Description

Coating film

The present invention is about forming images such as personal computers, mobile terminals (PDAs (personal digital assistants)), game consoles, televisions (TV), car navigation systems, touch panels, handwriting boards, etc. A shaped adhesive sheet laminate that can be suitably used in a display device, and an adhesive sheet laminate suitable for forming a shaped adhesive sheet laminate.

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 image display devices"). In recent years, the surface protection panels of image display devices using touch panels such as smartphones or tablet terminals use tempered glass while using plastic materials such as acrylic resin sheets or polycarbonate sheets. The visibility openings of the surface protection panels The peripheral part outside the face is printed in black. In addition, in the touch panel, a plastic film sensor is used together with the glass sensor, or a component called TOL that integrates the function of the touch panel and the surface protection panel is used. , Or use a component called table-embedded or in-cell type 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, it is usually used to fill the gaps between the constituent members of the image display device with a transparent resin such as a liquid adhesive, a thermoplastic adhesive sheet, and an adhesive sheet.的结构。 The structure. In addition, in the field of image display devices centered on mobile phones or mobile terminals, in addition to thinning and high-precision, the diversification of designs continues to develop. Previously, black was printed on the periphery of the surface protection panel. However, with the diversification of designs, the frame-shaped concealed part began to be formed in colors other than black. When the concealed part is formed in a color other than black, since the concealment is low, the height of the concealed part, that is, the printed part, tends to be higher than that of black. Therefore, it is required to fill in the corners of the adhesive sheet used for bonding the constituent members provided with such a printing section to follow a large printing step. Therefore, since the previous, various methods have been proposed to fill the printing step. For example, in Patent Document 1, even if the adhered surface of the adhered sheet has a step formed by printing or the like, it can be adhered to the adhered surface without gaps in a double-sided manner for a new image display device. Adhesive sheet, and discloses a double-sided adhesive sheet for image display devices, which is used to combine any two constituent members for image display devices selected from surface protection panels, touch panels, and image display panels The double-sided adhesive sheet to which the adherend is attached, and at least one adherend has a step on the adhered surface of the double-sided adhesive sheet to be adhered, and the double-sided adhesive sheet is an adhesive that adheres to the adhered surface The shape of the mating surface is formed along the shape of the surface to be adhered. In addition, in Patent Document 2, a method for manufacturing a double-sided adhesive sheet for bonding any two adherends selected from a surface protection panel, a touch panel, and an image display panel, discloses an image The method for manufacturing a double-sided adhesive sheet for a display device is 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 surface shape of the mating surface has the same concave and convex shape. Prior art literature Patent literature 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 or mobile terminals, thinner walls and higher precision have been further required. Adhesive sheets are also required to be able to fill the unevenness of the surface of the adherend such as printing steps with high accuracy, and there is no situation where the adhesive is exposed to the outside. As a countermeasure to this requirement, as disclosed in the above-mentioned previous patent documents, it has been studied to form the surface shape of the adhesive sheet in advance with the surface shape of the adherend. In addition, in order to form the surface shape of the adhesive sheet in advance with the surface shape of the adherend as described above, the following method is assumed: an adhesive sheet laminate formed by laminating a release sheet on both sides of the adhesive sheet The body is press-molded to form a concave-convex shape that matches the concave-convex part on the surface of the adherend. However, an attempt was made to use a conventional release sheet laminated on both sides of the adhesive sheet to form an adhesive sheet laminate, and the above method was actually implemented. As a result, the following problem became clear: it is difficult to form and adhere to the surface of the adhesive sheet with high precision. The concave-convex shape of the body surface conforms to the concave-convex part. Therefore, the present invention relates to an adhesive sheet laminate having an adhesive material layer and a covering part laminated on one side of the adhesive material layer in a peelable manner, and proposes an adhesive sheet laminate that can be formed on the surface of the adhesive material layer with high precision A new adhesive sheet laminate having a concave-convex shape corresponding to the uneven portion on the surface of the adherend, and a shaped adhesive sheet laminate using the adhesive sheet laminate. [Technical Means to Solve the Problem] The present invention proposes an adhesive sheet laminate, which is an adhesive sheet laminate having an adhesive layer and a covering portion I laminated on one side of the adhesive layer in a peelable manner Body, characterized in that: the storage elastic modulus E'(MA) of the covered part I at 100°C is 1.0×10 ⁶ to 2.0×10 ⁹ Pa, and the storage elastic modulus of the covered part I at 30°C E'(MB) is 5.0×10 ⁷ to 1.0×10 ¹⁰ Pa. In addition, as a shaped adhesive sheet laminate using the above adhesive sheet laminate, the present invention proposes a shaped adhesive sheet laminate, wherein the adhesive layer has recesses, protrusions, or recesses on one of the front and back surfaces. Concavo-convex parts (referred to as "concavo-convex parts on the surface of the adhesive material layer"), and the covering part I is in close contact with one of the front and back surfaces of the adhesive material layer, and is provided with concavities, convexities or concavities and convexities on one of the front and back surfaces Part (referred to as "coating part surface concavity and convexity"), and on the other side of the front and back side opposite to the one side of the front and back, the surface of the front and back is provided with concavities and convexities corresponding to the concavities and convexities of the surface of the adhesive layer Convex, concave, or convex-concave portion (referred to as "concave and concave portion on the back of the covered portion"). [Effects of the Invention] According to the adhesive sheet laminate proposed in the present invention, for example, by heating the above adhesive sheet laminate, pressing the mold against the covering portion I for molding, the surface of the adhesive sheet can be made high. Accurately form the uneven shape that matches the unevenness of the surface of the adherend. In addition, since the covering portion I can maintain the shape retention in a normal state, it is easier to handle. Not only that, but 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 provided by the present invention is provided with an adhesive sheet surface concavity and convexity on one of the front and back sides of the adhesive layer, and the covering portion I is in close contact with one of the front and back sides of the adhesive layer On the front surface, one side surface of the front surface and the back surface is provided with concave and convex portions on the surface of the covering portion, and the other side surface of the front surface and the back surface opposite to the one side of the front and back surface is provided with convex and concave portions on the back surface of the covering portion. As described above, the shaped adhesive sheet laminate provided by the present invention is provided with the covering portion I in close contact with one of the front and back surfaces of the adhesive layer without gaps, and the covering portion I is peelable. The structure is laminated on one of the front and back surfaces of the above-mentioned adhesive material layer. Therefore, it can prevent dust and the like from adhering to the surface of the adhesive material layer and the adhesive force is reduced, and it can also prevent the formation on the front side of the above-mentioned adhesive material layer. The shape of the surface unevenness of the adhesive material layer formed by the side surface of the back surface absorbs moisture in the air and disintegrates, or dust or the like adheres to the surface and the adhesive force decreases.

Hereinafter, an example of the embodiment of the present invention will be described. However, the present invention is not limited by the following embodiments. [This adhesive sheet laminate] The adhesive sheet laminate of an example of the embodiment of the present invention (referred to as "the present adhesive sheet laminate") is shown in FIG. An adhesive sheet laminate of a covering part I formed on one side of the adhesive layer, and a covering part II formed by releasably layering on the other side of the front and back faces of the adhesive layer. Here, the covering portion II is arbitrary, and a configuration in which the covering portion II is not laminated may be adopted. ＜Adhesive layer＞ The adhesive layer of the adhesive sheet laminate can function as a double-sided adhesive sheet when the covering part I and the covering part II are peeled off, and it has a hot-melt property that softens or melts when heated. Can. The adhesive layer preferably has a loss tangent tanδ (SA) of 1.0 or more at 100°C. Furthermore, it is preferable that the loss tangent tanδ (SB) at 30°C is less than 1.0. Here, the loss tangent tanδ means the ratio of the loss elastic modulus G" to the storage elastic modulus G'(G"/G'). Since the temperature at the time of thermoforming 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 it can be maintained on the surface of the adhesive material layer to accurately form the unevenness on the surface of the adherend. The state of the concave-convex shape. Generally, polymer materials have both viscous and elastic properties, and the loss tangent tanδ is 1.0 or more, and the greater the value, the stronger the viscous properties. On the other hand, the loss tangent tanδ does not reach 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 point of view, the loss tangent tanδ (SA) of the adhesive layer at 100°C is preferably 1.0 or more, more preferably 1.5 or more or 30 or less, and more preferably 3.0 or more or 20 or less.

