Process for production of adhesive optical film

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:
• (1) the drying temperature T is between 40° C. and 70° C.;
• and
• (2) the value (T×H) obtained by multiplying the drying temperature T (° C.) by the drying time H (seconds) satisfies the relation
• 500 ≦(T×H)≦2,900
• to remove the mixed solvent, and there is a time period of 10 seconds or less between applying the anchor layer-forming coating liquid to the optical film and starting the drying,
• 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.
