3-Aminonaphthalene-1,5-disulfonic acid diazo, and 8-Aminonaphthalene-2-sulfonic acid coupling, again diazo, and 5-Aminonaphthalene-2-sulfonic acid?coupling, product to diazo, in acid conditions and 6-Amino-4-hydroxynaphthalene-2-sulfonic acid? ?coupling.

Properties and Applications

blue-ray ash. Dark grey powder. Soluble in water for blue-ray grey to black, insoluble in organic solvents. The strong sulfuric acid dyes for blu-ray grey to black solution, diluted into dark purple, have precipitation; In nitric acid solution for dark brown. The dye solution to join strong hydrochloric acid into violet, precipitation; Add thick sodium hydroxide solution with gray precipitation. Water-soluble is good, hard to sensitive. Levelness and discharge the gender is good. In dyeing copper and iron ion colored light basic unchanged. Used for cotton, viscose, silk and their blended fabric dyeing and printing, also can be used for paper and leather color. But with disperse dyestuffs with bath dyeing polyester/cotton blended high temperature fabric.
