    摘要: The invention relates to a method of forming (rutile) titanium dioxide-coated platelet-like pigments in which hydrous titanium dioxide is deposited on platelet-like particles followed by calcining, comprising (a) effecting the titanium deposit in the presence of an α-hydroxy carboxylic acid, especially glycolic acid, or oxalic acid, and an amino acid, especially glycine, alanine, valine, aspartic acid (α-, β- and γ-form); or an amino acid; to the pigments obtained by the method and the use thereof. The method can work in the absence of exogenous metal and Ti(III). The rutile TiO2-coated substrate of the present invention has at least the same advantages and characteristics of a tin containing product which includes luster, color, color homogeneity and few small particle formation during manufacture.

    摘要: The present invention relates to platelet-shaped pigments that comprise a layer obtained by calcining TiO2/SiOy or TiO2/metal, especially TiO2/AI (0.03≦y≦1.95, especially 0.03≦y≦1.8, more especially 0.70≦y≦1.8), and to the use thereof in paints, textiles, ink-jet printing, cosmetics, coatings, plastics, printing inks, in glazes for ceramics and glass, and in security printing. The pigments according to the invention are distinguished by a high gloss and a very uniform thickness, as a result of which very high color purity and color strength are obtained.
