ABSTRACT:
There are described novel yellow to red azo compounds of the formula I ##STR1## wherein each D independently of the other is the radical of an aromatic or heterocyclic diazo component, each Z independently of the other is hydrogen or a C.sub.1 -C.sub.4 -alkyl group or an acylamino group, Y is hydrogen or an unsubstituted or substituted C.sub.1 -C.sub.6 -alkyl group, X is either the direct bond or C.sub.1 -C.sub.6 -alkylene, ##STR2## and n is a number from 2 to 6, preferably 2; and the substituent Y, in the case of an unsubstituted or substituted C.sub.1 -C.sub.6 -alkyl group, can also be bonded to the o-position relative to the N atom of the phenylene group to form a six-membered ring, or both Y substituents can be linked together to form a C.sub.1 -C.sub.6 -alkylene bridge; described also are processes for producing the novel compounds, and their use as dyes for dyeing and printing natural and synthetic textile materials, particularly polyamide and wool materials, and also cotton, whereby there are obtained dyeings which are distinguished by good general fastness properties, especially by a good dye build-up, very good fastness to wet processing, good fastness to light, and good resistance to formaldehyde and good stability to hydrolysis.
