Description

Disperse Yellow 56 is a high-performance synthetic organic dye belonging to the disperse dye class, widely recognized for its bright and stable yellow hue. Its primary value lies in its excellent sublimation fastness and strong affinity for hydrophobic synthetic fibers, ensuring vibrant, durable coloration. This product is essential for manufacturers in the textile and plastics industries seeking reliable and consistent colorants for polyester, acetate, and nylon materials. CAS No. 54077-16-6 identifies this specific chemical compound.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Mass coloration of nylon and other synthetic polymers.
• Manufacturing of colored plastic masterbatches for films and molded parts.
• Production of specialty inks and toners for non-paper substrates.
• Used in the automotive industry for coloring synthetic interior textiles.
• Potential applications in research and development of new polymeric colorants.
