Abstract
Azo dyes of the formula ##STR1## where A is a radical of a diazo component, B is a radical of a coupling component and R is hydrogen, halogen, a substituted or unsubstituted hydrocarbon radical, substituted or unsubstituted alkoxy or aroxy, or substituted amino. The dyes are eminently suitable for dyeing polyester and particularly for cellulose and blends of cellulose with polyesters.
