ABSTRACT:
Transparent pigment dispersions, having long term storage capabilities and which produce coatings having a rich clean color and excellent transparency are produced by first dispersing the pigment in a resin solution under high speed, high shear, high impact conditions followed by completing the dispersion under conditions of maximized shear and minimized impact. Such pigment dispersions are useful in automotive paints, particularly "metallic" automotive paints.