Here, the loss tangent tanδ (SA) of the adhesive layer at 100°C and the loss tangent tanδ (SB) at 30°C can be adjusted by adjusting the composition or gel fraction and weight average of the composition constituting the adhesive layer The molecular weight etc. are adjusted to the above-mentioned range. Furthermore, the storage elastic modulus G'(SA) of the adhesive material layer at 100°C is preferably less than 1.0×10⁴ Pa. In addition, the storage elastic modulus G'(SB) of the adhesive material layer at 30°C is preferably 1.0×10⁴ Pa or more. If the storage elastic modulus G'(SA) of the adhesive layer at 100℃ does not reach 1.0×10⁴ Pa, sufficient formability can be obtained, so it is better. On the other hand, if the storage elastic modulus G'(SB) of the adhesive layer at 30°C is 1.0×10⁴ Pa or more is preferable from the viewpoint of shape stability after forming. From this point of view, the storage elastic modulus G'(SA) of the adhesive layer at 100°C is preferably less than 1.0×10⁴ Pa, of which 5.0×10 is more preferable¹ Pa or more or 5.0×10³ Pa or less, of which 1.0×10 is more preferred² Pa or above or 1.0×10³ Pa below. Accordingly, the storage elastic modulus G'(SA) of the adhesive layer at 100℃ is preferably 5.0×10¹ Pa above and less than 1.0×10⁴ Pa, or 5.0×10¹ Pa or more and 5.0×10³ Pa or less, of which 1.0×10 is more preferred² Pa above and less than 1.0×10⁴ Pa, or 1.0×10² Pa or more and 5.0×10³ Pa below, best 1.0×10² Pa or more and 1.0×10³ Pa below. Also, from this viewpoint, the storage elastic modulus G'(SB) of the adhesive layer at 30°C is preferably 1.0×10⁴ Pa or more, of which 2.0×10 is more preferable⁴ Pa or above or 1.0×10⁷ Pa or less, of which 5.0×10 is more preferable⁴ Pa or above or 1.0×10⁶ Pa below. Furthermore, according to this, the storage elastic modulus G'(SB) of the adhesive material layer at 30°C is more preferably 1.0×10⁴ Pa or more and 1.0×10⁷ Pa or less, or 1.0×10⁴ Pa or more and 1.0×10⁶ Pa below, more preferably 2.0×10⁴ Pa or more and 1.0×10⁷ Pa or less, or 2.0×10⁴ Pa or more and 1.0×10⁶ Pa below, best 5.0×10⁴ Pa or more and 1.0×10⁶ Pa below. Here, the storage elastic modulus G'(SA) of the adhesive layer at 100°C and the storage elastic modulus G'(SB) of the adhesive layer at 30°C can be adjusted by adjusting the composition of the adhesive layer The components, gel fraction, weight average molecular weight, etc. are adjusted to the aforementioned ranges. The temperature at which the loss tangent tanδ of the adhesive material layer becomes 1.0 is preferably 50 to 150°C, more preferably 60°C or higher or 130°C or lower, and still more preferably 70°C or higher or 110°C or lower. If the temperature at which the loss tangent tanδ of the adhesive material layer becomes 1.0 is 50 to 150°C, the present adhesive sheet laminate can be preliminarily heated to 50 to 150°C for mold forming. The glass transition temperature (Tg) of the base resin of the adhesive material layer is preferably -50 to 40°C, and 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 refers to 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 adhesiveness can be imparted to the adhesive material layer, and further, the temperature at which the loss tangent tanδ of the adhesive material layer becomes 1.0 can be adjusted to 50-150°C. As the material of the adhesive layer, as long as it is a material that can be prepared with a specific viscoelastic behavior, a previously known adhesive sheet can be used. For example: 1) Use (meth)acrylate polymer (in the meaning including copolymer, hereinafter referred to as "acrylate (co)polymer") as the base resin, and mix the crosslinking unit in it Mixing cross-linking initiators or reaction catalysts as needed to make the adhesive sheet formed by the cross-linking reaction; or 2) Using butadiene or isoprene-based copolymers as the base resin, blending crosslinking monomers, blending crosslinking initiators or reaction catalysts as necessary, etc., are formed by crosslinking reaction.

In addition to the above-mentioned viscoelastic properties or thermal properties of the physical properties of the adhesive layer itself, it is not an essential problem in the present invention.

When properties such as electrical properties and low refractive index are required, it is preferable to use the butadiene or isoprene-based copolymer of 2) as the base resin. When properties such as heat resistance and rubber elasticity in a wide temperature range are required, it is preferable to use the polysiloxane copolymer of 3) as the base resin. When properties such as releasability are required, it is preferable to use the polyurethane-based polymer of 4) as the base resin. As an example of the above-mentioned adhesive layer, a resin composition containing a (meth)acrylic copolymer (a) as a base resin, a crosslinking agent (b), and a photopolymerization initiator (c) can be exemplified The adhesive sheet. In this case, the above-mentioned viscoelastic properties must be satisfied in an uncrosslinked state, that is, before forming a three-dimensionally crosslinked network structure. 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 the molecular chains constituting the adhesive material layer can be suppressed to an appropriate range, so it can be formed into a shaped adhesive sheet laminate. fluidity. From this point of view, the gel fraction of the adhesive 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 material layer is not limited, and it may be 0%. Furthermore, the gel fraction of the above-mentioned adhesive material layer is not limited to those containing (meth)acrylic copolymer (a), crosslinking agent (b), and photopolymerization initiator (c) as the base resin.

The glass transition temperature of the copolymer constituting the main chain component of the acrylic copolymer (A1) is preferably -70 to 0°C. At this time, the so-called 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).

(Photopolymerization initiator (c)) When crosslinking the acrylate polymer, if appropriate, add a crosslinking initiator (peroxidation initiator, photopolymerization initiator) or reaction catalyst (tertiary amine compound, quaternary ammonium compound, lauric acid Tin compounds, etc.) are more effective. In the case of crosslinking by ultraviolet irradiation, it is preferable to prepare a photopolymerization initiator (c). The photopolymerization initiator (c) is roughly divided into two categories according to the free radical generation mechanism, which can be roughly divided into: cleavage-type photopolymerization initiators that can cleavage and decompose the single bond of the photopolymerizable initiator itself to generate free radicals ; And the light-excited initiator and the hydrogen donor in the system to form an excited complex, which can transfer the hydrogen of the hydrogen donor to the hydrogen abstraction type photopolymerization initiator. The cleavage-type photopolymerization initiator among these decomposes when generating free radicals by light irradiation to become other compounds, and once it is excited, it 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 crosslinked by light irradiation, the light reacts The reactive photopolymerizable initiator remains in the adhesive composition as an unreacted residue, which may cause unexpected changes over time of the adhesive sheet or promote crosslinking, which is preferable. In addition, with regard to the unique coloration of the photopolymerizable initiator, it is also preferable to appropriately select the one that becomes a reaction decomposition product, which disappears the absorption in the visible light region and decolorizes. On the other hand, the hydrogen abstraction type photopolymerization initiator does not generate decomposition products such as the cleavage type photopolymerization initiator during the reaction that generates free radicals irradiated by active energy rays such as ultraviolet rays, so it is difficult to complete the reaction. It becomes a volatile component, which can reduce the damage to the adherend. As the above-mentioned cleavage-type photopolymerization initiator, for example, 2,2-dimethoxy-1,2-diphenylethane-1-one, 1-hydroxycyclohexylphenyl ketone, 2-hydroxy- 2-Methyl-1-phenyl-propane-1-one, 1-(4-(2-hydroxyethoxy)phenyl)-2-hydroxy-2-methyl-1-propane-1-one, 2-hydroxy-1-[4-{4-(2-hydroxy-2-methyl-propanyl)benzyl}phenyl]-2-methyl-propan-1-one, oligo(2-hydroxyl -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olinyl)phenyl]-1-butanone, bis(2,4,6-trimethylbenzene) (Formyl)-phenylphosphine oxide, 2,4,6-trimethylbenzyldiphenylphosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenyl oxide Phosphine, bis(2,6-dimethoxybenzyl) 2,4,4-trimethylpentyl phosphine oxide, or derivatives thereof. Among them, bis(2,4,6-trimethylbenzyl)-phenyl is preferred in terms of turning into a decomposed product and decoloring by the cleavage-type photopolymerizable initiator after the reaction. Phosphine oxide, 2,4,6-trimethylbenzyldiphenyl phosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenyl phosphine oxide, bis(2,6 -Dimethoxybenzyl) 2,4,4-trimethylpentyl phosphine oxide and other phosphine oxide-based photoinitiators. Furthermore, in terms of compatibility with acrylic copolymers containing graft copolymers having macromonomers as branched components, it is preferable to use 2,4,6-trimethylbenzyldiphenyl Phosphine oxide, (2,4,6-trimethylbenzyl)ethoxyphenyl phosphine oxide, bis(2,6-dimethoxybenzyl)2,4,4-trimethyl Pentyl phosphine oxide and the like are used as a photopolymerization initiator. The content of the photopolymerization initiator is not particularly limited. For example, with respect to 100 parts by mass of the (meth)acrylic copolymer, it is 0.1-10 parts by mass, particularly preferably 0.2 parts by mass or more or 5 parts by mass, and particularly preferably 0.5 parts by mass or more or 3 parts by mass. Contained in the following proportions. However, in terms of balance with other elements, this range can also be exceeded. The photopolymerization initiator can be used singly or in combination of two or more kinds. In addition to the above ingredients, pigments such as pigments or dyes with near-infrared absorption characteristics, adhesion imparting agents, antioxidants, anti-aging agents, moisture absorbents, ultraviolet absorbers, silane coupling agents, natural products or synthetic materials can also be appropriately formulated as needed. Various additives such as resins, glass fibers or glass beads. (Layer structure and thickness of adhesive layer) In addition to a single layer, the adhesive layer can also be multiple layers such as two layers or three layers. In addition, the adhesive material layer may also have a substrate layer (a layer without adhesiveness) as a core layer, and a layer containing an adhesive material is laminated on both sides of the substrate layer. In the case of such a structure, it is preferable that the base material layer as the core layer has a material or characteristic that enables the heat-molding of the adhesive sheet laminate. Furthermore, it is preferable that the adhesive material layer other than the substrate layer has loss tangent tanδ (SA), loss tangent tanδ (SB), storage elastic modulus G'(SA), and storage elastic modulus G'(SB). The above characteristics. The thickness of the adhesive layer is not particularly limited. Among them, the range of 20 μm to 500 μm is preferable. If it is in this range, for example, if it is a thinner adhesive layer with a thickness of 20 μm, it is possible to provide an adhesive sheet with excellent print step followability. In addition, if it is a thicker adhesive material layer such as a thickness of 500 μm, it is possible to prevent the adhesive material from overflowing at the time of lamination by forming an amount equivalent to the printing step difference in advance. Therefore, the thickness of the adhesive material layer is preferably 20 μm to 500 μm, wherein more preferably 30 μm or more or 300 μm or less, and more preferably 50 μm or more or 200 μm or less. ＜Coated part I＞ The adhesive sheet laminate as shown in FIG. 1 is provided with a covering portion I as shown in FIG. become. The storage elastic modulus E'(MA) of the covering part I at 100°C is preferably 1.0×10⁶ ～2.0×10⁹ Pa. Since the temperature at the time of heating and forming the laminated body of the adhesive sheet is usually 70～120℃, the storage elastic modulus E'(MA) at 100℃ is 1.0×10⁶ ～2.0×10⁹ Pa, in the temperature range where the adhesive composition is plasticized to flow, the covering part I can fully follow the uneven shape and deform. Not only that, but also the adhesive material layer squeezed by the covering part I during molding The surface is shaped with high precision, for example, to avoid rounding the corners to form the required concave and convex shapes. Previously, as a release film laminated on an adhesive sheet, materials with a higher storage elastic modulus, in other words, "harder" materials were often used. The reason is that the required characteristics of the release film are mainly to protect the adhesive layer and release properties. However, according to the research of the inventors and others, it was found that in the new application of thermoforming in the state of laminating the release film on the adhesive sheet, when the new problem of thermoformability is required, the previous separation The above-mentioned physical properties of the type film cannot meet the requirements. Therefore, the phenomenon that occurs during thermoforming or the characteristics of the adhesive layer have been investigated in detail. As a result, it has been found that setting the characteristics of release film different from the conventionally used release film is a new problem for solving thermoformability. In terms of favorable. It is found that the above-mentioned problems can be solved by controlling the storage elastic modulus at a specific temperature to a specific range. From this point of view, the storage elastic modulus E'(MA) of the covering part I at 100°C is preferably 1.0×10⁶ ～2.0×10⁹ Pa, of which 5.0×10 is more preferable⁶ Pa or above or 1.0×10⁹ Pa or less, of which 1.0×10 is more preferred⁷ Pa or more or 5.0×10⁸ Pa below.

