ABSTRACT:
Novel reactive dyes of the formula ##STR1## in which (R).sub.0-3 is 0-3 substituents R, independent of one another, from the group comprising halogen, nitro, cyano, trifluoromethyl, sulfamoyl, carbamoyl, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, amino, acetylamino, ureido, hydroxyl, carboxyl, sulfomethyl and sulfo, R.sub.1 is hydrogen, C.sub.1-8 alky or C.sub.5-7 cycloalkyl and R.sub.2 is C.sub.1-8 alkyl or C.sub.5-7 cycloalkyl, it being possible for the alkyl and cycloalkyl radicals R.sub.1 and R.sub.2 to be substituted independently of one another by hydroxyl, C.sub.1-4 alkoxy, hydroxy-C.sub.1-4 alkoxy, HO--(CH.sub.2 CH.sub.2 --O).sub.2-4 --, sulfato-C.sub.1-4 alkoxy, C.sub.2-4 alkanoyl, C.sub.1-4 alkoxy-carbonyl, C.sub.2-4 alkanoyloxy, carboxyl, cyano, halogen, C.sub.1-4 alkylamino, or N,N-Di-C.sub.1-4 alkylamino, or sulfato, or in which R.sub.1 is C.sub.1-8 alkyl or C.sub.5-7 cycloalkyl, and the alkyl or cycloalkyl radical can be substituted as defined, and R.sub.2 is a C.sub.1-8 alkyl or C.sub.5-7 cycloalkyl radical which is substituted by sulfo, give deep yellow to orange dyeings and prints with good fastness properties on cellulose fibres.
