| abstract |
The present invention concerns orange dye mixtures of fiber-reactive azo dyes, suitable for dyeing hydroxy- and/or carboxamido-containing material such as cellulose fibers, like cotton, or wool and nylon, which comprise one or more monoazo dyestuffs corresponding to the general formula (1) and one or more monoazo dyestuffs corresponding to the formula (2) in which D1 and D2 are each, independently from one another, a radical of a benzene or naphthalene nucleus, R1, R2, R3 and R4 are each, independently from one another, hydrogen, methyl, ethyl, methoxy, ethoxy, sulfo or carboxy, M is hydrogen or an alkali metal and the group Y1-SO2- and Y2-SO2- are each fiber reactive groups of the vinylsulfone series. |
