  • Applications

    Pigment Red 190 (CAS 6424-77-7) is a red organic pigment widely used as a colorant in coatings (including architectural and automotive finishes), printing inks (rotogravure, flexographic, and offset), and plastics (masterbatches and molded parts); it is also employed in textile pigment printing where the pigment is fixed with a binder to fabrics, enabling durable red coloration in fabric applications.
