ADHESIVE COMPOSITION FOR OPTICAL FILM, ADHESIVE LAYER FOR OPTICAL FILM AND METHOD FOR PRODUCING THE SAME, ADHESIVE OPTICAL FILM, AND IMAGE DISPLAY

摘要

An adhesive composition for optical film is provided to facilitate a process of peeling optical films from a liquid-crystal panel without the adhesive remained on the liquid-crystal panel and prevent an adhesive layer from being contaminated after an adhesive layer formation process. An adhesive composition for optical film comprises 45~99.99wt% of alkyl(meth)acrylate, 0.01~2wt% of monomer having tertiary amino groups, and 0.01~2wt% of peroxide acting as a cross-linking agent. The adhesive composition for optical film additionally contains 0.01~2 parts of an isocyanate-based cross-linking agent on a basis of 100 parts of (meth)acrylate polymer. A method for preparing an adhesive layer includes a step of coating the adhesive compositions on a film and curing the coated adhesive compositions at a temperature range of 70~160°C for 30-240 seconds.
