Document Type and Number:
Japanese Patent JP6996552
Kind Code:
B2
Abstract:
The present invention relates to an optical film which is characterized by containing a cycloolefin resin, a retardation reducing agent which is formed from a cinnamic acid ester derivative-fumaric acid diester copolymer, and core-shell particles, and which is also characterized in that, with respect to the core-shell particles, the glass transition temperature of the polymer that constitutes the shell is higher than the glass transition temperature of the polymer that constitutes the core by 150°C to 290°C (inclusive). The present invention provides an optical film which has sufficient bondability, while having improved brittleness.
