Abstract: Bismuth vanadate pigments IBi.sub.x Fe.sub.y E.sub.v V.sub.(1-w) P.sub.w O.sub.z Iwith the following meanings of the variables:E denotes calcium, zinc, cerium, praseodymium, and/or silicon;x is a value from 0.8 to 1.2;y is greater than 0 to 0.1 when v is greater than 0 or is greater than or equal to 0.035 to 0.1 when v is equal to 0;v is greater than or equal to 0 to 0.2;w is greater than 0 to 0.1;z denotes the number of oxygen atoms required to satisfy the valence requirements of the cations.and the preparation and use of said pigments for dyeing coating compositions, printing inks, and plastics.

Abstract: Luster pigments based on multiply coated plateletlike silicatic substrates, obtainable by further coating substrates already coated with a first layer comprising a colorless or selectively absorbing metal oxidea) initially with a second, nonselectively absorbing layer consisting essentially of carbon, a metal or a metal oxide, andb) if desired subsequently with a third layer comprising colorless or selectively absorbing metal oxide, wherefor the carbon layer (step a) is applied by thermal decomposition of oxygen-containing hydrocarbons that for every two carbon atoms contain at least one oxygen atom, the metal layer (step a) is applied by gas phase decomposition of volatile compounds of these metals in an inert gas, and the metal oxide layer (step a and/or b) is applied by gas phase decomposition of volatile compounds of these metals in the presence of oxygen, water vapor or mixtures thereof to the substrates coated in case a) with a first metal oxide layer and in case b) additionally with a nonselectively ab

Abstract: Luster pigments based on coated plateletlike substrates comprising nitrogen-containing metal layers and if desired additionally one or more layers consisting essentially of colorless or selectively absorbing metal oxide, are prepared and used for coloring paints, inks, including printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations.

Abstract: Luster pigments comprise coated plateletlike substrates wherein the coating comprises a layer comprising bismuth vanadate.

Abstract: An essentially monoclinic bismuth vanadate of the formula Bi[V.sub.1-x P.sub.x)O.sub.4 ] where x is from 0 to 0.1 has a chroma of .gtoreq.85, a lightness of .gtoreq.80, a hue angle of from 89 to 95 and a photochromism with a .DELTA.E value of .ltoreq.2 under the CIELAB system.
