Abstract

A process wherein a titanium pigment is dispersed in an aqueous medium by the action of a dispersing agent and agitation, a water-soluble magnesium salt and a water-soluble aluminium salt each in a proportion corresponding to 0.1 to 2 per cent. of MgO and Al2O3, respectively, calculated on the weight of the pigment, are added to the dispersion without causing the latter to flocculate, and the magnesium and aluminium are precipitated in the form of water-insoluble compounds on the pigment particles by means of a compound of alkaline reaction. The sulphates of magnesium and aluminium are specified soluble salts, sodium hydroxide, sodium hexametaphosphate and trisodium phosphate specified dispersing agents and sodium hydroxide or carbonate are specified as compounds of alkaline reaction. A water soluble titanium salt may be added to the dispersion in a proportion corresponding to not more than 2 per cent. TiO2, and precipitated together with the magnesium and aluminium compounds. U.S.A. Specifications 1,368,392 and 2,378,790 are referred to.
