Title dyes are of formula: D-N=N-A (I) where D is the residue of a diazotisable aniline substd by in not 1 2nd order substit., or of a diazotisable amino-naphthalene, aminobiphenyl, aminoazobenzene, aminoanthraquinone, or heterocyclic amine, and A is a gp. of formula: where Z is H or a (substd). (cyclo)aliphatic, araliphatic aromatic, or heterocyclic gp; Z1 is H or a (substd). (cyclo)aliphatic, araliphatic or aromatic gp; Z2 is H or a (substd) aliphatic gp. or Z1 and Z2 form a heterocyclic gp. with the N atom; Z3 has the same meaning as Z1, Z4 has the same meaning as Z2, Z3 and Z4 may form a heterocyclic gp. with the N atom, and 1 of the gps. Z1-Z4 is not H. Suitable 2nd order substits. include NO2. CN, alkanoyl, aroyl, alkyl- or phenyl-sulphonyl, carbalkoxy (substd). carbamoyl, or sulphamoyl, or sulphonic acid ester gps. I are yellow to blue and can be used to dye polyacrylonitrile, synthetic polyamide, cellulose, ester and esp. linear polyester textiles. Fast dyeings of good colour strength are obtd.
