ABSTRACT:
The present invention relates to disperse dyes having the formula ##STR1## wherein X is hydrogen, halogen, C.sub.1 -C.sub.8 alkyl or phenyl which is unsubstituted or substituted by fluoro, chloro, bromo, methyl, methoxy or nitro; Y is cyano, C.sub.1 -C.sub.4 alkoxycarbonyl or nitro; Z is nitro, cyano, acetyl, benzoyl, formyl, --CH.dbd.C(CN).sub.2, --CH.dbd.C(CN)CO.sub.2 R or carbamoyl which is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkoxy-C.sub.1 -C.sub.4 alkyl, phenyl or (C.sub.1 -C.sub.4 alkyl).sub.1-2 phenyl, and R is C.sub.1 -C.sub.4 alkyl, or X and Z or Y and Z are each simultaneously C.sub.1 -C.sub.4 alkoxycarbonyl, and A, B and C are each independently of one another --NH.sub.2 or --N(R.sub.1)R.sub.2, and R.sub.1 and R.sub.2 are each independently of each other hydrogen, phenyl which is unsubstituted or substituted by hydroxy, C.sub.1 -C.sub.4 alkyl, halogen or C.sub.1 -C.sub.4 alkoxy, or is unsubstituted or C.sub.1 -C.sub.4 alkyl-substituted C.sub.4 -C.sub.7 cycloalkyl, or C.sub.1 -C.sub.18 alkyl which is unsubstituted or substituted by halogen, cyano, C.sub.2 -C.sub.4 alkanoyloxy, hydroxy, C.sub.1 -C.sub.4 alkoxy, phenoxy or phenyl, which phenyl or phenoxy is in turn unsubstituted or substituted by hydroxy, C.sub.1 -C.sub.4 alkyl, halogen or C.sub.1 -C.sub.4 alkoxy, and the C.sub.1 -C.sub.18 alkyl radical may be interrupted by oxygen atoms, or wherein R.sub.1 and R.sub.2, together with the linking nitrogen atom, form a piperidinyl, pyrrolidinyl or morpholinyl radical, to a process for their preparation and to the use thereof for dyeing textile materials.
