    Abstract: PROBLEM TO BE SOLVED: To obtain a pigment for a spectrum from red-yellow to orange free from toxic metals and producible with an economical method by calcining a homogenous mixture of bismuth oxide and vanadium oxide and leading to vanadic acid bismuth having a specific composition containing additionally phosphorous in the form of phosphoric acid bismuth. SOLUTION: A vanadic acid bismuth pigment additionally containing phosphorous in the form of phosphoric acid bismuth in an amount of 0-0.5wt.%, expressed by the formula (Bi4 V2 O11 )1-x .(BiVO4 )x (0 =62 (measurement angle 45 deg., standard light D65). The pigment is obtained e.g. by calcining a homogenous mixture of bismuth oxide and vanadium oxide at 600-900 deg.C for 2-12hr, slowly cooling to the ambient temperature tanking at least 6-20hr down to about 200 deg.C and subsequently pulverizing the product.

Date Jun. 24, 1993Luster 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 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 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.