In addition, the storage elastic modulus E'(MB) of the covering part I at 30°C is preferably 5.0×10⁷ ~1.0×10¹⁰ Pa. If the storage elastic modulus E'(MB) of the covered part I at 30℃ is 5.0×10⁷ ~1.0×10¹⁰ Pa can maintain shape retention under normal conditions, so it is easier to handle, such as easy to peel off. Not only that, but because it is not too hard, it can suppress the formation of unintended unevenness in the adhesive layer. From this point of view, the storage elastic modulus E'(MB) of the covering part I at 30°C is preferably 5.0×10⁷ ~1.0×10¹⁰ Pa, where 1.0×10 is more preferable⁸ Pa or above or 8.0×10⁹ Pa or less, of which 1.0×10 is more preferred⁹ Pa or more or 5.0×10⁹ Pa below. Accordingly, the storage elastic modulus E'(MB) of the covering part I at 30°C is more preferably 5.0×10⁷ ～8.0×10⁹ Pa, or 5.0×10⁷ ~5.0×10⁹ Pa, among them, 1.0×10 is more preferable⁸ Pa～1.0×10¹⁰ Pa, or 1.0×10⁸ Pa～8.0×10⁹ Pa, the best is 1.0×10⁹ ～8.0×10⁹ Pa, or 1.0×10⁹ ~5.0×10⁹ Pa. In order to adjust the storage elastic modulus of the coated part I at 30°C and 100°C to the above, for example, the type of base resin, copolymer resin composition, weight average molecular weight, glass transition temperature, crystallinity, etc. can be adjusted. The conditions of the material, and adjust the presence or absence of extension, the forming conditions, and adjust the extension conditions in the case of extension to adjust the manufacturing conditions.

(2)・・1.0×10³ ≦E'(MA)/G'(SA)≦1.0×10⁷ If the storage elastic modulus G'(SA) of the adhesive material layer at 100°C and the storage elastic modulus E'(MA) of the covering part I at 100°C satisfy the above relationship (2), then sufficient The formability is therefore better. From this viewpoint, E'(MA)/G'(SA) is preferably 1.0×10³ ~1.0×10⁷ , Of which 5.0×10 is particularly preferred³ Above or 5.0×10⁶ Below, 1.0×10 is particularly preferred⁴ Above or 1.0×10⁶ the following.

In order to adjust E'(MA) and G'(SA) to have the above-mentioned relationship, it is only necessary to adjust the characteristics of the adhesive layer or the coating portion I. The characteristics of the adhesive material layer can be achieved, for example, by adjusting the components, gel fraction, weight average molecular weight, etc. of the composition constituting the adhesive material layer.

As a configuration example of the coating portion I, a configuration example including a coating base layer and a release layer can be cited. With the single-area release layer on the covering base layer, the covering portion I can be constructed in such a way that it can be easily peeled off from the adhesive layer.

In addition, since the coating film can maintain shape retention under normal conditions, it is easier to handle. Not only that, but because it is not too hard, it can suppress the formation of unintended unevenness on the adhesive sheet. ＜Copolymerized polyester film＞ The copolymerized polyester film constituting the coating film may be a single-layer structure or a multi-layer structure.

In addition, as the glycol component, ethylene glycol is preferred. In addition to this, propylene glycol, trimethylene glycol, tetramethylene glycol, hexamethylene glycol, and 1,4-cyclohexane may be contained. One or more of well-known glycols, such as dimethanol, diethylene glycol, triethylene glycol, polyalkylene glycol, and neopentyl glycol, are used as the copolymerization component. Among them, it is more preferable to use phthalic acid and isophthalic acid as the dicarboxylic acid component, and 1,4-cyclohexanedimethanol, 1,4-butanediol, and diethylene glycol as the diol component.

