    Abstract: Preparation of an acyloxy-organyloxy-silane of formula (R )nSi(R )m (I) comprises reacting a silicon tetrahalide of formula SiX4 (II) with (a) an alkanol, alkenol, alkynol or cyclic hydroxyl compound of formula H-R (III) and (b) either a metal carboxylate of formula MR (IV) or an anhydride of formula Z-C(O)-O-C(O)-Z (V), where R = -O-Y; R = -O-C(=O)-Z; m, n = 1, 2 or 3 and n + m = 4; Y, Z = optionally halogen-substituted 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl or (CH2)p-A; p = 0-6; A = 3-20 membered hydrocarbon ring; X = fluorine, chlorine, bromine or iodine; and M = Group IA or IIA metal.

    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.
