METAL CATIONS AND METAL EFFECT PIGMENTS COMPRISING ANIONS CONTAINING PHOSPHORUS AND/OR SULPHUR, METHOD FOR PRODUCING SAID METAL EFFECT PIGMENTS AND USE THEREOF

The invention relates to a metallic effect pigment selected from platelet-shaped aluminum, platelet-shaped metallic pigments having a copper fraction of 60% to 100% by weight, and mixtures thereof, having a coating of silicon oxide SiOx, where x is a number from 1 to 2, where the coated metallic effect pigment comprises metal cations and phosphorus- and/or sulfur-containing anions present independently of one another on the metallic effect pigment surface and/or in the silicon oxide layer SiOx, and the element ratio in atomic fractions of metal cation MC and phosphorus P and/or sulfur S to silicon Si is defined by formulae (I) and (II): 100%×(MC+P)/Si (I) and/or 100%×(MC+S)/Si (II) and being in total in a range from 0.5% to 35%. The invention further relates to the coated metallic effect pigments producible via the method of the invention, and to the use thereof.
