ABSTRACT:
A dye mixture comprising one or more disazo dyes composed of 1-amino-3,6-disulfo-8-naphthol as the coupling component and of two diazo components of the aniline series containing each a fiber-reactive group of the vinylsulfone series and one or more monoazo dyes composed of a cyanoamido- or morpholino- or amino-substituted chlorotriazinylamino-sulfo-naphthol coupling component and a diazo component of the aniline series containing a fiber-reactive group of the vinylsulfone series, which dye mixtures yield on hydroxy- and/or carboxamido-containing fiber materials, such as cellulose fibers, in particular cotton, or on, for example, wool and synthetic polyamide fibers, deep black dyeings.
