Preparation

3-Amino-4-hydroxybenzenesulfonamide diazo, in alkaline conditions and 4-Hydroxy-7-(phenylamino)naphthalene-2-sulfonic acid coupling, and then into copper complex.

Properties and Applications

red light purple. Black powder. Soluble in water for purple. The strong sulfuric acid dyes for red light purple, diluted into red Violet. Dyes to join strong hydrochloric acid solution to purple; Add thick after a red light sodium hydroxide solution. Water-soluble medium, sensitive to that fights. Dyeing of copper (no change in color, meet iron ion dark colored light. Used for cotton, viscose fiber and its blended fabric and silk dyeing and printing directly, can also be used for leather and paper color.
