Abstract

PURPOSE: In an aqueous slurry of ultramarine and an inorganic pigment other than metal pigments, to prepare title composition, by forming a silica sol from an alkali silicate and an organic compound, and depositing a fine, amorphous silica on the pigment particle.
CONSTITUTION: In a slurry of ultramarine (A) and an inorganic pigment (B) other than metal pigments, an alkali silicate (C) is reacted with at least one organic compound (D) capable of forming a silica gel by the reaction with (C), to form a silica sol, and a fine amorphous silica is deposited on the surface of the inorganic pigment particle. Whereby a stable, inorganic pigment is prepared. Where (B) is a pigment which has been treated with a hot aqueous alkali solution and coated with fine hydroxides of metals such as Zr, Al and Ti. The formation of the silica sol is carried out at ≥60°C and at pH9W11, under normal pressure.