On the other hand, by being 50 mol% or less, it not only has sufficient dimensional stability, but also can sufficiently suppress the generation of wrinkles during processing. The melting point of the copolymerized polyester film is preferably designed so as to be preferably 260°C or lower, more preferably 200 to 255°C. With the aforementioned melting point of 260°C or lower, in the heat treatment step after stretching, sufficient strength can be obtained even if the heat treatment is at a temperature lower than the melting point of the copolymerized polyester film. In terms of improving the workability of the film, it is more desirable to include particles in the copolymerized polyester film. Examples of particles include inorganic particles such as calcium carbonate, magnesium carbonate, calcium sulfate, barium sulfate, lithium phosphate, magnesium phosphate, calcium phosphate, lithium fluoride, alumina, silica, and kaolin; acrylic resins, guanamine resins, etc. Organic particles; Precipitated particles formed by granulating catalyst residuals, but they are not limited to these. The particle size of the 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 at the same time. In addition, various stabilizers, lubricants, antistatic agents, etc. can also 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 above-mentioned particles is less than 0.1 μm, the sliding properties of the film may become insufficient, and workability may decrease. On the other hand, when the average particle diameter of the 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 the content of the above particles is less than 0.01% by weight, the sliding properties of the film may become insufficient, and workability may decrease. On the other hand, when the content of the above-mentioned particles exceeds 0.3% by weight, the smoothness of the film surface may be impaired. The method of adding particles to the copolymerized polyester film is not particularly limited, and a known method can be adopted. For example, it can be added at any stage of the production of polyester, preferably at the stage of esterification, or at the stage after the end of the transesterification reaction before the start of the polycondensation reaction, as a slurry dispersed in ethylene glycol, etc. The polycondensation reaction is carried out. In addition, a method of blending a slurry of particles dispersed in ethylene glycol or water with polyester raw materials by using a kneading extruder with vent holes, or using a kneading extruder to mix the dried particles The method of blending with polyester raw materials, the method of precipitating particles in the polyester production step system, etc. are carried out. The limiting viscosity of the copolymerized polyester is usually 0.40 to 1.10 dl/g, preferably 0.45 to 0.90 dl/g, and more preferably 0.50 to 0.80 dl/g. If the ultimate viscosity is less than 0.40 dl/g, the mechanical strength of the film tends to become weaker. When the ultimate viscosity exceeds 1.10 dl/g, the melt viscosity becomes higher, which may cause excessive load on the extruder. situation. Next, although the manufacturing example of a copolymerized polyester film is demonstrated concretely, it is not limited at all by the following manufacturing example. Preferably, the following method is used: first, using the previously described copolymerized polyester raw material, the molten sheet extruded from the die is cooled and solidified by a cooling roll 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 it is preferable to adopt an electrostatic encryption bonding method and/or a liquid coating adhesion method. Then, it is preferable to extend the obtained unstretched sheet at least in a uniaxial direction, more preferably biaxially extending in a biaxial direction. For example, as biaxial stretching, in the case of successive biaxial stretching, the unstretched sheet is stretched in one direction along the machine direction by means of a roll or a stretcher in a stretch-and-spoke manner. The stretching temperature is usually 70-120°C, preferably 75-110°C, and the stretching ratio is usually 2.5-7.0 times, preferably 3.0-6.0 times. Second, extend in a direction perpendicular to the extension direction (mechanical 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 150-270° C. under stretching or relaxation within 30% to obtain a biaxially oriented film. In the above-mentioned biaxial stretching, a method of performing stretching in one direction in more than two stages can also be used. In this case, it is preferable to perform so that the stretching magnifications in the two directions finally fall into the above-mentioned ranges. In addition, with regard to the production of the copolymerized polyester film, simultaneous biaxial stretching can also be used. At the same time, biaxial stretching is a method of simultaneously extending and aligning the unstretched sheet in the machine direction and the width direction under a temperature-controlled state at 70-120°C, preferably 75-110°C. As the stretching magnification, it is preferably 4 to 50 times in terms of area magnification, more preferably 7 to 35 times, and still more preferably 10 to 25 times. Then, heat treatment is continued at a temperature of 150-250°C under stretching or relaxation within 30% to obtain a biaxially stretched film. Regarding the simultaneous two-axis extension device using the above-mentioned extension method, a spiral method, a pantograph method, a linear drive method, and the like, which have been known from the past, can be used. (Coating layer) In this coating film, it is important to provide a coating layer on at least one side of the copolymerized polyester film. The coating layer is not particularly limited, and specific examples include a release layer, an antistatic layer, an oligomer sealing layer, an easy-adhesive layer, an undercoat layer, and the like. Among them, the release layer is more preferable in terms of manufacturing an adhesive sheet laminate formed by laminating with an adhesive sheet. In addition, two or more types of the above-mentioned functional layers may be combined. 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 may include a curable silicone resin, a fluorine-based resin, a polyolefin resin, etc. Among them, a curable silicone resin is preferred. It can be a curing type silicone resin, or a type with a curing type silicone resin as the main component. Within the scope that does not impair the spirit of the present invention, it can also be used by combining with urethane resin, ring Modified silicone type obtained by graft polymerization of organic resins such as oxygen resin and alkyd resin. As the type of curing type silicone resin, any curing reaction type such as addition molding, condensation type, ultraviolet curing type, electron beam curing type, and 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 Industry 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- manufactured by Momentive Performance Materials A2775, XS56-A2982, UV9430, TPR6600, TPR6604, TPR6605; SRX357, SRX211, SD7220, SD7292, LTC750A, LTC760A, LTC303E, SP7259, BY24-468C, SP7248S, BY24-452, DKQ3- manufactured by Dow Corning Toray Co., Ltd. 202, DKQ3-203, DKQ3-204, DKQ3-205, DKQ3-210, etc. Furthermore, in order to adjust the peelability etc. of a release layer, you may use a peeling control agent together. The curing conditions when forming the release layer on the copolymerized polyester film are not particularly limited. When the release layer is provided by off-line coating, it is usually suitable to heat treatment at 120-200°C for 3-40 seconds, preferably at 100-180°C for 3-40 seconds. Furthermore, if necessary, active energy ray irradiation such as heat treatment and ultraviolet irradiation may be used in combination. Furthermore, as an energy source for curing by active energy ray irradiation, a device and an energy source known from the past can be used. The coating amount of the release layer (after drying) is usually 0.005～1 g/m in terms of coatability² The range is preferably 0.005～0.5 g/m² The range is more preferably 0.01～0.2 g/m² The scope. The coating amount (after drying) is less than 0.005 g/m² In this case, there is a lack of stability in terms of coatability, and it is difficult to obtain a uniform coating film. On the other hand, at more than 1 g/m² In the case of thick coating, the adhesiveness and curability of the coating film of the release layer itself may decrease. As a method of providing a release layer on a copolymerized polyester film, conventionally known methods such as reverse gravure coating, direct gravure coating, roll coating, die nozzle coating, bar coating, curtain coating, etc. can be used. The coating method. Regarding the coating method, there are examples in "Coating Method" (Maki Bookstore Harasaki Yuji, published in 1979). In addition, in order to provide a coating layer on the copolymerized polyester film, surface treatments such as corona treatment, plasma treatment, and ultraviolet irradiation treatment may be applied to it in advance. (Coating film) The thickness of the 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 thickness is less than 9 μm, the tension of the film may become insufficient, which may cause abnormalities such as wrinkles during slitting. On the other hand, if it exceeds 250 μm, the followability to molded products having a curved shape may become insufficient, for example. The storage elastic modulus E'of this coating film at 100℃ is 1.5×10⁹ Pa or less, preferably 1.0×10⁹ Pa below. By the above storage elastic modulus E'is 1.5×10⁹ Pa or less, when it is laminated with the 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°C satisfy the above range, it can be satisfied by adjusting the type and content of the copolymerized component contained in the copolymerized polyester film. On the other hand, the lower limit is not particularly limited, but 1.0×10 is preferred.⁷ Pa or more, more preferably 1.0×10⁸ Pa or more. The shrinkage rate of the coating film after heating at 120°C for 5 minutes is 3.0% or less, preferably 2.5% or less. The shrinkage rate is 3.0% or less, and it has sufficient dimensional stability. Therefore, when it is laminated with the adhesive sheet, a concave shape, a convex shape, or a concave-convex shape can be formed on the surface of the adhesive sheet. Furthermore, the generation of wrinkles during processing can be suppressed, so the wrinkles are not transferred to the adhesive sheet, and an adhesive sheet with sufficient appearance can be manufactured. 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, the lower limit is not particularly limited, but it is preferably 0.1% or more, and more preferably 0.5% or more. In addition, the shrinkage rate in the direction perpendicular to the machine direction (TD) after heating at 120°C for 5 minutes is preferably 1.0% or less, more preferably 0.8% or less. On the other hand, as the lower limit, it is preferably -1.0% or more, and more preferably -0.5% or more. From the viewpoint of preventing contamination caused by the adhesion of oligomers (cyclic trimers) to the mold during the forming process, the coating film is preferably heat-treated (180°C, 10 minutes). The amount of extraction on the surface of the layer is 1.0×10^-3 mg/cm² Below, more preferably 5.0×10^-4 mg/cm² the following. When the extraction amount of the above-mentioned oligomer exceeds this range, the contamination caused by the adhesion of the oligomer to the mold during the molding process may become serious. As an example, in the process of multiple continuous heating and forming, the deposit of precipitated oligomers promotes mold contamination, so it becomes important to control the amount of oligomers precipitated during heating. For the above reasons, the smaller the amount of the oligomer extracted, the better. [The manufacturing method of the adhesive sheet laminate] As an example of the manufacturing method of this adhesive sheet laminated body, the following method is mentioned, for example: The adhesive composition is sandwiched between two coating parts I or II, and the adhesive layer is formed using a laminator. Moreover, as another method, the method of apply|coating an adhesive composition to the coating part I or II to form an adhesive material layer is mentioned. However, it is not limited to this manufacturing method. As a method of applying the adhesive composition, for example, conventionally known coating methods such as reverse roll coating, gravure coating, bar coating, and knife coating can be cited. [This shaped adhesive sheet laminate] This adhesive sheet laminate can be used to produce a shaped adhesive sheet laminate 1 (referred to as "the present shaped adhesive sheet laminate 1") with uneven shapes formed on the surface of the adhesive layer in the following manner. As shown in FIG. 3, the shaped adhesive sheet laminate 1 can be made to have the following configuration: it is provided with an adhesive layer 2, laminated on one of the front and back of the adhesive layer 2 in a peelable manner The covering part I formed from the side, and the covering part II formed by being peelably laminated on the other side of the front and back of the adhesive layer 2, The adhesive layer 2 is provided with recesses, protrusions, or concavo-convex portions on one of the front and back surfaces 2A (referred to as "adhesive sheet surface concavities and convexities 2B"), and the other side surface 2C of the front and back surfaces is flat. The covering portion I is in close contact with one of the front and back side surfaces 2A of the above-mentioned adhesive sheet 2, and is provided with recesses, protrusions, or uneven portions (referred to as "covering portion surface unevenness 3B") on one of the front and back side surfaces 3A, In addition, the back surface of the sheet 3C is provided with convex portions, concave portions, or convex-concave portions (referred