Abstract:
A dye mixture comprising one or more dyes of the formula (1) and one or more dyes of the formula (2a) or (2b) or (2a) and (2b) in a molar ratio of the dyes (1) to the dyes (2a) or (2b) or a combination of the dyes (2a) and (2b) of 70:30 to 30:70 ##STR33## where: M is hydrogen or an alkali metal; Y.sup.1 is vinyl, or is ethyl which is substituted in the .beta.-position by an alkali-eliminable substituent; D is a radical of benzene or of naphthalene; R.sup.1 is hydrogen, chlorine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, or sulfo; R.sup.2 is hydrogen, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms; R.sup.3 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or sulfo; R.sup.4 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or sulfo; R.sup.5 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or sulfo; R is amino, or alkyl of 1 to 6 carbon atoms optionally substituted; R.sup.A is amino or alkyl of 1 to 4 carbon atoms or alkyl of 1 to 4 carbon atoms which is substituted by carboxy, sulfo or a --SO.sub.2 --Y.sup.3 group, Y.sup.3 having one of the meanings of Y.sup.1 ; R.sup.B is amino or alkyl of 1 to 4 carbon atoms or alkyl of 1 to 4 carbon atoms which is substituted by carboxy, sulfo or a --SO.sub.2 --Y.sup.3 group, Y.sup.3 having one of the meanings of Y.sup.1 ; R.sup.6 is hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, hydroxy, halogen, carboxy or cyano; R.sup.7 is hydrogen, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms; m is 1, 2 or 3; Z is a fiber-reactive radical of the group of the halopyrimidines, of the dichloroquinoxalines or of the halotriazines optionally substituted by an ether or amino grouping, where the radical of the halotriazine can optionally be combined with a fiber-reactive group of the general formula --SO.sub.2 --Y, with Y having one of the meanings of Y.sup.1, which group is attached via a bridge member to an amino group attached to the triazine radical; Z.sup.o is a bivalent group of the general formula (3) ##STR34## where Hal is chlorine or fluorine, and W is phenylene, alkylene, phenylene-alkylene-phenylene, phenylene-alkenylene-phenylene or phenylene-phenylene or a group of the general formula phen-G-phen, where the phenylene groups are unsubstituted or substituted by 1 or 2 substituents selected from the group consisting of methoxy, ethoxy, methyl, ethyl, sulfo and carboxy, the alkylene groups contain 1 to 6 carbon atoms and are unsubstituted or substituted by sulfo or carboxy or interrupted by 1 or 2 hetero groups, or are unsubstituted or substituted by sulfo or carboxy and interrupted by 1 or 2 hetero groups, and the alkenylene groups are those of 2 to 4 carbon atoms, and where phen is equal to phenylene of the above definition and G is --O--, --NH--, --CO-- or --NH--CO--NH--.
