kondensiert und das Kondensationsprodukt noch mit kupferabgebenden Mitteln behan delt. Durch Nachbehandeln des Farbstoffes mit oxydierenden Mitteln, wie Hypochlori- ten, kann die Reinheit des Farbtones noch gesteigert werden.
Beispiel: 71 Teile des Triazols, dargestellt durch Oxydation des Kupplungsproduktes aus diazotierter 4-Nitro-4'-aminostilbendisulfon- säure mit 2-Naphthylamin-5,7-disulfonsäure, zeichnet,
dass man den durch Kupplung von diazotiertem 1-Oxy-2-amino-4-chlorbenzol mit m-Anisidin erhaltenen Aminoazofarbstoff mit einem Triazol der Förmel und 25 Teile des Aminoazofarbstoffes aus 1-Oxy-2-diazo-4-chlorbenzol und m-Anisidin werden mit 650 Teilen Wasser und 150 Tei len Natronlauge 36 B6 in üblicher Weise, z. B. wie in Beispiel 1 beschrieben, konden siert und in die Kupferverbindung über geführt.
Der metallisierte Farbstoff stellt ein fast schwarzes Pulver dar; er. löst sich in Wasser mit brauner, in konzentrierter Schwefelsäure mit blauer Farbe und färbt Baumwolle in lichtechten tiefbraunen Tönen.
Additional patent to the main patent No. 225365. Process for the preparation of a direct drawing, copper-containing dye. The subject of the present additional patent is a process for the preparation of a copper-containing dye, thereby identifying

condensed and the condensation product still treated with copper releasing agents. By treating the dye with oxidizing agents such as hypochlorite, the purity of the color can be increased.
Example: 71 parts of the triazole, represented by oxidation of the coupling product of diazotized 4-nitro-4'-aminostilbenedisulfonic acid with 2-naphthylamine-5,7-disulfonic acid, shows,
that the aminoazo dye obtained by coupling diazotized 1-oxy-2-amino-4-chlorobenzene with m-anisidine with a triazole of the formula and 25 parts of the aminoazo dye from 1-oxy-2-diazo-4-chlorobenzene and m-anisidine are with 650 parts of water and 150 Tei len sodium hydroxide 36 B6 in the usual way, for. B. as described in Example 1, condensed and passed into the copper compound.
The metallized dye is an almost black powder; he. dissolves in water with brown, in concentrated sulfuric acid with blue color and dyes cotton in lightfast deep brown tones.
