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.

Abstract: Chromium complex dyes which, in the form of the free acid, have the formula ##STR1## wherein Z is hydrogen, nitro, chlorine or naphthylazo or phenylazo, wherein naphthyl or phenyl is unsubstituted or substituted by nitro, chlorine, bromine, C.sub.1-5 -alkyl or C.sub.1-5 -alkoxy, A is naphthyl or phenyl containing the oxygen atom in o-position to the azomethine and wherein naphthyl or phenyl is unsubstituted or substituted by C.sub.1-5 -alkyl, halogen or naphthylazo or phenylazo wherein naphthyl or phenyl is unsubstituted or substituted by nitro, chlorine, bromine, C.sub.1-5 -alkyl or C.sub.1-5 -alkoxy, D is sulfophenyl which is unsubstituted or substituted by nitro or chlorine, or sulfonaphthyl which is unsubstituted or substituted by nitro, and is bonded to the azo group in the ortho-position to the oxygen atom and R is chloroacetyl, bromoacetyl, .alpha.-chloroacryloyl, .alpha.-bromoacryloyl, .alpha.,.beta.-dichloropropionyl, .alpha.,.beta.
