Dispersao of blood cells of a first aqueous phase in a second aqueous phase continues, the treated article with the same, and process for preparing such dispersao

摘要

A method of producing dispersion in an aqueous medium of aqueous globules larger than the colloidal dimension and resistant to shear without subdividing, the phases being insoluble or immiscible in one another through interaction of the colloidal ionic reactants of opposite charge, preferably macromolecular polyelectrolytes, present in different phases. Optionally the globules may be separated from the medium and dried as discrete particles. When the aqueous globules differ in colour the compositions are useful in producing multicolour coatings, ceramic glazes and fibrous webs. Thus the dispersions may be applied to a surface to impart either a first decorative appearance, in which the globules appear in uniform spaced relationship with each other, relatively independently of method of application, the medium being clear or translucent, or a second decorative appearance, which varies according to the method of application, when the medium also is coloured, and different in colour from the globules, such that when applied by brush or roller a streaked or mottled appearance results.
