Zusammenfassung: | An inorganic red pigment is provided which pigment comprises titanium oxide, tin oxide, zinc oxide, and tungsten oxide, wherein the molar ratios of the oxides correspond to a composition of formula (TiO2)a(SnOx)b(ZnO)c(WO3)d (I), wherein SnOx comprises SnO and SnO2 in a molar ratio of SnO:SnO2 of from 70:30 to 100:0; 0.8 a 3.0; 0.3 b 2.0; 0.3 c 1.3; and 0.01 d 0.8. Optionally, SiO2, other metal oxides or metal sulfides may be present. The inorganic pigment may be used as colorant in various applications. |
