Import Direct Black 56 — Buy in Bulk from Supplier in India

Direct Black 56 is a water-soluble azo dye with C.I. No. 34170 and CAS No. 8003-57-4, supplied as a fine powder. It is designed for direct application on cellulosic fibers such as cotton, linen, and silk, and is also used in leather, paper, and wood staining.
