Document Type and Number:
WIPO Patent Application WO/2018/048272
Kind Code:
A2
Abstract:
The present invention provides an optical transparent adhesive composition characterized in that a photocurable (meth)acrylate copolymer contains 95 to 99.9% by weight of a hydroxy group-containing acrylic copolymer and 0.1 to 5% by weight of an isocyanate group-containing (meth)acrylate monomer, with respect to the total weight of the constitutional units contained in the copolymer, wherein the hydroxy group-containing acrylic copolymer and the isocyanate group-containing (meth)acrylate monomer form a urethane bond, and wherein the hydroxy group-containing acrylic copolymer contains 50 to 89% by weight of C4-C12 linear or branched alkyl acrylate monomers having a glass transition temperature of -70 to -50℃, and 11 to 50% by weight of hydroxy C4-C6 linear or branched alkyl acrylate monomers having a glass transition temperature of -60 to -40℃, with respect to the total weight of the monomers contained in the copolymer, and has a weight average molecular weight of 200,000 to 1,000,000.
