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: (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).
