Water-Soluble Azo Dyestuffs

1,180,781. Dis- and polyazo dyes from 1,3- diamino - benzene - 4 - sulphonic acid. UGINE KUHLMANN. 31 March, 1967 [31 March, 1966], No. 14705/67. Heading C4P. The invention comprises water-soluble dis- and polyazo dyestuffs of the general formula wherein X is a coupling component residue of the benzene, heterocyclic or benzene-azobenzene series and Y is a residue of a coupling component of the benzene, naphthalene, heterocyclic or azo series. They are prepared by acylating the 1-amino group of 1,3-diamino-4- sulphonic acid, diazotizing the 3-amino group and coupling to a coupling component XH, deacylating and diazotizing the 1-amino group formed and coupling to a compound YH. The examples describe the preparation of dis- and tris-azo dyes. The dyes dye wool, silk and leather in yellow, green, red and brown shades.
