光学フィルム
Document Type and Number:
Japanese Patent JP6930100
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical film that has high solvent resistance and transparency and can sufficiently suppress punching failures such as cracks when the film is made thin.SOLUTION: The optical film comprises a cycloolefin-based resin and a copolymer resin having a structural unit derived from a styrene-based monomer and a structural unit derived from a fluorene-based monomer. The cycloolefin-based resin has a polar group; and the structural unit derived from a styrene-based monomer of the copolymer resin has a proton-donating group. The proportion of the copolymer resin relative to the total mass of the cycloolefin-based resin and the copolymer resin is 5 mass% or more and 95 mass% or less.SELECTED DRAWING: None
