脂組合物3-1之厚度成為100 μm之方式賦形為片材狀，而製作黏著片材積層體3-1。再者，以與樹脂組合物3-1相接之方式配置被覆部3-I之離型層側。 所獲得之黏著片材積層體3-1係使用真空壓空成形機(第一實業公司製造，FKS-0632-20形)及成形用模具，藉由以下之製程進行熱成形，而製作賦形黏著片材積層體3-1。 關於成形用之模具，如圖5所示，上下一模具為長度270 mm、寬度170 mm、厚度40 mm之凸模具，上下另一模具為長度270 mm、寬度170 mm、厚度40 mm之鋁平板。對於上述凸模具之成形面，如圖5所示，於中央設置縱187 mm、橫125 mm、高1 mm之凸部，進而，於該凸部之成形面內設置深度為25 μm、50 μm、75 μm、100 μm之4個俯視長方形狀(縱89 mm、橫58 mm)之成形凹部。 藉由預熱為400℃之IR加熱器，加熱至黏著片材積層體3-1之被覆部3-I之表面達到100℃，使用將模具表面溫度冷卻為30℃之成形用模具，將該加熱狀態之黏著片材積層體3-1於鎖模壓8 MPa之條件下進行5秒之加壓成形後打開模具，而製作對表面賦形凹凸而成之賦形黏著片材積層體3-1。 ＜實施例3-2＞ 使用預熱為400℃之IR加熱器，將實施例3-1中所使用之黏著片材積層體3-1加熱至黏著片材積層體3-2之被覆部3-I之表面達到70℃，使用將模具表面溫度冷卻為30℃之成形用模具，將該加熱狀態之黏著片材積層體3-1於鎖模壓8 MPa之條件下進行5秒之加壓成形後打開模具，而製作對表面賦形凹凸而成之賦形黏著片材積層體3-2。 ＜實施例3-3＞ 使用預熱為400℃之IR加熱器，將實施例3-1中所使用之黏著片材積層體3-1加熱至黏著片材積層體3-3之被覆部3-I之表面達到100℃，使用將模具表面溫度調整為50℃之成形用模具，將該加熱狀態之黏著片材積層體3-1於鎖模壓8 MPa之條件下進行5秒之加壓成形後打開模具，而製作對表面賦形凹凸而成之賦形黏著片材積層體3-3。 ＜比較例3-1＞ 使用預熱為400℃之IR加熱器，將實施例3-1中所使用之黏著片材積層體3-1加熱至黏著片材積層體3-5之被覆部3-I之表面達到60℃，使用將模具表面溫度冷卻為30℃之成形用模具，將該加熱狀態之黏著片材積層體3-1於鎖模壓8 MPa之條件下進行5秒之加壓成形後打開模具，而製作對表面賦形凹凸而成之賦形黏著片材積層體3-4。 ＜比較例3-2＞ 使用預熱為400℃之IR加熱器，將實施例3-1中所使用之黏著片材積層體3-1加熱至黏著片材積層體3-5之被覆部3-I之表面達到100℃，使用將模具表面溫度調整為80℃之成形用模具，將該加熱狀態之黏著片材積層體3-1於鎖模壓8 MPa之條件下進行5秒之加壓成形後打開模具，而製作對表面賦形凹凸而成之賦形黏著片材積層體3-5。 ＜測定及評價方法＞ 對實施例3-1～3-3及比較例3-1～3-2中獲得之樣品之各種物性值之測定方法及評價方法進行說明。 (被覆部之彈性模數) 被覆部3-I之儲存彈性模數係切成長度50 mm、寬度4 mm，使用動態黏彈性裝置(IT Meter and Control股份有限公司之DVA-200)，以夾頭間距為25 mm並且施加1%之形變而進行測定。於測定溫度範圍為-50℃～150℃、頻率為1 Hz、升溫速度為3℃/min之條件下進行測定。 於所獲得之資料中，將30℃下之被覆部3-I之儲存彈性模數之值設為E'(MB)，將100℃下之被覆部3-I之儲存彈性模數之值設為E'(MA)。 (黏著材層之彈性模數) 將實施例、比較例之群3中獲得之黏著材層重疊而積層為1 mm之厚度，使用流變儀(Thermo Fisher Scientific公司製造之MARSII)進行測定。於測定溫度範圍為-50℃～150℃、頻率為1 Hz、升溫速度為3℃/min之條件下進行測定。 於所獲得之資料中，將100℃下之儲存彈性模數之值設為G'(SA)，將損耗彈性模數之值設為G''(SA)，將30℃下之儲存彈性模數之值設為G'(SB)，將損耗彈性模數之值設為G''(SB)，將各溫度條件下之G''/G'之值設為各黏著材層之損耗正切tanδ(SA，SB)。 (成形性) 將實施例、比較例之群3中獲得之賦形有凹凸之賦形黏著片材積層體之被覆部I剝離，分別使用掃描式白色干涉顯微鏡，以非接觸方式計測相當於印刷階差之凹部與相當於顯示器面之凸部之高度。 計測成形體之凸部(與凹部之邊界部)相對於模具之深度100 μm之高度h，將由下述計算式導出之轉印率為50%以上者評價為「○」，將未達50%者評價為「×」。 轉印率(%)＝h(成形體高度)/100(模具深度)×100 (翹曲、彎曲) 將實施例、比較例之群3之各成形條件下所製作之黏著片材積層體切成長度100 mm之正方形，計測各頂點之高度。將所獲得之4點之高度進行平均而以該值作為翹曲。將翹曲之高度未達10 mm者判定為「○」，將為10 mm以上者判定為「×」。 (剝離力) 將實施例、比較例之群3中所製作之黏著片材積層體切成長度150 mm、寬度50 mm，對被覆部3-I與黏著材層之界面以試驗速度300 mm/min進行180°剝離試驗。 將30℃環境下之剝離力設為F(C)，將於100℃下加熱5分鐘後使其自然冷卻至30℃後之剝離力設為F(D)，以所獲得之值分別作為被覆部3-I之剝離力。 將實施例3-1～3-3及比較例3-1～3-2中獲得之賦形黏著片材積層體3-1～3-5之評價結果示於表3。 [表3]

根據表3之結果以及至此為止之試驗結果，確認到如實施例3-1至實施例3-3所示，藉由以於被覆部3-I之表面溫度為70～180℃之狀態下開始成形，於被覆部3-I之表面溫度成為未達60℃後結束成形，並從模具取出成形品之方式進行成形，而可對黏著材層高精度地賦形凹凸形狀。 另一方面，如比較例3-1所示，若成形開始時之被覆部3-I之溫度未達70℃，則即使進行熱成形亦無法對黏著材層賦形充分之凹凸。 又，得知如比較例3-2所示，若於結束成形並從模具取出成形品時被覆部3-I之表面溫度為70℃以上，則伴隨片材之熱收縮，成形品會產生翹曲或彎曲而欠佳。 由此得知，為了更高精度地進行凹凸賦形，較佳為以於被覆部3-I之表面溫度為70～180℃之狀態下開始成形，於被覆部3-I之表面溫度成為未達60℃後結束成形，並從模具取出成形品之方式進行成形。 因此確認，藉由使用如上述之黏著片材積層體，精度良好地賦形相當於成為被黏著體之圖像顯示裝置之印刷階差的凹凸，而可製造與被黏著體之間無間隙、且即使於如印刷部為窄邊緣設計之被黏著體中黏著材亦可不溢出而良好地密接貼合之圖像顯示裝置用賦形黏著片材積層體。 又，就剝離力而言，測定剝離力F(D)時之加熱冷卻條件、即於100℃下加熱5分鐘後使其自然冷卻至30℃之條件係製造賦形黏著片材積層體時之典型之加熱冷卻條件。由於上述實施例中剝離力F(C)與剝離力F(D)之差之絕對值均為0.1 N/cm以下，因此確認剝離力於加熱前後幾乎無變化。 [實施例之群4] 以下之實施例4-1～4-5(以下亦統稱為「實施例之群4」)中所使用之聚酯原料之製造方法如下所述。 (聚酯4-A之製造方法) 取對苯二甲酸二甲酯100份、乙二醇70份、及乙酸鈣一水合物0.07份置於反應器中，進行加熱升溫並且將甲醇蒸餾去除而進行酯交換反應，反應開始後，需要約4個半小時升溫為230℃，而實質性地結束酯交換反應。 繼而，添加磷酸0.04份及三氧化銻0.035份，按照常規方法進行聚合。即，緩緩提高反應溫度，最終設為280℃，另一方面，緩緩降低壓力，最終設為0.05 mmHg。4小時後，結束反應，按照常規方法進行碎片化而獲得聚酯4-A。所獲得之聚酯碎片之極限黏度IV為0.70 dl/g。 (聚酯4-B之製造方法) 於上述聚酯4-A之製造方法中，作為二羧酸單元，將對苯二甲酸設為78 mol%，將間苯二甲酸設為22 mol%，除此以外，藉由與聚酯A相同之方法進行製造而獲得聚酯4-B。所獲得之聚酯碎片之極限黏度IV為0.70 dl/g。 (聚酯4-C之製造方法) 於製造上述聚酯4-A時，添加平均粒徑3 μm之非晶質二氧化矽6000 ppm，而製作聚酯4-C。 (聚酯4-D之製造方法) 於製造上述聚酯4-A時，添加平均粒徑4 μm之非晶質二氧化矽6000 ppm，而製作聚酯4-D。 [實施例4-1] 藉由熔融擠出機將分別以65重量%、30重量%、5重量%之比例混合上述聚酯4-B、4-A、及4-D而成之原料熔融擠出，而獲得單層之無定形片材。 繼而，將片材共擠出至經冷卻之流延鼓上，使其冷卻固化而獲得無配向片材。繼而，於80℃下沿機械方向(縱向)延伸3.4倍後，進一步於拉輻機內經過預熱步驟，而於80℃下沿與機械方向垂直之方向(橫向)延伸3.9倍。進行雙軸延伸後，於185℃下進行3秒之熱處理，其後沿寬度方向進行6.4%之鬆弛處理，而獲得厚度50 μm之聚酯膜。將評價結果示於下述表4。 [實施例4-2]、[實施例4-3] 除了變更為下述表4所示之條件以外，以與實施例4-1相同之方式獲得聚酯膜。將評價結果示於下述表4。 [實施例4-4] 以將上述聚酯4-A及4-C分別以86重量%、14重量%之比例混合而成之原料作為表層用之原料，以將聚酯4-B及4-A分別以45重量%、55重量%之比例混合而成之原料作為中間層用之原料。分別藉由不同之熔融擠出機熔融擠出，而獲得2種3層積層(表層/中間層/表層)之無定形片材。 繼而，藉由將片材共擠出至經冷卻之流延鼓上，並使其冷卻固化，而獲得無配向片材。繼而，於82℃下沿機械方向(MD)延伸3.4倍後，進一步於拉輻機內經過預熱步驟，而於110℃下沿與機械方向垂直之方向(寬度方向，TD)延伸3.9倍。進行雙軸延伸後，於210℃下進行3秒之熱處理，其後沿寬度方向進行2.4%之鬆弛處理，而獲得厚度50 μm之聚酯膜。將評價結果示於下述表4。 [實施例4-5] 除了變更為下述表4所示之條件以外，以與實施例4-4相同之方式獲得聚酯膜。將評價結果示於下述表4。 ＜測定及評價方法＞ 對實施例之群4中獲得之樣品之各種物性值之測定方法及評價方法進行說明。 (1)儲存彈性模數(E') 關於實施例之群4中獲得之膜，以長度方向成為機械方向之方式採集長度方向30 mm×寬度方向5 mm之樣品。繼而，使用動態黏彈性裝置(IT Meter and Control公司製造之「DVA-220」)，將樣品夾持於將間隔設置為20 mm之夾頭而加以固定後，以升溫速度10℃/min從常溫升溫至200℃，於頻率10 Hz下測定儲存彈性模數。根據所獲得之資料，讀取100℃下之儲存彈性模數。 (2)加熱收縮率 從實施例之群4中獲得之膜之寬度方向中央位置起，以樣品長度方向成為測定方向之方式將樣品切成短條狀(15 mm寬×150 mm長)，於無張力狀態、120℃環境下熱處理5分鐘，測定熱處理前後之樣品之長度，藉由下述式計算膜之熱收縮率(%)。再者，下述式中之a為熱處理前之樣品長度，b為熱處理後之樣品長度。 加熱收縮率(%)＝[(a－b)/a]×100 (3)加熱處理後之膜表面低聚物量 對於實施例之群4中獲得之膜，於氮氣環境下藉由180℃之熱風循環烘箱將聚酯膜處理10分鐘。使熱處理後之聚酯膜之表面與DMF(二甲基甲醯胺)接觸3分鐘，使析出至表面之低聚物溶解。該操作可採用於例如關於聚烯烴等合成樹脂製食品容器包裝等之自願性基準中，於溶出試驗中之單面溶出法所使用之溶出用器具中所記載之方法。 繼而，視需要藉由稀釋等方法調整所獲得之DMF之濃度，供給於液相層析儀(島津LC-2010)而求出DMF中之低聚物量，該值除以接觸DMF之膜面積，作為膜表面低聚物量(mg/cm² )。 DMF中之低聚物量係根據標準試樣峰面積與測定試樣峰面積之峰面積比求出(絕對校準曲線法)。 標準試樣之製作係準確地稱量預先分取之低聚物(環狀三聚物)，溶解於經準確地稱量之DMF中而製作。標準試樣之濃度較佳為0.001～0.01 mg/ml之範圍。 (4)成型加工適性 將作為(甲基)丙烯酸系共聚物之數量平均分子量2400之聚甲基丙烯酸甲酯巨單體(Tg：105℃)15質量份(18 mol%)、丙烯酸丁酯(Tg：-55℃)81質量份(75 mol%)及丙烯酸(Tg：106℃)4質量份(7 mol%)無規共聚合而成之丙烯酸系共聚物(重量平均分子量23萬)1 kg、作為交聯劑之甘油二甲基丙烯酸酯(日油公司製造，製品名：GMR)(b-1)90 g、及作為光聚合起始劑之2,4,6-三甲基二苯甲酮與4-甲基二苯甲酮之混合物(Lanberti公司製造，製品名：Esacure TZT)15 g均勻地混合，而製作黏著片材所使用之樹脂組合物。 利用2片由實施例之群4所示之聚酯膜獲得之離型膜上下夾持所獲得之樹脂組合物(上下之組合設為以相同之離型膜彼此夾持)，使用貼合機以樹脂組合物之厚度成為100 μm之方式賦形為片材狀，而製作黏著片材積層體。再者，以與樹脂組合物相接之方式配置聚酯膜之離型層側。 所獲得之黏著片材積層體係使用真空壓空成形機(第一實業公司製造，FKS-0632-20形)，藉由以下之製程進行熱成形，而製作賦形黏著片材積層體。即，藉由預熱為400℃之IR加熱器，加熱至黏著片材積層體之表面達到100℃，繼而使用冷卻為25℃之成形用模具，於鎖模壓8 MPa之條件下進行5秒之加壓成形，而製作對表面賦形凹凸而成之賦形黏著片材積層體。 將賦形有凹凸之賦形黏著片材積層體之聚酯膜剝離，分別使用掃描式白色干涉顯微鏡，以非接觸方式計測賦形黏著片材之凹部與凸部之高度，將成形體之高度設為h。 計測成形體之凸部相對於模具之深度100 μm之高度h，將由下述計算式導出之轉印率為70%以上者評價為○，將為50%以上且未達70%者評價為△，將未達50%者評價為×。 轉印率(%)＝h(成形體高度)/100(模具深度)×100 (5)黏著層外觀(褶皺) 藉由以下所示之評價方法分別評價藉由(4)所記載之方法獲得之加壓成型前的黏著層積層體之外觀。 ＜評價方法＞ ○：得以無褶皺地層壓，保持良好之外觀。 ×：膜產生褶皺，並且褶皺轉印至黏著層，為無法用作製品之狀態。[表4]

