A manufacturing method of a UV cure adhesive development thing and the polarizing lens using this

Japanese Patent JP5989263

B2

The present invention relates to a UV curing adhesive composition, and a method for preparing a polarizing lens by using the same, and more specifically, to a UV curing adhesive composition for preparing a polarizing lens, comprising 50-80 parts by weight of a monofunctional monomer, 14-49 parts by weight of an oligomer, and 1-6 parts by weight of a photoinitiator, wherein the monofunctional monomer comprises at least one monomer selected from phenoxyethyl acrylate (POA), isobornyl acrylate (IBOA), N-vinyl caprolactam (NVC) and tetrahydrofuran acrylate (THFA), the oligomer is one of either an acrylic acrylate oligomer (product name: ELVACITE-4026, manufacturer: INEOS Co., Ltd.) or an acrylic acrylate oligomer (product name: ELVACITE-4054, manufacturer: INEOS Co., Ltd.), and the photoinitiator is 2,4,6-trimethylbenzoyl diphenylphosphine oxide (TPO). The present invention prevents a polarizing laminated film from being bent when annealing so as to remove residual deformation, and greatly improves workability when cutting the polarizing laminated film. In addition, the separation of a polycarbonate film, which is adhered to a polarizing sheet, from the polarizing sheet due to a long time use is prevented.
