A CLEANING METHOD OF A METAL MOLD FOR PRODUCING AN OPTICAL FILM AND A PROCESS FOR PRODUCING AN ANTIGLARE FILM

摘要

PURPOSE: A cleaning method of a roll mold for optical film production and a manufacturing method of antiglare film are provided to make a high quality of film without damage. CONSTITUTION: A cleaning method of a roll mold for optical film production is as follows. The roll mold with mold contamination materials is performed by ultrasonic waves in a basic solution(1) more than pH 10 in 30°C~70°C. The mold contamination material is photo-crosslinkable polymer resin. The basic solution contains water-soluble organic solvent. The content of water-soluble organic solvent in the basic solution is 70 weight% or less about the total amount of basic solution. A roll mold has concavo-convex on surface in order to produce an antiglare film.