However, the present invention is not limited to the following embodiments. [This adhesive sheet laminate] An adhesive sheet laminate (referred to as "the present adhesive sheet laminate") as an example of an embodiment of the present invention, as shown in Fig. 1 , is provided with an adhesive layer and can be peeled off. Coating part I laminated on one side of the front and back of the adhesive material layer, and adhesive sheet of the covering part II laminated on the other side of the front and back of the adhesive material layer in a peelable manner Laminated body. Here, the covering portion II is arbitrary, and a configuration in which the covering portion II is not laminated may be employed. <Adhesive layer> The adhesive layer of the adhesive sheet laminate is capable of functioning as a double-sided adhesive sheet when the covering portion I and the covering portion II are peeled off, and has a property of softening or melting when heated. Hot melt can be used. The adhesive material layer preferably has a loss tangent tan δ (SA) at 100° C. of 1.0 or more. Moreover, it is preferable that the loss tangent tan delta (SB) at 30 degreeC is less than 1.0. Here, the loss tangent tanδ means the ratio (G''/G') of the loss elastic modulus G'' to the storage elastic modulus G'. Since the temperature at the time of heat-molding the adhesive sheet laminate is usually 70 to 120°C, if the loss tangent tanδ (SA) at 100°C is 1.0 or more, it becomes easy to form uneven shapes on the surface of the adhesive layer. . In addition, if the loss tangent tanδ(SB) of the adhesive material layer at 30°C is less than 1.0, the shape can be maintained under normal conditions, so that the surface of the adhesive material layer can be kept on the surface of the adhesive material layer and conform to the unevenness of the surface of the adherend with high precision. The state of the concave and convex shape. Generally, polymer materials have both viscous properties and elastic properties, and the loss tangent tanδ is above 1.0, and the larger the value, the stronger the viscous properties. On the other hand, the loss tangent tanδ is less than 1.0, and the smaller the value, the stronger the elastic properties. Therefore, by controlling the loss tangent tanδ of the adhesive layer at different temperatures, both formability and shape retention can be achieved. From this viewpoint, the loss tangent tanδ (SA) of the adhesive layer at 100° C. is preferably 1.0 or more, preferably 1.5 or more or 30 or less, and more preferably 3.0 or more or 20 or less. On the other hand, the loss tangent tanδ(SB) of the adhesive layer at 30°C is preferably less than 1.0, preferably 0.01 or more or 0.9 or less, and preferably 0.1 or more or 0.8 or less. Here, the loss tangent tanδ (SA) at 100°C and the loss tangent tanδ (SB) at 30°C of the adhesive layer can be adjusted by adjusting the composition, gel fraction, and weight average of the composition constituting the adhesive layer. The molecular weight etc. are adjusted to the said range. Furthermore, the storage elastic modulus G'(SA) of the adhesive layer at 100° C. is preferably less than 1.0×10 ⁴ Pa. In addition, the storage elastic modulus G'(SB) of the above-mentioned adhesive material layer at 30° C. is preferably 1.0×10 ⁴ Pa or more. If the storage elastic modulus G'(SA) of the adhesive layer at 100°C does not reach 1.0×10 ⁴ Pa is preferable because sufficient formability can be obtained. On the other hand, if the storage elastic modulus G'(SB) of the adhesive layer at 30°C is 1.0×10 ⁴ Pa or more is preferable from the viewpoint of shape stability after molding. From this viewpoint, the storage elastic modulus G'(SA) of the adhesive layer at 100° C. is preferably less than 1.0×10 ⁴ Pa, more preferably 5.0×10 ¹ Pa or more or 5.0×10 ³ Pa or less, and more preferably 1.0×10 ² Pa or more or 1.0×10 ³ Pa or less. Accordingly, the storage elastic modulus G'(SA) of the adhesive layer at 100°C is more preferably 5.0×10 ¹ Pa or more and less than 1.0×10 ⁴ Pa, or 5.0×10 ¹ Pa or more and 5.0×10 ³ Pa or less, and more preferably 1.0×10 ² Pa or more and less than 1.0×10 ⁴ Pa, or 1.0×10 ² Pa or more and 5.0×10 ³ Below Pa, the best is 1.0×10 ² Pa or more and 1.0×10 ³ Pa or less. Moreover, from this viewpoint, the storage elastic modulus G'(SB) of the adhesive layer at 30° C. is preferably 1.0×10 ⁴ Pa or more, and more preferably 2.0×10 ⁴ Pa or more or 1.0×10 ⁷ Pa or less, and more preferably 5.0×10 ⁴ Pa or more or 1.0×10 ⁶ Pa or less. Moreover, according to this, the storage elastic modulus G'(SB) of the adhesive layer at 30° C. is more preferably 1.0×10 ⁴ Pa or more and 1.0×10 ⁷ Pa or less, or 1.0×10 ⁴ Pa or more and 1.0×10 ⁶ Pa or less, more preferably 2.0×10 ⁴ Pa or more and 1.0×10 ⁷ Pa or less, or 2.0×10 ⁴ Pa or more and 1.0×10 ⁶ Below Pa, the best is 5.0×10 ⁴ Pa or more and 1.0×10 ⁶ Pa or less. Here, the storage elastic modulus G'(SA) of the adhesive material layer at 100°C and the storage elastic modulus G'(SB) of the adhesive material layer at 30°C can be adjusted by adjusting the composition of the adhesive material layer. The components, gel fraction, weight average molecular weight, etc. are adjusted to the above ranges. The temperature at which the loss tangent tanδ of the adhesive layer becomes 1.0 is preferably 50 to 150°C, more preferably 60°C or higher or 130°C or lower, and more preferably 70°C or higher or 110°C or lower. If the temperature at which the loss tangent tanδ of the adhesive layer becomes 1.0 is 50 to 150° C., the present adhesive sheet laminate can be preheated to 50 to 150° C. for mold forming. The glass transition temperature (Tg) of the base resin of the adhesive layer is preferably -50 to 40°C, more preferably -30°C or higher or 25°C or lower, and further preferably -10°C or higher or 20°C or lower. Here, the measurement of the glass transition temperature means the midpoint between the inflection points of the baseline movement when the temperature is raised at a rate of 3° C./min using a differential scanning calorimeter (DSC). If the glass transition temperature (Tg) of the base resin of the adhesive material layer is in the above range, the adhesive material layer can be given adhesiveness, and further, the temperature at which the loss tangent tanδ of the adhesive material layer becomes 1.0 can be adjusted to 50 to 150°C. As the material of the adhesive material layer, a previously known adhesive sheet can be used as long as it can be prepared to have a specific viscoelastic behavior. For example, 1) using a (meth)acrylate-based polymer (meaning including a copolymer, hereinafter referred to as "acrylate-based (co)polymer") as a base resin, in which a crosslinking monomer is formulated the adhesive sheet formed by the cross-linking reaction, or 2) using butadiene or isoprene-based copolymer as the base resin, in Among them, the cross-linking monomers, cross-linking initiators or reaction catalysts, etc. are adjusted as needed to make the adhesive sheets formed by cross-linking reaction; or 3) using polysiloxane-based polymers as the base resin, in Wherein, cross-linking monomers, cross-linking initiators or reaction catalysts, etc. are prepared as needed, so that the adhesive sheets formed by the cross-linking reaction, etc. are prepared; or 4) polyurethane-based polymers are used as the basis Resin polyurethane adhesive sheet, etc. The physical properties of the adhesive layer itself are not an essential problem in the present invention except for the above-mentioned viscoelastic properties or thermal properties. However, from the viewpoints of adhesiveness, transparency, and weather resistance, it is preferable to use the acrylate-based (co)polymer of the above 1) as the base resin. When properties such as electrical properties and low refractive index are required, it is preferable to use the butadiene or isoprene-based copolymer of the above 2) as the base resin. When properties such as heat resistance and rubber elasticity in a wide temperature range are required, the polysiloxane-based copolymer of the above 3) is preferably used as the base resin. When properties such as releasability are required, it is preferable to use the polyurethane-based polymer of the above 4) as the base resin. As an example of the said adhesive material layer, what is formed from the resin composition containing the (meth)acrylic type copolymer (a) which is a base resin, a crosslinking agent (b), and a photopolymerization initiator (c) can be illustrated. The adhesive sheet. In this case, it is necessary to satisfy the above-mentioned viscoelastic properties in an uncrosslinked state, that is, in a state before a three-dimensionally crosslinked network structure is formed. From this viewpoint, the gel fraction of the adhesive layer is preferably 40% or less. If the gel fraction of the adhesive material layer is 40% or less, the bonding of molecular chains constituting the adhesive material layer can be suppressed in an appropriate range, so that when it is molded into a shaped adhesive sheet laminate, an appropriate amount of fluidity. From this viewpoint, the gel fraction of the adhesive material layer is preferably 40% or less, particularly preferably 20% or less, and particularly preferably 10% or less. Furthermore, the lower limit of the gel fraction of the adhesive layer is not limited, and may be 0%. In addition, the gel fraction of the above-mentioned adhesive material layer is not limited to the one containing the (meth)acrylic copolymer (a) as the base resin, the crosslinking agent (b), and the photopolymerization initiator (c). In the case of the resin composition, the same applies to the case of using another resin composition as the adhesive layer. ((Meth)acrylic copolymer (a)) The (meth)acrylic copolymer (a) can be further changed depending on the type of the acrylic monomer or methacrylic monomer used for polymerization, the composition ratio, and the Properties such as glass transition temperature (Tg) are appropriately adjusted according to polymerization conditions and the like.

