Title:
METHOD FOR PRODUCING RESIN FILM-EQUIPPED OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/115613
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a resin film-equipped optical member that is obtained by adhering a resin film to an optical member by using an adhesive layer, and exhibits favorable adhesion between the adhesive layer and the optical member. [Solution] A method for producing a resin film-equipped optical member that involves: a coating step for forming a coating layer by coating a longitudinally oriented resin film with an adhesive composition; a drying step for obtaining a resin film having an adhesive layer by drying the coating layer, by introducing the coated film to a drying means while continuously transporting said film; a smoothing treatment step for continuously transporting the resin film having the adhesive layer while pressing a mirror surface mold against the outer surface of the adhesive layer; and an adhesion step for continuing to continuously transport the smoothed film, layering a longitudinally oriented optical member on the outer surface of the adhesive layer, and applying pressure to this layered body from above and below.
