    Abstract: Azo dyes of the formula [where X is oxygen or a radical of the formula NR 6 , where R 6 is hydrogen or optionally substituted C 1 -C 13 -alkyl (optionally interrupted by 1-4 ether groups and optionally substituted by hydroxy or C 1-4 -alkanoyloxy) R 1 is C 1 -C 13 -alkyl (optionally interrupted by 1-4 ether groups and optionally substituted by hydroxy or optionally halogenated C 1-4 -alkanoyloxy) or is optionally substituted phenyl, Y is hydrogen, halogen or cyano Z is nitro or additionally cyano when Y is halogen or cyano, R 2 is C 1 -C 4 -alkyl, methoxymethyl or optionally substituted phenyl, R 3 is hydrogen, C 1 -C 4 -alkoxy or C 1 -C 4 -alkyl, and R 4 and R 5 are each C 1 -C 13 -alkyl (optionally interrupted by 1-4 ether groups and optionally substituted by hydroxy, cyano or C 1-4 -alkanoyloxy) or C 2 -C 6 -alkenyl] are useful for dyeing or printing synthetic materials and are synthesizable using novel dinitroaminoaromatics (as diazo components) of formula where X, Y, Z and R 1 are as defined above. Compounds of formulae (IIa) and (IIb), which are defined in claims 11 and 12 respectively and lie within the definition of formula (II) above, are claimed per se.
