Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to an adhesive tape. More specifically, it is possible to effectively protect the surface of the surface from which the surface has irregularities. The adhesive tape of the present invention is, for example, a surface protective film which imparts a design to the concave-convex member by forming irregularities on the surface of the automobile industry, or can effectively protect a plurality of triangular prism-shaped ribs on the surface. The surface protection film of the lens surface of the lens of the mirror is particularly useful. [Prior Art] In order to protect the surface of each of the adhesives, an adhesive layer _ tape is widely used on the surface of the film-form substrate layer. On the other hand, there are many members which have irregularities formed on the surface for the purpose of imparting design, workability, optical functionality, and the like. Formed on such a surface
凹凸的構件中，存在有於凹凸部分附著灰塵或者於凸部分發 生傷痕的問題。為了 方+ & # BS ^ Θ了防止此種問題’而使用如上上述的黏著 ηψ。 此種黏著帶，係在保護表面形成有凹凸之構件的期時，需 要不剝離的黏著力。因此，需要作成為在黏著劑層中使用柔 軟的黏著劑，並具有高黏著力的黏著帶。但是，當在黏著劑 層中使用柔軟的黏著劑時’將產生屬於被黏物的表面上形成 有凹凸之構件中的凹凸頂部突破黏著劑層而觸及基材層，而 使凹凸頂部變形的問題。 099123258 201109408 另一方面，若表面形成有凹凸的構件與黏著帶的黏著力過 強，則從表面形成有凹凸的構件上剝離黏著帶時，將產生無 法順利剝離的問題。 因此，用於保護表面形成有凹凸之構件的黏著帶的黏著劑 層，需要具有黏著性與剝離性兩種相反的性能，同時，♦要 具有在保護時使凹凸頂部無法觸及黏著帶基材層之程度的 硬度。 作為具有特殊之黏著劑層的黏著帶，已揭示有使用以苯乙 烯系彈性體為域分的厚度1()μηι以下的黏著劑層的黏著 帶(例如，曰本專利特開20〇7_332329號公報）。 但是，日本專利特開2007_332329號公報中揭示的黏著 帶，係當用於表面形成有凹凸之構件的表面保護時，產生凹 凸頂部突破黏著劑層而觸及基材層、而使凹凸頂部變形的問 題。另外，在日本專利特開2007_332329號公報中所揭示的 黏著帶，仙其材料的選擇，產生黏著力不充分而從被黏物 上自然剝離的問題，或者黏著力過強而無法從獅物上順利 剝離的問題。 另外，一般為了保護各種被黏物的表面，廣泛使用在膜狀 的基材層的一面上積層了黏著劑層的表面保護膜。 另一方面，在片材表面固定了複數個三稜柱狀稜鏡的稜鏡 片被使用於各種光學裝置上。在此種稜鏡片巾，存在有透鏡 面（稜鏡面）附著灰塵，或者透鏡部分(稜鏡部分)產生劃痕的 099123258 5 201109408 問題。為了防止此種問題，而使用如上上述的表面保護膜。 對於保護棱鏡片表面的表面保護膜而言，需要具有保護時 不剝離、不需要保護而予以剝離時能夠順利剝離的穩定黏著 力。另外，用此種表面保護膜保護稜鏡片時，必須對精密成 形的棱鏡圖案不造成光學性不良影響。 迄今，在稜鏡片等光學構件用的表面保護膜中，一般使用 橡膠系黏著劑作為黏著劑（例如，曰本專利特開平11-181370 號公報）。 另一方面，貼合有表面保護膜的棱鏡片，係依積層的狀態 或長卷的狀態等在步驟間進行輸送。在如此使稜鏡片積層等 時，由於稜鏡片本身重量，有時會使稜鏡片的透鏡部分(稜 鏡部分）不均地深陷入表面保護膜中。如此，當貼合了表面 保護膜的稜鏡片的外觀產生不均（壓痕）時，將難以在貼合了 表面保護膜的狀態下進行稜鏡片的外觀檢查。 【發明内容】 (發明所欲解決之問題） 本發明係為了解決上述現有問題而完成者，其目的在於提 供一種能夠保護表面具有凹凸之構件的凹凸面的黏著帶，其 同時具有對該構件的充分黏著性與充分剝離性，並且將用該 黏著帶保護的該構件作成為積層或長卷等而變形時該凹凸 形狀亦不變形，而且不劃傷該黏著帶中的基材層。另外，本 發明的目的在於提供一種可用於作為稜鏡片用表面保護膜 099123258 6 201109408 的黏著帶，該表面保護膜能夠有效保護例如表面固定有複數 個三棱柱狀稜鏡的稜鏡片的透鏡面，同時具有對稜鏡片的充 分黏著性與充分的剝離性，並且將用該表面保護膜保護的稜 鏡片作成為積層或長卷等狀態時，可以抑制黏貼有該表面保 護膜的棱鏡片的外觀產生不均（壓痕）。 (解決問題之手段） 本發明的黏著帶，係依次具有基材層、第一黏著劑層與第 二黏著劑層，其中，該基材層包含熱可塑性樹脂，該第一黏 著劑層的儲藏彈性係數高於該第二黏著劑層的儲藏彈性係 數，該第一黏著劑層的頻率10Hz、23°C下的儲藏彈性係數 與該第二黏著劑層的頻率10Hz、23°C下的儲藏彈性係數之 差為3xl05Pa以上。 在較佳的實施形態中，上述第一黏著劑層的儲藏彈性係數 在頻率10Hz、23°C下為1.0><106Pa以上且未滿1.0xl09Pa。

凸面的黏著帶，其同時具有對該構件的充分黏著性與充分剝 離性，並且將用該黏著帶保護的該構件作成為積層或長卷等 而變形時該凹凸形狀也不變形，而且不劃傷該黏著帶中的基 材層。另外，可以提供可用於作為稜鏡片用表面保護膜的黏 著帶，該表面保護膜能夠有效保護例如表面固定有複數個三 稜柱狀稜鏡的稜鏡片的透鏡面，同時具有對稜鏡片的充分黏 著性與充分的剝離性，並且將用該表面保護膜保護的棱鏡片 作成為積層或長卷等狀態時，可以抑制黏貼有該表面保護膜 的稜鏡片的外觀產生不均（壓痕）。 【實施方式】 A.黏著帶 本發明的黏著帶，係依次具有基材層、第一黏著劑層與第 二黏著劑層。圖1為本發明的較佳實施形態的黏著帶的概略 剖面圖。黏著帶100具有基材層1、在基材層1的單側或兩 側（圖示例中為單側）上設置的第一黏著劑層21與在第一黏 著劑層21的與基材層1相反側上設置的第二黏著劑層22。

is a problem that dust adheres to the concavo-convex portions or scratches occur in the convex portions. In order to prevent this problem, the square + &# BS ^ uses the above-mentioned adhesion ηψ. Such an adhesive tape requires an adhesive force that does not peel off when the surface of the protective surface is formed with irregularities. Therefore, it is necessary to use an adhesive tape which has a soft adhesive in the adhesive layer and has a high adhesive force. However, when a soft adhesive is used in the adhesive layer, the problem arises that the top of the uneven portion in the member having the unevenness on the surface of the adherend breaks through the adhesive layer and touches the substrate layer, thereby deforming the top portion of the uneven portion. . On the other hand, when the adhesive force between the member having the uneven surface formed on the surface and the adhesive tape is too strong, when the adhesive tape is peeled off from the member having the uneven surface formed thereon, there is a problem