Abstract: in which D is the radical of a diazo component; E is hydrogen, unsubstituted or substituted alkyl or phenyl; Z is cyano or carbamoyl; R is hydrogen or an unsubstituted or substituted aliphatic, araliphatic, cycloaliphatic or aromatic radical or two radicals R together with the nitrogen atom form a saturated heterocyclic ring; and N IS 1, 2 OR 3. The dyes are eminently suitable for dyeing natural and synthetic polyamides and give bright yellow to violet colorations having excellent fastness properties.
Azo acid dyes which contain one, two or three water-solubilizing sulfo groups and which, in the form of the free acids, correspond to the formula (I):
