Abstract: To prepare especially bluish nacreous pigments, TiO2-coated mica pigments are treated with ammonia at from 750 to 850 DEG C with constant agitation. The optical layer thickness of the titanium dioxide (TiO2) coating is from 50 to 100 nm or from 300 to 340 nm.

Abstract: Lustre pigments based on coated, plateletlike, silicatic substrates wherein the coating comprises a layer consisting essentially of carbon and aluminium oxide, chromium oxide, serium oxide, zirconium oxide and/or antimony oxide are obtainable by applying carbon-containing compounds of the metals aluminium, chromium, serium, zirconium, antimony or mixtures of these compounds and, if desired, further carbon-containing compounds of the empirical formula (CH2O)n, in which n is from 1 to 6 for one monomer unit, to the substrate particles and then thermally decomposing the carbon-containing compounds on the surface of the substrate particles under oxygen-excluding conditions.

Abstract: Glossy pigments consist of a carrier on a coloured organic lamellar colour pigment having film-like coatings of metal oxides applied thereto. The coatings are reacted in the gas phase by reaction of the corresponding metal compounds with a reaction component which reacts with these compounds to give metal oxides. The glossy pigments having high colouring power are used for colouring paints, plastics, cosmetics and printing inks.

Abstract: The novel carriers consist of steel cores which have an iron oxide- containing coating of the formula (FeO)x . Fe2O3 where x = 0.1 - 1. The carriers are stable and effective over long cycle times (6 .10 prints). … The carriers are obtained by treating steel cores (steel spheres) with defined small amounts of sulphuric acid of defined concentration, partial oxidation of the treated cores and drying at 60-150 DEG C at

Abstract: Bi vanadate pigments or pigments contg. Bi vanadate are coated with hardly soluble inorganic Fe cpds. (I). Pref. (I) are used in amts. of 0.001-2.0, pref. 0.05-0.5 wt.% w.r.t. the pigment. The pigments are produced by sepg. them from a suspension in an aq. Fe salt soln. and drying. The Fe salt is Fe2(SO4)3, Fe(NO3)3 or FeCl3. USE/ADVANTAGE - For pigmenting paints, printing inks and plastics. The (I) coating greatly reduced the photochromic effect. In an example, a suspension of 80 g pigment with the compsn. BiVO4.0.75 Bi2MoO6 and 120 g water was ball milled for 60 min. at 1200 rpm (A) without additive or with addn. of (B) 11.4 g Fe(NO3)3.9H2O or 6.8 g Fe2(SO4)3 in dissolved form. The suspension was filtered, washed and dried, giving a pigment contg. (A) 0.003, (B) 0.05, (C) 0.02 wt.% Fe. Paint contg. 20 g pigment in 80 g alkyl-melamine resin was sprayed onto sheet metal and half the sheet was exposed to a 1000 W lamp, 50 cm away, for 1 h. The difference in colour between the exposed and unexposed areas was (A) 2.2, (B) 1.1, (C) 0.7 immediately after exposure and (A) 1.0, (B) 0.2, (C) 0.1, 24 h after exposure.

Abstract: A plateletlike two-phase pigment which has a core with a hematite structure of the composition AlxFe2-xO3 where x is from 0.02 to 0.5, and an outer layer with a spinal structure of the composition AlyFe3-yO4+z where y is from 0.03 to 0.75 and z is from 0 to 0.5, can be prepared by a hydrothermal treatment of plateletlike AlxFe2-xO3 pigments (x from 0.02 to 0.5) in the presence of a reducing agent dissolved in the aqueous phase.
