More Information
Summary:Provided is a cellulose acylate composition containing cellulose acylate particles and metal compound-containing particles. The total degree of substitution of the cellulose acylate is from 0.7 to 2.9. The metal compound is one or more types of compounds selected from an alkali metal compound and an alkaline earth metal compound. The composition is produced by adding one or more types of metal compounds selected from an alkali metal compound and an alkaline earth metal compound during and/or after removing a water-soluble polymer from a dispersion containing, as a dispersoid, cellulose acylate impregnated with a plasticizer to form cellulose acylate particles.
