MANUFACTURING METHOD OF OPTICAL FILM
Document Type and Number:
Japanese Patent JP2022038918
Kind Code:
A
Abstract:
To provide a manufacturing method for manufacturing an optical film assembled with a resin layer (A) formed from a resin involving a polymer including an alicyclic structure and having crystallinity and a resin layer (B) formed on the resin layer (A), while suppressing crack formation in the resin layer (B) during the manufacture.SOLUTION: A manufacturing method of an optical film includes, in this order, a step (I) of preparing a resin layer (A) formed from a first resin involving a polymer including an alicyclic structure and having crystallinity, a step (II) of applying crystallization treatment to the resin layer (A), and a step (III) of forming a resin layer (B) from a second resin on a surface of the resin layer (A).SELECTED DRAWING: None
