Pressure sensitive adhesives for optical film, manufacturing methods for pressure sensitive adhesive layer for optical film, pressure sensitive adhesive layers for optical film, pressure sensitive adhesion type optical films and image displays

A pressure sensitive adhesion type 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) including an alkyl (meth)acrylate (a1) and a (meth)acrylic-based monomer containing a hydroxyl group (a2), as a copolymerizable component, 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);
• 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.
