Document Type and Number:
WIPO Patent Application WO/2016/072201
Kind Code:
A1
Abstract:
[Problem] To provide an adhesive composition for polarizing plates that: contains a crosslinking agent and a (meth) acrylic copolymer obtained by polymerization of a (meth) acrylate alkyl ester; and is capable of forming an adhesive layer having excellent durability and light-leakage prevention characteristics. [Solution] An adhesive composition for polarizing plates, characterized by containing a (meth) acrylic copolymer (A) and a crosslinking agent (B), said (meth) acrylic copolymer (A) being obtained by copolymerization of monomer components including a (meth) acrylate alkyl ester (a1) having a homopolymer photoelastic coefficient of -1,000 × 10-12 - -100 × 10-12 (m2/N), a (meth) acrylate alkyl ester (a2) having a homopolymer photoelastic coefficient of +100 × 10-12 - +1,000 × 10-12 (m2/N), and a crosslinking functional group-containing monomer (a3).
