  Process for the preparation of a substantive o-oxyazo dye. It has been found that by coupling 1 mole of diazotized aniline and 1 mole of diazotized 2-amine-4-nitro-1-oxyberizole with 1 mole of 5-5'-dioxy-2. 2'-diiiaplitylamizi- 7 # 7'-disulfonic acid a direct target @ er <RTI

   ID = "0001.0018"> o-oxy azo dye is obtained which dyes cotton in light- and alkali-sensitive burgundy tones. By re-coppering or, even better, by dyeing in the usual way for direct dyes with the addition of copper compounds to the bath, excellent light and alkaline burgundy tones are obtained.

    <I> Example: </I> 9.3 kg of aniline and 15.4 kg of 2-amiiio-4-nitro-l-oxybenzene are diazotized and these are successively converted into a solution of 46.7 kg of 5. 5'-dioxy-2. 2'-dinapht, ylamin-7. 7 'disulfo acid and 50 kg of soda are allowed to flow in. After 12 hours, the dye is salted out, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines direkt- ziehenden o-Oxyazo,fa.rbstoffes, dadurch ge kennzeichnet, dass 9 Mol. diazotiertes Anilin und 1 Mol. diazotiertes 2-Ainino-4-nitro- 1.-oxybc,n7ol mit 1 M01. 5 # 5'-Dioxy-2 . PATENT CLAIM: Process for the production of a direct o-oxyazo, dye, characterized in that 9 mol. Of diazotized aniline and 1 mol. Of diazotized 2-ainino-4-nitro-1.-oxybc, n7ol with 1 M01. 5 # 5'-dioxy-2. 2'-di- na-plitylamin-7 # 7'-disulfosäure kombiniert werden. Der erlialtune Oxyazofarbstoff färbt direkt Baumwolle in licht- und alkaliemp- findlichen horcleaux Tönen. 2'-di-na-plitylamine-7 # 7'-disulfonic acid can be combined. The Erlialtune oxyazo dye directly dyes cotton in light- and alkali-sensitive horcleaux tones. Durch Nach kupfern oder besser durch Färben in der für direktzielienclel,7arbstoffe üblichen Weise unter Zusatz von Kupferverbindungen zum Bade werden hervorragend licht- und al- kalieclite bordeaux Töne erhalten. By re-coppering or, better, by dyeing in the manner customary for direct-target dyestuffs with the addition of copper compounds to the bath, excellent light and alkaline burgundy tones are obtained.
