ACRYLATE BASED ADHESIVE COMPOSITION FOR OPTICAL USE, ACRYLATE BASED ADHESIVE SHEET FOR OPTICAL USE AND METHOD FOR SEPARATING OPTICAL COMPONENT USING THE SAME

摘要

PURPOSE: An acrylic adhesive composition is provided to have excellent optical performance and fixing performance of an optical member, to have excellent reworkability while suppressing fracture of an optical member. CONSTITUTION: An acrylic adhesive composition comprises a copolymer and a crosslinking agent. The content of the crosslinking agent is 0.5-5 parts by weight based on 100.0 parts by weight of the copolymer. The copolymer is obtained by polymerizing 1-10 parts by weight of alkyl(meth)acrylate(the alkyl is C16-C22 linear alkyl group), 70-98 parts by weight of alkyl(meth)acrylate(the alkyl is C1-12 alkyl group), and 1-20 parts by weight of a polar monomer. The optical acrylic adhesive sheet has laminated adhesive layers. The adhesive layer comprises the copolymer crosslinked by a crosslinking agent.
