A process for dyeing keratin-containing fibers, comprises treating said fibers with a tinctorially effective amount of a dye of the formula <IMAGE> where D is the radical of a diazo component of the formula <IMAGE> <IMAGE> <IMAGE> R1 is an unsubstituted C1-C4alkyl, or C1-C4alkyl substituted with OH, C1-C4alkoxy, halogen, CN, amino, C1-C4monoalkylamino, or di-C1-C4alkylamino, R2 and R3 are independently of each other hydrogen, an unsubstituted C1-C4alkyl, or C1-C4alkyl substituted with OH, C1-C4alkoxy, halogen, CN, amino, C1-C4monoalkylamino, or di-C1-C4alkylamino, or R3 and R2, together with the nitrogen and carbon atoms joining them together form a 5- or 6-membered ring, R5 is hydrogen, C1-C4alkoxy, halogen, C1-C4alkyl or C1-Calkylcarbonylamino, or R5 and R2, together with the nitrogen and carbon atoms joining them together form a 5- or 6-membered ring, and An theta is a colorless anion.
