  • Applications

    Disperse Black 9 is a disperse dye used to color synthetic fibers. In textile processing, it is employed for dyeing polyester and other synthetic fibers (e.g., nylon, acetate) and for printing on polyester fabrics. It is also used as a colorant in plastics and polymer formulations, including masterbatches and molded plastics, to achieve stable coloration. In coatings and inks, it serves as a dye component in formulations intended for synthetic substrates such as textiles and polymer films, including digital textile printing inks. All applications are subject to local regulations and formulation limits.
