  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 182047.    Verfahren zur Herstellung eines komplex gebundenes Metall enthaltenden     Farbstoffes.       Es wurde gefunden, dass man einen komplex  gebundenes Metall enthaltenden Farbstoff her  stellen kann, wenn man 1     Mol    dianotiertes       4-Chlor-2-amirio-l-phenol,    1     Moi    dianotierte       4-Nitro-2-amino-l-phenol-6-sulfonsäure,    1     Mol          1.3-Diaminobenzol    und ein Eisen, sowie ein  Nickel abgebendes Mittel aufeinander einwir  ken lässt.  



  Der erhaltene Farbstoff stellt ein braun  schwarzes Pulver dar, das sich in Wasser  leicht mit     violettstichig    brauner Farbe löst und  vegetabilisch- sowie chromgegerbtes Leder in  echten dunkelbraunen Tönen färbt.    <I>Beispiel:</I>    10,9 Teile     1.3-Diaminobenzol    werden in  100 Teilen Wasser gelöst und mit Eis auf 0 0  gekühlt.

   Dazu gibt man die aus 12,15 Teilen       Fsrrichlorid,    7,0 Teilen Nickelsulfat     kristalli-          siert,        80        Teilen        Wasser        und        43        Teilen        80        %iger     Natronlauge erhaltene     Metallhydi-oxydsuspen-          sion        und        hierauf        weitere        13,

  3        Teile        30        %ige     Natronlauge. Zu der so erhaltenen und auf    3 0 abgekühlten     Mischung    lässt man die in  üblicher Weise hergestellte und mit Soda  neutralisierte Mischung der     Diazolösungen     aus 14,35 Teilen     4-Chlor-2-amino-l-phenol     und 23,4 Teilen     4-Nitro-2-amino-l-phenol-6-          sulfonsäure    zulaufen. Man rührt 18-20 Stun  den bei 10-18 0, nach welcher Zeit die Kupp  lung beendigt ist. Hierauf wird das Reak  tionsgemisch aufgekocht, wobei die sich bil  dende Metallverbindung des Farbstoffes völlig  in Lösung geht, und eine Stunde am Rück  fluss im Sieden gehalten.

   Der Farbstoff wird  hierauf durch Zugabe von 150 Teilen Koch  salz und 15 Teilen 30     0%iger    Salzsäure ab  geschieden, filtriert,     abgepresst    und bei mässiger  Temperatur getrocknet.



  <B> Additional patent </B> to main patent no. 182047. Process for the production of a complexed metal-containing dye. It has been found that a complex-bonded metal-containing dye can be produced by adding 1 mol of dianotated 4-chloro-2-amirio-l-phenol, 1 mol of dianotated 4-nitro-2-amino-l-phenol-6- sulfonic acid, 1 mole of 1,3-diaminobenzene and an iron, and a nickel-releasing agent can act on one another.



  The dye obtained is a brown-black powder which dissolves easily in water with a purple-tinged brown color and dyes vegetable and chrome-tanned leather in real dark brown shades. <I> Example: </I> 10.9 parts of 1,3-diaminobenzene are dissolved in 100 parts of water and cooled to 0 ° with ice.

   The metal hydroxide suspension obtained from 12.15 parts of ferric chloride, 7.0 parts of crystallized nickel sulfate, 80 parts of water and 43 parts of 80% strength sodium hydroxide solution are added, followed by a further 13,

  3 parts of 30% sodium hydroxide solution. The mixture of 14.35 parts of 4-chloro-2-amino-1-phenol and 23.4 parts of 4-nitro-2, prepared in a conventional manner and neutralized with soda, is added to the mixture thus obtained and cooled to 30 -amino-l-phenol-6-sulfonic acid run in. The mixture is stirred for 18-20 hours at 10-18 0, after which time the coupling is completed. The reaction mixture is then boiled, the metal compound of the dye which forms being completely dissolved, and the mixture is kept boiling for one hour at reflux.

   The dye is then separated out by adding 150 parts of sodium chloride and 15 parts of 30% strength hydrochloric acid, filtered, pressed off and dried at a moderate temperature.
