Abstract
Provided is a cellulose resin composition wherein roll contamination during processing and reduction in the productivity caused by roll contamination are inhibited. The cellulose resin composition is obtained by adding a polyester-based plasticizer to a cellulose resin, the cellulose resin composition being characterized in that the polyester-based plasticizer is produced from a polybasic acid, a polyhydric acid and, as required, a stopper, in which polyester-based plasticizer, components having a molecular weight of 430 or less are removed to an amount of 5 wt % or less.
