Azo dyes

Abstract

Disperse dyes of formula ##STR1## wherein D is the radical of a diazo component of formula ##STR2## Z.sub.1 is a radical of formula ##STR3## Z.sub.2 is hydrogen or a radical of formula (4), X is hydrogen, halogen, CF.sub.3, R.sub.3, OR.sub.3, NH--CO--R.sub.7, NH--CO--OR.sub.8, NH--SO.sub.2 --R.sub.7 or ##STR4## wherein R.sub.3 is C.sub.1 -C.sub.6 alkyl; R.sub.4 and R.sub.5 are each independently of the other hydrogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy-C.sub.2 -C.sub.4 alkyl; R.sub.7 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.4 alkoxy-C.sub.1 -C.sub.4 alkyl or phenyl; and R.sub.8 is C.sub.1 -C.sub.6 alkyl or C.sub.1 -C.sub.4 alkoxy-C.sub.2 -C.sub.4 alkyl; A.sub.1 is hydrogen, halogen, SO.sub.2 R.sub.3, CF.sub.3, NO.sub.2 or CN; A.sub.2 is hydrogen, halogen or CN; A.sub.3 is hydrogen or halogen, with the proviso that at least one of the substituents X, A.sub.1, A.sub.2 and A.sub.3 may not be hydrogen, and A.sub.4 is hydrogen, halogen, nitro, R.sub.3, NHCOR.sub.3 or OR.sub.3.
