| description | To provide an adhesive for a film, which less likely causes decrease in the adhesive force with time even in a high temperature environment.SOLUTION: The adhesive for a film of the present invention contains a copolymer (A) of at least the following component (a) by 30 to 90 pts.mass, the following component (b) by 15 to 30 pts.mass and the following component (c), in which the copolymer (A) has a weight average molecular weight of 100000 to 400000. The components are: (a) at least either an alkyl acrylate having an alkyl group having 8 to 12 carbon atoms or an alkyl methacrylate having an alkyl group having 8 to 12 carbon atoms; (b) an alkyl methacrylate having an alkyl group having 1 to 3 carbon atoms; and (c) a monomer having a crosslinking functional group.SELECTED DRAWING: None
【課題】 高温環境下でも接着力の経時的低下が起こりにくいフィルム用粘着剤を提供する。【解決手段】 前記目的を達成するために、本発明のフィルム用粘着剤は、少なくとも下記成分（ａ）３０〜９０質量部、下記成分（ｂ）１５〜３０質量部および下記成分（ｃ）の共重合体（Ａ）を含み、前記共重合体（Ａ）の重量平均分子量が１０万〜４０万であることを特徴とする。（ａ）炭素数８〜１２のアルキル基を有するアクリル酸アルキルエステルおよび炭素数８〜１２のアルキル基を有するメタクリル酸アルキルエステルの少なくとも一方（ｂ）炭素数１〜３のアルキル基を有するメタクリル酸アルキルエステル（ｃ）架橋性官能基を有するモノマー【選択図】 なし |
