Abstract

There is provided an optical film pressure-sensitive adhesive composition capable of forming a pressure-sensitive adhesive layer that has reworkability such that optical films therewith can be easily separated from liquid crystal panels with no adhesive residue and also has satisfactory processability such that it can be processed without causing adhesive stain or dropout after it is formed on an optical film. The optical film pressure-sensitive adhesive composition includes 100 parts by weight of a (meth)acrylic polymer including, as monomer units, (a) 50 to 99.79% by weight of an alkyl (meth)acrylate monomer, (b) 0.01 to 0.45% by weight of a tertiary amino group-containing monomer, and (c) 0.1 to 3% by weight of a hydroxyl group-containing monomer; and 0.01 to 2 parts by weight of a crosslinking agent that is at least one selected from the group consisting of hexamethylene diisocyanate, hydrogenated xylylene diisocyanate, and isophorone diisocyanate, or a polyisocyanate compound derived therefrom.