to as "protective sheet back surface convex-concave portions 3D") that conform to the above-mentioned concave-convex portions 2B on the surface of the adhesive sheet, in other words, form fitting concavities and convexities. The covering portion II includes a flat surface along the other side surface 2C of the front and back of the adhesive sheet 2. Furthermore, the other side surface 2C of the front and back side can be made into a flat surface as shown in FIG. The present shaped adhesive sheet laminate 1 having such a structure can be integrated as shown in FIG. The present adhesive sheet laminate is manufactured by forming uneven shapes. By manufacturing in the above-mentioned manner, the concavo-convex portion 2B of the adhesive sheet surface of the adhesive layer 2, the concavo-convex portion 3B of the protective sheet surface of the covering portion I, and the convex-concave portion 3D of the back surface of the protective sheet can respectively correspond to the same location to form concavities and convexities. The adhesive layer 2 can be used as, for example, a double-sided adhesive sheet for bonding two image display device constituent members (also referred to as "adherent bodies") constituting the image display device. That is, the surface concavities and convexities 2B of the adhesive sheet in the above-mentioned adhesive material layer 2 may correspond to the concavities, convexities, or concavities and convexities of the bonding surface of the adherend (referred to as "surface concavities and convexities of the adherend"). It is preferably formed into the same contour shape. Thereby, the surface irregularities 2B of the adhesive sheet in the shaped adhesive sheet laminate 1 can be fitted with the irregularities on the surface of the adherend in the image display device constituent member as the adherend. Here, as the above-mentioned image display device, for example, a liquid crystal display device (liquid crystal display, LCD), an organic EL (electroluminescence, electroluminescence) display device (OLED (organic light emitting diode, organic light emitting diode) )), electronic paper, microelectromechanical system (MEMS) displays and plasma displays (PDP) and other smart phones, tablet terminals, mobile phones, TVs, game consoles, personal computers, car navigation systems, ATM (automatic teller machine, automatic teller machine), fish detector, etc. But it is not limited to these. In addition, the so-called image display device constituent member as an adherend is a member that constitutes the image display device, and examples include surface protection panels, touch panels, image display panels, etc. The present shaped adhesive sheet laminate 1 For example, it can be used to bond any two adherends selected from a surface protection panel, a touch panel, and an image display panel. For example, it can be used to attach a surface protection panel to a touch panel, or a touch panel to an image display panel. However, the adherend is not limited to these. ＜Manufacturing method＞ Here, the manufacturing method of this shaped adhesive sheet laminated body 1 is demonstrated in detail. As described above, as shown in FIG. 2, the present adhesive sheet laminate 1 can be manufactured by forming the present adhesive sheet laminate 1 in an integrated manner by forming the present adhesive sheet laminate by heating. At this time, as the forming method, for example, press forming, vacuum forming, pressure forming, forming using rolls, forming using build-up, and the like can be cited. Among them, from the viewpoint of formability and processability, press molding is particularly preferable. A more detailed specific example will be explained. The laminated body of the adhesive sheet is preheated by a heater, and the laminated body of the adhesive sheet is transferred to the press forming machine at the stage of heating to a certain temperature, and the concave and convex shape corresponding to the printing step shape of the adherend is preliminarily imitated The mold is pressurized and cooled, so that the shape of the mold can be transferred to the single side of the adhesive sheet laminate, and the shape-shaped adhesive sheet laminate 1 with unevenness on the single side is manufactured. 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 to 70 to 120°C. The material of the mold used for the concave-convex shaping is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, and metal-based materials such as stainless steel or aluminum can be cited. Among them, since high-precision formability is required for the concave-convex shaping of the adherend, it is particularly preferable to be a metal-based mold that can control the temperature during forming. In addition, the cooling after the press processing can be performed after the mold is opened, or the mold can be cooled in advance, and the cooling can be performed while pressurizing. Furthermore, in the present invention, the molding conditions such as pressing pressure and pressing time are not specifically specified, and may be appropriately adjusted according to the size or shape of the molding, the material used, and the like. In addition, it is also possible to use a Thomson blade, a rotary cutter, or the like for cutting after the forming process. [The manufacturing method of this shaped adhesive sheet laminate] Then, the covering part I is provided with an adhesive material layer and laminated on one surface of the adhesive material layer in a peelable manner, and concave, convex, or concave-convex parts are formed on one surface of the adhesive material (referred to as "adhesive A particularly preferred form of the manufacturing method of the shaped adhesive sheet laminate constituted by the surface concavities and convexities of the material layer") will be described. The invention related to the present manufacturing method 1 and the present manufacturing method 2 described below proposes an adhesive material layer surface concavity and convexity that can be formed on the surface of the adhesive material layer with high accuracy that matches the concavity and convexity of the surface of the adherend, preferably A novel manufacturing method of shaped adhesive sheet laminate that can be manufactured continuously. As an example of the embodiment of the present invention, a novel method for manufacturing a shaped adhesive sheet laminate (referred to as "this manufacturing method 1") is proposed. The shaped adhesive sheet laminate system has an adhesive layer and a The coating part I is laminated on one side of the adhesive material layer by peeling, and concave, convex, or concavo-convex part is formed on one surface of the adhesive material (referred to as "surface concavo-convex part of the adhesive material layer"). The manufacturing method is characterized in that it is provided with an adhesive material layer and a covering portion I laminated on one side of the adhesive material layer in a peelable manner, and the adhesive sheet laminate is heated to heat the heated The adhesive sheet laminate is formed and cooled to produce a shaped adhesive sheet laminate manufacturing method, and the adhesive sheet laminate is heated, and the storage elastic modulus E'(MS) in the covering part I is 1.0× 10⁶ ～2.0×10⁹ Forming starts under the state of Pa, and the storage elastic modulus E'(MF) of the covering part I is 5.0×10⁷ ~1.0×10¹⁰ The forming is finished in the state of Pa. In this manufacturing method 1, a method for manufacturing the above-mentioned novel shaped adhesive sheet laminate is further proposed, which uses a cooled mold when forming the heated adhesive sheet laminate. According to the manufacturing method 1, for example, by heating the above-mentioned adhesive sheet laminate, the covering portion I starts to be formed in a specific state, and the covering portion I is finished forming in a specific state, and the surface of the adhesive layer can be accurately formed. The ground is formed into a concave-convex shape that matches the concave-convex part on the surface of the adherend. Furthermore, when the heated adhesive sheet laminate is formed, if a cooled mold is used for forming, the cooling can be performed at the same time as the forming, and the above-mentioned manufacturing method can be continuously performed. <This manufacturing method 1> This manufacturing method 1 is an example of the manufacturing method of the shaped adhesive sheet laminate (referred to as "this manufacturing method"), which includes heating the adhesive sheet laminate (heating step) described below, and heating the heated adhesive sheet laminate The manufacturing method of the step of forming the laminated body of the adhesive sheet and cooling it (forming, cooling step). The manufacturing method 1 may include other steps as long as it includes the above heating step and the above forming and cooling steps. For example, if necessary, steps such as a heat treatment step, a conveying step, a cutting step, a cutting step, etc. may be included. But it is not limited to these steps. (Adhesive sheet laminate) The adhesive sheet laminate as the starting member in the manufacturing method 1 may include an adhesive layer and a covering portion I that is releasably laminated on one surface of the adhesive layer, and may be provided with other members. For example, as shown in FIG. 1, it can be exemplified that an adhesive material layer is provided with a coating portion I that is peelably laminated on one of the front and back sides of the adhesive material layer, and the covering portion I is peelably laminated on the adhesive Adhesive sheet laminate of the covering part II formed on the other side of the front and back of the material layer. However, whether or not the covering portion II is provided is arbitrary, and a configuration in which the covering portion II is not laminated may also be adopted. In addition, the details of the adhesive sheet laminate are as described above. (Heating step) In this manufacturing method 1, it is preferable that the storage elastic modulus E'(M) of the coating portion I is 1.0×10 by heating the above-mentioned adhesive sheet laminate.⁶ ～2.0×10⁹ The state of Pa. If the storage elastic modulus E'(M) of the covering part I is in the above range, the covering part I can be deformed to a degree suitable for forming, and the surface of the adhesive layer can be accurately shaped to the required uneven shape . From this point of view, it is preferable that the storage elastic modulus E'(M) of the covering portion I is 1.0×10 by heating the adhesive sheet laminate.⁶ ～2.0×10⁹ The state of Pa, among which it is more preferable to set to 5.0×10⁶ Pa or above or 1.0×10⁹ The state below Pa, among them, it is more preferably set to 1.0×10⁷ Pa or more or 5.0×10⁸ The state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(M) of the covering portion I for heating the adhesive sheet laminate is 1.0×10⁶ ~1.0×10⁹ Pa, or 1.0×10⁶ ~5.0×10⁸ In the state, among them, it is more preferable to set to 5.0×10⁶ ～2.0×10⁹ Pa, or 5.0×10⁶ ~1.0×10⁹ The state of Pa, the best setting is 1.0×10⁷ ~1.0×10⁹ Pa, or 1.0×10⁷ ～～5.0×10⁸ The state. Here, in order to heat the adhesive sheet laminate so that the storage elastic modulus E'(M) of the covering part I is adjusted to the above-mentioned range, it can be adjusted according to the composition or gel content of the composition constituting the covering part I The rate, 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 part I is 1.0×10⁶ ～2.0×10⁹ Pa, and the storage elastic modulus G'(S) of the adhesive material layer is less than 1.0×10⁴ The state of Pa. If the storage elastic modulus E'(M) of the covering part I is adjusted to the above range, the above-mentioned effects can be obtained. Otherwise, if the storage elastic modulus G'(S) of the adhesive material layer does not reach 1.0 ×10⁴ Pa, can give sufficient formability to the adhesive layer. From this point of view, it is preferable that the storage elastic modulus E'(M) of heating the adhesive sheet laminate as the covering portion I is in the above range and the storage elastic modulus G'(S) of the adhesive layer does not reach 1.0×10⁴ The state of Pa, which is preferably set to 5.0×10¹ Pa or more or 5.0×10³ In the state below Pa, it is better to set to 1.0×10² Pa or above or 1.0×10³ The state below Pa. Accordingly, it is more preferable that the storage elastic modulus E'(M) of the covering portion I be the above range and the storage elastic modulus G'(S) of the adhesive layer is 5.0×10 for heating the adhesive sheet laminate.¹ Pa above and less than 1.0×10⁴ Pa, or 5.0×10¹ Pa or more and 5.0×10³ The state below Pa, among them, it is more preferably set to 1.0×10² Pa above and less than 1.0×10⁴ Pa, or 1.0×10² Pa or more and 5.0×10³ Below Pa, the best setting is 1.0×10² Pa or more and 1.0×10³ The 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 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. Furthermore, 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 has flexibility to the extent that it can be formed, so it is preferable. 