ABSTRACT:
An inorganic pigment comprising a content of at least 0.1% by weight and at most 5% by weight of one or more polyorganosiloxanes, wherein the polyorganosiloxanes have viscosities of 10 to 100,000 mPa.s and a relative molecular weight of 500 to 500,000, have no reactive or crosslinking groups, contain at least one C.sub.9 -C.sub.25 Si-alkyl and/or one C.sub.9 -C.sub.25 Si-aryl group per molecule, the total content of these groups in the polyorganosiloxane being 7-70% by weight and the other organic radicals contained in the polyorganosiloxane having 1 to 8 carbon atoms. Such pigments can be used in lacquers, emulsion paints, plastics, toners, magnetic recording materials, building materials and enamels.
