ABSTRACT:
Compounds which in the form of the free acids have the formula I ##STR1## where K is the radical of a coupling component, n is 1, 2 or 3, R.sup.1 is hydrogen, chlorine, bromine or hydroxysulfonyl, R.sup.2 is hydrogen, chlorine, bromine, nitro, methyl or trifluoromethyl and R.sup.3 is hydrogen, alkyl of 1 to 8 carbon atoms (which may or may not be interrupted by oxygen and may be unsubstituted or substituted by hydroxyl, alkoxy of 1 to 8 carbon atoms, phenyl or phenoxy), benzyl, phenylethyl, cyclohexyl, phenyl (which may be unsubstituted or substituted by chlorine, bromine, nitro, methyl, ethyl, methoxy, ethoxy, phenoxy, dialkylamino, where alkyl is of 1 to 4 carbon atoms, or hydroxysulfonyl), naphthyl, pyridyl, thienyl or furyl. The compounds of the formula I may be used for dyeing nitrogen-containing fibers; the dyeings obtained are very fast and have brilliant hues.
