Water-soluble cellulose acetate-based resin composition of the present invention includes a cellulose acetate total degree of acetyl substitution is 0.4-1.6 (A1), a polyvinyl alcohol saponification degree is not less than 50 mol% (B) including. Total degree of acetyl substitution of the cellulose acetate (A1) is preferably 0.6 to 0.9, saponification degree of the polyvinyl alcohol (B) is preferably 90 mol% or more. According to a first aspect of the water-soluble cellulose acetate-based resin composition of the present invention, another component is compatible to form a transparent resin composition, film low oxygen permeability and water vapor containing the resin composition indicates transparency, excellent function of protecting the active ingredients from oxidation and humidity, are very suitable as a base component of the coating layer of the coated preparation.
