Abstract:
Azo class reactive dyestuffs have been found which have the general formula (1) ##STR1## and in which Z.sup.1 and Z.sup.2 represent a reactive group from the pyrimidine series, X represents SR.sup.1, OR.sup.2 or NR.sup.3 R.sup.4, and the remaining substituents have the meanings given in the description, which dyestuffs are particularly suitable for dyeing hydroxyl- and amido-containing fibres, in particular cotton.
