Abstract: Pigments of flake substrate coated with calcium carbonate wherein the surface of the flake substrate is coated with fine particles of calcium carbonate. The pigment may be manufactured by a method where calcium carbonate in fine particles is separated out and coated on the surface of the flaky substrate by the reaction of a calcium salt with a carbonate in a suspension of the flake substrate. It can be used as an extender particularly for cosmetics exhibiting appropriate adhesion to skin, low luster and excellent wrinkle-hiding effect, prevention of unpleasant feel due to perspiration, sebum absorbing property, etc.
