ABSTRACT:
The invention relates to valuable new reactive dyestuffs of the general formula ##SPC1##
In which A stands for hydrogen, a methyl, phenyl, lower carbalkoxy, optionally substituted carboxamide or a carboxy group; B denotes a carboxy, lower carbalkoxy, optionally substituted carboxamide or nitrile group; Z means a hydroxy or amino group; R.sub.1 and R.sub.2 stand for identical or different radicals such as hydrogen or methyl; D denotes the radical of a diazo component containing a reactive group; and n means the number 0 or 1; which are suitable for the dyeing and printing of materials containing hydroxyl or amide groups and for dyeing natural or regenerated cellulose fast to washing.
