Complexes of the formula <IMAGE> +TR <IMAGE> and salts thereof, wherein each of X1 and X2 is independently -NR1R2, wherein R1 is hydrogen, C1-4alkyl or C2-4alkyl monosubstituted by hydroxy or C1-4-alkoxy, and R2 is hydrogen; C1-10alkyl; C2-8hydroxyalkyl; C2-8dihydroxyalkyl the hydroxy groups of which are attached to different carbon atoms; C1-6alkyl monosubstituted by halo, cyano, -OR3, (C1-4alkyl)carbonyl, (C1-4-alkoxy)carbonyl, sulfo or sulfato; phenyl; phenyl substituted by 1 or 2 substituents selected from halo, C1-4alkyl, C1-4alkoxy, acetamido and -SO2-R4; phenyl(C1-4alkyl); phenyl(C1-4alkyl) the phenyl group of which is substituted by 1 or 2 substituents selected from halo, C1-4-alkyl, C1-4alkoxy, acetamido and -SO2-R4; C5-6cycloalkyl or C5-6cycloalkyl substituted by 1 to 3 C1-4alkyl groups, wherein R3 is C1-4alkyl, C2-4-hydroxyalkyl or (C1-4-alkyl)carbonyl, and R4 is hydroxy, amino, C1-4-alkyl or phenyl, or -NR1R2 is an unsubstituted 5- or 6-membered saturated heterocyclic ring containing 1 or 2 further hetero atoms selected from nitrogen, oxygen and sulfur or a 5- or 6-membered saturated heterocyclic ring containing 1 or 2 further hetero atoms selected from nitrogen, oxygen and sulfur which is substituted by 1 to 3 C1-4alkyl groups, m is 1 or 2, and n is 0 or 1, with the proviso that m+n is 2 or 3, with the proviso that one of the asterisked bonds is in the 1-position of the naphthalene ring and the other asterisked bond is in the 2-position, and mixtures thereof are useful for dyeing or printing hydroxy group- or nitrogen-containing organic substrates. e.g., textile material consisting of or containing cellulose fibers, which may be aftertreated with a polymeric polybasic amino compound.
