  • Patent number: 5123963
    Abstract: A method for the formulation and preparation of a heterochromatic paint comprises reacting one or more base mediums containing an anionic cellulose thickener in emulsion with an inorganic salt of a heavy or trivalent metal contained in a reactive medium emulsion. The heterochromatic paint comprises an emulsion containing non-soluble precipitated color particles, and each of the base mediums are of a different color. The inorganic salt is used in an amount sufficient to form dispersed phase reaction products contained in a dispersing phase emulsion and consisting essentially of non-soluble precipitated color particles. The ratio of the dispersed phase to the dispersing phase in the heterochromatic paint is not greater than 0.4:1.
