Title:
OPTICAL FILM
Document Type and Number:
Japanese Patent JP2022149452
Kind Code:
A
Abstract:
To provide an optical film which is superior in terms of low moisture permeability and is suitable for a polarizing plate protection film.SOLUTION: An optical film 10 of the present invention has a laminated structure in which a resin layer 1 is laminated on one surface of a light transmissive base material 2. The resin layer 1 is formed of a cured product of a curable composition containing at least one polymerizable compound selected from a group consisting of monomers having polymerizable functional groups and oligomers having polymerizable functional groups. A product (T×M1) of thickness T [μm] of the resin layer 1 and moisture permeability M1 [g/m2 24h] of the optical film in an environment with temperature of 40°C and relative humidity of 92% is 1,500 or less.SELECTED DRAWING: Figure 1
