Abstract: 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.

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.