In this case, polymerization is performed using a thermal polymerization initiator or a photopolymerization initiator, etc. starter, through which acrylate copolymers can be obtained. (Acrylic copolymer (A1)) As an example of a preferable base polymer of the adhesive layer, a (meth)acrylic copolymer (A1) containing a graft copolymer having a macromonomer as a branch component can be mentioned . If the above-mentioned acrylic copolymer (A1) is used as the base resin to constitute the adhesive material layer, the adhesive material layer can maintain a sheet shape at room temperature and exhibit self-adhesiveness, and there is a possibility that if it is heated in an uncrosslinked state, it will The hot-melt property of melting or flowing can be further light-hardened, and after light-hardening, it can exert excellent cohesive force and adhere to it. Therefore, if the acrylic copolymer (A1) is used as the base polymer of the adhesive layer, even in an uncrosslinked state, it exhibits adhesiveness at room temperature (20° C.), and has the ability to be heated to 50 to 100° C. ℃, more preferably 60 ℃ or more or 90 ℃ or less temperature will soften or fluidize. The glass transition temperature of the copolymer constituting the main chain component of the acrylic copolymer (A1) is preferably -70 to 0°C. In this case, the glass transition temperature of the copolymer component constituting the main chain component refers to the glass transition temperature of a polymer obtained by copolymerizing only the monomer components constituting the main chain component of the acrylic copolymer (A1). Specifically, it means the value calculated by Fox's calculation formula based on the glass transition temperature and the composition ratio of the polymer obtained from the homopolymer of each component of the copolymer. In addition, the calculation formula of Fox is the calculated value calculated|required by the following formula, and can be calculated|required using the value described in the polymer handbook [Polymer HandBook, J. Brandrup, Interscience, 1989]. 1/(273+Tg)=Σ(Wi/(273+Tgi)) [wherein Wi represents the weight fraction of monomer i, and Tgi represents the Tg (°C) of the homopolymer of monomer i] The glass transition temperature of the copolymer component of the main chain component (A1) will affect the flexibility of the adhesive layer at room temperature, or the wettability of the adhesive layer to the adherend, that is, the adhesiveness. Therefore, in order to adhere The material layer obtains moderate adhesion (tackiness) at room temperature, and the glass transition temperature is preferably -70°C to 0°C, particularly preferably -65°C or above or -5°C, and particularly preferably - Above 60°C or below -10°C. However, even if the glass transition temperature of the copolymer component is the same temperature, the viscoelasticity can be adjusted by adjusting the molecular weight. For example, by reducing the molecular weight of the copolymer component, it can be further softened.

Moreover, it is preferable that the main chain component of an acrylic copolymer (A1) contains a hydrophobic (meth)acrylate monomer and a hydrophilic (meth)acrylate monomer as a structural unit. When the main chain component of the acrylic copolymer (A1) is composed of only a hydrophobic monomer, the tendency of wet heat whitening is observed, so it is preferable to also introduce a hydrophilic monomer into the main chain component to prevent wet heat whitening. Specifically, as the main chain component of the above-mentioned acrylic copolymer (A1), hydrophobic (meth)acrylate monomers, hydrophilic (meth)acrylate monomers, and ends of macromonomers can be mentioned The polymerizable functional group is randomly copolymerized to form a copolymer component.

With such a glass transition temperature (Tg), excellent workability and storage stability can be maintained by adjusting the molecular weight, and it can be adjusted by thermal fusion at around 80°C. The so-called glass transition temperature of the giant monomer refers to the glass transition temperature of the giant monomer itself, which can be measured by a differential scanning calorimeter (DSC). In addition, in order to maintain a state in which the branched components are kept close to each other at room temperature, the adhesive composition is physically cross-linked, and the above-mentioned physical cross-linking can be released by heating to a moderate temperature to obtain fluidity. It is also preferable to adjust the molecular weight or content of the macromonomer. From this point of view, the macromonomer is preferably contained in the acrylic copolymer (A1) in a ratio of 5 to 30 mass %, and is preferably 6 mass % or more or 25 mass % or less, and is preferably It is 8 mass % or more or 20 mass % or less.

Polyfunctional monomers or oligomers with isopolar functional groups. Among them, polyfunctional (meth)acrylates having a hydroxyl group or an amide group are preferably used. From the viewpoint of preventing whitening by moist heat, as the main chain component of the above-mentioned (meth)acrylate copolymer, for example, the graft copolymer, it is preferable to contain a hydrophobic acrylate monomer and a hydrophilic acrylate monomer, Furthermore, as a crosslinking agent, it is preferable to use the polyfunctional (meth)acrylate which has a hydroxyl group. Moreover, in order to adjust the effect, such as adhesiveness, heat-and-moisture resistance, and heat resistance, you may further add the monofunctional or polyfunctional (meth)acrylate which reacts with a crosslinking agent. From the viewpoint of balancing flexibility and cohesion as an adhesive composition, the content of the crosslinking agent is preferably contained in a ratio of 0.1 to 20 parts by mass with respect to 100 parts by mass of the (meth)acrylic copolymer. , the ratio of 0.5 parts by mass or more or 15 parts by mass or less is particularly preferred, and the ratio of 1 part by mass or more or 13 parts by mass or less is particularly preferred. (Photopolymerization initiator (c)) When crosslinking the acrylate polymer, a crosslinking initiator (peroxidation initiator, photopolymerization initiator) or a reaction catalyst (tertiary amine-based compounds, quaternary ammonium compounds, tin laurate compounds, etc.) are more effective. In the case of crosslinking by ultraviolet irradiation, it is preferable to prepare a photopolymerization initiator (c). Photopolymerization initiators (c) are roughly classified into two categories according to the mechanism of generating free radicals, and are roughly divided into: cleavage-type photopolymerization initiators that can break and decompose the single bond of the photopolymerizable initiator itself to generate free radicals ; And the photo-excited initiator forms an excited complex with the hydrogen donor in the system, which can transfer the hydrogen of the hydrogen donor to a hydrogen-abstracting photopolymerization initiator. Among these, the cleavage-type photopolymerization initiator decomposes into other compounds when a radical is generated by light irradiation, and once excited, loses its function as a reaction initiator. Therefore, if the intramolecular cleavage type is used as a photopolymerization initiator having an absorption wavelength in the visible light region, compared with the case of using the hydrogen abstraction type, after the adhesive sheet is cross-linked by light irradiation, the light reacts It is preferable that the photopolymerizable initiator remains as unreacted residue in the present adhesive composition to cause unexpected time-dependent changes in the adhesive sheet or to promote cross-linking. In addition, regarding the coloration peculiar to the photopolymerizable initiator, it is also preferable to select a coloration that disappears absorption in the visible light region by becoming a reaction decomposition product. On the other hand, the hydrogen abstraction type photopolymerization initiator does not generate a decomposition product such as a cleavage type photopolymerization initiator when it is irradiated with active energy rays such as ultraviolet rays to generate a radical reaction, so it is difficult after the reaction is completed. As a volatile component, it can reduce the damage to the adherend. As the above-mentioned cleavage-type photopolymerization initiator, for example, 2,2-dimethoxy-1,2-diphenylethan-1-one, 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy- 2-Methyl-1-phenyl-propan-1-one, 1-(4-(2-hydroxyethoxy)phenyl)-2-hydroxy-2-methyl-1-propan-1-one, 2-Hydroxy-1-[4-{4-(2-Hydroxy-2-methyl-propionyl)benzyl}phenyl]-2-methyl-propan-1-one, oligo(2-hydroxy -2-methyl-1-(4-(1-methylvinyl)phenyl)acetone), methyl phenylglyoxylate, 2-benzyl-2-dimethylamino-1-(4- 𠰌olinylphenyl)butan-1-one, 2-methyl-1-[4-(methylthio)phenyl]-2-𠰌olinylpropan-1-one, 2-(dimethylamino) )-2-[(4-methylphenyl)methyl]-1-[4-(4-𠰌linyl)phenyl]-1-butanone, bis(2,4,6-trimethylbenzene carboxyl)-phenylphosphine oxide, 2,4,6-trimethylbenzyldiphenylphosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenyl oxide Phosphine, bis(2,6-dimethoxybenzyl) 2,4,4-trimethylpentylphosphine oxide, or derivatives thereof, and the like. Among them, bis(2,4,6-trimethylbenzyl)-phenyl is preferable in that it becomes a decomposed product after the reaction by the cleavage-type photopolymerizable initiator and decolorizes Phosphine oxide, 2,4,6-trimethylbenzyldiphenylphosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenylphosphine oxide, bis(2,6 - Dimethoxybenzyl) 2,4,4-trimethylpentylphosphine oxide and other acylphosphine oxide-based photoinitiators. Furthermore, in terms of compatibility with an acrylic copolymer containing a graft copolymer having a macromonomer as a branch component, 2,4,6-trimethylbenzyldiphenyl is preferably used Phosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenylphosphine oxide, bis(2,6-dimethoxybenzyl)2,4,4-trimethyl Amylphosphine oxide and the like are used as photopolymerization initiators. The content of the photopolymerization initiator is not particularly limited. For example, the amount is 0.1 to 10 parts by mass, particularly preferably 0.2 parts by mass or more or 5 parts by mass or less, and particularly preferably 0.5 parts by mass or more or 3 parts by mass with respect to 100 parts by mass of the (meth)acrylic copolymer. The following ratios are included. However, in terms of balance with other elements, it may exceed this range. The photopolymerization initiator may be used alone or in combination of two or more. In addition to the above components, pigments such as pigments or dyes with near-infrared absorption properties, adhesion imparting agents, antioxidants, antiaging agents, moisture absorbing agents, ultraviolet absorbers, silane coupling agents, natural or synthetic agents can also be appropriately formulated as required. Various additives such as resins, glass fibers or glass beads. (Layer Structure and Thickness of Adhesive Material Layer) In addition to a single layer, the adhesive material layer may also be a plurality of layers such as two layers or three layers. Moreover, the adhesive material layer may have a base material layer (layer without adhesiveness) as a core layer, and the structure which laminated|stacked the layer containing an adhesive material on both sides of this base material layer. In the case of such a configuration, the base material layer serving as the core layer preferably has a material or characteristic that enables thermoforming of the adhesive sheet laminate. Moreover, it is preferable that the adhesive material layers other than the base material layer have loss tangent tanδ (SA), loss tangent tanδ (SB), storage elastic modulus G' (SA), and storage elastic modulus G' (SB) above characteristics. The thickness of the adhesive material layer is not particularly limited. Among them, the range of 20 μm to 500 μm is preferable. Within this range, for example, if the adhesive layer is as thin as 20 μm in thickness, it is possible to provide an adhesive sheet excellent in print step followability. Moreover, if it is a thick adhesive material layer such as thickness 500 micrometers, it becomes possible to suppress the overflow of the adhesive material at the time of lamination by shaping|molding in advance the quantity equivalent to a printing level difference. Therefore, the thickness of the adhesive material layer is preferably 20 μm to 500 μm, more preferably 30 μm or more or 300 μm or less, and more preferably 50 μm or more or 200 μm or less. <Coating portion I> As shown in FIG. 1 , the present adhesive sheet laminate is provided with the following coating portion I, which is releasably laminated on one of the front and back surfaces of the adhesive layer, such as the front surface. It is formed on the side of the concave and convex shape. The storage elastic modulus E'(MA) of the covering part I at 100°C is preferably 1.0×10 ⁶ ~2.0×10 ⁹ Pa. Since the temperature during thermoforming of the adhesive sheet laminate is usually 70 to 120°C, the storage elastic modulus E' (MA) at 100°C is 1.0×10 ⁶ ~2.0×10 ⁹ Pa, within the temperature range where the above-mentioned adhesive composition is plasticized to flow, the covering portion I can also be sufficiently deformed to follow the concave-convex shape, not only that, but also the adhesive layer pressed by the covering portion I during molding The surface is formed into the desired concavo-convex shape with high precision, for example, to avoid rounding of the corners. Previously, as a release film laminated on an adhesive sheet, a material with a higher storage elastic modulus, in other words, a "harder" material was often used. The reason is that the properties required for the release film are mainly to protect the adhesive layer and release properties. However, according to the research of the present inventors, it was found that in the new application of thermoforming in the state of laminating a release film on an adhesive sheet, when a new subject of thermoformability is required, it is The above-mentioned physical properties of the film cannot meet the requirements. Therefore, the phenomenon that occurs during thermoforming and the characteristics of the adhesive layer have been investigated in detail, and as a result, it has been found that setting the characteristics different from the conventionally used release films can solve the new problem of thermoformability. beneficial. It has been found that, in particular, the above-mentioned problems can be solved by controlling the storage elastic modulus at a specific temperature within a specific range. From this viewpoint, the storage elastic modulus E' (MA) at 100° C. of the covering portion I is preferably 1.0×10 ⁶ ~2.0×10 ⁹ Pa, more preferably 5.0×10 ⁶ Pa or more or 1.0×10 ⁹ Pa or less, and more preferably 1.0×10 ⁷ Pa or more or 5.0×10 ⁸ Pa or less. Accordingly, the storage elastic modulus E'(MA) of the coating portion I at 100° C. is more preferably 1.0×10 ⁶ ~1.0×10 ⁹ Pa, or 1.0×10 ⁶ ~5.0×10 ⁸ Among them, Pa is more preferably 5.0×10 ⁶ ~2.0×10 ⁹ Pa, or 5.0×10 ⁶ ~1.0×10 ⁹ Pa, the best is 1.0×10 ⁷ ~1.0×10 ⁹ Pa or less, or 1.0×10 ⁷ ~5.0×10 ⁸ Pa. In addition, the storage elastic modulus E' (MB) of the covering portion I at 30° C. is preferably 5.0×10 ⁷ ~1.0×10 ¹⁰ Pa. If the storage elastic modulus E' (MB) of the covering part I at 30°C is 5.0×10 ⁷ ~1.0×10 ¹⁰ Pa can maintain shape retention under normal conditions, so it is easy to handle, such as easy peeling, and not only that, because it is not too hard, it can suppress the formation of unintended unevenness in the adhesive material layer. From this viewpoint, the storage elastic modulus E' (MB) of the covering portion I at 30° C. is preferably 5.0×10 ⁷ ~1.0×10 ¹⁰ Pa, more preferably 1.0×10 ⁸ Pa or more or 8.0×10 ⁹ Pa or less, and more preferably 1.0×10 ⁹ Pa or more or 5.0×10 ⁹ Pa or less. Accordingly, the storage elastic modulus E'(MB) of the covering portion I at 30°C is more preferably 5.0×10 ⁷ ~8.0×10 ⁹ Pa, or 5.0×10 ⁷ ~5.0×10 ⁹ Among them, Pa is more preferably 1.0×10 ⁸ Pa～1.0×10 ¹⁰ Pa, or 1.0×10 ⁸ Pa～8.0×10 ⁹ Pa, the best is 1.0×10 ⁹ ~8.0×10 ⁹ Pa, or 1.0×10 ⁹ ~5.0×10 ⁹ Pa. In order to adjust the storage elastic modulus of the coating portion I at 30° C. and 100° C. as described above, the coating portion I can be adjusted, for example, by adjusting the type of base resin, copolymer resin composition, weight average molecular weight, glass transition temperature, crystallinity, etc. The conditions of the material are adjusted, and the manufacturing conditions such as the presence or absence of stretching, forming conditions, and stretching conditions in the case of stretching are adjusted. However, it is not limited to these methods. Furthermore, it is preferable that the storage elastic modulus E'(MA) of the covering portion I at 100°C and the storage elastic modulus E'(MB) of the covering portion I at 30°C satisfy the following relational expression (1). (1)・・E'(MB)/E'(MA)≧2.0 If the storage elastic modulus E'(MA) of the covering part I at 100°C and the storage elastic modulus E of the covering part I at 30°C '(MB) satisfies the above-mentioned relational expression (1), since sufficient formability can be obtained, which is more preferable. From this viewpoint, E'(MB)/E'(MA)≧2.0 is preferable, and 30≧E'(MB)/E'(MA) or E'(MB)/E' is more preferable. (MA)≧3.0, especially preferably 10≧E'(MB)/E'(MA) or E'(MB)/E'(MA)≧5.0. In order to adjust E'(MB) and E'(MA) to have the above relationship, for example, the type of base resin, copolymer resin component, weight average molecular weight, glass transition temperature, crystallinity, etc. conditions, and adjust the manufacturing conditions such as the presence or absence of stretching, molding conditions, and stretching conditions in the case of stretching. However, it is not limited to these methods.

