Black-dyeing aqueous inks comprising 20 to 95% by weight of at least one dye (A), together with 5 to 80% by weight of at least one dye chosen from the group consisting of (B) and (C), based on the total weight of the dyes (A), (B) and (C) in the ink, and 1 to 40% by weight of a water-miscible organic solvent, based on the total weight of the ink, the dye (A) containing, as the colouring part of the molecule, one or more radicals of the formula (I), (II), (III) or (IV) ##STR00001## the dye (B) containing, as the coloring part of the molecule, one or more mono- or disazo radicals containing sulfo groups or one or more radicals of the formula (V), (VI), (VII) or (VIII) ##STR00002## and the dye (C) containing, as the coloring part of the molecule, one or more mono- or disazo radicals containing sulfo groups or one or more radicals of the abovementioned formula (V), (VI), (VII) or (VIII) and one or more radicals of the abovementioned formula (I), (II), (III) or (IV), in which (G).sub.0-2 is 0 to 2 identical or different substituents from the group consisting of substituted or unsubstituted amino, hydroxyl and nitro, L is substituted or unsubstituted amino, R is halogen, C.sub.1 C.sub.4alkyl, C.sub.1 C.sub.4alkoxy, C.sub.2 C.sub.4alkanoylamino, hydroxyl, carboxyl, nitro or cyano, (V).sub.0-2 is 0 to 2 identical or different substituents from the group consisting of halogen, C.sub.1 C.sub.4alkyl, C.sub.1 C.sub.4alkoxy, .beta.-sulfatoethylsulfonyl and sulfo, (W).sub.0-1 is an N-acyl radical, if any, n is the number 0, 1, 2 or 3, m is the number 1, 2 or 3 and r and q are the number 0 or 1. The inks according to the invention are distinguished by good black shades without a change in shade in artificial light (metamerism) and an outstanding fastness to light.
