This invention relates to a black pigment, a process for making such a pigment and paints and/or plastics containing this pigment.
Heat stable black pigments which contain no carbon have generally been made from materials containing heavy metals and/or other highly toxic materials. Such materials are described, for example, in the Colour Index published in Great Britain and the brochure entitled "Classification and Chemical Descriptions of Mixed Metal Oxide Inorganic Colored Pigments" published by the Dry Color Manufacturers' Association, 1117 North 19th Street, Suite 100, Arlington, Va., 22209. These heavy metal-containing and/or highly toxic materials are, however, undesirable in many applications.
