    Abstract: Azo dyes of formula (I) are new. In (I), X = O or a radical NR ; R = H or 1-13C alkyl optionally with interruption by 1-4 O atoms in ether function and with or without hydroxyl or 1-4C alkanoyloxy substitution; R = 1-13C alkyl optionally with interruption by 1-4 O atoms in ether function and with or without hydroxy, 1-4C alkanoyloxy or halogen substituted-1-4C alkanoyloxy substitution, or is optionally substituted phenyl; Y = H, halogen or cyano; Z = nitro or additionally cyano when Y = halogen or cyano; R = 1-4C alkyl, methoxymethyl or optionally substituted phenyl; R = H, 1-4C alkoxy or 1-4C alkyl; and R and R = 2-13C alkyl optionally with interruption by 1-4 O atoms in ether function and with or without hydroxyl, 1-4C alkanoyloxy or cyano substitution, methyl with or without hydroxyl, 1-4C alkanoyloxy or cyano substitution, or 2-6C alkenyl. Also claimed are: (1) the use of dinitro amino aromatics of formula (II) as diazo component in the synthesis of azo dyes as above; and (2) dinitro aromatics of formula (IIa) or (IIb); In (II), X, R , Y and Z = as above. In (IIa), X and R = as above; Y = halogen or cyano; and Z = nitro or cyano. In (IIb), X = as above; and R = 3-11C alkyl optionally with interruption by 1-4 O atoms in ether function and with or without hydroxy, 1-4C alkanoyloxy or halogen substituted-1-4C alkanoyloxy substitution.

    Abstract: (a) 1,2,4-Triazolo(1,5-a)pyridine dyes (I) of formula (I) and (b) 1,2,4-triazolo(1,5-a) pyridines of formula (II) are new (where R2 = OH; SH; opt. substd. 1-20C alkyl, opt. with 1-4 ether O atoms in the chain; or an opt. substd. phenyl, 1-20C alkoxy or 1-20C alkylthio gp.; Q = -CR6=C(CR3R4R5-C(=E-R2)-; R2 = a 5-6-membered carbocyclic or heterocyclic gp., opt. benzo-annelated; R3 = H or opt. substd. 1-4C alkyl; R4 = H or opt. substd. 1-4C alkyl or 1-4C alkoxy; R5 = 1-8C alkyl, opt. with 1 or 2 ether O atoms in the chain and opt. substd. by phenyl or OH; opt. substd. phenyl or thienyl; or 1-4C alkoxy, opt. with an ether O atom in the chain; or CR3R4R5 = 3-7C cycloalkyl, 1-4C haloalkyl or opt. substd. phenyl or thienyl; R6 = CN, carbamoyl, COOH, 1-4C alkoxycarbonyl or benzothiazolyl; E = CH or N; R7 = O, C(CN)2, C(CN)COOL or C(COOL )2; L = 1-8C alkyl, opt. with 1 or 2 ether O atoms in the chain; R8 = H, CHO, NO, CN, 1-4C alkoxymethyl or CH2-NL L ; L , L = H or 1-4C alkyl, opt. with 1-4C alkylimino in the chain; or NR2L3 = a 5-6-membered satd. heterocyclic gp.; R9 = H or as R6; R10 = H, SH, halogen, -NL L or the radical of a CH-acid cpd.). Pref. cpds. are R1 in (I) = 1-13C alkyl, opt. substd. by 1-6C alkanoyloxy, 1-8C alkoxycarbonyl (opt. with 1 or 2 ether O atoms in its alkyl chain), phenyl or 1-4C alkylphenyl and opt. with 1 or 2 ether O atoms in the chain; or opt. substd. phenol; R1 in (II) 1-13C alkyl or phenyl; R2 = a gp. derived from a benzene, indole, quinoline, aminonaphthalene, pyrrole, aminothiazole, benzimidazole, benzothiazole, aminothiophene or diaminopyridine cpd.; CR3R4 = opt. substd. phenyl or thienyl; R5 = 1-5C alkyl or phenyl; R6 = CN; one of R8 and R9 = H and the other = CN, esp. R8 = H and R9 = CN.