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, and among them, it is more preferably 1.5 or more or 20 or less, and among them, it is still more preferable To make it 3.0 or more or 10 or less. However, the upper limit is not limited to this. In this manufacturing method 1, it is preferable to heat the adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive layer is sufficiently softened and the covering part I can be sufficiently deformed. If the temperature is below 180°C, the generation of wrinkles caused by heat shrinkage or heat can be suppressed. Decomposition of the adhesive material layer caused by the disadvantages, so it is better. From this point of view, 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, and among them, it is more preferably 75°C or higher or 150°C or lower, and among them, it is more preferably It becomes 80°C or higher or 120°C or lower. The heating method of the adhesive sheet laminate includes, for example, a method of heating the adhesive sheet laminate between the upper and lower heating plates provided with a heating body such as an electric heater, or directly sandwiching the adhesive sheet laminate. The method of holding, the method of using a heated roller, the method of immersing it in hot water, etc. But it is not limited to these methods. (Forming and cooling steps) In this step, the heated adhesive sheet laminate is formed as described above, and the adhesive sheet laminate is formed while cooling. That is, the adhesive sheet laminate in which the adhesive layer and the covering portion I are laminated is directly formed into an integrated state. As a result, the covering portion I is formed by the mold, and the adhesive material layer is also formed through the covering portion I. In this step, the heated adhesive sheet laminate may be cooled after being formed, or it may be cooled while being formed. For example, by using a cooled mold to pressurize, forming and cooling can be performed at the same time and finished at the same time. Thereby, this manufacturing method 1 can be continuously implemented as described below. As a molding method, the molding method is not particularly limited as long as the adhesive sheet laminate can be formed into an uneven shape in an integrated manner. For example, pressure forming, vacuum forming, air pressure forming, forming by rolls, compression forming, forming by lamination, etc. are mentioned. Among them, from the viewpoint of formability and processability, press molding is particularly preferable. The material of the mold is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, and metal-based materials such as stainless steel or aluminum can be cited. Among them, since high-precision formability is required for the concave-convex shaping of the adherend, it is particularly preferable to be a metal-based mold that can control the temperature during forming. The cooling method of the mold can be the usual cooling method. For example, water cooling or a cooling method using compressed air can be cited. For the mold, for example, as shown in FIG. 2, a specific concave-convex shape is provided in advance on the inner wall surface of at least one of the molds in a pair of open and closed molds, for example, in the bonding surface of the bonded body of the bonding material layer. Concave, convex, or concavo-convex shape conforming to the concavo-convex shape, and the above-mentioned concavo-convex shape can be transferred to the adhesive sheet by using the mold to press-form, vacuum-form, pressure-form or roll-form the adhesive sheet laminate Shaped by layered volumes. In this step, preferably as described above, the storage elastic modulus E'(MS) of the covering part I in the adhesive sheet laminate is 1.0×10⁶ ～2.0×10⁹ It begins to take shape in the state of Pa. Here, the so-called "beginning of forming", for example, in the case of forming using a mold, means that the mold is closed, that is, the sheet laminate is started to be pressed and adhered with the mold. If the storage elastic modulus E'(MS) of the covered part I is 1.0×10⁶ ～2.0×10⁹ In the range of Pa, the covering portion I can be deformed to a degree suitable for forming, and the surface of the adhesive layer can be accurately formed with the required uneven shape. From this point of view, it is preferable that the storage elastic modulus E'(MS) of the covering part I is 1.0×10⁶ ～2.0×10⁹ The forming of the adhesive sheet laminate starts under the state of Pa, and the better is 5.0×10⁶ Pa or above or 1.0×10⁹ Start forming under the condition of Pa below, more preferably 1.0×10⁷ Pa or more or 5.0×10⁸ Start forming under the condition of Pa below. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is 1.0×10⁶ ~1.0×10⁹ Pa, or 1.0×10⁶ ~5.0×10⁸ In the state of Pa, the formation of the adhesive sheet laminate is started, and among them, it is more preferably 5.0×10⁶ ~1.0×10⁹ Pa, or 5.0×10⁶ ~5.0×10⁸ Start forming under the state of Pa, the best is 1.0×10⁷ ~1.0×10⁹ Pa, or 1.0×10⁷ ~5.0×10⁸ It begins to take shape in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is 1.0×10⁶ ～2.0×10⁹ Pa, and the storage elastic modulus G'(SS) of the adhesive layer is less than 1.0×10⁴ In the state of Pa, the formation of the adhesive sheet laminate starts. If the storage elastic modulus E'(MS) of the covering part I is in the above range, the molding can be started, and the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G'( SS) less than 1.0×10⁴ Forming starts in the state of Pa, and forming can be carried out in a state where the adhesive layer has more sufficient formability. From this point of view, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is in the above-mentioned range and the storage elastic modulus G'(SS) of the adhesive layer is less than 1.0×10⁴ Forming starts under the state of Pa, and it is more preferable that the G'(SS) is 5.0×10¹ Pa or more or 5.0×10³ Start forming under the condition of Pa below, and more preferably at 1.0×10² Pa or above or 1.0×10³ Start forming under the condition of Pa below. Accordingly, it is more preferable that the storage elastic modulus E'(MS) of the covering part I is in the above range and the storage elastic modulus G'(SS) of the adhesive layer is 5.0×10¹ Pa above and less than 1.0×10⁴ Pa, or 5.0×10¹ Pa or more and 5.0×10³ Forming starts in the state below Pa, among which, it is more preferably 1.0×10² Pa above and less than 1.0×10⁴ Pa, or 1.0×10² Pa or more and 5.0×10³ Start forming under the condition of Pa below, the best is 1.0×10² Pa or more and 1.0×10³ Start forming under the condition of Pa below. In addition, it is preferable to start forming in a state where the surface temperature of the above-mentioned coated portion I is 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive layer is sufficiently softened and the covering part I can be sufficiently deformed. If it is 180°C or lower, the generation of wrinkles caused by thermal shrinkage or Disadvantages such as decomposition of the adhesive layer caused by heat, so it is better. Therefore, it is preferable to start forming in a state where the surface temperature of the coated portion I is 70 to 180°C, among them, it is more preferably to be 75°C or more or 150°C or less, and among them, it is more preferably to be 80°C or more or 120°C. ℃ below. On the other hand, in this step, it is preferable that the storage elastic modulus E'(MF) of the above-mentioned covering part I is 5.0×10⁷ ~1.0×10¹⁰ The forming is finished in the state of Pa. Here, the "finishing of molding" means the completion of the application of molding pressure to the adhesive sheet laminate, and in the case of mold molding, it means that the mold is opened. If the storage elastic modulus E'(MF) of the above-mentioned covering part I is 5.0×10⁷ Pa or more and 1.0×10¹⁰ The range of Pa or less has excellent shape stability after forming, so it is preferable. From this point of view, it is preferable that the storage elastic modulus E'(MF) of the covering portion I is 5.0×10⁷ ~1.0×10¹⁰ The forming is finished under the Pa state, and the better is 1.0×10⁸ Pa or above or 8.0×10⁹ Finish forming under Pa below state, more preferably 1.0×10⁹ Pa or more or 5.0×10⁹ Finish forming under Pa or below. Accordingly, in this step, it is more preferable that the storage elastic modulus E'(MF) of the above-mentioned covering part I is 5.0×10⁷ ～8.0×10⁹ Pa, or 5.0×10⁷ ~5.0×10⁹ The forming is finished in the state of Pa, among which, it is preferably 1.0×10⁸ ～8.0×10⁹ Pa, or 1.0×10⁸ ~5.0×10⁹ Finish forming under Pa state, the best is 1.0×10⁹ ～8.0×10⁹ Pa, or 1.0×10⁹ ~5.0×10⁹ The forming is finished in the state of Pa. Furthermore, it is more preferable that the storage elastic modulus E'(MF) of the covering portion I is in the above-mentioned range and the storage elastic modulus G'(SF) of the adhesive material layer is 1.0×10⁴ Finish forming at Pa or higher. If the molding is finished in the state where the storage elastic modulus E'(MF) of the coating part I is in the above range, the above-mentioned effects can be obtained. In addition, if the storage elastic modulus G'of the adhesive material layer is (SS) is 1.0×10⁴ When the forming is completed in the state above Pa, the formed adhesive layer can maintain its shape. From this point of view, it is preferable that the storage elastic modulus E'(MF) of the covering portion I is in the above range and the storage elastic modulus G'(SF) of the adhesive material layer is 1.0×10⁴ The forming is finished in the state above Pa, and it is more preferable that the storage elastic modulus G'(SF) of the adhesive material layer is 5.0×10⁴ Pa or more or 5.0×10⁷ Forming is finished in the state below Pa, and it is more preferably 1.0×10⁴ Pa or above or 1.0×10⁷ Finish forming under Pa or below. In addition, it is preferable to complete the molding in a state where the surface temperature of the above-mentioned covered portion I has reached less than 50°C. For example, in the case of press molding, it is preferable to open the mold when the surface temperature becomes less than 50°C. If the surface temperature of the covering part I has not reached 50℃, and the storage elastic modulus E'(MS) of the covering part I is 5.0×10⁷ ~1.0×10¹⁰ The range of Pa is preferable because it can suppress deformation when the molded body is taken out after the completion of molding, or warpage caused by thermal shrinkage of the coating portion I. From this point of view, it is preferable to finish forming when the surface temperature of the covering portion I becomes less than 50°C, and among them, it is preferable to finish forming when the surface temperature of the covering portion I becomes 0°C or higher or 45°C or lower, and among them, it is preferable to finish forming The molding is finished when the temperature reaches 10°C or higher or 40°C or lower. Furthermore, it is preferable that the storage elastic modulus E'(MS) of the covering part I at the beginning of forming and the storage elastic modulus E'(MF) of the covering part I at the end of forming satisfy the following relational expression (1) . (1)・・E'(MF)/E'(MS)≧1.3 Here, if the storage elastic modulus E'(MS) of the covering part I and the storage elastic modulus E'(MF) of the covering part I at the end of forming satisfy the above relational expression (1), then at the beginning of forming It is soft to the extent that it can be formed, and has hardness to the extent that it can maintain the formed shape after forming, so it is preferable. From this point of view, it is preferably E'(MF)/E'(MS)≧1.3, and more preferably 100≧E'(MF)/E'(MS) or E'(MF)/E' (MS)≧3.0, especially 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. In addition, it is preferable that the storage elastic modulus E'(MF) of the covering portion I at the end of the forming and the storage elastic modulus G'(SF) of the adhesive material layer at the end of the forming satisfy the following relational expression (2) . (2)・・E'(MF)/G'(SF)≦1.0×10⁷ Here, if the storage elastic modulus E'(MF) of the covering portion I at the end of forming and the storage elastic modulus G'(SF) of the adhesive material layer at the end of forming satisfy the above-mentioned relational expression (2), then The formed adhesive layer can maintain its shape. From this point of view, it is preferably E'(MF)/G'(SF)≦1.0×10⁷ , Where 1.0≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦5.0×10 is more preferred⁶ , Of which 1.0×10 is more preferred¹ ≦E'(MF)/G'(SF) or E'(MF)/G'(SF)≦1.0×10⁶ . Although there are some repetitions, in this manufacturing method 1, a mold can be used for pressure forming, and the mold can be cooled after the mold is opened, or the mold can be cooled in advance, and the pressure can be cooled at the same time as the pressure forming. If the mold is cooled in advance in this way, and the cooling is performed at the same time as the press molding, the molding and cooling can be completed at the same time. With this, the shaped adhesive sheet laminate can be transported to the next step immediately after the completion of forming and cooling, so that the shaped adhesive sheet laminate can be continuously manufactured. When cooling is performed while the mold is being formed, the surface temperature of the mold is preferably 0-50°C. If the surface temperature of the mold is below 50°C, the shape of the adhesive sheet laminate can be fixed in a short time, the obtained molded body has good accuracy, and the warpage accompanying heat shrinkage during the cooling process after molding can be suppressed. From this point of view, it is better. Therefore, the surface temperature of the mold is preferably 0-50°C, wherein it is more preferably 10°C or higher or 40°C or lower, and particularly preferably 15°C or higher or 30°C or lower. Furthermore, the conditions for press molding such as press pressure and press time are not particularly limited, and may be adjusted appropriately according to the size or shape of the molding, the material used, and the like. (other) The shaped adhesive sheet laminate obtained in the above-mentioned forming and cooling steps can be directly rolled up, and can also be heat-treated, and can also be cut into a specific size and shape. When cutting, for example, a method of cutting using a Thomson blade or a rotary cutter can be cited. In this manufacturing method 1, it is preferable to continuously manufacture the shaped adhesive sheet laminate. For example, the adhesive sheet laminate can be transported to a heating unit, such as a heater, where the transport is stopped for a specific time and heated, or the heated adhesive sheet laminate can be transported to forming after heating while being transported In a unit, such as a forming mold, in the forming unit, for example, the cooled mold is pressurized, is cooled while forming, and then is transported