摘要:
A water-dispersible, particulate film-forming composition is produced by blending a mixture of particles of water-soluble cellulose acetate; pigment particles, a plasticizer for the water-soluble cellulose acetate, and a surfactant. The composition is useful as a film-forming material for coating solid pharmaceutical forms.
