Hazardous Metal-Free Color Pigments

Inorganic color pigments based on hazardous metals such as chromium, mercury, cobalt, lead, etc., account for more than 95% of the U.S. and worldwide pigments consumption. Color pigments are commonly used by numerous industries and in various consumer products. It is estimated that they are one of the largest vehicles of heavy metal-based chemicals in commerce. A technology that can provide a cost-effective, nonpolluting alternative to pigments that has a nonhazardous formulation while maintaining color performance would make a major impact in preventing pollution. This program will enable the development of such a technology.
