PURPOSE:An organic compound is introduced onto an inorganic powder by mechanochemical reaction, then an organic pigment is synthesized on the powder utilizing the organic compound introduced to produce the titled pigment with high resistances to water, solvents and high duration. CONSTITUTION:An organic compound such as a benzene derivative is introduced on the surface of inorganic powder by utilizing mechanochemical reaction between an inorganic powder such as silica, alumina or aluminum hydroxide and an organic compound such as 4-aminobenzoic acid or 4-aminonaphthoic acid, e.g., by a mechanical operation such as grinding. Then the resultant organic compound is used to synthesize a dye or pigment on the surface of the inorganic particles, thus giving the objective pigment. EFFECT:Appropriate selection of inorganic powders, their particle sizes and mechanical energy permits the production of a pigment with desired opacifying strength and particle sizes.
