The azo dyes of the formula <IMAGE> where R1 is -CN, -CON(R8)R9, -COR10, -COOR11, -SO2R12 or - CONHNHR13, R2 is hydrogen or C1-C4-alkyl, R3 is a heterocyclic radical, which may be attached via a carbonyl group, R4 is hydrogen, C1-C4-alkyl, halogen, C1-C4-alkoxy, phenoxy or -N(H)C1-C4-alkyl, R5 is hydrogen, halogen, hydroxyl, C1-C4-alkoxy, phenoxy or C1-C4-alkyl-COO-, R6 and R7 are each independently of the other hydrogen or C1-C4-alkyl, R8, R9 and R13 are each independently of the others hydrogen or substituted or unsubstituted C1-C10-alkyl, C5-C7-cycloalkyl, phenyl or naphthyl, R10, R11 and R12 are each substituted or unsubstituted C1-C10-alkyl, C5-C7-cycloalkyl, phenyl or naphthyl, X is an oxygen atom or -CHR14, R14 is hydrogen or C1-C4-alkyl, Y is a direct bond, -CH2- or -CHR5-, Z is a water-solubilising group and m is 0, 1 or 2, produce fast dyeings on nitrogen-containing or hydroxyl-containing fibre materials.
