  • Applications

    C.I. Pigment Violet 3, CAS 1325-82-2, is an organic violet pigment used as a colorant in various industrial formulations. It is commonly employed in coatings and inks (including automotive finishes and paper printing inks), in polymer and plastic coloration (often formulated in masterbatches and colorant blends), and in textiles for dyeing or tinting synthetic fibers and fabrics. It is also used in decorative paints and art materials to achieve violet hues. Its application scope and formulation limits depend on local regulations and standard formulation practices.
