摘要:
In aluminum-based metal pigments produced by physical vapor deposition of a metal film and subsequent crushing of the metal film metal surfaces which are exposed after the operation of crushing the metal film and in particular fracture surfaces thereof are covered with a passivating protective layer to afford corrosion stability of those metal pigments.

摘要:
The present invention is concerned with soft-magnetic iron effect pigments with metallic luster, which are produced by grinding reductively treated carbonyl iron powder, and which are passivated either during grinding or subsequent to the grinding. The products find application in the decorative and functional fields in paint and lacquer coatings, coloring of plastics, in printing, cosmetics, and glass and ceramics.
摘要:
Luster pigments obtainable by treating titania-coated silicate-based platelets at from 400.degree. to 900.degree. C. with a gas mixture comprising a vaporized organic compound and ammonia are useful for coloring paints, inks, including printing inks, plastics, glasses, ceramic products and decorative cosmetic preparations.

Preparation of bluish luster pigments by treating titania-coated silicatic platelets with a reducing gas mixture, which comprises treating titania-coated silicatic platelets whose titania coating has a geometric layer thickness of from 10 to 60 nm at from 800.degree. to 900.degree. C. with a gas mixture comprising a vaporized organic compound and ammonia, and also bluish luster pigments based on silicatic platelets comprising a reduced titania coating with a geometric layer thickness of from 10 to 60 nm and CIELAB color coordinates -2.ltoreq.a*.ltoreq.2 and b*.ltoreq.-20 (measuring angle 20.degree., standard illuminant D65).
摘要:
Luster pigments comprising coated, plateletlike, silicatic substrates wherein the coating comprises a layer consisting essentially of carbon and aluminum oxide, chromium oxide, cerium oxide, zirconium oxide, antimony oxide or mixtures thereof, are obtainable by applying carbon-containing compounds of the metals aluminum, chromium, cerium, zirconium, antimony or mixtures thereof with or without further carbon-containing compounds of the molecular formula (CH.sub.2 O).sub.n, where n is from 1 to 6 for one monomeric unit, to the substrate particles and then thermally decomposing the carbon-containing compounds on the surface of the substrate particles under oxygen-excluding conditions.
摘要:
Mixtures useful as luster pigments for coloring paints, printing inks, plastics, decorative cosmetic preparations and ceramic products and usable in dry form in printing and coating processes consist ofA) iron oxide-coated aluminum particles andB) iron oxide-coated mica particles with or without a prior coating of a colorless, highly refractive metal oxide as essential components.

Metallically bright reflection pigments comprising a substrate of plateletlike aluminum and coatings of titanium oxides applied on top of the substrate are used for coloring paints, plastics, printing inks, ceramic articles, glasses and cosmetic products.
摘要:
Magnetic recording tape especially suitable for use as video tape and computer tape, comprising a base carrying a magnetic coating which consists essentially of a dispersion of a finely divided magnetic pigment and at least one lubricant in an organic binder. The lubricant is a compound of the formula ##STR1## IN WHICH N IS AN INTEGER OF FROM 3 TO 8 AND R.sup.1 and R.sup.2 are an alkoxy or aralkoxy radical or conjointly are an alkyldioxy radical of 3 to 18 carbon atoms. A magnetic recording tape prepared with a high proportion of such a lubricant is distinguished by high abrasion resistance coupled with a minimum transfer of material to the magnetic heads even under fluctuating climatic conditions.
