Abstract: Disperse dyes of the formula in which D is the radical of a diazo component, Y is a linear or branched, unsubstituted or substituted alkylene of one to four carbon atoms; R1 is hydrogen, optionally substituted linear or branched alkyl of one to four carbon atoms, optionally substituted cycloalkyl or aralkyl, phenyl, or a radical of the formula: and R2 is hydrogen or C1 to C6 alkyl which may bear chloro, bromo or cyano as a substituent; and D and the rings A and B may bear one or more further substituents other than -SO3H and -COOH; and also to their productions and their use for dyeing water-repellent fibrous materials. The dyes are eminently suitable for dyeing hydrophobic fibers, particularly polyesters, in yellow to blue-green shades of excellent fastness properties.
