ABSTRACT:
A coloring pearlescent flake pigment capable of providing pearl-like luster caused by interference color and a vivid color caused by a tar color is provided as a new material which contributes to the diversification of cosmetics and paints thanks to its powdery smoothness and the visual effect as well as covering protection effect in an application layer. The coloring pearlescent flake pigment having a double coating layer which is formed on inorganic flake-like particles and which is composed of a high-refraction-index metal oxide (e.g., titanium dioxide) and a hydrotalcite-like coloring composition is produced by the following process: In an aqueous suspension containing inorganic flake-like particles coated with a high-refraction-index metal oxide, a soluble anionic dye, a plurality of soluble metallic salts which are the raw materials of a double hydroxide, and a neutralizing base including urea are allowed to react, so that a hydrotalcite-like coloring composition precipitates on the inorganic flake-like particles.
