Abstract
Official abstract text for this publication.
A method for production of an adhesive optical film comprises 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 20 μm or less before drying, wherein the anchor layer-forming coating liquid contains a mixed solvent composed mainly of water and an alcohol, 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 400≦( T×H )≦4,000 to remove the mixed solvent.
First claim
Opening claim text (preview).
The invention claimed is: 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-formin…
