The invention relates to pigment preparations containing a) solid compounds from the groups of oxides of titanium, zinc, tin, tungsten, molybdenum, nickel, bismuth, cerium, indium, hafnium, iron and/or silicon carbide, zinc sulfide, barium titanate, calcium titanate and/or silicon and/or solid silicon compounds in which silicon is available in stoichiometric surplus, with primary particles having a mean diameter of 500 nm, and b) at least one coloring agent which distinguishes itself from the solid compounds named under a). The inventive pigment preparations are characterized by a good resistance to light of the substrates colored with said preparations.
L'invention concerne des préparations pigmentées contenant a) des composés solides du groupe des oxydes de titane, de zinc, d'étain, de wolfram, de molybdène, de nickel, de bismuth, de cérium, d'indium, d'hafnium, de fer et/ou de carbure de silicium, de sulfure de zinc, de titanate de baryum, de titanate de calcium et/ou de silicium et/ou de composés solides de silicium, dans lesquels le silicium est en excédent stoechiométrique, le diamètre moyen des particules primaires étant < 500 nm, et b) au moins un colorant distinct des composés solides cités en a). Ces préparations pigmentées sont caractérisées par la bonne résistance à la lumière des supports colorés avec ces préparations.
