Title:
OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2022/202337
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical film which has excellent low moisture permeability and is suitable for a protective film for a polarizing plate. An optical film 10 according to the present invention has a lamination structure in which a resin layer 1 is laminated on one surface of a light-transmitting substrate 2. The resin layer 1 is formed of a cured product of a curable composition containing at least one polymerizable compound selected from the group consisting of a monomer having a polymerizable functional group and an oligomer having a polymerizable functional group. The product (T×M1) of the thickness T [μm] of the resin layer 1 and the moisture permeability M1 [g/m2∙24h] of the optical film in an environment of a temperature of 40ºC and a relative humidity of 92% is at most 1,500.
