Abstract

1485056 Water-soluble disazo dyestuffs derived from 4,4<SP>1</SP>-diamino benzene sulphanilide PRODUITS CHIMIQUES UGINE KUHLMANN 18 Dec 1974 [19 Dec 1973] 54571/74 Heading C4P Novel dyestuffs have the formula wherein A 1 and A 2 are the same or different and are the residues of coupling components containing together at least one water-solubilizing group. The coupling components may be, for example, hydroxy- and/or amino-benzene derivatives, naphthalene derivatives, acetoacetanilide derivatives or pyrazolone compounds. The dyestuffs are useful for dyeing polyamides, wool, silk and especially skins with hair or wool on them such as sheepskin.
