Acid Blue 171 Chemical Properties,Uses,Production

Preparation

3-Amino-4-hydroxybenzenesulfonamide diazo, and N-(7-hydroxynaphthalen-1-yl)acetamide coupling, and then turn it into 1:2 cobalt complex.

Properties and Applications

dark green light blue. In aqueous solution olive gray. Suitable for wool in neutral or weak acid soluble in dyeing, good levelness, and good performance on Tippy cover, discharge the gender is poorer, mainly used to dye wool top, article nylon. Because the colour and lustre of dyeing gaudy, so is dyed dark blue dye in main body, also suitable for silk and polyamide fiber in neutral bath dyeing, the fastness and wool similar.
