ABSTRACT:
Reactive dyes of the formula ##STR1## in which (R).sub.n stands for n substituents R which, independently of each other, can be C.sub.1-4 -alkyl, C.sub.1-4 -alkoxy, halogen, carboxyl, carbamoyl, N-C.sub.1-4 -alkylcarbamoyl, N,N-di-C.sub.1-4 -alkylcarbamoyl, C.sub.1-4 -alkylsulfonyl, sulfamoyl, N-C.sub.1-4 -alkylsulfamoyl or N,N-di-C.sub.1-4 -alkylsulfamoyl, n is 0 to 2, m is 1 to 2, one X is an H.sub.2 N group and the other X is a radical of the formula ##STR2## in which R.sub.1 and R.sub.2 are independently of each other hydrogen or substituted or unsubstituted C.sub.1-4 -alkyl, A is C.sub.2-4 -alkylene which can be substituted by halogen, hydroxyl, carboxyl, sulfo, phenyl, sulfophenyl or C.sub.1-4 -alkoxycarbonyl, or is cyclohexylene which can be substituted by C.sub.1-4 -alkyl, or in which the group --N(R.sub.1)--A--N(R.sub.2)-- is 1,4-piperazinediyl, and Y is a reactive radical, are suitable for dyeing and printing cellulose-containing fibre materials and produce wet- and light-fast dyeings in bright blue shades.