to the next unit as necessary to continuously manufacture the shaped adhesive sheet Layered body. ＜This manufacturing method 2＞ As an example of the embodiment of the present invention, a method for manufacturing a shaped adhesive sheet laminate (referred to as "this manufacturing method 2") is proposed. The shaped adhesive sheet laminate system has an adhesive layer and a peelable The covering part I is laminated on one surface of the adhesive material layer, and the structure is formed by forming concave, convex, or concavo-convex parts on one surface of the adhesive material (referred to as "concavo-convex part on the surface of the adhesive material layer"), The manufacturing method is characterized by heating an adhesive sheet laminate having an adhesive material layer and a coating part I laminated on one side of the adhesive material layer in a peelable manner, and the heated adhesive is adhered by a mold A method for manufacturing a shaped adhesive sheet laminate by forming a sheet laminate, and heating the adhesive sheet laminate to start forming when the surface temperature of the covering part I is 70 to 180°C, and then forming at the covering part I After the surface temperature became less than 60°C, the shaped adhesive sheet laminate was taken out from the mold. According to this manufacturing method 2, by heating the laminated body of the adhesive sheet, forming starts when the surface temperature of the covering part I is 70 to 180°C, and after the surface temperature of the covering part I becomes less than 60°C, it is removed from the mold The shaped adhesive sheet laminate is taken out, and for example, the surface of the adhesive layer can be accurately formed with a concave-convex shape corresponding to the concave-convex part of the surface of the adherend. This manufacturing method 2 is a manufacturing method including the steps of heating the adhesive sheet laminate described below (heating step), shaping the heated adhesive sheet laminate and cooling (forming, cooling step). This manufacturing method 2 may include other steps as long as it includes the above heating step and the above forming and cooling steps. For example, if necessary, steps such as a heat treatment step, a conveying step, a cutting step, a cutting step, etc. may be included. But it is not limited to these steps. (Adhesive sheet laminate) The adhesive sheet laminate as the starting member in the manufacturing method 2 may include an adhesive layer and a covering portion I laminated on one surface of the adhesive layer in a peelable manner, and may also include other members. For example, as shown in FIG. 1, it can be exemplified that an adhesive material layer is provided with a coating portion I that is peelably laminated on one of the front and back sides of the adhesive material layer, and the covering portion I is peelably laminated on the adhesive Adhesive sheet laminate of the covering part II formed on the other side of the front and back of the material layer. However, whether or not the covering portion II is provided is arbitrary, and a configuration in which the covering portion II is not laminated may also be adopted. In addition, the details of the adhesive sheet laminate are as described above. (Heating step) In this step, the above-mentioned adhesive sheet laminate is heated so that the surface temperature of the covering portion I becomes 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive layer is sufficiently softened and the covering part I can be sufficiently deformed. If the temperature is below 180°C, the generation of wrinkles caused by heat shrinkage or heat can be suppressed. Decomposition of the adhesive material layer caused by the disadvantages, so it is better. From this point of view, 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, and among them, it is more preferably 75°C or higher or 150°C or lower, and among them, it is more preferably It becomes 80°C or higher or 120°C or lower. Accordingly, it is more preferable to heat the above-mentioned adhesive sheet laminate so that the surface temperature of the covering portion I becomes 70-150°C, or 70-120°C, and among them, it is more preferably 75-150°C, or 75- 120°C, preferably 80 to 150°C, or 80 to 120°C. The heating method of the adhesive sheet laminate includes, for example, a method of heating the adhesive sheet laminate between the upper and lower heating plates provided with a heating body such as an electric heater, or directly sandwiching the adhesive sheet laminate. The method of holding, the method of using a heated roller, the method of immersing it in hot water, etc. But it is not limited to these methods. (Forming and cooling steps) In this step, it is preferable to start the formation of the adhesive sheet laminate in a state where the surface temperature of the covering portion I is heated to 70-180°C as described above. That is, it is preferable to directly shape an adhesive sheet laminate in a state where the adhesive layer and the covering portion I are laminated and integrated. In this way, the covering part I can be formed while the adhesive material layer is formed via the covering part I. In this step, the heated adhesive sheet laminate may be cooled after being formed, or it may be cooled while being formed. For example, by using a cooled mold to pressurize, forming and cooling can be performed at the same time and finished at the same time. Thereby, this manufacturing method 2 can be continuously implemented as described below. As a molding method, the molding method is not particularly limited as long as the adhesive sheet laminate can be formed into an uneven shape in an integrated manner. For example, pressure forming, vacuum forming, air pressure forming, forming by rolls (roll forming), compression forming, forming by lamination, etc. are mentioned. Among them, from the viewpoint of formability and processability, press molding is particularly preferable. When a mold is used for forming, the material of the mold is not particularly limited. For example, resin-based materials such as silicone resin and fluororesin, and metal-based materials such as stainless steel or aluminum can be cited. Among them, since high-precision formability is required for the concave-convex shaping of the adherend, it is particularly preferable to be a metal-based mold that can control the temperature during forming. The cooling method of the mold can be the usual cooling method. For example, water cooling or a cooling method using compressed air can be cited. For the mold, for example, as shown in FIG. 2, a specific concave-convex shape is provided in advance on the inner wall surface of at least one of the molds in a pair of open and closed molds, for example, in the bonding surface of the bonded body of the bonding material layer. Concave, convex, or concavo-convex shape corresponding to the concavo-convex part, and the above-mentioned concavo-convex shape can be transferred to the adhesive sheet by using the mold to press-form, vacuum-form, pressure-form or roll-form the adhesive sheet laminate Shaped by layered volumes. As described above, it is preferable to start forming in a state where the surface temperature of the coating portion I is 70 to 180°C. If the surface temperature of the covering part I is 70°C or higher, the adhesive material layer is sufficiently softened and the covering part I can be sufficiently deformed. If the temperature is below 180°C, the generation of wrinkles caused by thermal shrinkage can be suppressed or caused by Disadvantages such as decomposition of the adhesive layer caused by heat, so it is better. Therefore, it is preferable to start forming in a state where the surface temperature of the coated portion I is 70 to 180°C, among them, it is more preferably to be 75°C or more or 150°C or less, and among them, it is more preferably to be 80°C or more or 120°C. ℃ below. On the other hand, in this step, it is preferable to complete the forming when the surface temperature of the above-mentioned covering portion I becomes less than 60°C. For example, in the case of press molding, it is preferable to open the mold when the surface temperature becomes less than 60°C. Here, the "finishing of molding" means the completion of the application of molding pressure to the adhesive sheet laminate, and in the case of mold molding, it means that the mold is opened. If the surface temperature of the coated portion I is less than 60° C., it is possible to suppress deformation when the molded body is taken out after the molding is completed, or warpage accompanying thermal shrinkage of the coated portion I, which is preferable. From this point of view, it is preferable to complete the molding in a state where the surface temperature of the covering portion I becomes less than 60°C, and among them, it is preferable to complete the molding in a state where the surface temperature of the covering portion I becomes 0°C or higher or 50°C or less, and among them, The molding is finished when the temperature reaches 10°C or higher or 40°C or lower. Although there are some repetitions, in this manufacturing method 2, the mold can be press-formed and cooled after the mold is opened, or the mold can be pre-cooled and cooled while press-forming. If the mold is cooled in advance in this way, and the cooling is performed at the same time as the press molding, the molding and cooling can be completed at the same time. With this, the shaped adhesive sheet laminate can be transported to the next step immediately after the completion of forming and cooling, so that the shaped adhesive sheet laminate can be continuously manufactured. When cooling is performed while the mold is being formed, the surface temperature of the mold is preferably less than 60°C. If the surface temperature of the mold is less than 60°C, the shape of the laminated body of the adhesive sheet can be fixed in a short time, the formed body obtained has good accuracy, and the warpage accompanying heat shrinkage during the cooling process after forming can be suppressed. From this point of view, it is better. Therefore, the surface temperature of the mold is preferably less than 60°C, wherein it is more preferably 0°C or higher or 50°C or lower, and particularly preferably 10°C or higher or 40°C or lower. In addition, the difference between the surface temperature of the coated portion I at the beginning of the molding and the end of the molding is preferably 10 to 100°C, and more preferably 20°C or higher or 90°C or lower. Since the difference in the surface temperature of the covering portion I is 10-100°C, for example, when the concave-convex shape is transferred to the adhesive sheet laminate for shaping, the shaped adhesive sheet can be formed immediately after the completion of forming and cooling. The laminated body is transported to the next step, so that the shaped adhesive sheet laminated body can be manufactured continuously. Furthermore, the conditions for press molding such as press pressure and press time are not particularly limited, and may be adjusted appropriately according to the size or shape of the molding, the material used, and the like. (other) The shaped adhesive sheet laminate obtained in the above-mentioned forming and cooling steps can be directly rolled up, and can also be heat-treated, and can also be cut into a specific size and shape. When cutting, for example, a method of cutting using a Thomson blade or a rotary cutter can be cited. In this manufacturing method 2, it is preferable to continuously manufacture the shaped adhesive sheet laminate. For example, the adhesive sheet laminate can be transported to a heating unit, such as a heater, where the transport is stopped for a specific time and heated, or the heated adhesive sheet laminate can be transported to forming after heating while being transported In a unit, such as a forming mold, in the forming unit, for example, the cooled mold is pressurized, is cooled while forming, and then is transported to the next unit as necessary to continuously manufacture the shaped adhesive sheet Layered body. ＜Use＞ Here, an example of the use of the shaped adhesive sheet laminate 1 will be described. In recent years, with the generalization of mobile phones, smart phones, and tablet terminals, there have been many instances of damage to the image display unit due to users dropping them by mistake. Especially when the image display device is a touch panel method, not only is it difficult to observe the display due to damage, but also because of physical obstacles or water infiltration, the touch panel operation itself cannot be performed or the cause of failure . Therefore, there are cases in which repairs that only replace the image display unit, that is, repairs are performed. In the maintenance of image display devices, adhesive sheets are also used when installing new image display units. Normally, in many cases, the repair operator must perform manual work, and the repair operator must be skilled. That is, if an unskilled person, when installing the image display part through the adhesive sheet, air may enter the inside or the adhesive may be pushed out. On the other hand, if this shaped adhesive sheet laminate 1 is used, it is possible to provide a high-precision stepped shape in advance. Therefore, for example, the adhesive layer is provided in advance to correspond to the model of the image display device. The stepped shape greatly simplifies maintenance operations, and can be implemented without the skill of repair operations. As described above, the adhesive sheet laminate of the present invention can be usefully used for maintenance of image display devices. ＜Description of sentence＞ In this manual, when it is expressed as "X～Y" (X and Y are arbitrary numbers), unless otherwise specified, it means "more than X and less than Y", and also includes "preferably The meaning of "greater than X" or "preferably less than Y".

