Dye mixtures which contain a dye of the formula (see fig. I) together with a dye of the formula (see fig. II) in which M+ in the dyes of the formulae (1) and (2) are ammonium cations (see fig. III) which are identical to or different from one another, of an amine of the formula (see fig. IV) where R1 and R2 independently of one another are hydrogen, C1-C6alkyl or C2-C6alkyl substituted by hydroxyl or amino and, if appropriate, interrupted by an oxygen atom, and R3 is C2-C6alkyl substituted by hydroxyl or amino and, if appropriate, interrupted by an oxygen atom, afford dyeings having good fastnesses on nitrogen-containing or hydroxyl group-containing fibre materials.
