ABSTRACT:
Described are mixtures of dyes of the general formulae (1) and (2) ##STR1## where M is hydrogen, ammonium, an alkali metal or the equivalent of an alkaline earth metal, R.sup.1 is hydrogen or sulfo, R.sup.2 is hydrogen or sulfo, X.sup.1 and X.sup.2 are each fluorine, chlorine, amino, which may be mono- or disubstituted by lower alkyl or optionally substituted aryl and one of the radicals possesses a group of the formula --SO.sup.2 --Y.sup.1 or --SO.sub.2 --Y.sup.2, where Y.sup.1 and Y.sup.2 are each vinyl or ethyl substituted in the .beta.-position by an alkali-eliminable grouping, or X.sup.1 and X.sup.2 are each optionally substituted morpholino or pyrimidino, cyanoamino, hydroxyl, lower alkoxy or optionally substituted aryloxy and where the groups --SO.sub.2 --Y.sup.1 and --SO.sub.2 --Y.sup.2 are attached to the benzene nucleus meta or para to the azo or amino group. The novel dye mixtures are used for dyeing hydroxyl- and/or carboxamido-containing material, preferably fiber material, such as cellulose fiber materials, wool and synthetic polyamide fibers.
