Adhesives, an optical member for pressure-sensitive adhesive, pressure-sensitive adhesive layer-carrying optical member, an image display device, an active energy ray-curable pressure-sensitive adhesive composition

摘要

PROBLEM TO BE SOLVED: To provide an adhesive agent excellent in reworking performance (relaminating property), durability and optical properties (light leakage-proof performance) when an optical element such as a polarizing plate, and a glass substrate or the like are laminated, particularly to provide an adhesive agent for an optical element.;SOLUTION: The adhesive agent is obtained by curing, by an active energy ray and/or heat, an adhesive agent composition [I] including an acrylic resin (A1) containing a hydroxyl group on the side chain, an acrylic resin (A2) containing a carboxyl group on the side chain, and an aromatic compound (B) containing one ethylenically unsaturated group.;COPYRIGHT: (C)2012,JPO&INPIT
