Compounds of the formula <IMAGE> +TR <IMAGE> wherein each R1 is independently hydrogen, C1-4alkyl or C1-4alkyl monosubstituted by hydroxy, halo, cyano or C1-4alkoxy, each of X1 and X3 is independently halo, hydroxy, C1-4alkyl, C1-4alkoxy, phenyl, phenoxy, amino or an aliphatic, cycloaliphatic, aromatic or heterocyclic amino group, each of X2 and X4 is independently an aliphatic, cycloaliphatic, aromatic or heterocyclic amino group containing at least one protonatable nitrogen atom or quaternary ammonium group, m is 0 or 1, and each of n1 and n2 is independently 0 or 1, with the proviso that n1+n2 is 1 or 2, wherein each halo is independently fluoro, chloro or bromo, with the provisos that (1) the total number of basic and cationic groups present as X1-X4 equals or exceeds the number of sulfo groups, (2) the hydroxy or alkoxy group of each hydroxy- or alkoxy-substituted alkyl group or alkylene radical attached to a nitrogen atom is bound to a carbon atom other than the C1-atom, and (3) the hydroxy groups of each alkylene radical substituted by two hydroxy groups are attached to different carbon atoms, mixtures of such compounds and salts and mixtures with one or more copper phthalocyanine dyes containing basic and/or cationic groups, are suitable for dyeing or printing hydroxy group- or nitrogen- containing organic substrates as such or in form of solid or liquid aqueous dye preparations. They are also suitable for dyeing glass and products thereof and the preparation of inks. |
