摘要：Improved stable, fluid, aqueous dispersion compositions comprise a pigment, an alkali metal, alkaline earth metal or am- monium 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 wa- ter soluble plasticizes such as propylene glycol. Coating compositions for u se as a film coating for tablets and the like contain the above-described stable, fluid, aqueous dispersion composition, a water solub le plasticizes, a film coating resin, and water. The de- scribed fluid, aqueous dispersion compositions have been found to remain stable for extended periods exceeding six months.
