Abstract
1403159 Naphthalene disazo benzanilide dyestuffs PRODUITS CHIMIQUES UGINE KUHLMANN 21 Dec 1973 [28 Dec 1972] 59370/73 Heading C4P Water-soluble naphthalene disazo dyestuffs have the formula in which X is OH or amino, Y is H or amino, n is 2 when X is OH or 1 or 2 when X is amino. They are prepared by coupling the tetrazo derivative of 4,41-diaminobenzanilide first with 1-amino or 1 -hydroxynaphthalene-4-sulphonic acid and then with a naphthol- or aminonaphthol-sulphonic acid, and give red to violet hues on direct dyeing of, e.g. paper, cotton, wool, silk or leather.
