Disperse dyes of the formula ##STR1## 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; R.sup.1 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: ##STR2## and R.sup.2 is hydrogen or C.sub.1 to C.sub.6 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 --SO.sub.3 H 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.
A compound of the formula ##STR190## in which D is thiadiazolyl substituted by methylmercapto, .beta.-cyanoethylmercapto or .beta.-C.sub.1 - to C.sub.4 -alkoxycarbonylmercapto;