(2)・・1.0×10 ³ ≦E'(MA)/G'(SA)≦1.0×10 ⁷ If the storage elastic modulus G'(SA) of the adhesive material layer at 100°C and the storage elastic modulus E'(MA) of the coating portion I at 100°C satisfy the above relational expression (2), sufficient The formability is therefore better. From this viewpoint, E'(MA)/G'(SA) is preferably 1.0×10 ³ ~1.0×10 ⁷ , of which 5.0×10 is particularly preferred ³ above or 5.0×10 ⁶ Below, the most preferable one is 1.0×10 ⁴ above or 1.0×10 ⁶ the following. Accordingly, E'(MA)/G'(SA) is more preferably 1.0×10 ³ ~5.0×10 ⁶ , or 1.0×10 ³ ~1.0×10 ⁶ , and more preferably 5.0×10 ³ ~5.0×10 ⁶ , or 5.0×10 ³ ~1.0×10 ⁶ , the best is 1.0×10 ⁴ ~5.0×10 ⁶ , or 1.0×10 ⁴ ~1.0×10 ⁶ . In order to adjust so that E'(MA) and G'(SA) may become the said relationship, what is necessary is just to adjust the characteristic of the adhesive material layer or the coating part I. As a characteristic of an adhesive material layer, for example, it can be achieved by adjusting the component of the composition which comprises an adhesive material layer, a gel fraction, a weight average molecular weight, etc.. In addition, as the properties of the coating portion I, for example, conditions of the material of the coating portion I such as the type of base resin, copolymer resin composition, weight average molecular weight, glass transition temperature, and crystallinity can be adjusted, and the presence or absence of stretching and molding conditions can be adjusted. , In the case of stretching, adjust the manufacturing conditions such as stretching conditions and adjust them. However, it is not limited to these methods. It is preferable that the peeling force F(C) at the time of peeling the said cover part I from the adhesive material layer in 30 degreeC environment about the cover part I is 0.2 N/cm or less. If the peeling force F(C) is 0.2 N/cm or less, the coating portion I described above can be easily peeled off from the adhesive material layer. From this point of view, the peeling force F(C) is preferably 0.2 N/cm or less, more preferably 0.01 N/cm or more or 0.15 N/cm or less, and still more preferably 0.02 N/cm or more or 0.1 N/cm or less.

