ABSTRACT:
It has been found that dyestuffs of the formula ##STR1## in which p stands for an integer of from 1 to 6, and W represents, as a water-solubilizing group, the sulfo group, the sulfato group (--OSO.sub.3 H), the thiosulfato group (--S--SO.sub.3 H), the carboxyl group, the phosphato group (--OPO.sub.3 H.sub.2), the phosphonic acid group (--PO(OH).sub.2) or the phosphonic acid-semi-ester group of the formula --PO(OR)OH, wherein R represents an alkyl radical of from 1 to 5 carbon atoms, preferably the methyl or ethyl radical, are very suitable in dyeing and printing processes of synthetic polyamide fiber materials and yield brilliant and very fast dyeings and prints on these materials, especially even dyeings of textured polyamide fibers which have differences in stretching.
