Abstract

1527878 Water-soluble disazo dyestuffs HOECHST AG 19 Dec 1975 [20 Dec 1974] 52076/75 Heading C4P Novel dyestuffs of the formula (wherein R 1 and R 2 are each H, CH 3 , C 2 H 5 or OCH 3 and R 3 is H,À Cl or C 1-4 alkyl) are prepared by coupling the diazo compound of 4-aminoazobenzene-3,4'-disulphonic acid with a compound of one of the formulae (wherein T is H, SO 3 H or CH 2 SO 3 H), when necessary hydrolysing to remove T, and acylating with benzoyl chloride or a halo- or alkyl-benzoyl chloride. They are used for dyeing or printing synthetic polyamide fibres.
