Title:
ADHESIVE COMPOSITION FOR POLARIZING PLATES, POLARIZING PLATE WITH ADHESIVE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/030080
Kind Code:
A1
Abstract:
The present invention provides an adhesive composition for polarizing plates, which contains a polyvalent isocyanate compound and a (meth)acrylic copolymer that contains a structural unit derived from a monomer having a cyclic group, said structural unit being contained in an amount of 2-9% by mass relative to the total mass of the copolymer, a structural unit derived from a monomer having a hydroxyl group and a structural unit derived from an alkyl (meth)acrylate. The (meth)acrylic copolymer has a weight average molecular weight of 800,000-1,800,000 and a degree of dispersity (weight average molecular weight/number average molecular weight) of 4-9.
