摘要

PROBLEM TO BE SOLVED: To obtain a bright and deep-colored color flake pigment innoxious for human bodies in order to provide a new material for diversifying coating or functionalizing a cosmetic. SOLUTION: This color flake pigment has a coating layer of a hydrotalcite type coloring composition on the surfaces of inorganic flaky particles. The color flake pigment is produced by reacting a soluble anionic coloring matter with plural soluble metal salts to be a raw material for a double hydroxide and a base for neutralization in an aqueous suspension containing the inorganic flaky particles and depositing and producing the hydrotalcite type coloring composition on the surfaces of the inorganic flaky particles.
