ABSTRACT:
This invention relates to a process for treatment of pigments and the compositions of treated pigments using the disclosed process. Particularly, this invention describes a process for producing non-dusty, free flowing, granular pigment materials in which the pigment is treated by a water-dissipatable polyester. The treated pigment materials generally exhibit high dispersibility in water and polar solvent systems. Dispersions of such materials provide film-forming characteristics, water-resistivity and excellent adhesion when applied to the skin. The pigment materials prepared by the disclosed process are suitable for incorporation in paints, inks, cosmetic bases, liquid make-ups or other cosmetic preparations such as mascara.