Preferably it is 0.2 N/cm or less. If the adhesive sheet laminate is heated at 100°C for 5 minutes and then cooled to 30°C, and the peel force F(D) measured at 30°C is the same as the above-mentioned peel force F(C), even if the Even when the adhesive sheet laminate is heated and molded, the peeling force F(D) does not change, so that the coating portion I can be easily peeled off from the adhesive layer. From this viewpoint, the peeling force F(D) is preferably 0.2 N/cm or less, more preferably 0.01 N/cm or more or 0.15 N/cm or less, and more preferably 0.02 N/cm or more or more. 0.1 N/cm or less. Furthermore, it is preferable that the absolute value of the difference of the said peeling force F(C) and the said peeling force F(D) of the coating part I is 0.1 N/cm or less. If the adhesive sheet laminate is heated at 100°C for 5 minutes and then cooled to 30°C, the absolute difference between the peel force F(D) measured at 30°C and the peel force F(C) in the normal state If the value is 0.1 N/cm or less, the peeling force F(D) does not change even when the adhesive sheet laminate is thermoformed, so that the coating portion I can be easily peeled off from the adhesive layer. From this viewpoint, the absolute value of the difference between the peeling force F(C) and the peeling force F(D) is preferably 0.1 N/cm or less, more preferably 0.08 N/cm or less, and still more preferably 0.05 N/cm or less. In addition, the peeling force F(C) and peeling force F(D) of the covering part I can be adjusted by the type of the release layer formed on one side of the covering part I, and the like. However, it is not limited to this method. As a structural example of the coating part I, the structural example provided with a coating base material layer and a release layer is mentioned. By layering the release layer on a single area of the covering base material layer, the covering portion I can be easily peeled off from the adhesive material layer. In this case, the covering base material layer preferably includes, for example, one resin or two or more resins selected from the group consisting of polyester, copolyester, polyolefin, and copolyolefin as a main component. The stretched or unstretched layer, that is, a single layer or a multi-layered layer comprising a stretched or unstretched film with these resins as the main component. Among them, the covering base material layer constituting the above-mentioned covering portion I preferably has, from the viewpoints of mechanical strength, chemical resistance, and the like, an extension comprising, for example, a copolymerized polyester, a polyolefin, or a copolymerized polyolefin as a main component. Or a single layer or multiple layers of layers of unextended film. Specific examples of the above-mentioned copolymerized polyester include isophthalic acid as a dicarboxylic acid, and cyclohexanedimethanol, 1,4-butanediol, and diethylene glycol as a diol. Copolymerized polyethylene terephthalate. As a specific example of the said polyolefin, an alpha-olefin homopolymer is mentioned, for example, a propylene homopolymer or the homopolymer of 4-methylpentene-1 is mentioned. As a specific example of the said polyolefin copolymer, the copolymer of ethylene, propylene, another alpha-olefin, a vinyl monomer, etc. is mentioned, for example. The above-mentioned release layer is preferably a layer containing modified polyolefin in addition to the release agent such as polysiloxane. Here, as a modified olefin which comprises the said release layer, the resin which has as a main component a polyolefin modified with an unsaturated carboxylic acid or its acid anhydride, or a silane type coupling agent is mentioned. Examples of the above-mentioned unsaturated carboxylic acid or anhydride thereof include acrylic acid, methacrylic acid, maleic acid, maleic anhydride, citraconic acid, citraconic anhydride, itaconic acid, itaconic anhydride, or the like. The monoepoxy compound of the derivative and the ester compound of the above-mentioned acid, the reaction product of the polymer having a group capable of reacting with the acid in the molecule, and the acid, etc. Moreover, these metal salts can also be used. Among these, maleic anhydride can be more preferably used. In addition, these copolymers can be used individually or in mixture of 2 or more types. In order to manufacture the modified polyolefin-based resin, for example, these modified monomers may be preliminarily copolymerized at the stage of polymerizing the polymer, or the temporarily polymerized polymer may be graft-copolymerized with these modified monomers. . In addition, as the modified polyolefin-based resin, these modified monomers may be used alone or in combination, and the content thereof is preferably 0.1 mass % or more, preferably 0.3 mass % or more, and more preferably 0.5 mass % or more. It is more than mass % and 5 mass % or less, Preferably it is 4.5 mass % or less, More preferably, it is in the range of 4.0 mass % or less. Among them, graft-modified ones can be suitably used. Suitable examples of the modified polyolefin-based resin include maleic anhydride-modified polypropylene resin, maleic anhydride-modified polyethylene resin, maleic anhydride ethylene-vinyl acetate copolymer, and the like . From the viewpoint of formability, the thickness of the coating portion I is preferably 10 μm to 500 μm, particularly preferably 20 μm or more or 300 μm or less, and especially preferably 30 μm or more or 150 μm or less. <Coating portion II> As described above, the adhesive sheet laminate can be used to laminate the coating portion I releasably on one of the front and back sides of the adhesive material layer, and on the opposite side to the coating portion I, that is, The other side of the front surface and the back surface of an adhesive material layer is the structure which laminated|stacked the coating part II so that peeling was possible. Thereby, workability|operativity can be improved by laminating|stacking the covering part II so that peeling is possible on the other side of the front surface and the back surface of an adhesive material layer. However, it is also possible to employ a configuration in which the coating portion II is not laminated. The material and the structure of the coating portion II are not particularly limited as long as the coating portion II is releasably laminated on the other side of the front surface and the back surface of the adhesive material layer. For example, the coating portion II may have the same laminate structure and material as the coating portion I described above. In this case, the coating portion I may have the same thickness or a different thickness. When the coating portion II has the same laminate structure and material as the coating portion I, it is possible to prevent the occurrence of warpage, etc., when the present adhesive sheet laminate is heated. Covering part II can also have the same structure as covering part I, but the storage elastic modulus E' (MA) at 100°C, the storage elastic modulus E' (MB) at 30°C, and the ratio (E) '(MB)/E'(MA)), peeling force F(C), peeling force F(D), etc. are different from those of the coating portion I. Furthermore, the coating portion II may have a layered structure and material different from those of the coating portion I described above. For the covering portion II, for example, a commonly used release film (also referred to as a "peeling film") can also be used. Specifically, for example, the storage elastic modulus E' (MC) at 100° C. is 2.0×10 ⁹ ~1.0×10 ¹¹ As the material of Pa, for example, a biaxially stretched polyethylene terephthalate (PET) film or the like can be used. [Coating Part I] As a configuration example of the above-mentioned covering part I, the storage elastic modulus E' at 100° C. is 1.5× for a coating film in which a coating layer is provided on one side of a copolymerized polyester film. 10 ⁹ A coating film characterized below Pa (referred to as "the present coating film") will be described. When this coating film is used, for example, after heating the above-mentioned adhesive sheet laminate, the mold can be pressed against the coating film provided with the coating layer having mold release properties, and the adhesive sheet can be formed on the adhesive sheet. The surface is precisely formed in a concavo-convex shape conforming to the concavo-convex portion on the surface of the adherend. Moreover, since the coating film can maintain shape retention under normal conditions, it is easy to handle, and not only that, since it is not too hard, it is possible to suppress the formation of unintended irregularities on the adhesive sheet. <Copolymerized polyester film> The copolymerized polyester film constituting the present coating film may have a single-layer structure or a laminated structure. For example, other than the two-layer and three-layer structures, as long as it does not exceed the gist of the present invention It may be a multilayer of four or more layers, and is not particularly limited. Furthermore, for example, when a three-layer structure (surface layer/intermediate layer/surface layer) is adopted, any one layer of the surface layer or intermediate layer, or any layer of two or more layers may be used as the copolymerized polyester component, and the rest may be used as the copolymerized polyester component. The layer is composed of a polyester component that does not contain a copolymerization component. In addition, the copolymerized polyester film refers to a film obtained by cooling the molten polyester sheet extruded by the extrusion method, and then extending as necessary. As the dicarboxylic acid component of the copolymerized polyester, terephthalic acid is preferred, and other than these, oxalic acid, malonic acid, succinic acid, adipic acid, azelaic acid, sebacic acid, phthalic acid may be contained One or more of known dicarboxylic acids such as dicarboxylic acid, isophthalic acid, naphthalenedicarboxylic acid, diphenyl ether dicarboxylic acid, and cyclohexane dicarboxylic acid are used as a copolymerization component. Moreover, as a glycol component, ethylene glycol is preferable, and propylene glycol, trimethylene glycol, tetramethylene glycol, hexamethylene glycol, 1, 4- cyclohexane may be contained in addition to this One or more of known diols, such as dimethanol, diethylene glycol, triethylene glycol, polyalkylene glycol, and neopentyl glycol, are used as a copolymerization component. Among them, phthalic acid and isophthalic acid as dicarboxylic acid components, 1,4-cyclohexanedimethanol, 1,4-butanediol, and diethylene glycol as diol components are more preferable. Copolymerized polyethylene terephthalate obtained by arbitrary copolymerization. The content of the copolymerization component is preferably 1 mol% or more and 50 mol% or less, more preferably 3 mol% or more or 40 mol% or less, and still more preferably 4 mol% or more or 30 mol% or less. When the content of the copolymerization component is 1 mol% or more, when it is laminated with the adhesive sheet, a concave shape, a convex shape, or a concave and convex shape can be formed on the surface of the adhesive sheet. On the other hand, by being 50 mol% or less, not only sufficient dimensional stability is obtained, but also the generation of wrinkles during processing can be sufficiently suppressed. The melting point of the copolymerized polyester film is preferably designed to be in the range of preferably 260°C or lower, more preferably 200 to 255°C. Since the above-mentioned melting point is 260° C. or lower, sufficient strength can be obtained even in the heat treatment at a temperature lower than the melting point of the copolymerized polyester film in the heat treatment step after stretching. From the viewpoint of improving film workability, it is preferable to contain particles in the copolymerized polyester film. Examples of the particles include inorganic particles such as calcium carbonate, magnesium carbonate, calcium sulfate, barium sulfate, lithium phosphate, magnesium phosphate, calcium phosphate, lithium fluoride, alumina, silicon oxide, and kaolin; acrylic resins, guanamine resins, and the like Organic particles; precipitation particles obtained by granulating catalyst residues, but not limited to these. The particle diameter of these particles or the content in the copolymerized polyester film can be appropriately determined according to the purpose. The particles contained may be a single component, or two or more components may be used simultaneously. In addition, various stabilizers, lubricants, antistatic agents, etc. may be appropriately added. The average particle diameter of the particles contained in the copolymerized polyester film is preferably 0.1 to 5.0 μm. When the average particle diameter of the said particle|grains is less than 0.1 micrometer, the sliding property of a film may become inadequate and workability|operativity may fall. On the other hand, when the average particle diameter of the above-mentioned particles exceeds 5.0 μm, the smoothness of the film surface may be impaired. The content of the particles contained in the copolymerized polyester film is preferably 0.01 to 0.3% by weight. When content of the said particle|grains is less than 0.01 weight%, the sliding property of a film may become inadequate and workability|operativity may fall. On the other hand, when content of the said particle exceeds 0.3 weight%, the smoothness of a film surface may be impaired. It does not specifically limit as a method of adding particle|grains to a copolymerized polyester film, A well-known method can be employ|adopted. For example, it can be added in any stage of polyester production, preferably in the stage of esterification, or can also be added in the form of a slurry dispersed in ethylene glycol or the like after the end of the transesterification reaction and before the start of the polycondensation reaction And the polycondensation reaction is carried out. In addition, the slurry of particles dispersed in ethylene glycol or water can be mixed with polyester raw materials by using a kneading extruder with vent holes, or the dried particles can be mixed using a kneading extruder. A method of blending with a polyester raw material, a method of precipitating particles in a polyester production step system, and the like are performed. The limiting viscosity of the copolymerized polyester is usually 0.40-1.10 dl/g, preferably 0.45-0.90 dl/g, and more preferably 0.50-0.80 dl/g. If the limiting viscosity is less than 0.40 dl/g, the mechanical strength of the film tends to be weakened. When the limiting viscosity exceeds 1.10 dl/g, the melt viscosity may increase, which may cause an excessive load on the extruder. situation. Next, although the production example of a copolymerization polyester film is demonstrated concretely, it is not limited at all to the following production example. Preferably, the method is as follows: First, using the copolyester raw material described above, the molten sheet extruded from the die is cooled and solidified by cooling rolls to obtain an unstretched sheet. In this case, in order to improve the flatness of the sheet, it is necessary to improve the adhesion between the sheet and the rotating cooling drum, and electrostatic application bonding and/or liquid coating bonding can be preferably used. Then, it is preferable to extend the obtained unstretched sheet in at least a uniaxial direction, and it is more preferable to extend biaxially in a biaxial direction. For example, as biaxial stretching, in the case of successive biaxial stretching, the above-mentioned unstretched sheet is stretched in one direction along the machine direction by a stretching machine of a roll or draw-spoke type. The stretching temperature is usually 70 to 120°C, preferably 75 to 110°C, and the stretching ratio is usually 2.5 to 7.0 times, preferably 3.0 to 6.0 times. Next, it extends in a direction perpendicular to the extending direction (machine direction) of the first stage. The stretching temperature is usually 70 to 170°C, and the stretching ratio is usually 3.0 to 7.0 times, preferably 3.5 to 6.0 times. Then, heat treatment is continued at a temperature of 150 to 270° C. under stretching or under relaxation within 30% to obtain a biaxially oriented film. In the above-mentioned biaxial stretching, a method in which the stretching in one direction is carried out in two or more stages may be adopted. In this case, it is preferable to carry out so that the extension magnification of both directions may become the said range finally, respectively. Moreover, regarding manufacture of a copolymerized polyester film, simultaneous biaxial stretching can also be used. Simultaneous biaxial stretching is a method in which the above-mentioned unstretched sheet is simultaneously stretched and aligned in the machine direction and the width direction in a temperature-controlled state at usually 70-120°C, preferably 75-110°C. The stretching ratio is preferably 4 to 50 times, more preferably 7 to 35 times, and still more preferably 10 to 25 times in terms of area ratio. Then, heat treatment is continued at a temperature of 150 to 250° C. under stretching or under relaxation within 30% to obtain a biaxially stretched film. As for the simultaneous biaxial stretching device using the above-described stretching method, a previously known stretching method such as a helical method, a pantograph method, and a linear drive method can be used. (Coating layer) In the present coating film, it is important to provide a coating layer on at least one side of the copolymerized polyester film. It does not specifically limit as a coating layer, Specifically, a release layer, an antistatic layer, an oligomer sealing layer, an easily bonding layer, a primer layer etc. are mentioned. Among them, a release layer is more preferable in terms of producing an adhesive sheet layered product laminated with an adhesive sheet. Moreover, you may combine two or more types of the above-mentioned functional layers. As a specific example of the coating layer constituting the coating film, the release layer will be described below. Specifically, the type of resin used in the release layer includes curable polysiloxane resin, fluorine-based resin, polyolefin-based resin, etc. Among them, curable polysiloxane resin is preferable. It may be a hardening type polysiloxane resin, or a type having a hardening type polysiloxane resin as the main component, and within the scope of not damaging the gist of the present invention, it can also be used by combining with urethane resin, cyclic resin, etc. Modified polysiloxane type obtained by graft polymerization of organic resins such as oxygen resin and alkyd resin. As a kind of hardening type silicone resin, any hardening reaction type, such as an addition type, a condensation type, an ultraviolet curing type, an electron beam curing type, and a solvent-free type, can be used. Specific examples include: KS-774, KS-775, KS-778, KS-779H, KS-847H, KS-856, X-62-2422, X-62 manufactured by Shin-Etsu Chemical Co., Ltd. -2461, X-62-1387, X-62-5039, X-62-5040, KNS-3051, X-62-1496, KNS320A, KNS316, X-62-1574A/B, X-62-7052, X -62-7028A/B, X-62-7619, X-62-7213; YSR-3022, TPR-6700, TPR-6720, TPR-6721, TPR6500, TPR6501, UV9300, UV9425, XS56- A2775, XS56-A2982, UV9430, TPR6600, TPR6604, TPR6605; SRX357, SRX211, SD7220, SD7292, LTC750A, LTC760A, LTC303E, SP7259, BY24-468C, SP7248S, BY24-4 manufactured by Dow Corning Toray Co., Ltd. 202, DKQ3-203, DKQ3-204, DKQ3-205, DKQ3-210, etc. Furthermore, in order to adjust the peelability of a release layer, etc., you may use a peeling control agent together. The curing conditions when the release layer is formed on the copolymerized polyester film are not particularly limited. When the release layer is provided by off-line coating, the heat treatment is usually performed at 120-200° C. for 3-40 seconds, preferably at 100-180° C. for 3-40 seconds. Moreover, active energy ray irradiation, such as heat processing and ultraviolet irradiation, can also be used together as needed. In addition, as an energy source for hardening by active energy ray irradiation, a conventionally known apparatus and energy source can be used. The coating amount of the release layer (after drying) is usually 0.005 to 1 g/m in terms of coatability ² range, preferably 0.005 to 0.5 g/m ² range, more preferably 0.01 to 0.2 g/m ² range. Less than 0.005 g/m in coating amount (after drying) ² In such a case, stability may be lacking in coating properties, and it may be difficult to obtain a uniform coating film. On the other hand, in excess of 1 g/m ² On the other hand, in the case of thick coating, the coating film adhesion, curability, etc. of the release layer itself may decrease. As a method of providing a release layer on the copolymerized polyester film, previously known reverse gravure coating, direct gravure coating, roll coating, die coating, bar coating, curtain coating, etc. can be used the coating method. Regarding the coating method, there is an example described in "Coating Method" (Written by Maki Shoten Isamaki Harasaki, published in 1979). Moreover, in order to provide a coating layer in the copolymerized polyester film, surface treatment, such as corona treatment, plasma treatment, and ultraviolet irradiation treatment, may be performed in advance. (Coating film) The thickness of this coating film is usually 9 μm to 250 μm, preferably 12 μm to 125 μm, and more preferably 25 μm to 75 μm. When the above-mentioned thickness is less than 9 μm, the film tension becomes insufficient, and an abnormality such as wrinkles is likely to occur at the time of slitting. On the other hand, if it exceeds 250 μm, for example, the followability to a molded product having a curved shape may become insufficient. The storage elastic modulus E' of the coating film at 100°C is 1.5×10 ⁹ Pa or less, preferably 1.0×10 ⁹ Pa or less. By the above storage elastic modulus E' is 1.5 × 10 ⁹ Pa or less, when it is laminated with an adhesive sheet, a concave shape, a convex shape, or a concave-convex shape can be formed on the surface of the adhesive sheet. In order to make the storage elastic modulus E' at 100 degreeC satisfy|fill the said range, it can satisfy by adjusting the kind and content of the copolymerization component contained in the copolymerization polyester film. On the other hand, the lower limit is not particularly limited, but is preferably 1.0×10 ⁷ Pa or more, more preferably 1.0×10 ⁸ Pa or more. The shrinkage ratio of the coating film after heating at 120° C. for 5 minutes is 3.0% or less, preferably 2.5% or less. Since the above-mentioned shrinkage ratio is 3.0% or less, it has sufficient dimensional stability, so that when it is laminated with an adhesive sheet, a concave shape, a convex shape, or a concave-convex shape can be formed on the surface of the adhesive sheet. Furthermore, since the generation of wrinkles during processing can be suppressed, the wrinkles are not transferred to the adhesive sheet, and an adhesive sheet having a sufficient appearance can be produced. Among them, the shrinkage in the machine direction (MD) after heating at 120° C. for 5 minutes is preferably 3.0% or less, more preferably 2.5% or less. On the other hand, it does not specifically limit as a lower limit, Preferably it is 0.1% or more, More preferably, it is 0.5% or more. Moreover, after heating at 120 degreeC for 5 minutes, the shrinkage rate of the direction (TD) perpendicular|vertical to a machine direction becomes like this. Preferably it is 1.0 % or less, More preferably, it is 0.8 % or less. On the other hand, as a lower limit, -1.0% or more is preferable, and -0.5% or more is more preferable. From the viewpoint of preventing contamination caused by the adhesion of the oligomer (cyclic trimer) to the mold during the molding process of the coating film, it is preferable that the oligomer is removed from the coating after the heat treatment (180° C., 10 minutes). The amount of extraction on the surface of the layer is 1.0×10 ^-3 mg/cm ² or less, more preferably 5.0×10 ^-4 mg/cm ² the following. When the above-mentioned oligomer extraction amount exceeds this range, contamination due to adhesion of the oligomer to the mold during molding may become serious. As an example, in the process of multiple continuous heating and molding, the deposition of precipitated oligomers promotes mold contamination, so it is important to control the amount of oligomers precipitated during heating. For the above-mentioned reasons, it is preferable that the extraction amount of the above-mentioned oligomer is as small as possible. THE MANUFACTURING METHOD OF THE PRESENT ADHESIVE LAMINATED BODY As an example of the manufacturing method of the present adhesive sheet laminated body, the following method is mentioned, for example: The adhesive composition is sandwiched between two covering parts I or II, and a laminating machine is used. An adhesive layer is formed. Moreover, as another method, the method of apply|coating an adhesive composition to the coating part I or II, and forming an adhesive material layer is mentioned. However, it is not limited to this manufacturing method. As a method of coating the adhesive composition, for example, conventionally known coating methods such as reverse roll coating, gravure coating, bar coating, and blade coating are exemplified.

The present shaping adhesive sheet laminate 1 having such a structure can be integrated by subjecting the above-mentioned present adhesive sheet laminate to pressure forming, vacuum forming, air pressure forming or roll forming, as shown in FIG. 2 . The present pressure-sensitive adhesive sheet laminate is produced by forming a concavo-convex shape. By manufacturing in the above-described manner, the surface unevenness 2B of the adhesive sheet of the adhesive layer 2, the surface unevenness 3B of the protective sheet of the covering portion 1, and the unevenness 3D of the back surface of the protective sheet can be formed corresponding to the same position respectively to form unevenness. The adhesive layer 2 can be used, for example, as a double-sided adhesive sheet for laminating two image display device constituent members (respectively referred to as "adhered bodies") constituting the image display device. That is, the concave and convex portion 2B on the surface of the adhesive sheet in the above-mentioned adhesive material layer 2 may be in a manner that corresponds to the concave portion, convex portion or concave and convex portion (referred to as "surface concave and convex portion of the adherend") in the bonding surface of the above-mentioned adherend It is preferably formed in the same outline shape.

