Document Type and Number:
WIPO Patent Application WO/2019/188593
Kind Code:
A1
Abstract:
This method for manufacturing an optical film comprises: a step for applying and drying an active energy ray curable resin composition on a surface reverse to a surface having a knurling portion with a height of 2-10 μm of a continuous film support having the knurling portion along each of both ends in a width direction, thereby forming a coating film; and a step for winding the continuous film support on which the coating film is formed around a temperature regulating roll with the surface having the knurling portion being brought into contact therewith, and irradiating the coating film on the temperature regulating roll with an active energy ray.
