Abstract
Abstract Dyestuffs of the formula ##STR1## wherein R=H or optionally substituted alkyl, in particular optionally substituted C 1 -C 4 -alkyl, R 1 =H or substituent, T 1 , T 2 =H, Cl, Br, optionally substituted C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, phenyl or phenoxy, Z=optionally substituted amino group, n=0, 1 or 2, are highly suitable for dyeing and printing hydroxyl- and amido-containing materials and produce light- and wet-fast blue dyeings and prints.
