  • Surface-treated color pigment, colored substrate particles and production process thereof
    Patent number: 6022911
    Abstract: Colored substrate particles which are mainly used in metallic finish of automobiles, domestic electrical articles, tools and the like, decorative finish of plastics, printing ink and the like are disclosed herein. According to the present invention, adhesive property of a color pigment to substrate particles is improved by coating the surface of the color pigment with a specific surface-treatment agent. The colored substrate particles are preferably coated with a polymer polymerized by in situ polymerization, thereby the adhesion of the color pigment to the substrate particles can be further improved.
