    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: Solid pigment preparations comprising as essential constituents (A) from 60% to 95% by weight of at least one pigment, (B) from 2.5% to 35% by weight of at least one water-soluble surface-active additive based on polyurethanes and (C) from 2.5% to 35% by weight of at least one nonionic water-soluble surface-active additive (C1) based on polyethers and/or of an anionic water-soluble additive other than additives (B) which is based on polymers of ethylenically unsaturated carboxylic acids (C2), and also production and use of the pigment preparations for coloration of macromolecular organic and inorganic materials and also of plastics.
