Abstract:
1. A pressure-sensitive adhesive composition for an optical film, comprising: a (meth)acrylic polymer comprising (a) 34 to 94% by weight of an alkyl (meth)acrylate monomer unit, (b) 5 to 50% by weight of an aromatic ring-containing (meth)acrylate monomer unit, and (c) 0.01 to 0.5% by weight of an amino group-containing (meth)acrylate monomer unit; 0.01 to 2 parts by weight of a peroxide based on 100 parts by weight of a (meth)acrylic polymer; and 0.01 to 2 parts by weight of a silane coupling agent based on 100 parts by weight of a (meth)acrylic polymer, wherein the (meth)acrylic polymer has a weight average molecular weight of 1,800,000 to 2,800,000 as determined by gel permeation chromatography.
