| 摘要 |
The present invention relates to disperse dyes having the formula <IMAGE> (1) wherein X is hydrogen, halogen, C1-C8alkyl or phenyl which is unsubstituted or substituted by fluoro, chloro, bromo, methyl, methoxy or nitro; Y is cyano, C1-C4alkoxycarbonyl or nitro; Z is nitro, cyano, acetyl, benzoyl, formyl, -CH=C(CN)2, -CH=C(CN)CO2R or carbamoyl which is unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, C1-C4alkoxy-C1-C4alkyl, phenyl or (C1-C4alkyl)1-2phenyl, and R is C1-C4alkyl, or X and Z or Y and Z are each simultaneously C1-C4alkoxycarbonyl, and A, B and C are each independently of one another -NH2 or -N(R1)R2, and R1 and R2 are each independently of each other hydrogen, phenyl which is unsubstituted or substituted by hydroxy, C1-C4alkyl, halogen or C1-C4alkoxy, or is unsubstituted or C1-C4alkyl-substituted C4-C7cycloalkyl, or C1-C18alkyl which is unsubstituted or substituted by halogen, cyano, C2-C4alkanoyloxy, hydroxy, C1-C4alkoxy, phenoxy or phenyl, which phenyl or phenoxy is in turn unsubstituted or substituted by hydroxy, C1-C4alkyl, halogen or C1-C4alkoxy, and the C1-C18alkyl radical may be interrupted by oxygen atoms, or wherein R1 and R2, 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.
