    Abstract: Brown to violet azo dyes of the general formula where X and Y are chlorine or bromine, R1 is hydrogen, methyl, ethyl, chlorine, methoxy or ethoxy, R2 is hydrogen, chlorine, bromine, methyl, ethyl, methoxy, ethoxy, C1-4 alkanoylamino, benzoylamino or alkoxycarbonylamino, where alkoxy is of 1 to 4 carbon atoms, and the radicals R3 are identical or different, unsubstituted or substituted aliphatic, cycloaliphatic or aromatic radicals. The dyes may be used for dyeing synthetic fibers, especially polyesters, and give very fast dyeings.

    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.
