ABSTRACT:
Azo dyes of the formula ##STR1## wherein D is the diazo component, the R substituents represent hydrogen or various organic radicals and X is cyano or carbamoyl. The R members are hydrogen, an alkyl or other aliphatic group as well as other selected groups including heterocyclic rings formed by R + R.sup.1 and R.sup.2 + R.sup.3 with the nitrogen atom. The dyes are eminently suitable for dyeing polyamides, cellulose esters, acrylonitrile polymers and particularly polyesters brilliant yellow to blue shades of excellent fastness properties to dry-heat pleating and setting and also to light.
