PROBLEM TO BE SOLVED: To provide a cellulose-based resin composition that can produce a film excellent in optical characteristics; and to provide a film excellent in optical characteristics containing the cellulose-based resin.SOLUTION: A cellulose-based resin composition is obtained by formulating at least one selected from polyketone compounds expressed by general formula (I) in an amount of 0.1-20 pts.mass based on 100 pts.mass of a cellulose-based resin. In formula, Rrepresents an alkylene group, aromatic group, ketone diarylene group or oxydiarylene group; Xto Xeach independently represents H, a hydroxy group, alkyl group, alkoxy group, alkanoyloxy group or alkoxycarbonyl group. |
