ABSTRACT:
Improved stable, fluid, aqueous dispersion compositions comprise a pigment, an alkali metal, alkaline earth metal or ammonium salt of a linear aliphatic substituted glycine such as a salt of ethylene diamine tetraacetic acid or nitrilo triacetic acid as a stabilizing agent, and water. The dispersion composition may additionally contain a lower alkanol such as methanol and/or a water soluble plasticizer such as propylene glycol. Coating compositions for use as a film coating for tablets and the like contain the above-described stable, fluid, aqueous dispersion composition, a water soluble plasticizer, a film coating resin, and water. The described fluid, aqueous dispersion compositions have been found to remain stable for extended periods exceeding six months.
