2124851 9311183 PCTABS00022 Inorganic material particles are dispersed in an aqueous medium with surface charge adjusting additives to give a moderately stable slurry or pigment grind. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to give the same performance as products including inorganic material dispersed with conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance properties with like levels of inorganic material.
