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.-dibromopropionyl, 5-chloro-2,4-difluoropyrimidyl or 2-chloro- or 2-fluorotriazin-6-yl substituted in 4-position by substituted or unsubstituted amino, free or etherified hydroxy or mercapto. These dyes are obtained by chroming the corresponding o,o'-dihydrokyazo compounds and o,o'-dihydroxyazomethine compounds, the reactive radical R being introduced by acylation before or after the chroming. They are suitable for dyeing natural or synthetic polyamide material.
