摘要 |
A cellulose ester film comprises (a) an ultraviolet absorbent polymer having at least one of repeating units represented by formulae (1) and (2) and repeating units having ultraviolet absorbent structures represented by formulae (3), (4) and (5), (b) an ultraviolet absorbent polymer which is a copolymer of a repeating unit represented by the following formula (6), (7) or (19) with a monomer unit derived from another ethylenically unsaturated monomer, (c) an ultraviolet absorbent polymer which is a copolymer of a monomer represented by formula (8) with a monomer represented by formula (9), or (d) modified cellulose in which an ultraviolet absorbent structure bonds directly or through a spacer to a hydroxy group of cellulose or its derivative.
