Title:
PRESSURE-SENSITIVE ADHESIVE SHEET, PROCESS FOR PRODUCING SAME, AND PROCESS FOR PRODUCING OPTICAL MEMBER USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/117045
Kind Code:
A1
Abstract:
Disclosed are: a pressure-sensitive adhesive sheet which includes a pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer is a layer formed by curing a solvent-free curable resin composition by irradiation with actinic rays, the curable resin composition comprising a polyfunctional (meth)acrylate compound (C), a photopolymerization initiator, and a syrupy acrylic resin composition obtained by partially polymerizing, through bulk polymerization, a monomer composition comprising 50-85 mass% (meth)acrylic ester (A) having only one unsaturated double bond in the molecule and 15-50 mass% hydroxylated (meth)acrylic ester (B) having only one unsaturated double bond in the molecule, some of the (meth)acrylate compounds (A) and (B) remaining unreacted in the pressure-sensitive adhesive layer; a process for producing the pressure-sensitive adhesive sheet; and a process for producing an optical member using the pressure-sensitive adhesive sheet.