In addition, the image display device constituting member as the adherend is a member constituting these image display devices, for example, a surface protection panel, a touch panel, an image display panel, etc. 1 can be used to bond any two adherends selected from a surface protection panel, a touch panel, and an image display panel, for example. For example, it can be used for bonding a surface protection panel and a touch panel, or a touch panel and an image display panel. However, the adherend is not limited to these. <Manufacturing method> Here, the manufacturing method of this shaping|molding adhesive sheet laminated body 1 is demonstrated in detail. As described above, as shown in FIG. 2 , the present adhesive sheet layered body 1 can be integrally molded into a concavo-convex shape by heating the present adhesive sheet layered body to be produced. In this case, as a forming method, for example, press forming, vacuum forming, air pressure forming, forming by roll, forming by lamination, etc. are mentioned. Among them, press forming is particularly preferred from the viewpoint of formability and workability. A more detailed specific example will be described. The adhesive sheet laminate is preheated by a heater, and the adhesive sheet laminate is transported to a press molding machine at the stage of heating to a specific temperature, and the uneven shape corresponding to the printing step shape of the to-be-adhered body is imitated in advance. The mold is press-processed and cooled at the same time, so that the shape of the mold can be transferred to one side of the adhesive sheet laminate, and the present shaped adhesive sheet laminate 1 having concavities and convexities formed on one side is produced. At this time, the preheating of the adhesive sheet laminate is preferably heated to a temperature at which the adhesive layer is softened, and specifically, it is preferably heated at 70 to 120°C. The material of the mold used for concave-convex forming is not particularly limited. For example, resin-based materials such as polysiloxane and fluororesin, metal-based materials such as stainless steel and aluminum, and the like can be mentioned. Among them, since high-precision formability is required for the concavo-convex forming of the adherend, a metal-based mold capable of controlling the temperature during forming is particularly preferred. In addition, the cooling after the press working may be performed after the mold is opened, or the mold may be cooled in advance, and the cooling may be performed simultaneously with the pressurization.

