The invention relates to dye mixtures containing dyes of the general formulae I <IMAGE> and II <IMAGE> in the form of the alkali metal salts and ammonium salts, where m is the numbers 0 to 4, n is the numbers 0 to 4, p is the number 1 or 2, q is the number 1 or 2, r is the number 0 or 1, m + n is the number 2, 3 or 4, B<1> is hydrogen or chlorine, B<2> is hydrogen or chlorine, B<1> and B<2> together complete a fused benzo ring which is optionally substituted by an SO3H group, R<1> and R<2> independently of one another are hydrogen or optionally substituted lower alkyl or cyclohexyl, R<1> and R<2>, together with the nitrogen, form a saturated heterocycle and Z is a reactive radical which is customary in reactive dyes and is attached to the diazo or coupling component. The dye mixtures according to the invention are highly suitable for dyeing paper pulps.
