Patent ID: 8399090

Claim:
A pressure-sensitive adhesive layer, comprising a product produced by crosslinking a pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive composition is for use in optical members and is comprising: 100 parts by weight of a (meth)acrylic polymer comprising as monomer units 50 to 98% by weight of a (meth)acrylic monomer represented by general formula CH 2 ═C(R 1 )COOR 2 , wherein R 1 is hydrogen or a methyl group, and R 2 is an alkyl group having 2 to 14 carbon atoms, and 0.1 to 35% by weight of a nitrogen-containing monomer; 0.02 to 2 parts by weight of a peroxide as a crosslinking agent; 0.02 to 2 parts by weight of an isocyanate crosslinking agent; and an organic solvent, and wherein the pressure-sensitive adhesive layer has a gel fraction of 55 to 95% by weight.
