      ZusatzPatent    zum     Hauptpatent        Nr.   <B>182047.</B>    Verfahren zur Herstellung eines komplex gebundenes       31etall    enthaltenden     Farbstoffes.       Es wurde gefunden,     dass    man einen kom  plex gebundenes Metall enthaltenden Farb  stoff herstellen kann, wenn man<B>1</B>     Mol        diazo-          tierte        4-Nitro-2-amino-l-pheijol-6-stilfoiisäure,     <B>1</B>     Mol        diazotiertes        4-Chlor-2-amii)o-l-pbenol,

       <B>1</B>     Mol        1.3-Diamiriobenzol    und ein Eisen so  wie ein Kupfer abgebendes     M,        ittel    aufein  ander einwirken     lässt.     



  Der erhaltene Farbstoff     sLellt    ein braun  schwarzes Pulver dar, das sich in Wasser  ziemlich schwer mit     gelbstichig    brauner, in  Soda leicht mit     rotstichig    dunkelbrauner Far  be löst. Es färbt     ehromgegerbtes    Leder aus  neutralem Bade in     rotstichig        clunkelbraunen     Tönen.  



  <I>Beispiel:</I>  23,4 Teile     4-1,Titro-2-awirio-l-plieiiol-6-          sulfonsäure    werden in üblicher Weise     diazo-          tiert    und mit verdünnter     Sodalösung    kongo  neutral gestellt. Diese Lösung gibt man zu  einer auf<B>50</B> abgekühlten Lösung von<B>10,9</B>  Teilen<B>1 . 3 -</B>     Diaminobenzol    in<B>100</B> Teilen    Wasser. Die Kupplung erfolgt rasch und  ist nach etwa     Istündigem    Rühren bei     5-10   <B>0</B>  beendet. Man filtriert den vollständig ausge  schiedenen Farbstoff ab     und    wäscht mit etwas  kaltem Wasser aus.

   Die     Farbstoffpaste    wird  hierauf in<B>250</B> Teilen Wasser und     13,3    Teilen       30%iger        Natronlauge        gelöst,        auf        101        abge-          kühlt    und mit der in üblicher Weise     herge#     stellten und mit Soda neutralisierten     Diazo-          lösung    aus 14,35 Teilen     4-Chlor-2-amino-l-          phenol    versetzt.

   Man rührt<B>18</B> bis 24 Stun  den bei 12 bis<B>160,</B> wonach die     Farbstoff-          bildung    beendet und die     Diazoverbindung     verschwunden ist. Nun erhitzt man zum  Kochen, versetzt mit einer Mischung,     berge-          stellt        aus        40        Volumteilen        einer        32,

  4%igen     wässerigen     Ferrichloridlösung    und 20     Volum-          teilen    einer 25     0/'oigen    wässerigen     Kupfersulfat-          lösung    und hält 1/4 Stunde im Kochen. Die  Metallverbindung des     Parbstoffes    fällt voll  ständig aus, wird     abfiltriert,    ausgewaschen  und bei mässiger Temperatur getrocknet.



      Additional patent to main patent no. <B> 182047. </B> Process for the production of a complex-bonded metal-containing dye. It has been found that a dye containing complex bonded metal can be produced if 1 mol of diazotized 4-nitro-2-amino-1-pheijol-6-stilfoiic acid is used 1 </B> mol of diazotized 4-chloro-2-amii) ol-pbenol,

       <B> 1 </B> Mol 1,3-diamiriobenzene and an iron such as a copper-releasing agent can act on one another.



  The resulting dye sLellt is a brown-black powder which is fairly difficult to dissolve in water with a yellowish brown color, and in soda easily with a reddish dark brown color. It dyes tanned leather from neutral bath in reddish dark brown tones.



  <I> Example: </I> 23.4 parts of 4-1, titro-2-awirio-1-plieiiol-6-sulfonic acid are diazotized in the usual way and made Congo neutral with dilute soda solution. This solution is added to a <B> 50 </B> solution of <B> 10.9 </B> parts <B> 1 that has been cooled to <B> 50 </B>. 3 - </B> Diaminobenzene in <B> 100 </B> parts of water. The coupling takes place quickly and is complete after about 1 hour of stirring at 5-10 <B> 0 </B>. The completely separated dye is filtered off and washed with a little cold water.

   The dye paste is then dissolved in <B> 250 </B> parts of water and 13.3 parts of 30% sodium hydroxide solution, cooled to 101 and mixed with the diazo solution of 14, neutralized with soda and prepared in the usual way. 35 parts of 4-chloro-2-amino-1-phenol are added.

   The mixture is stirred for <B> 18 </B> to 24 hours at 12 to <B> 160, </B> after which the dye formation has ended and the diazo compound has disappeared. Now it is heated to the boil, mixed with a mixture made up of 40 parts by volume of a 32,

  4% strength aqueous ferric chloride solution and 20 parts by volume of a 25% strength aqueous copper sulphate solution and keeps cooking for 1/4 hour. The metal compound of the paraffin precipitates completely, is filtered off, washed and dried at moderate temperature.
