  • Applications

    Pigment Yellow 12 (CAS 6358-85-6) is a bright organic yellow pigment used primarily as a colorant in coatings and inks, including architectural paints and industrial coatings, where it provides a vivid and color-stable yellow; it is also employed in color formulations for plastics and polymers to color molded parts and extrusion compounds; in packaging and labeling inks it serves as a durable pigment for printing inks; it can be incorporated into adhesives and sealants to impart a yellow coloration; and it is used in specialty papers and decorative coatings where stable, lightfast yellow is required.
