The optical film of this invention contains 0.001-10 mass parts of ultraviolet absorbers represented by following General formula (1) to 100 mass parts of cellulose esters, It is characterized by the above-mentioned. (Wherein n represents an integer of 1 to 4. When n is 1, R represents an alkyl group having 3 to 30 carbon atoms. When n is 2 to 4, R represents an aliphatic having 1 to 34 carbon atoms or The residue except the carboxylic acid group in an aromatic polybasic acid is shown, R < 1> , R < 2> , R < 3> and R < 4> show a hydrogen atom or a C1-C4 alkyl group each independently.) |
