Azo dyes

Disperse dyes of formula (1) wherein D is the radical of a diazo component of formula (2) or (3) Z1 is a radical of formula (4) Z2 is hydrogen or a radical of formula (4), X is hydrogen, halogen, CF3, R3, OR3, NH-CO-R7, NH-CO-OR8, NH-SO2-R7 or wherein R3 is C1-C6alkyl; R4 and R5 are each independently of the other hydrogen, C1-C4alkyl or C1-C4alkoxy-C2-C4alkyl; R7 is hydrogen, C1-C6alkyl, C1-C4alkoxy-C1-C4alkyl or phenyl; and R8 is C1-C6alkyl or C1-C4alkoxy-C2-C4alkyl; A1 is hydrogen, halogen, SO2R3, CF3, NO2 or CN; A2 is hydrogen, halogen or CN; A3 is hydrogen or halogen, with the proviso that at least one of the substituents X, A1, A2 and A3 may not be hydrogen, and A4 is hydrogen, halogen, nitro, R3, NHCOR3 or OR3.
