Colored metallic pigment, process for producing the same, and coating composition and cosmetic preparation containing said colored metallic pigment

Abstract

This invention provides a colored metallic pigment, which can develop a variety of colors and varied interference colors while maintaining good lightfastness, weatherfastness and hiding power, a process for producing the same, a coating composition containing the colored metallic pigment and capable of providing a coating film having excellent finished appearance, and a cosmetic preparation containing the colored metallic pigment, having excellent hiding power, and capable of providing sharp hue. The colored metallic pigment comprises at least a metallic pigment, an amorphous silicon oxide film layer provided on the surface of the metallic pigment, a metal layer provided on the surface of the amorphous silicon oxide film layer, and metallic particles provided on the surface of the metal layer. The metallic particles are provided so as to directly cover a part of the surface of the metal layer. In the colored metallic pigment, the metal layer preferably comprises at least one metal selected from Sn, Pd, Pt and Au. The metallic particle preferably comprises at least one metal selected from Cu, Ni and Ag.
