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: Plateletlike pigments based on iron oxide and having a spinel structure of the composition: MnuAlvFe[3-(u+v)]-zO4-z, where u is from 0.01-0.09, v is from 0-0.3 and z is from 0-1. The pigments can be used for producing decorative coatings, in particular in paints, plastics, prints and cosmetics, for producing electromagnetic screens, as substrates for coatings and as pigments having magnetic properties.
