Notes:
Many companies are facing the challenge of replacing heavy metal containing pigments in their products because of possible legal restrictions as well as toxicological and environmental considerations. Replacing one pigment in a single formulation is not generally an insurmountable problem, but replacing this pigment in hundreds or perhaps thousands of formulations might generate some anxiety. The purpose of this paper is to review some of the techniques useful for pigment selection. Colorimetric properties and physical characteristics form the basis for logical selection. Chromaticity characteristics, data on relative opacity, migration resistance, hat and light stability of more than thirty pigments will be included. Examples of the use of the techniques illustrating the replacement of chromate pigments in five colors will be presented. Comparative performance data will be included. On the basis of the information presented, limitations in making high chroma yellow will be discussed.
