Patent ID: 8188194

Claim:
An adhesive composition for polarizing plates, in which a (meth)acrylic polymer, a cross-linker, and a cross-linking accelerator are dissolved in an organic solvent, the (meth)acrylic polymer being formed by copolymerization of monomers containing an alkyl (meth)acrylate, a hydroxyl group containing monomer, and/or a carboxyl group containing monomer, wherein a solution containing 30% by weight of (meth)acrylic polymer which constitutes the adhesive composition, dissolved in 70% by weight of ethyl acetate has a viscosity in the range of 0.5 to 10.0 Pa·s measured at 23° C., the (meth)acrylic polymer having a weight-average molecular weight in the range of 300,000 to 900,000 is crosslinked with an isocyanate cross-linker in the presence of the cross-linking accelerator, and the adhesive composition for polarizing plates contains 25 to 60% by weight of non-volatile matter.
