ABSTRACT:
Azo dyes of the formula ##STR1## wherein D is benzene, naphthalene, benzoylaminobenzene, azobenzene or stilbene, which is unsubstituted or substituted by alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, phenoxy, alkanoylamino of 1 to 6 carbon atoms, benzoylamino, amino, alkylamino of 1 to 4 carbon atoms, phenylamino, alkoxycarbonyl of 1 to 5 carbon atoms, alkylcarbonyl of 1 to 5 carbon atoms, nitro, cyano, acetyl, carbamoyl, ureido, hydroxy, carboxy, halogen or sulfo, and which contains a dihalo-s-triazinylamino or a monohalo-s-triazinylamino radical substituted by an alkyl, aryl, alkylthio, arylthio, hydroxy, alkoxy, aryloxy, -NH.sub.2, alkylamino, arylamino or heterocyclic amino group, wherein the halo-s-triazinylamino radical is bonded directly or via methylene to a ring carbon of D, and the amino group, by which the halo-s-trazinyl radical is bonded to a carbon atom in D is optionally substituted at the nitrogen atom by C.sub.1-4 -alkyl or -sulfoalkyl, R is hydrogen or alkyl of 1 to 4 carbon atoms, and R.sub.1 and R.sub.2, independently of one another, have the same meaning as those substituents referred to above of monohalo-s-triazinyl radicals in D; or a heavy metal complex thereof, are especially suitable for dyeing cotton fabric according to the exhaustion dyeing method and produce dyeings which have good fastness properties.
