  • Applications

    C.I. Acid Violet 43 is an acid dye primarily used for dyeing protein fibers such as wool and silk under acidic conditions, with compatibility to some synthetic fibers such as nylon. In practice, it is used for textile dyeing and fabric printing to achieve violet shades, and it is also used as a colorant in coatings and inks for related applications; leather finishing and dyeing processes in the leather industry may also involve it. Its use is subject to local regulations and formulation limits.
