Abstract
Substantially non-dusting, thermally stable lead chromate pigment composition consisting essentially of lead chromate pigment and at least one organic ester selected from esters of phthalic and terephthalic acids and esters of fatty acids and process of preparation by forming a mixture of lead chromate pigment and water and intimately contacting the mixture with at least one organic ester. The lead chromate pigment composition can be poured, packaged, or otherwise processed in dry form with the formation of far less dust in the work environment than is encountered using conventional lead chromate pigment and exhibits high thermal stability in plastics.
