Document Type and Number:
WIPO Patent Application WO/2020/166682
Kind Code:
A1
Abstract:
This optical film contains a methacrylic resin and rubber particles. The methacrylic resin contains a structural unit derived from methyl methacrylate, and a structural unit derived from a co-polymerization monomer, other than the methyl methacrylate, that is co-polymerizable therewith. The structural unit derived from the co-polymerization monomer contains a structural unit derived from a specific co-polymerization monomer having a movable volume represented by formula (1) of 0.5 to 3.6. Formula (1): movable volume = monomer hard sphere volume/monomer molecular weight
