2123407 9310190 PCTABS00022 A method of making synthetic color pigments comprises synthesizing monodispersed colloidal core particles (12) by precipitation from a solution and applying dye material (14) to the core particles either by adsorption directly into the core particles or by adsorption or incorporation into alumina fixation shells (16) at the surfaces of the core particles. Additional functional shells (18) may be applied to the dyed core particles for various reasons. The pigments are useful for the coloration of various media such as printing inks and paint compositions.
