Abstract

1403969 Water-soluble disazo dyestuffs derived from 4,4<SP>1</SP>-diamino-benzanilide PRODUITS CHIMIQUES UGINE KUHLMANN 17 Jan 1974 [18 Jan 1973] 02233/74 Heading C4P Novel dyestuffs of the formula (wherein A is the residue of a coupling component of the naphthalene or pyrazole series containing at least one -SO 3 H or -CO 2 H group; R is H or alkyl; X is H, halogen, alkyl or nitro; and the -OSO 2 -C 6 H 4 -R group is in the ortho or para position with respect to the azo link) are prepared by coupling the tetrazo derivative of one mole of a coupling compound A-H in alkaline medium and then with one mole of a phenol of the formula and finally condensing the disazo compound thus obtained with one mole of an appropriate benzene sulphonyl chloride. The dyestuffs may be used for dyeing natural fibres, especially animal fibres, and also for dyeing synthetic polyamide fibres.