that the peeling cannot be smoothly performed. Therefore, the adhesive layer for protecting the adhesive tape of the member having the uneven surface formed needs to have the opposite properties of adhesiveness and peeling property, and at the same time, ♦ the top of the unevenness cannot be touched to the adhesive tape substrate layer during protection. The degree of hardness. As an adhesive tape having a special adhesive layer, an adhesive tape using an adhesive layer having a thickness of 1 (? μηι or less) as a domain of a styrene-based elastomer has been disclosed (for example, Japanese Patent Laid-Open No. Hei 20 No. 7-332329 Bulletin). However, the adhesive tape disclosed in Japanese Laid-Open Patent Publication No. 2007-332329 is a problem that when the surface of the member having the uneven surface formed thereon is protected, the uneven top portion breaks through the adhesive layer and touches the base material layer to deform the uneven top portion. . In addition, the adhesive tape disclosed in Japanese Laid-Open Patent Publication No. 2007-332329, the selection of the material of the material, causes the problem that the adhesion is insufficient and is naturally peeled off from the adherend, or the adhesion is too strong to be able to be removed from the lion. The problem of smooth stripping. Further, in general, in order to protect the surface of various adherends, a surface protective film in which an adhesive layer is laminated on one surface of a film-form substrate layer is widely used. On the other hand, a sheet in which a plurality of triangular prism-shaped crucibles are fixed on the surface of the sheet is used for various optical devices. In such a crepe wiper, there is a problem that the lens surface (the enamel surface) is attached with dust, or the lens portion (the enamel portion) is scratched by 099123258 5 201109408. In order to prevent such a problem, the surface protective film as described above is used. The surface protective film for protecting the surface of the prism sheet needs to have a stable adhesive force which can be smoothly peeled off without peeling off during protection and peeling off without protection. Further, when the ruthenium sheet is protected by such a surface protective film, it is necessary to prevent optically adverse effects on the precisely formed prism pattern. In the surface protective film for an optical member such as a crepe sheet, a rubber-based adhesive is generally used as the adhesive (for example, Japanese Laid-Open Patent Publication No. Hei 11-181370). On the other hand, the prism sheet to which the surface protective film is bonded is conveyed between steps in a state of being laminated or in a state of a long roll. When the enamel sheet is laminated or the like, the lens portion (the prism portion) of the cymbal sheet sometimes falls unevenly into the surface protective film due to the weight of the cymbal sheet itself. When the appearance of the enamel sheet to which the surface protective film is bonded is uneven (indentation), it is difficult to perform the visual inspection of the enamel sheet in a state in which the surface protective film is bonded. DISCLOSURE OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION The present invention has been made to solve the above conventional problems, and an object thereof is to provide an adhesive tape capable of protecting an uneven surface of a member having irregularities on a surface thereof, which simultaneously has the member Adhesiveness and sufficient peelability are sufficient, and the member protected by the adhesive tape is not deformed when it is deformed by lamination or long rolling, and the base material layer in the adhesive tape is not scratched. Further, an object of the present invention is to provide an adhesive tape which can be used as a surface protection film for a crepe sheet 099123258 6 201109408, which is capable of effectively protecting a lens surface of a cymbal sheet having a plurality of triangular prismatic cymbals fixed on its surface, for example.
