WIPO Patent Application WO/2015/141382
Kind Code:
A1
Abstract:
[Problem] To provide a polarizing plate adhesive composition which can suppress warping (bending) of liquid crystal cells and which can form an adhesive layer with excellent durability. [Solution] This adhesive composition for a polarizing plate contains (A) a (meth)acrylic copolymer which is obtained by copolymerizing a (meth)acrylate alkyl ester with a 4-18 carbons in an alkyl group and a monomer component containing a polymerizable macromonomer, and which has a branching degree of 0.55 or less, measured by a gel permeation chromatography / multi-angle light scattering (GPC-MALS) detector, and is characterized in that the gel fraction of the adhesive formed from the aforementioned composition is 30 mass% or less.
