AZO DYESTUFFS

Novel azo dyes have the formula with the proviso that D-N=N- and -OH are ortho to each other. In the formula (1): D is carbocyclic or heterocyclic aryl, R is H or SO3H, R1 is H or C1-C4-alkyl, X is where Y is -NO2, -NH2 or -NH-Z, and Z is a fibre-reactive radical or a non-fibre-reactive carbonyl or...

Zusammenfassung:Novel azo dyes have the formula with the proviso that D-N=N- and -OH are ortho to each other. In the formula (1): D is carbocyclic or heterocyclic aryl, R is H or SO3H, R1 is H or C1-C4-alkyl, X is where Y is -NO2, -NH2 or -NH-Z, and Z is a fibre-reactive radical or a non-fibre-reactive carbonyl or sulphonyl radical. Suitable for preparing azo dyes (1) are novel naphtholamine derivatives of the formula where R is H or SO3H, R1 is H or C1-C4-alkyl, and X is and the compound of the formula
