Abstract: Goniochromatic gloss pigment based on multi-layered, disc-shaped, metallic substrates which have ≥ 1 layered packet consisting of (A) a layer consisting essentially of silicon dioxide, hydrous silicon dioxide, aluminium oxide and/or hydrous aluminium oxide and (B) a non-selectively absorbing silicon-contg. layer which is ≥ partially transparent to visible light and opt. also (C) an outer layer which consists essentially of colourless or selectively absorbing metal oxide. Also claimed are gloss pigment mixts. consisting of the gloss pigments above and multi-layered silicate discs, and a process for the prodn. of the gloss pigments.

Abstract: (A) Prepn. of blue-shade gloss pigments is obtd. by treatment of silicatic flakes which are coated with titanium dioxide (the titanium dioxide coating having a geometric layer thickness of 10-60 nm) with a reducing gas mixt. (which contains a vaporised organic cpd. and ammonia) at 800-900 degrees C. (B) Blue-shade gloss pigment is based on silicatic flakes which comprise a reduced titanium dioxide and has a geometric layer thickness of 10-60 nm and a CIELAB colour value -2 ≤ a* ≤ b* ≤ -20 (measurement angle 20 degrees ,'standard light type'D65).

Abstract: The invention relates to a method of passivating metal pigments with respect to compounds containing hydroxyl groups, which is characterized in that the metal pigments are treated in the gas phase with passivating compounds. The procedure of the invention enables highly effective passivation to be achieved simply.

Abstract: Lustre pigments based on coated, plateletlike, silicatic substrates wherein the coating comprises a layer consisting essentially of carbon and aluminium oxide, chromium oxide, serium oxide, zirconium oxide and/or antimony oxide are obtainable by applying carbon-containing compounds of the metals aluminium, chromium, serium, zirconium, antimony or mixtures of these compounds and, if desired, further carbon-containing compounds of the empirical formula (CH2O)n, in which n is from 1 to 6 for one monomer unit, to the substrate particles and then thermally decomposing the carbon-containing compounds on the surface of the substrate particles under oxygen-excluding conditions.

Abstract: Glossy pigments consist of a carrier on a coloured organic lamellar colour pigment having film-like coatings of metal oxides applied thereto. The coatings are reacted in the gas phase by reaction of the corresponding metal compounds with a reaction component which reacts with these compounds to give metal oxides. The glossy pigments having high colouring power are used for colouring paints, plastics, cosmetics and printing inks.

Abstract: Preparation of transparent yellow iron oxide pigments by precipitation of iron(II) hydroxide by addition of an inorganic base to an iron(II) salt solution and subsequent oxidation to FeOOH, in which a) an aqueous iron(II) salt solution having a molarity of at least 0.5 is first admixed at from 25 to 45@C in the presence of dissolved phosphates and, if desired, zinc salts with sufficient base for from 50 to 70% of the iron(II) ions used to be precipitated as hydroxide, then oxidising gas is passed through the mixture obtained until the pH has dropped to a value
