ABSTRACT:
Described are dye mixtures of dyes of the general formulae (1) and (2) ##STR1## where M is hydrogen, an alkali metal or the equivalent of an alkaline earth metal, R.sup.1, R.sup.2 and R.sup.3 are independently hydrogen or sulfo, X.sup.1 and X.sup.2, are independently chlorine, fluorine, hydroxy, alkoxy of 1 to 4 carbon atoms, optionally substituted phenyl, optionally substituted morpholino, optionally substituted pyrimidino, cyanoamino or an amino group of the formula --NR.sup.4 R.sup.5, where R.sup.4 is hydrogen, alkyl of 1 to 4 carbon atoms, unsubstituted or sulfo-substituted phenyl or unsubstituted or sulfo-substituted naphthyl, R.sup.5 is hydrogen, optionally substituted alkyl, which may be interrupted by oxy or amino, or optionally substituted phenyl or unsubstituted or sulfo-substituted naphthyl, or the group --NR.sup.4 R.sup.5 is the radical of an aliphatic heterocycle, the groups Y.sup.1 --SO.sub.2 --, Y.sup.2 --SO.sub.2 -- and Y.sup.3 --SO.sub.2 -- are each a fiber-reactive radical of the vinyl sulfone series and are attached to the benzene nucleus meta or para to the azo group.
