    Abstract: PCT No. PCT/EP92/02793 Sec. 371 Date Jun. 13, 1994 Sec. 102(e) Date Jun. 13, 1994 PCT Filed Dec. 3, 1992 PCT Pub. No. WO93/12182 PCT Pub. Date Jun. 24, 1993Luster pigments based on multiply coated plateletlike silicatic substrates, obtainable by further coating substrates already coated with a first layer comprising a colorless or selectively absorbing metal oxide a) initially with a second, nonselectively absorbing layer consisting essentially of carbon, a metal or a metal oxide, and b) if desired subsequently with a third layer comprising colorless or selectively absorbing metal oxide, wherefor the carbon layer (step a) is applied by thermal decomposition of oxygen-containing hydrocarbons that for every two carbon atoms contain at least one oxygen atom, the metal layer (step a) is applied by gas phase decomposition of volatile compounds of these metals in an inert gas, and the metal oxide layer (step a and/or b) is applied by gas phase decomposition of volatile compounds of these metals in the presence of oxygen, water vapor or mixtures thereof to the substrates coated in case a) with a first metal oxide layer and in case b) additionally with a nonselectively absorbing layer a), and also specific pigments and preparation and use of the luster pigments for coloring paints, printing inks, plastics, decorative cosmetic preparations, glasses and ceramic products.

    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.

    Abstract: Particles (I) which are suitable as carriers for electrophotography consist of a) a magnetic core and b) a shell of alumina, chromium oxide, molybdenum oxide, tungsten oxide, silica, tin oxide or zirconium oxide or a mixture thereof and particles (II) consist of a) a magnetic core and b) a shell of titanium oxide and are obtainable by decomposing a titanium tetraalcoholate in the gas phase by reaction with steam and/or oxygen in the presence of agitated cores, and these particles are used in electrophotographic twocomponent developers.
