| abstract |
Film-forming cellulose ester compositions containing at least one solvent and at least one phosphate as stripping aid, said phosphate being a mono- or di-C12-C20alkyl phosphate, the non-esterified hydroxyl group(s) of which is (are) in the free acid form. The invention also relates to a method of manufacturing cellulose ester film, comprising adding to cellulose ester, at least one solvent and at least one above defined phosphate, casting the resulting film-forming cellulose ester composition on a smooth casting surface, and stripping said cellulose ester composition in the form of a film. |
