Document Type and Number:
WIPO Patent Application WO/2016/129353
Kind Code:
A1
Abstract:
Provided is an adhesive composition for a polarizing plate, whereby an adhesive layer having excellent durability can be formed which is also capable of suppressing warping (bending) of a liquid crystal cell. The present invention relates to an adhesive composition for a polarizing plate, containing (A) a (meth)acrylic copolymer obtained by copolymerizing, through use of an organic peroxide-based initiator (a5), a copolymerizing component including (a1) a (meth)acrylate having a hydroxyl group, (a2) a polymerizable macromonomer, and (a3) at least one of an alkyl (meth)acrylate, an alkoxyalkyl (meth)acrylate, an alkoxypolyalkylene glycol mono(meth)acrylate, and a (meth)acrylate containing an alicyclic group or an aromatic ring, the branching degree of the adhesive composition as measured by gel permeation chromatography/a multi-angle laser light scattering detector (GPC-MALS) being 0.55 or less, the gel fraction of an adhesive formed by the composition being 54% by mass or less in the adhesive composition for a polarizing plate.
