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. |
