Abstract: In the process for manufacturing a light-resisting titanium dioxide pigment suitable for matting artificial fibers, by adding to a suspension of titanium dioxide pigment some water-soluble vanadium compound plus possibly a compound of aluminum, silicon and/or, phosphorus, which are precipitated onto the surface of the titanium dioxide particles, whereafter the suspension is filtered, washed, thermally dried, and ground, the thermal drying and the grinding are carried out at such a low temperature that the pigment temperature at no stage rises above 300.degree.C and for such a short period that the vanadium remains on the surface of the titanium dioxide pigment particles without being substantially calcinated into the particles, which consequently remain white.
