    摘要: 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.
