Abstract:
A dye mixture consisting essentially of one or more dyes of the formula (1), and one or more dyes of the formulae (2) or (3) or a mixture of formulae (2) and (3) in a mixing ratio of 70:30% by weight to 30:70% by weight: ##STR11##where:M is hydrogen or an alkali metal;D.sup.1 is a benzene or naphthalene radical;D.sup.2 is a benzene or naphthalene radical;Y is vinyl or is ethyl which is substituted in the .beta.-position by an alkali-eliminable substituent;R.sup.1 is hydrogen, alkyl of 1 to 4 carbon atoms, or alkoxy of 1 to 4 carbon atoms, when D.sup.1 is a benzene radical, or is hydrogen or sulfo, when D.sup.1 is a naphthalene radical;R.sup.2 is hydrogen, alkyl of 1 to 4 carbon atoms, or alkoxy of 1 to 4 carbon atoms, when D.sup.1 is a benzene radical, or is hydrogen or sulfo, when D.sup.1 is a naphthalene radical;R.sup.3 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxyl or sulfo, when D.sup.2 is a benzene radical, or is hydrogen or sulfo, when D.sup.2 is a naphthalene radical;R.sup.4 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, or sulfo, when D.sup.2 is a benzene radical, or is hydrogen or sulfo, when D.sup.2 is a naphthalene radical;R.sup.5 is hydrogen, chlorine, bromine or sulfo when D.sup.2 is a benzene radical, or is hydrogen or sulfo when D.sup.2 is a naphthalene radical;X.sup.1 is fluorine, bromine or chlorine;X.sup.2 is fluorine, bromine or chlorine;Z.sup.1 is a group of the general formula (4a) or (4b) ##STR12##whereR.sup.A is hydrogen or alkyl of 1 to 4 carbon atoms, which is optionally substituted with sulfo, carboxyl, methoxy, ethoxy, sulfato, phosphate, acetoxy, propionyloxy or hydroxyl,R.sup.B is hydrogen or alkyl of 1 to 4 carbon atoms, which is optionally substituted with sulfo, carboxyl, methoxy, ethoxy, sulfato, phosphate, acetoxy, propionyloxy or hydroxyl, or the group --NR.sup.A R.sup.B forms the radical of a 5- or 7-membered saturated heterocycle wherein the alkylene radical of this heterocycle is optionally additionally interrupted by 1 or 2 hetero groups,R.sup.C is hydrogen or alkyl of 1 to 4 carbon atoms, which is optionally substituted with sulfo, carboxyl, sulfato or hydroxyl, andR.sup.D is hydrogen or phenyl, which is optionally substituted by 1 or 2 substituents selected from the group consisting of alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxyl, sulfo and chlorine;Z.sup.2 has one of the meanings mentioned for Z.sup.1 ;X.sup.3 is fluorine, bromine or chlorine;Z.sup.3 has one of the meanings mentioned for Z.sup.1 ;Z.sup.0 is a group of the formula (5a), (5b), (5c) or (5d) ##STR13##whereR.sup.10 is hydrogen or chlorine;R.sup.11 is hydrogen, chlorine or fluorine;R.sup.0 is hydrogen, alkyl of 1 to 4 carbon atoms, phenyl or chlorine-, sulfo-, methyl-, ethyl-, methoxy-, ethoxy- or carboxyl-substituted phenyl;X.sup.4 has one of the meanings of X.sup.1 ;Y.sup.1 has one of the meanings of Y;B is alkylene of 2 to 6 carbon atoms, or is alkylenephenylene or phenylenealkylene each containing an alkylene of 2 to 4 carbon atoms, wherein the phenylene radicals are optionally substituted by 1 or 2 substituents selected from the group consisting of methyl, methoxy, ethyl and ethoxy, or is alkylene of 3 to 8 carbon atoms which is interrupted by 1 or 2 hetero groups;the one --SO.sub.3 M group in the sulfoaminonaphthol radicals of the formulae (1), (2), (3) is attached to the naphthalene radical in a position which is meta or para relative to the NH group;the azo group in the formula (3) is attached to the benzene nucleus in a position which is meta or para relative to the Z.sup.0 --NH-group.
