<P>PROBLEM TO BE SOLVED: To provide a process for producing an adhesive optical film in which an adhesive layer laminated on at least one surface of an optical film through an anchor layer, the adhesive optical film being good in adhesion and excellent in crack durability at high temperatures. <P>SOLUTION: The process comprises a step of applying an anchor layer coating solution that comprises a mixed solvent containing water and an alcohol as the main components and a binder resin onto an optical film in such a manner that the thickness of the resulting coating before drying becomes ≤20 μm and then drying the resulting product under the drying conditions that fulfill both the requirements (1)-(2) to remove the mixed solvent, thereby forming an anchor layer: (1) the drying temperature (T) is 40-70°C; and (2) a value (T×H) produced by multiplying the drying temperature T (°C) by a drying time H (s) is 400-4,000. <P>COPYRIGHT: (C)2012,JPO&INPIT |