[Manufacturing Method of the Present Shaped Adhesive Sheet Laminated Product] Next, a covering portion 1 having an adhesive material layer and laminated on one surface of the adhesive material layer in a peelable manner is provided on one surface of the adhesive material. A particularly preferred embodiment of the method for producing a shaped adhesive sheet laminate having a configuration of concave portions, convex portions, or concave-convex portions (referred to as "adhesive layer surface concavo-convex portions") will be described. Inventions related to the present manufacturing method 1 and the present manufacturing method 2 described below propose a surface concavo-convex portion of the adhesive material layer that can be formed on the surface of the adhesive material layer with high precision and conforming to the concavo-convex portion on the surface of the adherend, preferably A method for producing a novel shape-forming adhesive sheet laminate that can be produced continuously. As an example of an embodiment of the present invention, a novel manufacturing method of a shaped pressure-sensitive adhesive sheet laminate (referred to as "this manufacturing method 1") is proposed. A structure formed by laminating the coating part I on one side of the adhesive material layer by peeling, and forming a concave part, a convex part or a concave-convex part (referred to as "the surface concave-convex part of the adhesive material layer") on one surface of the adhesive material The manufacturing method is characterized in that it comprises an adhesive material layer and a covering portion 1 formed by peeling the adhesive layer laminated on one side of the adhesive material layer, and heating the adhesive sheet laminate to heat the heated adhesive sheet layered body. An adhesive sheet laminate is formed and cooled to produce a manufacturing method for a shaped adhesive sheet laminate, and the adhesive sheet laminate is heated, and the storage elastic modulus E' (MS) in the coating portion I is 1.0× 10 ⁶ ~2.0×10 ⁹ Forming started in the state of Pa, and the storage elastic modulus E' (MF) of the covering part I was 5.0×10 ⁷ ~1.0×10 ¹⁰ The forming is completed in the state of Pa. In the present manufacturing method 1, a method for manufacturing the above-mentioned novel shaped adhesive sheet laminate is further proposed, which uses a cooled mold for forming the heated adhesive sheet laminate. According to the present manufacturing method 1, for example, after the above-mentioned adhesive sheet laminate is heated, the covering part I starts to be formed in a specific state, and the covering part I finishes forming in a specific state, so that the surface of the adhesive layer can be formed with high precision. A concave-convex shape corresponding to the concave-convex portion on the surface of the adherend is formed. Furthermore, when molding the heated adhesive sheet laminate, if molding is performed using a cooled mold, cooling can be performed at the same time as molding and it can be completed at the same time, so that the above-described manufacturing method can be continuously performed. <This production method 1> This production method 1 is a production method (referred to as "the present production method") of a shaped pressure-sensitive adhesive sheet layered product as an example of the present embodiment, which includes heating the pressure-sensitive adhesive sheet layered body (heating step) described below. ), the manufacturing method of the steps of forming the heated adhesive sheet laminate and cooling (forming and cooling steps). The present manufacturing method 1 may include other steps as long as the above-mentioned heating step and the above-mentioned forming and cooling steps are included. For example, if necessary, steps such as a heat treatment step, a conveying step, a slitting step, and a cutting step are included. But it is not limited to these steps. (Adhesive sheet laminate) The adhesive sheet laminate serving as the starting member in the manufacturing method 1 may include an adhesive layer and a coating portion 1 formed by releasably laminated on one surface of the adhesive layer, Other components may also be provided. For example, as shown in FIG. 1, it is possible to exemplify a coating portion I including an adhesive layer, laminated on one of the front and back sides of the adhesive layer in a releasable manner, and laminated on the adhesive in a releasable manner. The adhesive sheet laminate of the covering portion II formed from the other side of the front and back surfaces of the material layer. However, whether or not the covering portion II is provided is optional, and a configuration in which the covering portion II is not laminated may be adopted. In addition, the details of the adhesive sheet laminate are as described above. (Heating step) In the present manufacturing method 1, it is preferable to heat the above-mentioned adhesive sheet laminate so that the storage elastic modulus E' (M) of the covering portion I is 1.0×10 ⁶ ~2.0×10 ⁹ The state of Pa. If the storage elastic modulus E′(M) of the covering portion I is in the above-mentioned range, the covering portion I can be deformed to an extent suitable for molding, and the surface of the adhesive material layer can be shaped into a desired concavo-convex shape with high accuracy . From this viewpoint, it is preferable that the storage elastic modulus E' (M) of the coating portion I is 1.0×10 by heating the adhesive sheet laminate. ⁶ ~2.0×10 ⁹ The state of Pa, which is more preferably set to 5.0×10 ⁶ Pa or more or 1.0×10 ⁹ The state of Pa or less is more preferably set to 1.0×10 ⁷ Pa or more or 5.0×10 ⁸ A state below Pa. Accordingly, it is more preferable that the storage elastic modulus E' (M) of the covering portion I be 1.0×10 by heating the adhesive sheet laminate. ⁶ ~1.0×10 ⁹ Pa, or 1.0×10 ⁶ ~5.0×10 ⁸ The state of the ⁶ ~2.0×10 ⁹ Pa, or 5.0×10 ⁶ ~1.0×10 ⁹ The state of Pa is best set to 1.0×10 ⁷ ~1.0×10 ⁹ Pa, or 1.0×10 ⁷ ～～5.0×10 ⁸ state. Here, in order to adjust the storage elastic modulus E'(M) of the covering portion 1 so as to be in the above-mentioned range in order to heat the adhesive sheet laminate, it can be adjusted according to the composition or the gel fraction of the composition constituting the covering portion 1. The ratio, weight average molecular weight, etc. are adjusted by adjusting the heating temperature. However, it is not limited to this method. Furthermore, it is more preferable to heat the above-mentioned adhesive sheet laminate so that the storage elastic modulus E' (M) of the covering portion I is 1.0×10 ⁶ ~2.0×10 ⁹ Pa, and the storage elastic modulus G'(S) of the adhesive layer is less than 1.0×10 ⁴ The state of Pa. If the storage elastic modulus E'(M) of the coating portion I is adjusted to the above range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G'(S) of the adhesive material layer is less than 1.0 ×10 ⁴ With Pa, sufficient formability can be imparted to the adhesive layer. From this point of view, it is preferable that the storage elastic modulus E'(M) of the covering portion I is within the above range and the storage elastic modulus G'(S) of the adhesive layer is less than 1.0×10 ⁴ The state of Pa, which is preferably set to 5.0×10 ¹ Pa or more or 5.0×10 ³ The state of Pa or less, preferably 1.0×10 ² Pa or more or 1.0×10 ³ A state below Pa. Accordingly, it is more preferable to heat the adhesive sheet laminate so that the storage elastic modulus E'(M) of the covering portion I is in the above range and the storage elastic modulus G'(S) of the adhesive layer is 5.0×10 ¹ Pa or more and less than 1.0×10 ⁴ Pa, or 5.0×10 ¹ Pa or more and 5.0×10 ³ The state of Pa or less is more preferably set to 1.0×10 ² Pa or more and less than 1.0×10 ⁴ Pa, or 1.0×10 ² Pa or more and 5.0×10 ³ In the state of less than Pa, it is best to set it as 1.0×10 ² Pa or more and 1.0×10 ³ A state below Pa. Here, the storage elastic modulus G'(S) of the adhesive material layer can be adjusted by adjusting the heating temperature according to the composition, gel fraction, weight average molecular weight, etc. of the composition constituting the adhesive material layer. However, it is not limited to this method. Furthermore, it is especially preferable to heat the adhesive sheet laminate so that the value of the loss tangent tanδ of the adhesive layer becomes 1.0 or more. In addition, the loss tangent tanδ will be described below. If the value of the loss tangent tanδ of the adhesive material layer is 1.0 or more, it is preferable because it has a degree of flexibility that can be formed. From this point of view, it is particularly preferable to heat the adhesive sheet laminate so that the value of the loss tangent tanδ of the adhesive layer becomes 1.0 or more, more preferably 1.5 or more or 20 or less, and still more preferably To make it 3.0 or more or 10 or less. But the upper limit is not limited to this. In this manufacturing method 1, it is preferable to heat the adhesive sheet laminated body so that the surface temperature of the coating part I may become 70-180 degreeC. When the surface temperature of the covering portion I is 70° C. or higher, the adhesive material layer is sufficiently softened and the covering portion I can be sufficiently deformed. It is preferable because of the disadvantages such as the decomposition of the adhesive material layer. From this viewpoint, it is preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70 to 180°C, more preferably 75°C or higher or 150°C or lower, and more preferably It becomes 80 degreeC or more or 120 degreeC or less. As a method of heating the adhesive sheet laminate, for example, a method of heating the adhesive sheet laminate between upper and lower heating plates equipped with a heating body such as an electric heater inside and heating from the upper and lower sides, or a method of directly sandwiching the adhesive sheet laminate The method of holding, the method of using a heating roller, the method of immersing it in hot water, etc. However, it is not limited to these methods. (Shaping and cooling step) In this step, the heated adhesive sheet laminate is formed as described above, and cooling is performed while the adhesive sheet laminate is being formed. That is, the pressure-sensitive adhesive sheet layered body in which the pressure-sensitive adhesive layer and the covering portion I are integrated is directly formed. As a result, the covering portion I is formed by the die, and the adhesive material layer is also formed through the covering portion I. In this step, cooling may be performed after molding the heated adhesive sheet laminate, or cooling may be performed simultaneously with molding. For example, by pressing with a cooled mold, forming and cooling can be performed at the same time and finished at the same time. Thereby, the present manufacturing method 1 can be continuously implemented as described below. As the molding method, the molding method is not particularly limited as long as the pressure-sensitive adhesive sheet laminate can be integrally formed with a concavo-convex shape. For example, press forming, vacuum forming, air pressure forming, forming by roll, compression forming, forming by lamination, etc. are mentioned. Among them, press forming is particularly preferred from the viewpoint of formability and workability. The material of the mold is not particularly limited. For example, resin-based materials such as polysiloxane and fluororesin, metal-based materials such as stainless steel and aluminum, and the like can be mentioned. Among them, since high-precision formability is required for the concavo-convex forming of the adherend, a metal-based mold capable of controlling the temperature during forming is particularly preferred. As the cooling method of the mold, a conventional cooling method can be adopted. For example, water cooling or a cooling method using compressed air is exemplified. For the mold, for example, as shown in FIG. 2, a specific concave-convex shape is preliminarily arranged on the inner wall surface of at least one of the open and closed pair of molds, for example, provided with the surface of the adherend of the adhesive layer. The concavo-convex shape conforming to the concave portion, convex portion, or concave-convex portion, and the above concave-convex shape can be transferred to the adhesive sheet by subjecting the adhesive sheet laminate to pressure forming, vacuum forming, air pressure forming or roll forming using the mold The material is laminated and shaped. In this step, preferably as described above, the storage elastic modulus E' (MS) of the covering portion I in the adhesive sheet laminate is 1.0×10 ⁶ ~2.0×10 ⁹ It begins to take shape in the state of Pa. Here, "starting molding" means, for example, in the case of molding using a mold, the mold is closed, and the pressure-sensitive adhesive sheet laminate is started to be pressed by the mold. If the storage elastic modulus E'(MS) of the covering part I is 1.0×10 ⁶ ~2.0×10 ⁹ In the range of Pa, the covering portion I can be deformed to an extent suitable for forming, and the surface of the adhesive material layer can be formed into a desired concavo-convex shape with high precision. From this viewpoint, the storage elastic modulus E'(MS) in the covering portion I is preferably 1.0×10 ⁶ ~2.0×10 ⁹ In the state of Pa, the forming of the adhesive sheet laminate is started, and it is more preferably 5.0×10 ⁶ Pa or more or 1.0×10 ⁹ Forming is started at a state of Pa or less, preferably 1.0×10 ⁷ Pa or more or 5.0×10 ⁸ Forming starts at a state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the covering portion I be 1.0×10 ⁶ ~1.0×10 ⁹ Pa, or 1.0×10 ⁶ ~5.0×10 ⁸ In the state of Pa, the forming of the adhesive sheet laminate is started, and it is more preferably 5.0×10 ⁶ ~1.0×10 ⁹ Pa, or 5.0×10 ⁶ ~5.0×10 ⁸ It starts to form in the state of Pa, the best is 1.0×10 ⁷ ~1.0×10 ⁹ Pa, or 1.0×10 ⁷ ~5.0×10 ⁸ It begins to take shape in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MS) in the coating portion I is 1.0×10 ⁶ ~2.0×10 ⁹ Pa, and the storage elastic modulus G'(SS) of the adhesive layer is less than 1.0×10 ⁴ In the state of Pa, the forming of the adhesive sheet laminate is started. If the molding is started in a state where the storage elastic modulus E' (MS) of the coating part I is in the above-mentioned range, the above-mentioned effects can be obtained. In addition to this, if the storage elastic modulus G' ( SS) less than 1.0×10 ⁴ When molding is started in the state of Pa, the molding can be performed in a state in which the adhesive layer has more sufficient formability. From this viewpoint, it is further preferable that the storage elastic modulus E'(MS) of the coating portion I is in the above-mentioned range and the storage elastic modulus G'(SS) of the adhesive material layer is less than 1.0×10 ⁴ Forming starts in the state of Pa, and it is more preferable that the G'(SS) is 5.0×10 ¹ Pa or more or 5.0×10 ³ Forming is started in a state of less than Pa, more preferably 1.0×10 ² Pa or more or 1.0×10 ³ Forming starts at a state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the coating portion I is in the above-mentioned range, and the storage elastic modulus G'(SS) of the adhesive layer is 5.0×10 ¹ Pa or more and less than 1.0×10 ⁴ Pa, or 5.0×10 ¹ Pa or more and 5.0×10 ³ Forming is started in a state of Pa or less, and more preferably, it is 1.0×10 ² Pa or more and less than 1.0×10 ⁴ Pa, or 1.0×10 ² Pa or more and 5.0×10 ³ Forming starts at a state of less than Pa, preferably 1.0×10 ² Pa or more and 1.0×10 ³ Forming starts at a state below Pa. Moreover, it is preferable to start shaping|molding in the state which the surface temperature of the said coating part I is 70-180 degreeC. When the surface temperature of the covering portion I is 70° C. or higher, the adhesive material layer is sufficiently softened and the covering portion I can be sufficiently deformed. It is preferable because of the disadvantages such as decomposition of the adhesive material layer caused by heat. Therefore, it is preferable to start molding in a state where the surface temperature of the coating portion I is 70 to 180°C, more preferably 75°C or higher or 150°C or lower, and still more preferably 80°C or higher or 120°C ℃ or lower. On the other hand, in this step, it is preferable that the storage elastic modulus E'(MF) of the covering portion I is 5.0×10 ⁷ ~1.0×10 ¹⁰ The forming is completed in the state of Pa. Here, "finishing the molding" means ending the application of the molding pressure to the adhesive sheet laminate, and in the case of mold molding, it means opening the mold. If the storage elastic modulus E' (MF) of the above-mentioned covering part I is 5.0×10 ⁷ Pa or more and 1.0×10 ¹⁰ The range below Pa is preferable because the shape stability after molding is excellent. From this viewpoint, it is preferable that the storage elastic modulus E'(MF) in the above-mentioned covering portion I is 5.0×10 ⁷ ~1.0×10 ¹⁰ Finish the forming in the state of Pa, which is more preferably 1.0×10 ⁸ Pa or more or 8.0×10 ⁹ The molding is completed in a state of less than Pa, more preferably 1.0×10 ⁹ Pa or more or 5.0×10 ⁹ The molding is completed in a state of less than Pa. Accordingly, in this step, it is more preferable that the storage elastic modulus E'(MF) of the covering portion I is 5.0×10 ⁷ ~8.0×10 ⁹ Pa, or 5.0×10 ⁷ ~5.0×10 ⁹ The forming is completed in the state of Pa, among which, it is preferably 1.0×10 ⁸ ~8.0×10 ⁹ Pa, or 1.0×10 ⁸ ~5.0×10 ⁹ Finish the forming in the state of Pa, the best is 1.0×10 ⁹ ~8.0×10 ⁹ Pa, or 1.0×10 ⁹ ~5.0×10 ⁹ The forming is completed in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MF) of the coating portion I is in the above-mentioned range, and the storage elastic modulus G'(SF) of the adhesive layer is 1.0×10 ⁴ The molding is completed in a state of Pa or more. If the molding is completed in a state where the storage elastic modulus E' (MF) of the coating portion I is in the above-mentioned range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G' of the adhesive layer is (SS) is 1.0×10 ⁴ When the molding is completed in a state of Pa or higher, the shape of the formed adhesive layer can be maintained. From this viewpoint, it is preferable that the storage elastic modulus E'(MF) of the coating portion I is in the above-mentioned range, and the storage elastic modulus G'(SF) of the adhesive material layer is 1.0×10 ⁴ The molding is completed in a state of Pa or higher, and it is further preferable that the storage elastic modulus G'(SF) of the adhesive layer is 5.0×10 ⁴ Pa or more or 5.0×10 ⁷ The molding is completed in a state of Pa or less, and more preferably, it is 1.0×10 ⁴ Pa or more or 1.0×10 ⁷ The molding is completed in a state of less than Pa. Moreover, it is preferable to complete|finish shaping|molding in the state which the surface temperature of the said coating part I became less than 50 degreeC. For example, in the case of press molding, it is preferable to open the mold in a state where the surface temperature does not reach 50°C. If the surface temperature of the covering part I is less than 50°C, and the storage elastic modulus E' (MS) of the covering part I is 5.0×10 ⁷ ~1.0×10 ¹⁰ The range of Pa is preferable because deformation when the molded body is taken out after molding, or warpage due to thermal shrinkage of the covering portion I can be suppressed. From this point of view, it is preferable to finish the molding in a state where the surface temperature of the coating portion I is less than 50°C, and it is preferable to finish the molding in a state where the surface temperature is 0°C or higher or 45°C or lower. The molding is completed in a state of 10°C or higher or 40°C or lower. Furthermore, it is preferable that the storage elastic modulus E' (MS) of the covering portion I at the start of the molding and the storage elastic modulus E' (MF) of the covering portion I at the end of the molding satisfy the following relational expression (1) . (1)・・E'(MF)/E'(MS)≧1.3 Here, if the storage elastic modulus E'(MS) of the above-mentioned coating portion I and the above-mentioned storage elastic modulus of the coating portion I at the end of molding E'(MF) satisfies the above-mentioned relational expression (1), is soft enough to be able to be formed at the beginning of forming, and has a hardness of such a degree that the formed shape can be maintained after the forming is completed, so it is preferable. From this viewpoint, E'(MF)/E'(MS)≧1.3 is preferable, and 100≧E'(MF)/E'(MS) or E'(MF)/E' is more preferable. (MS)≧3.0, particularly preferably 50≧E'(MF)/E'(MS) or E'(MF)/E'(MS)≧5.0. However, the upper limit of E'(MF)/E'(MS) is not limited to this. Moreover, it is preferable that the storage elastic modulus E' (MF) of the coating portion I at the completion of the molding and the storage elastic modulus G' (SF) of the adhesive layer at the completion of the molding satisfy the following relational expression (2) . (2)・・E'(MF)/G'(SF)≦1.0×10 ⁷ Here, if the storage elastic modulus E' (MF) of the covering portion I at the completion of the forming and the storage elastic modulus G' (SF) of the adhesive layer at the completion of the forming satisfy the above-mentioned relational expression (2), then The formed adhesive material layer can maintain the shape. From this viewpoint, it is preferable that E'(MF)/G'(SF)≦1.0×10 ⁷ , which is more preferably 1.0≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦5.0×10 ⁶ , which is more preferably 1.0×10 ¹ ≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦1.0×10 ⁶ . Although there are repetitions, in the present manufacturing method 1, the mold may be press-molded and cooled after the mold is opened, or the mold may be cooled in advance and cooled simultaneously with the press-molding. If the mold is cooled in advance in this way, and the cooling is performed simultaneously with the press molding, the molding and cooling can be completed at the same time. Thereby, the shaped adhesive sheet laminate can be conveyed to the next step immediately after the completion of forming and cooling, so that the shaped adhesive sheet laminate can be continuously produced. In the case of cooling at the same time as the molding of the mold, the surface temperature of the mold is preferably 0 to 50°C. If the surface temperature of the mold is 50°C or lower, the shape of the adhesive sheet laminate can be fixed in a short time, the obtained molded body can be obtained with high precision, and warpage accompanying thermal shrinkage during cooling after molding can be suppressed. It is better from this point of view. Therefore, the surface temperature of the mold is preferably 0 to 50°C, more preferably 10°C or higher or 40°C or lower, and more preferably 15°C or higher or 30°C or lower. In addition, the conditions of press-molding, such as press pressure and press time, are not specifically limited, What is necessary is just to adjust suitably according to the size and shape to be molded, the material to be used, and the like. (Others) The shaped pressure-sensitive adhesive sheet laminate obtained in the above-mentioned forming and cooling steps can be directly wound up, heat-treated, or cut into a specific size and shape. At the time of cutting, the method of cutting using a Thomson blade, a rotary cutter, etc. is mentioned, for example. In this manufacturing method 1, it is preferable to manufacture a shaping|molding adhesive sheet laminated body continuously. For example, the adhesive sheet laminate may be conveyed to a heating unit such as a heater, and the conveyance may be stopped for a predetermined time in the heating unit to heat, or the heated adhesive sheet laminate may be conveyed to molding after being heated while conveying. A unit, such as a forming die, in the forming unit, for example, pressurized by a cooled die, cooled at the same time as forming, and then transported to the next unit as necessary to continuously manufacture a shaped adhesive sheet Laminated body. <The present manufacturing method 2> As an example of the embodiment of the present invention, there is proposed a method for manufacturing a shaped adhesive sheet laminate (referred to as "the present manufacturing method 2"), the shaped adhesive sheet laminate system having an adhesive material. Layer and the coating part I formed by laminating one surface of the adhesive material layer in a peelable manner, and forming concave parts, convex parts or concave and convex parts on one surface of the adhesive material (referred to as "the surface concave-convex part of the adhesive material layer") The characteristics of the manufacturing method include heating an adhesive sheet laminate having an adhesive material layer and a covering portion I formed by peeling the adhesive material layer on one surface of the adhesive material layer, using A method of manufacturing a shaped adhesive sheet laminate by molding the heated adhesive sheet laminate with a mold, heating the adhesive sheet laminate, and starting in a state where the surface temperature of the coating portion I is 70 to 180° C. After molding, after the surface temperature of the coating portion I became less than 60° C., the shaped pressure-sensitive adhesive sheet laminate was taken out from the mold. According to the present manufacturing method 2, by heating the adhesive sheet laminate, molding is started in a state where the surface temperature of the covering portion I is 70 to 180° C., and after the surface temperature of the covering portion I becomes less than 60° C., it is removed from the mold. By taking out the shaped adhesive sheet laminate, for example, on the surface of the adhesive layer, a concavo-convex shape corresponding to the concavo-convex portion on the surface of the adherend can be formed with high precision. This manufacturing method 2 is a manufacturing method including the steps of heating the adhesive sheet laminate described below (heating step), molding the heated adhesive sheet laminate, and cooling (forming, cooling step). The present manufacturing method 2 may include other steps as long as the above-mentioned heating step and the above-mentioned forming and cooling steps are included. For example, if necessary, steps such as a heat treatment step, a conveying step, a slitting step, and a cutting step are included. But it is not limited to these steps. (Adhesive sheet laminate) The adhesive sheet laminate serving as the starting member in the present manufacturing method 2 may include an adhesive layer and a coating portion 1 formed by releasably laminated on one surface of the adhesive layer, Other components may also be provided. For example, as shown in FIG. 1, it is possible to exemplify a coating portion I including an adhesive layer, laminated on one of the front and back sides of the adhesive layer in a releasable manner, and laminated on the adhesive in a releasable manner. The adhesive sheet laminate of the covering portion II formed from the other side of the front and back surfaces of the material layer. However, whether or not the covering portion II is provided is optional, and a configuration in which the covering portion II is not laminated may be adopted. In addition, the details of the adhesive sheet laminate are as described above. (Heating process) In this process, the said adhesive sheet laminated body is heated so that the surface temperature of the coating part I may become 70-180 degreeC. When the surface temperature of the covering portion I is 70° C. or higher, the adhesive material layer is sufficiently softened and the covering portion I can be sufficiently deformed. It is preferable because of the disadvantages such as the decomposition of the adhesive material layer. From this viewpoint, it is preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70 to 180°C, more preferably 75°C or higher or 150°C or lower, and more preferably It becomes 80 degreeC or more or 120 degreeC or less. Accordingly, it is more preferable to heat the adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70 to 150°C, or 70 to 120°C, and more preferably 75 to 150°C, or 75 to 120°C. 120°C, preferably 80 to 150°C, or 80 to 120°C. As a method of heating the adhesive sheet laminate, for example, a method of heating the adhesive sheet laminate between upper and lower heating plates equipped with a heating body such as an electric heater inside and heating from the upper and lower sides, or a method of directly sandwiching the adhesive sheet laminate The method of holding, the method of using a heating roller, the method of immersing it in hot water, etc. However, it is not limited to these methods. (Forming and Cooling Step) In this step, it is preferable to start the forming of the adhesive sheet laminate in a state where the surface temperature of the coating portion I is heated to 70 to 180° C. as described above. That is, it is preferable to shape|mold directly the adhesive sheet laminated body of the state which laminated|stacked the adhesive material layer and the coating part I integrally. Thereby, the adhesive material layer can be formed through the covering portion I at the same time as the covering portion I is formed. In this step, cooling may be performed after molding the heated adhesive sheet laminate, or cooling may be performed simultaneously with molding. For example, by pressing with a cooled mold, forming and cooling can be performed at the same time and finished at the same time. Thereby, the present manufacturing method 2 can be continuously implemented as described below. As the molding method, the molding method is not particularly limited as long as the pressure-sensitive adhesive sheet laminate can be integrally formed with a concavo-convex shape. For example, press forming, vacuum forming, air pressure forming, forming by rolls (roll forming), compression forming, forming by lamination, etc. are mentioned. Among them, press forming is particularly preferred from the viewpoint of formability and workability. When molding is performed using a mold, the material of the mold is not particularly limited. For example, resin-based materials such as polysiloxane and fluororesin, metal-based materials such as stainless steel and aluminum, and the like can be mentioned. Among them, since high-precision formability is required for the concavo-convex forming of the adherend, a metal-based mold capable of controlling the temperature during forming is particularly preferred. As the cooling method of the mold, a conventional cooling method can be used. For example, water cooling or a cooling method using compressed air is exemplified. For the mold, for example, as shown in FIG. 2, a specific concave-convex shape is preliminarily arranged on the inner wall surface of at least one of the open and closed pair of molds, for example, provided with the surface of the adherend of the adhesive layer. The concavo-convex shape conforming to the concave portion, convex portion, or concave-convex portion, and the above concave-convex shape can be transferred to the adhesive sheet by subjecting the adhesive sheet laminate to pressure forming, vacuum forming, air pressure forming or roll forming using the mold The material is laminated and shaped. As mentioned above, it is preferable to start shaping|molding in the state where the surface temperature of the said coating part I is 70-180 degreeC. When the surface temperature of the covering portion I is 70° C. or higher, the adhesive material layer is sufficiently softened and the covering portion I can be sufficiently deformed. It is preferable because of the disadvantages such as decomposition of the adhesive material layer caused by heat. Therefore, it is preferable to start molding in a state where the surface temperature of the coating portion I is 70 to 180°C, more preferably 75°C or higher or 150°C or lower, and still more preferably 80°C or higher or 120°C ℃ or lower. On the other hand, in this step, it is preferable to complete the molding in a state where the surface temperature of the coating portion I is less than 60°C. For example, in the case of press molding, it is preferable to open the mold in a state where the surface temperature does not reach 60°C. Here, "finishing the molding" means ending the application of the molding pressure to the adhesive sheet laminate, and in the case of mold molding, it means opening the mold. If the surface temperature of the covering portion I is less than 60° C., deformation when the molded body is taken out after molding is suppressed, or warping due to thermal shrinkage of the covering portion I can be suppressed, which is preferable. From this point of view, it is preferable to finish the molding in a state where the surface temperature of the coating portion I is less than 60°C, and it is preferable to finish the molding in a state where the surface temperature is 0°C or higher or 50°C or lower, and among them The molding is completed in a state of 10°C or higher or 40°C or lower. Although there are repetitions, in the present manufacturing method 2, the mold may be press-molded and cooled after the mold is opened, or the mold may be cooled in advance, and the cooling may be performed simultaneously with the press-molding. If the mold is cooled in advance in this way, and the cooling is performed simultaneously with the press molding, the molding and cooling can be completed at the same time. Thereby, the shaped adhesive sheet laminate can be conveyed to the next step immediately after the completion of forming and cooling, so that the shaped adhesive sheet laminate can be continuously produced. In the case of cooling at the same time as the molding of the mold, the surface temperature of the mold is preferably less than 60°C. If the surface temperature of the mold does not reach 60°C, the shape of the adhesive sheet laminate can be fixed in a short time, the obtained molded body can be obtained with good precision, and warpage accompanying thermal shrinkage during cooling after molding can be suppressed, It is better from this point of view. Therefore, the surface temperature of the mold is preferably lower than 60°C, more preferably 0°C or higher or 50°C or lower, and more preferably 10°C or higher or 40°C or lower. Moreover, 10-100 degreeC is preferable, and 20 degreeC or more or 90 degreeC or less is further more preferable among the difference of the surface temperature of the coating part I at the time of shaping|molding start and completion|finish of shaping|molding. Since the difference in the surface temperature of the coating portion I is 10 to 100° C., for example, when the uneven shape is transferred to the pressure-sensitive adhesive sheet layered body for shaping, the pressure-sensitive adhesive sheet can be shaped immediately after completion of shaping and cooling. Since the laminated body is conveyed to the next step, the shaped pressure-sensitive adhesive sheet laminated body can be continuously produced. In addition, the conditions of press-molding, such as press pressure and press time, are not specifically limited, What is necessary is just to adjust suitably according to the size and shape to be molded, the material to be used, and the like. (Others) The shaped pressure-sensitive adhesive sheet laminate obtained in the above-mentioned forming and cooling steps can be directly wound up, heat-treated, or cut into a specific size and shape. At the time of cutting, the method of cutting using a Thomson blade, a rotary cutter, etc. is mentioned, for example. In the present manufacturing method 2, it is preferable to continuously manufacture the shaped pressure-sensitive adhesive sheet laminate. For example, the adhesive sheet laminate may be conveyed to a heating unit such as a heater, and the conveyance may be stopped for a predetermined time in the heating unit to heat, or the heated adhesive sheet laminate may be conveyed to molding after being heated while conveying. A unit, such as a forming die, in the forming unit, for example, pressurized by a cooled die, cooled at the same time as forming, and then transported to the next unit as necessary to continuously manufacture a shaped adhesive sheet Laminated body. <Application> Here, an example of the utilization application of this shaping|molding adhesive sheet laminated body 1 is demonstrated. In recent years, with the generalization of mobile phones, smart phones, tablet terminals, etc., there have been many cases of damage to the image display portion due to user errors, such as dropping them. Especially when the image display device is of the touch panel type, not only does it become difficult to observe the display due to damage, but also the touch panel operation itself cannot be performed due to physical obstacles or water infiltration, or it becomes the cause of failure. . Therefore, there is a case in which maintenance, ie, repair, is performed only by replacing the image display unit. In the maintenance of the image display device, the adhesive sheet is also used when installing a new image display part. Generally, in many cases, the repair operator performs manual work, and the repair operator must be skilled. That is, if an unskilled person is not in use, when the image display part is mounted via an adhesive sheet, air may enter the inside, or the adhesive may be pushed out. On the other hand, when the present shaping adhesive sheet laminate 1 is used, since it is possible to preliminarily provide a highly precise step shape, etc., for example, the adhesive layer is preliminarily provided with a shape corresponding to the model of the image display device. The level difference shape can greatly simplify the maintenance operation, and it can be carried out without the need for skilled repair operators. As described above, the adhesive sheet laminate of the present invention can be usefully used for maintenance of image display devices. <Description of Statements> In this specification, when it is expressed as "X to Y" (X and Y are arbitrary numbers), unless otherwise specified, it means "more than X and less than Y", and also Include the meaning of "preferably larger than X" or "preferably smaller than Y". In addition, when it is expressed as "more than X" (X is an arbitrary number) or "less than Y" (Y is an arbitrary number), it also includes "preferably greater than X" or "preferably less than Y" meaning. In the present invention, the boundary between the sheet and the film is not determined, and it is not necessary to distinguish between the two in the context of the present invention, so in the present invention, the case of "film" also includes "sheet", The term "sheet" also includes "film".

