ADHESIVE COMPOSITION FOR POLARIZING PLATES, ADHESIVE LAYER AND POLARIZING PATE WITH ADHESIVE LAYER

摘要

Provided is an adhesive composition for polarizing plates, which does not deteriorate the optical characteristics of a polarizing plate even in cases where an adhesive layer is formed on a polarizing plate having a polarizer protective layer that has a thin film thickness or on a polarizing plate having no polarizer protective layer. An adhesive composition for polarizing plates according to the present invention contains (A) an ionic compound, (B) a (meth)acrylic copolymer having a crosslinkable functional group and (C) a crosslinking agent, and is characterized in that the ionic compound (A) is composed of a cationic moiety and an anionic moiety and has one or more reactive functional groups in the cationic moiety.
