ABSTRACT:
A dispersion of a colored high-molecular weight particulate material is prepared by a) mixing a pigment with an aqueous emulsion of a resin to form a dispersion of the pigment within the emulsion; b) combining the dispersion with particles of polyvinyl chloride containing a plasticizer to form a mixture; and c) adding a metal salt to the mixture to cause the resin to coagulate onto the particles of the polyvinyl chloride. A film comprising the resin and the pigment is formed on the particles of the polyvinyl chloride.
