Abstract
A pressure-sensitive adhesive composition for an optical film of the present invention comprises 100 parts by weight of a (meth)acrylic polymer comprising 45 to 99.99% by weight of an alkyl (meth)acrylate monomer unit and 0.01 to 2% by weight of a tertiary amino group-containing monomer unit; and 0.01 to 2 parts by weight of a peroxide as a crosslinking agent. The pressure-sensitive adhesive composition can form an pressure-sensitive adhesive layer that has satisfactory reworkability such that optical films can be easily peeled from liquid crystal panels with no adhesive residue and also has satisfactory processability such that it can be worked without pressure-sensitive adhesive fouling or dropout.
