    Abstract: Luster pigments consisting of flaky (plateletlike) metallic substrates with multiple coatings including A) a first, colourless or selectively absorbing layer (coating) of metal oxide, B) a second, non-selectively absorbing layer of carbon, metal and/or metal oxide, and C) if desired a third, colourless or selectively absorbing layer of metal oxide, and their production and use for colouring paints, printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations.

    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 oxide a) initially with a second, nonselectively absorbing layer consisting essentially of carbon, a metal or a metal oxide, and b) if desired subsequently with a third layer compris ing 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 absorbing layer a), and also specific pigments and preparation and use of the luster pigments for coloring paints, printing inks, plastics, decorative cosmetic preparations, glasses and ceramic products.

    Abstract: Goniochromatic lustrous pigments (G) based on metallic diskette substrates are coated with: (A) (hydrated) silica and/or (hydrated) alumina layer; (B) aluminium metallic layer allowing at least some visible light to pass through it; and (C) opt. outer layer of colourless or selectively absorbent metal oxide and/or one contg. phosphate, chromate and/or vanadate. Also claimed are the following : (i) lustrous pigment mixts. comprising (G) and silicate diskettes coated with a colourless or selectively absorbent metal oxide layer (A`), metallic aluminium layer (B`) through which visible light can pass and opt. outer layer (C`) of colourless or selectively absorbent metal oxide and/or one contg. phosphate, chromate and/or vanadate; (ii) prepn. of (G); and (iii) prepn. of aluminium-coated pigment diskettes by reacting volatile gaseous alkyl aluminium cpds. or aluminium hydride trialkylamine adducts in an inert atmos. in the presence of the diskettes. (C) contains (hydrated) SiO2, (hydrated) Al2O3, TiO2, ZrO2, Fe2O3 and / or Cr2O3. The substrates are coated only with (A) and (B). The metallic substrates comprise Al and are made by standard extrusion and grinding techniques. They may be coated with a ferromagnetic layer and/or passivated. AlH3 tri(1-4C alkyl)amine adducts or alkyl aluminium cpds. of the following formula are used to make Al-coated pigment plates: R aAlXb, where R = 1-4C alkyl, X = H or halogen; a = 1-3, and b = 0 - 2.
