摘要： An inorganically after-treated TiO.sub.2 pigment with a coating of hydrophobicizing and hydrophilicizing organic substances, which pigment comprises more than about 95% by weight of TiO.sub.2, shows a loss on annealing of less than about 0.8% (after subtraction of the carbon content) and has a grindometer value smaller than about 30, corresponding to a value of more than about 5.6 on the Hegman scale, is produced by micronizing a mixture of an inorganically after-treated TiO.sub.2 pigment, an untreated TiO.sub.2 pigment and hydrophobicizing and hydrophilicizing organic substances, the after-treated pigment being employed in about 1 to 40% by weight of total TiO.sub.2 pigment and the hydrophobicing and hydrophilicizing substances being employed in about 0.3 to 5% by weight of TiO.sub.2 pigment. The pigments are readily dispersible which simplifies their use in pigmenting lacquers, plastics and paper.
