Abstract

1401750 Disazo benzanilide dyestuffs PRODUITS CHIMIQUES UGINE KUHLMANN 21 Dec 1973 [28 Dec 1972] 59360/73 Heading C4P Water-soluble benzene disazo dyestuffs have the formula in which R 1 and R 2 are the same or different and each is H or CH 3 , X is OH or NH 2 , Y is H or OH or NH 2 , and Z is H or also COOH if Y is H. They are prepared by successive coupling with the tetraazo derivative of 4,41-diaminobenzanilide, and give orange, yellow or brown hues on direct dyeing of, e.g. cotton, wool, silk, leather or paper.
