摘要：
Ready-to-use water dispersible pigment compositions containing waer-insoluble, hydrophilic pigments are provided. The compositions comprise a stable dispersion of the pigment such as a porphyrin pigment, carmine, curcumin and a carotenoid in the form of bodies of an average size which is at the most 10 nullm is provided. The pigment bodies are dispersed without the use of a surface active substance in an aqueous phase comprising a hydrocolloid. The natural pigment compositions which are useful for coloring of food products and maceuticals do not migrate in the products and they are acid stable. The compositions are useful in coating compositions for tablets and dragees.
