Abstract
The present invention deals with metal oxide coated, flake shaped soft iron pigments. The characteristic feature is a reflector substrate, which is produced by deformation of reduced carbonyl iron powder. The pigments are colorful, display metallic luster and a high magnetic permeability. They can be oriented in the medium by means of an external magnetic field. The novel pigments find use in the decorative and/or functional field, particularly in lacquers, paints, plastics, in printing, in glass, ceramics and in cosmetics.
Claims9
Flake shaped, metal oxide coated soft iron pigments, wherein the flake shaped pigment substrates are obtained from reduced carbonyl iron powder by deformation, and the oxide coating consists of one or more transparent or selectively absorbing metal oxides.
