Abstract:
1. A method for production of an adhesive optical film comprising an optical film, an anchor layer, and a pressure-sensitive adhesive layer placed on at least one side of the optical film with the anchor layer interposed therebetween, the method comprising the step of forming an anchor layer by applying an anchor layer-forming coating liquid to the optical film to form a coating with a thickness of 2 to 17 μm before drying, wherein the anchor layer-forming coating liquid contains a mixed solvent in which total content of water and an alcohol is 99% by weight or more, and a binder resin, and by drying the coating under drying conditions satisfying both of the following requirements: a content of a silane coupling agent in the pressure-sensitive adhesive layer is from 0.075 to about 1 part by weight based on 100 parts by weight of a base polymer of the pressure-sensitive adhesive layer.
