Adhesive of (meth)acrylate polymer, peroxide and isocyanate laminated on optical film

A pressure sensitive adhesion optical film in which a pressure sensitive adhesive layer for an optical film is laminated on at least one surface of the optical film, wherein the pressure sensitive adhesive layer for an optical film comprises a pressure sensitive adhesive layer formed by:

• cross-linking a pressure sensitive adhesive for an optical film, wherein the pressure sensitive adhesive for an optical film comprises:
• 100 parts by weight of a (meth)acrylic-based polymer (A) consisting of an alkyl (meth)acrylate (a1), a (meth)acrylic-based monomer containing a hydroxyl group (a2) in content in the range of from 0.01 to 5 parts by weight relative to 100 parts by weight of the alkyl (meth)acrylate (a1), and one or more copolymerizable compounds without a functional group, each in the content range of from 0 to 100 parts by weight relative to 100 parts by weight of the alkyl (meth)acrylate (a1), wherein said copolymerizable compound without a functional group is selected from the group consisting of benzyl (meth)acrylate, methoxyethyl (meth)acrylate, ethoxymethyl (meth)acrylate, phenoxyethyl (meth)acrylate, (meth)acrylamide, vinyl acetate, and (meth)acrylonitrile;
• 0.02 to 2 parts by weight of a peroxide (B);
• 0.001 to 2 parts by weight of an isocyanate-based compound (C), the contents of the peroxide (B) and the isocyanate-based compound (C) being values relative to 100 parts by weight of the (meth)acrylic-based polymer (A);
• and
• a silane coupling agent.
