Document Type and Number:
WIPO Patent Application WO/2018/056710
Kind Code:
A1
Abstract:
The present invention provides an optical transparent adhesive composition, an optical transparent adhesive film comprising the same, and a flat panel display device, the optical transparent adhesive composition comprising a photo-curable (meth)acrylate copolymer, a polydimethylsiloxane-based (meth)acrylate compound, and a photo-polymerization initiator, wherein the photo-curable (meth)acrylate copolymer comprises, relative to the total weight of constituent units contained in the copolymer, 95-99.9 wt% of a hydroxy group-containing acryl-based copolymer and 0.1-5 wt% of an isocyanate group-containing (meth)acrylate-based monomer and the hydroxy group-containing acryl-based copolymer and the isocyanate group-containing (meth)acrylate-based monomer form a urethane bond, and wherein the hydroxy group-containing acryl-based copolymer comprises, relative to the total weight of monomers contained in the copolymer, 50-98 wt% of a C1-C12 linear or branched chain alkyl (meth)acrylate monomer and 2-50 wt% of a hydroxy group-containing polymerizable monomer and the weight average molecular weight of the hydroxy group-containing acryl-based copolymer is 200,000 to 1,000,000.
