Description

すなわち本発明の粘着剤シートは、以下に示す（メタ）アクリル酸エステル（Ａ−１）９４.８〜９９.８９重量％、水酸基を有する（メタ）アクリル系単量体（Ａ−２） ０.１〜５重量％、及び以下に示すカルボキシル基含有（メタ）アクリル酸エステル（Ａ−３）０.０１〜０.２重量％を含む単量体混合物から得られる共重合体であって、重量平均分子量が１００万〜２００万であるアクリル樹脂（Ａ）１００重量部、並びに架橋剤（Ｂ）０.０１〜５重量部を含有する粘着剤組成物からシート状に形成されているものである。 That is, the pressure-sensitive adhesive sheet of the present invention has the following (meth) acrylic acid ester (A-1) 94.8 to 99.89% by weight, (meth) acrylic monomer (A-2) 0 having a hydroxyl group. A copolymer obtained from a monomer mixture containing 0.1 to 5% by weight and the following carboxyl group-containing (meth) acrylic acid ester (A-3) 0.01 to 0.2% by weight, It is formed into a sheet from a pressure-sensitive adhesive composition containing 100 parts by weight of an acrylic resin (A) having a weight average molecular weight of 1,000,000 to 2,000,000 and 0.01 to 5 parts by weight of a crosslinking agent (B). is there.

単量体（Ａ−２）は、水酸基を有する（メタ）アクリル系単量体であり、その例としては、（メタ）アクリル酸２−ヒドロキシエチル、（メタ）アクリル酸３−ヒドロキシプロピル、（メタ）アクリル酸４−ヒドロキシブチル、（メタ）アクリル酸２−（２−ヒドロキシエトキシ）エチルなどが挙げられる。これらのなかでも、（メタ）アクリル酸２−ヒドロキシエチルを、アクリル樹脂（Ａ）を構成する単量体（Ａ−２）の一つとして用いるのが好ましい。
The monomer (A-2) is a (meth) acrylic monomer having a hydroxyl group. Examples thereof include 2-hydroxyethyl (meth) acrylate, 3-hydroxypropyl (meth) acrylate, ( Examples include 4-hydroxybutyl (meth) acrylate and 2- (2-hydroxyethoxy) ethyl (meth) acrylate. Among these, a (meth) acrylate, 2-hydroxyethyl le, is preferably used as one of the monomers constituting the acrylic resin (A) (A-2).
