Optischer Film

Disclosed is an optical film characterized by containing 0.001-10 parts by mass of an ultraviolet absorbent represented by general formula (1) per 100 parts by mass of a cellulose ester. (In the formula, n represents an integer of 1-4; when n is 1, R represents an alkyl group having 3-30 carbon atom...

More Information
Summary:Disclosed is an optical film characterized by containing 0.001-10 parts by mass of an ultraviolet absorbent represented by general formula (1) per 100 parts by mass of a cellulose ester. (In the formula, n represents an integer of 1-4; when n is 1, R represents an alkyl group having 3-30 carbon atoms, and when n is 2-4, R represents a residue obtained by removing a carboxylic acid group from an aliphatic or aromatic polybasic acid having 1-34 carbon atoms; and R1, R2, R3 and R4 independently represent a hydrogen atom or an alkyl group having 1-4 carbon atoms.)