That is, as shown in Fig. 5, the upper and lower molds for forming are convex molds with a length of 270 mm, a width of 170 mm, and a thickness of 40 mm, and the upper and lower molds are aluminum with a length of 270 mm, a width of 170 mm, and a thickness of 40 mm. flat.

According to the results in Table 1 and FIG. 4 and the test results so far, it was confirmed that, as shown in Examples 1-1 to 1-3, the elastic modulus E' (MB) by storage at 30°C was 5.0×10 ⁷ ~1.0×10 ¹⁰ Pa and storage elastic modulus E'(MA) at 100°C is 1.0×10 ⁶ ~2.0×10 ⁹ The coating part of Pa is laminated on the adhesive material layer and molded, so that the concave-convex shape can be shaped to the adhesive material layer with high precision. On the other hand, as shown in Comparative Example 1-1, when a biaxially stretched homopolymer PET film, which is generally widely used, is used as a release film, the storage elastic modulus of the covering portion exceeds 2.0× even in a high temperature range. 10 ⁹ Pa, even if thermoforming is performed, sufficient unevenness cannot be formed in the adhesive material layer.

Therefore, it was confirmed that by using the above-mentioned adhesive sheet laminate, the unevenness corresponding to the printing level difference of the image display device, which becomes the adherend, can be accurately formed, and there is no gap between the adherend and the adherend. In addition, even in the adherend in which the printed part is designed with a narrow edge, the adhesive material can be well adhered without overflowing, and the shaped adhesive sheet laminate for image display devices can be well adhered. In addition, with regard to the peeling force, the heating and cooling conditions when measuring the peeling force F(D), that is, the conditions of heating at 100° C. for 5 minutes and then naturally cooling to 30° C. are the conditions for producing the shaped pressure-sensitive adhesive sheet laminate. Typical heating and cooling conditions. Since the absolute values of the difference between the peeling force F(C) and the peeling force F(D) in the above-mentioned examples were all 0.1 N/cm or less, it was confirmed that the covering parts 1-A to 1- in the shaping adhesive sheet laminate were The peeling force of D is the same as the peeling force of the covering parts 1-A to 1-D in the adhesive sheet laminate.

The measurement was performed under the conditions of a measurement temperature range of -50°C to 150°C, a frequency of 1 Hz, and a temperature increase rate of 3°C/min. In the obtained data, the value of storage elastic modulus at 100°C is set as G'(SA), the value of loss elastic modulus is set as G''(SA), and the value of storage elastic modulus at 30°C is set as G''(SA).

In addition, even in the adherend in which the printed part is designed with a narrow edge, the adhesive material can be well adhered without overflowing, and the shaped adhesive sheet laminate for image display devices can be well adhered. In addition, with regard to the peeling force, the heating and cooling conditions when measuring the peeling force F(D), that is, the conditions of heating at 100° C. for 5 minutes and then naturally cooling to 30° C. are the conditions for producing the shaped pressure-sensitive adhesive sheet laminate. Typical heating and cooling conditions. Since the absolute values of the difference between the peeling force F(C) and the peeling force F(D) in the above-mentioned examples were all 0.1 N/cm or less, it was confirmed that the peeling force hardly changed before and after heating.

After biaxial stretching, heat treatment was performed at 185° C. for 3 seconds, followed by relaxation treatment of 6.4% in the width direction to obtain a polyester film with a thickness of 50 μm. The evaluation results are shown in Table 4 below. [Example 4-2], [Example 4-3] A polyester film was obtained in the same manner as in Example 4-1 except that the conditions shown in the following Table 4 were changed. The evaluation results are shown in Table 4 below. [Example 4-4] The above-mentioned polyesters 4-A and 4-C were mixed in proportions of 86% by weight and 14% by weight, respectively, as raw materials for the surface layer, so that polyesters 4-B and 4 The raw materials of -A mixed in the proportions of 45% by weight and 55% by weight, respectively, were used as the raw materials for the intermediate layer. Two kinds of amorphous sheets of 3-layer laminates (surface layer/intermediate layer/surface layer) were obtained by melt extrusion by different melt extruders, respectively. Next, an unaligned sheet is obtained by co-extruding the sheet onto a cooled casting drum and allowing it to cool and solidify. Then, after extending 3.4 times in the machine direction (MD) at 82°C, the preheating step was further carried out in the drawing machine, and then extending 3.9 times in the direction perpendicular to the machine direction (width direction, TD) at 110°C. After biaxial stretching, heat treatment was performed at 210° C. for 3 seconds, followed by relaxation treatment of 2.4% in the width direction to obtain a polyester film with a thickness of 50 μm. The evaluation results are shown in Table 4 below.

(1) Storage Elastic Modulus (E') For the films obtained in Example Group 4, a sample of 30 mm in the longitudinal direction x 5 mm in the width direction was collected so that the longitudinal direction became the machine direction. Next, using a dynamic viscoelasticity device (“DVA-220” manufactured by IT Meter and Control Co., Ltd.), the sample was clamped and fixed by clamps with an interval of 20 mm, and the sample was heated at a rate of 10°C/min from room temperature.
