Abstract
The invention concerns to an anatase white pigment which is doped in compensatory mode with a trivalent cation selected from Al, Ga, In and Ce, and a further cation selected from the group consisting of a monovalent cation selected from Li, Na and K and a pentavalent cation selected from Sb and Nb, wherein the further cation is present in an amount of less than 1.5 mol% with respect to Ti in the base substanceTi02 pigments in the anatase modification with increased light and weather resistance, wherein the Ti02 pigments have advantages in respect of blue tint, low hardness and abrasiveness.
