Cadmium Red

An inorganic color pigment used in printing inks. Cadmium Reds range in shade from orange to maroon, and possess high lightfastness and high chemical resistance. However, if used with lead pigments, they can react with the lead, forming a blackish lead sulfide. Their toxicity precludes them from being used for foods, food packaging, toys, and many other applications. They can withstand excessively high temperatures, and their high alkali resistance makes them useful in certain applications. Cadmium pigments are rarely used any longer, having been replaced by less potentially toxic organic pigments. (See Inorganic Color Pigments.)