The molding is completed after the surface temperature of the covering part 3-I reaches less than 60°C, and the molded product is taken out from the mold to perform molding, so that the adhesive layer can be formed with high-precision uneven shapes. On the other hand, as shown in Comparative Example 3-1, if the temperature of the coating portion 3-I at the start of forming is less than 70°C, the adhesive layer cannot be formed with sufficient concavities and convexities even if thermoforming is performed. In addition, as shown in Comparative Example 3-2, if the surface temperature of the coated portion 3-I is 70°C or higher when the molding is completed and the molded product is taken out from the mold, the molded product will warp due to thermal shrinkage of the sheet. Curved or bent and not good. From this, it can be seen that in order to perform uneven shaping with higher accuracy, it is preferable to start molding in a state where the surface temperature of the covering part 3-I is 70 to 180°C, and the surface temperature of the covering part 3-I becomes unpredictable. After the temperature reaches 60°C, the molding is finished, and the molded product is taken out from the mold to perform molding. Therefore, it was confirmed that by using the adhesive sheet laminate as described above, the unevenness equivalent to the printing step of the image display device that becomes the adherend can be formed accurately, and there is no gap between the adherend and the adherend. In addition, even in an adherend with a narrow-edge design for the printing part, the adhesive material can not overflow, and is well-adhered and adhered to a shaped adhesive sheet laminate for image display devices. Regarding the peeling force, the heating and cooling conditions when measuring the peeling force F(D), that is, heating at 100°C for 5 minutes and then natural cooling to 30°C are the conditions when manufacturing the shaped adhesive sheet laminate. Typical heating and cooling conditions. Since the absolute value of the difference between the peeling force F (C) and the peeling force F (D) in the above examples is 0.1 N/cm or less, it is confirmed that the peeling force hardly changes before and after heating.

The evaluation results are shown in Table 4 below. [Example 4-2], [Example 4-3] Except for changing the conditions shown in Table 4 below, a polyester film was obtained in the same manner as in Example 4-1.

[Example 4-4] The above-mentioned polyester 4-A and 4-C were mixed in the proportions of 86% by weight and 14% by weight respectively as the raw material for the surface layer, so that the polyester 4-B and 4-A were respectively 45% by weight , 55% by weight mixed raw materials are used as raw materials for the intermediate layer. They were melted and extruded by different melt extruders to obtain two kinds of amorphous sheets with three layers (surface layer/middle layer/surface layer). Then, by co-extruding the sheet onto a cooled casting drum and allowing it to cool and solidify, a non-aligned sheet is obtained. Then, after stretching 3.4 times in the machine direction (MD) at 82°C, it is further subjected to a preheating step in the stretcher, and then stretched 3.9 times in the direction perpendicular to the machine direction (width direction, TD) at 110°C. After the biaxial stretching is performed, heat treatment is performed at 210°C for 3 seconds, and then a relaxation treatment of 2.4% in the width direction is performed to obtain a polyester film with a thickness of 50 μm.
