  <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-Nitro-2-amino-l-phenol,    1     Mol    dianotierte       4-Niti-o-2-amino-l-plienol-6-sulfonsäui,e,    1     Mol          1-Methyl-2.4-diaminobenzol    und ein Eisen,  sowie ein Kupfer abgebendes Mittel aufein  ander einwirken lässt.  



  Der erhaltene Farbstoff stellt ein schwarzes  Pulver dar, das sich in Wasser mit schwärz  lich brauner Farbe löst. Es färbt chromge  gerbtes Leder aus neutralem Bade in echten  dunkelbraunen Tönen.  



  <I>Beispiel:</I>  12,3 Teile     1-Methyl-2.4-diaininobenzol     werden in 100 Teilen Wasser gelöst, mit  Eis auf 3 0 abgekühlt und mit einer Metall  hydroxydsuspension aus     12,1"o    Teilen     Ferri-          chlorid,    6,25 Teilen Kupfersulfat kristallisiert,       60        Teilen        Wasser        und        43        Teilen        30        %igei,     Natronlauge, versetzt.

   Hierauf fügt man       weitere        13,3        Teile        30        %ige        Natronlauge        zu        und     die in üblicher Weise erhaltene und mit Soda  neutralisierte     Diazomischung    aus 15,4 Teilen         4-Nitro-2-amino-l-phenol    und 23,4 Teilen       4-Nitro-2-amino-l-phenol-6-sulfonsäure.    Man  kuppelt während 24 Stunden bei     10-200,     kocht hierauf auf, hält eine Stunde im Kochen  und fällt die gebildete Metallverbindung mit  100 Teilen Kochsalz und 13,

  8 Teilen     300/öiger     Salzsäure, filtriert und trocknet bei mässiger  Temperatur oder im Vakuum.



  <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 if 1 mole of dianotated 4-nitro-2-amino-1-phenol, 1 mole of dianotated 4-nitri-o-2-amino-l-plienol- 6-sulfonsäui, e, 1 mole of 1-methyl-2,4-diaminobenzene and an iron and a copper-releasing agent can act on one another.



  The dye obtained is a black powder which dissolves in water with a blackish brown color. It dyes chrome-tanned leather from neutral bath in real dark brown tones.



  <I> Example: </I> 12.3 parts of 1-methyl-2,4-diaininobenzene are dissolved in 100 parts of water, cooled to 30 with ice and treated with a metal hydroxide suspension of 12.1 parts of ferric chloride, 6 , 25 parts of copper sulfate crystallized, 60 parts of water and 43 parts of 30% strength sodium hydroxide solution were added.

   A further 13.3 parts of 30% strength sodium hydroxide solution are then added, and the diazo mixture of 15.4 parts of 4-nitro-2-amino-1-phenol and 23.4 parts of 4-nitro-2, obtained in the usual way and neutralized with soda, is added -amino-1-phenol-6-sulfonic acid. You couple for 24 hours at 10-200, then boil, keep boiling for an hour and precipitate the metal compound formed with 100 parts of table salt and 13,

  8 parts of 300 / o hydrochloric acid, filtered and dried at moderate temperature or in vacuo.
