ABSTRACT:
A colored metallic pigment composition includes metallic particles which have been treated with a mixture of pigment particles and wax. A polymeric shell is formed on the treated metal particles by means of an organometallic coupling agent. The coupling agent includes a readily-hydrolyzable group which is capable of binding to the metal particle surface, and a relatively non-hydrolyzable group which serves as a binding site for the polymeric shell.
