Uses

Acid black 26 is a black agent whose coloring effect can be removed by adsorbents such as zeolites.

Preparation

5-Amino-2-(phenylamino)benzenesulfonic acid diazo, and Naphthalen-1-amine coupling, its product to diazo, and 6-Hydroxynaphthalene-2-sulfonic acid coupling.

Properties and Applications

navy blue light to dark. Blue-ray black powder. Soluble in water, in 90 ℃ water solubility of 100 g/L, slightly soluble in ethanol and acetone. The strong sulfuric acid dyes for purple, diluted to blue. The water solution is blue. Discharge sex is good. Used for wool, polyamide fiber, silk and wool blended fabric dyeing, also can be used for leather color. This product is suitable for the dye scattered hair, tops, yarn. Dye, is the best.
