Abstract: Interference pigments based on multiply coated plateletlike silicatic substrates comprising A) a first layer comprising a colorless or selectively absorbing metal oxide with a high refractive index, B) a second, non-selectively absorbing, semitransparent layer consisting essentially of carbon, a metal or a metal oxide, and optionally C) a third layer comprising a colorless or selectively absorbing metal oxide in combination with scattering color pigments which are complementary in color to the reflection color of the interference pigments are useful for preparing valuable documents that are forgeryproof.

Abstract: PCT No. PCT/EP95/04576 Sec. 371 Date May 23, 1997 Sec. 102(e) Date May 23, 1997 PCT Filed Nov. 21, 1995 PCT Pub. No. WO96/02597 PCT Pub. Date Feb. 1, 1996A process for coating or printing substrates with a coating or printing composition comprises applying a polymerizable material containing liquid-crystalline, polymerizable monomers which carry at least two polymerizable groups for coating and at least one polymerizable group for printing, to the substrate, and subsequently carrying out the polymerization, where the coating composition or the printing composition comprises a1) a chiral liquid-crystalline monomer and b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), or the coating composition or the printing composition comprises a2) an achiral liquid-crystalline monomer, b) a polymeric binder and/or monomeric compounds which can be converted into the polymeric binder by polymerization, or, in the case of emulsion coatings and printing inks, a dispersion auxiliary d), and c) a non-liquid-crystalline chiral compound.

Abstract: A process is disclosed for producing pigment particles and is characterised in that: either a polymerisable mixture containing a dye or interference colouring agent is applied to a surface with recesses in the shape of the desired pigment particles, and is then polymerised, the polymerised pigment particles being afterwards removed from the recesses; or said polymerisable mixture is applied to a smooth surface in the shape of the desired pigment particles, the shape being set in the known way by a printing process, and then polymerised, the polymerised pigment particles being subsequently removed from the surface (not including the production by offset printing of pigment particles of cholesteric-liquid crystalline structure).

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.

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.
