  • Patent number: 4376654
    Abstract: The invention is a method of producing dispersions of aqueous globules in an aqueous medium. The aqueous phases are rendered insoluble or immiscible in one another by the presence in separate phases of colloidal ionic reactants, preferably macromolecular polyelectrolytes, which are opposite in charge. The dispersed globules are larger than colloidal dimensions, and may be as large as one-half inch or more in length. If desired, they can be separated from the continuous medium and dried as discrete particles. When one or more of the aqueous phases are different in color, the compositions are useful in producing multicolor coatings, ceramic glazes, and fibrous webs. The dispersion is unique in that each of the dispersed globules possesses such plasticity and coherence that it may be subjected to substantial shear without subdividing. The dispersion when the globules are colored may be applied to a desired surface to impart either a first or second decorative appearance thereto.
