ADHESIVE COMPOSITION FOR POLARIZING PLATES AND POLARIZING PLATE HAVING ADHESIVE LAYER

摘要

[Problem] To provide an adhesive composition for polarizing plates, suitable for configurations whereby at least one polarizer protective film normally formed on both surfaces of a polarizer is omitted, whereby warping (bending) of liquid crystal cells can be suppressed and an adhesive layer having excellent durability can be formed. [Solution] An adhesive composition for polarizing plates, characterized by containing a (meth) acrylate copolymer and a cross linking agent (B) and by being used to form an adhesive layer that comes directly in contact with polarizers. The (meth) acrylate copolymer is obtained by copolymerization of monomer components including: at least 30% by mass and less than 90% by mass of a methacrylate alkyl ester (a1) having a homopolymer glass transition temperature of less than -30°C; at least 10% by mass and less than 70% by mass of a methacrylate alkyl ester (a2) having a homopolymer glass transition temperature of at least -30°C; and more than 0% by mass and no more than 10% by mass of crosslinking functional group-containing monomer (a3).
