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 lustrous pigment consisting of a no. of coatings on a metallic platelet substrate has the following coatings: (A) a colourless coating of Refractive Index (RI) n = 1.8 or below; (B) a selectively - absorbing coating of RI n = 2.0 or above; and opt. also (C) an outer colourless or selectively - absorbing coating differing from the underlying (B) coating. Also claimed is prodn. of the pigment by successively coating the substrate with the coatings by gas phase decompsn. of volatile metal cpds. in presence of O2 and/or steam or by hydrolytic decompsn. of organometallic cpds.

Abstract: Colloidal palladium for hydrogenating olefins, acetylene, dienes and (un)saturated nitriles consists of palladium clusters having an average particle size of 0.2-2.0 nm. At least 80% of the palladium clusters have a particle diameter which deviates not more than 0.2 nm from the average particle diameter. The clusters have protective ligands on the surface. Independent claims are also included for: (1) production of a palladium colloidal solution by reacting a palladium salt with a reductant made of 4-30 C alcohol, and a protective ligand of phosphane and/or aromatic nitrogen compound at 0-300o C; (2) production of colloidal palladium comprising forming the above palladium colloidal solution, precipitating the colloidal palladium by adding a hydrocarbon solvent, removing the colloidal palladium, and drying; and (3) production of a palladium-containing heterogeneous catalyst by forming the palladium solution as above, impregnating a carrier selected from alumina, silicon dioxide, zirconium dioxide, titanium dioxide, carbon, zeolite and silicate.

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).
