  • Applications

    Acid green 22 (CAS 5863-51-4) is primarily used as an acid dye for protein fibers such as wool and silk, and can also dye polyamide (nylon) fibers in finishing processes. It is also used for leather coloration in processing and finishing steps. Beyond textiles, the dye serves as a colorant for paper and some water-based coatings or inks. In the plastics and polymer materials sector, acid green 22 may be used as a colourant for certain plastics and color formulations. It can also be considered for coatings and industrial inks, subject to formulation limits and local regulations.
