Abstract:
A dye mixture wherein the dyes consist essentially of 5 to 95% by weight of the 1:2 cobalt complex dye of the formazan compound of the formula together with at least one anthraquinone dye of the formulae (2) and (11) in whichZ is phenyl which is unsubstituted or substituted by C1-C12alkyl, C1-C4alkoxy, C2-C4alkanoylamino, hydroxyl, nitro, carboxyl, cyano, amino, halogen, benzoylaminomethyl, chloroacetylamino, chloroacetylaminomethyl, &agr;-chloroacryloylaminomethyl, acryloylaminomethyl, or by phenoxy, phenylcarbonylamino, phenylsulfonyloxy, phenylsulfonylamino, phenylsulfonylaminomethyl or N-methyl-phenylsulfonylaminomethyl, where the phenyl radicals contain no further substituents or are further substituted by C1-C12alkyl, C1-C4alkoxy, C2-C4alkanoylamino, hydroxyl, nitro, carboxyl, cyano, amino, halogen, benzoylaminomethyl, chloroacetylamino, chloroacetylaminomethyl, &agr;-chloroacryloylaminomethyl or acryloylaminomethyl, or Z is C1-C8alkyl which is unsubstituted or is substituted by phenyl, where the phenyl radical contains no further substituents or is further substituted as defined for a phenyl radical Z above, or Z is cyclohexyl which is unsubstituted or is substituted by C1-C12alkyl or phenylsulfonylamino or benzyl, where the phenyl radicals contain no further substituents or are further substituted by C1-C12alkyl, C1-C4alkoxy, C2-C4alkanoylamino or halogen, or Z is 1,2,3,4-tetrahydronaphthyl, Y is hydrogen or is as defined for Z above, and in which anthraquinone dye of the formula (2) the ring V contains no further substituents or is further substituted by one or two hydroxyl groups, and R19 and R20 are hydrogen or methyl, or together with at least one 1:2 chromium or 1:2 cobalt complex dye of two identical or different azo compounds selected from the group consisting of compounds of the formulae (3), (4), (5) and (6) in whichR3, R4, R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15 and R16 independently of one another are hydrogen, C1-C12alkyl, C1-C4alkoxy, C2-C4alkanoylamino, halogen, sulfo, hydroxyl, nitro, sulfamoyl or Nâ€”C1-C12alkylsulfamoyl, which is unsubstituted or further substituted in the alkyl moiety by hydroxyl or C1-C12alkoxy.
