Acid Black 2 Powder

Acid Black 2 Powder is a synthetic anionic disazo dye belonging to the acid dye class, specifically formulated for intense black coloration with excellent light and wash fastness properties. This high-purity powder (100% active) exhibits superior solubility in aqueous solutions, making it particularly suitable for dyeing protein-based fibers like wool, silk, and nylon under acidic conditions. As a chromium-complex dye, it delivers enhanced color depth and improved fastness characteristics compared to non-metalized acid dyes. The powder form ensures precise dosing, consistent batch-to-batch reproducibility, and long-term stability when stored properly. Its molecular structure features sulfonic acid groups that facilitate strong ionic bonding with amino groups in fibers, resulting in vibrant, penetration-rich coloration with minimal bleeding.
