Abstract
The invention relates to a titanium dioxide pigment mixture comprising a pigment having high greying stability (pigment type A) and a pigment having increased SiOand AlOcontent in flaky precipitation (pigment type B). Said mixture provides, for example in paper, a high level of opacity for sufficient greying stability. If necessary, the light-fastness of the paper can be further increased by means of known production-conditioned measures on pigment type B.
