Summary: | The invention relates to pigment based on (multiple) coated platelet-shaped substrates comprising an outer layer which is obtained by treatment with a metal oxide/hydroxide and then a phosphate ester, or phosphonate, or a salt thereof, with the proviso that the phosphate ester, or phosphonate do not contain fluorine, to a method for producing said pigments and the use thereof. The outer layer provides a very good photo-stabilisation of the TiO2coated platelet-shaped substrates, such as mica, combined with a good water resistance and an anti-yellowing performance. |
