Pigment yellow 181

Pigment Yellow 181 (CAS 74441-05-7 ), also identified under C.I. 11777 and commercially available as PV Fast Yellow H 3R, is a high-performance monoazo pigment delivering a bright, reddish-yellow shade. It offers strong heat and light stability and is used across demanding colorant applications where processing conditions and end-use durability set the specification threshold for industrial use. In plastics and polymer compounding, it meets the heat resistance requirements of engineering resins and polyolefin processing, where many organic yellows fail to maintain their color integrity. Printing ink formulators select it for packaging applications requiring sharp color strength and resistance to bleed and migration into adjacent substrates during the manufacturing process. Coatings manufacturers incorporate it into industrial and decorative finishes where outdoor exposure demands sustained color integrity and resistance to environmental degradation over long periods. Textile and leather finishing operations use it in pigment printing pastes and surface coatings where fastness to washing and rubbing is a key performance criterion for the final product. The pigment is supplied as a dry powder, with press cake and dispersion forms available for wet-process applications. Standard grades are offered for plastics, coatings, and ink end uses. Particle size and surface treatment vary by application. Buyers should confirm heat resistance class and dispersibility profile against their specific processing requirements when evaluating grades.
