PCT No. PCT/DE96/00085 Sec. 371 Date Sep. 2, 1997 Sec. 102(e) Date Sep. 2, 1997 PCT Filed Jan. 16, 1996 PCT Pub. No. WO96/22336 PCT Pub. Date Jul. 25, 1996The invention concerns colored aluminum pigments comprising flake-form aluminum substrates which are coated with a metal oxide layer. The pigments are produced by a process which involves the steps of mixing a ground color pigment with a flake-form aluminum in the presence of a solvent. A metal acid ester is then added to the mixture and is then hydrolyzed to form a metal oxide layer on the aluminum substrate, followed by removal of the solvent and drying of the pigment. The pigments are useful as special-effect pigments in paints, lacquers, coatings, plastic materials, printing inks and cosmetic preparation.
