Provided are a cellulose resin composition and cellulose resin film which are free from the problem of bleeding even when containing a plasticizer in a relatively large amount. The present invention relates to a cellulose resin composition obtained by adding (A) polyester plasticizer to a cellulose resin, wherein the aforementioned (A) polyester plasticizer is obtained by allowing a polybasic acid and a polyalcohol to react and 80 mol % or more of said polybasic acid is a succinic acid and an adipic acid. The present invention also relates to a cellulose resin film obtained from the cellulose-based resin composition.

Cellulose resin composition and cellulose resin film

Provided are a cellulose resin composition which can give a cellulose ester film free from the problems with bleeding and has excellent moisture permeability, even when containing a plasticizer in a relatively large amount, and a cellulose resin film which is obtained from the cellulose resin composition. The present invention relates to a cellulose resin composition obtained by adding (A) a polyester plasticizer to a cellulose resin. The aforementioned (A) polyester plasticizer is obtained from a polybasic acid, a glycol and a stopper, wherein 70 to 30 mol % of the aforementioned polybasic acid is a succinic acid and/or an adipic acid; 30 to 70 mol % of the aforementioned polybasic acid is at least one selected from a group consisting of a terephthalic acid, a phthalic acid and an isophthalic acid; the aforementioned glycol is at least one selected from a group consisting of an ethylene glycol, a 1,2-propylene glycol, a 1,3-butanediol and a 2-methyl-1,3-propanediol; the aforementioned stopper is an acetic acid and/or a benzoic acid; and the weight-average molecular weight is 600 to 2,000.
