Scale-like pigment coated with ultrafine barium sulfate and its production

摘要

Disclosed are a flaky pigment in which the surfaces of fine flaky grains, as a base of pigment, have been coated with ultra-fine barium sulfate grains having a mean grain size of 0.1 mu m or less, by the use of: (a) an aqueous solution containing a complexing agent capable of forming a complex compound with barium ion, as dissolved therein; (b) an aqueous solution containing a water-soluble barium compound as dissolved therein; and (c) an aqueous solution containing sulfate ion; and a method of preparing the flaky pigment; and use of it in pigment coloration of cosmetics, top coats for cars, plastics, printing inks, domestic electric appliances, coating materials and coating paints for building materials.
