  Zusatzpatent zum Hauptpatent     Nr.    143027.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  metallhaltigen Farbstoff erhält, wenn man  die reduzierte     Chromverbindung    des Farb  stoffes aus     5-Nitro-2-diazo-l-phenol    und     2-          Phenyl   <B>-</B>     amino   <B>- 5 -</B>     oxynaphtbalin   <B>- 7-</B>     sulfosäure          diazotiert    und mit     1-Phenyl-3-methyl-5-pyr-          azolon    kuppelt.  



  Der erhaltene Farbstoff bildet getrocknet  ein dunkles Pulver, das sich in Wasser mit  blaugrauer, in konzentrierter Schwefelsäure  mit grüngrauer Farbe löst und Viskose, sowie  chargierte Seide in grüngrauen Tönen färbt.  <I>Beispiel:</I>  <B>50</B> Teile des     Azofarbstoffes,    erhalten durch  alkalische Kupplung von<B>32</B> Teilen     2-Phenyl-          aniitio-5-oxynaplithalin-7-sLilfosäure    mit der       Diazoverbindung    aus<B>15</B> Teilen     5-Nitro-2-          amiiio-l-phenol,    werden mit einer aus<B>8,7</B>  Teilen     Cr20s    enthaltenden     Chromoxydhydrat-          paste,

      4 Teilen     Ätznatron,   <B>72</B> Teilen kristal  lisiertem Schwefelnatrium und 14 Teilen  Glyzerin hergestellten Chromlösung einige  Stunden am     Rückflusskühler    zum Kochen     er-          liitzt.    Man neutralisiert nach dem Erkalten    mit Essigsäure und filtriert.

   Nach dem Lösen  in Natronlauge wird in üblicher Weise     diazo-          tiert;    hierauf wird die Suspension der     Diazo-          verbindung    unter Eiskühlung in eine alka  lische Lösung von<B>17</B> Teilen     1-Pheiiyl-3-uie-          thyl-5-pyrazolori    fliessen     gelagsen.    Nach been  deter Kupplung wird der Farbstoff     abfiltriert     und getrocknet.



  Additional patent to main patent no. 143027. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the reduced chromium compound of the dye is obtained from 5-nitro-2-diazo-1-phenol and 2-phenyl - <B> - </B> amino <B> -5 - </B> oxynaphtbalin <B> - 7- </B> sulfonic acid diazotized and coupled with 1-phenyl-3-methyl-5-pyrazolone.



  The dye obtained forms a dark powder when dried, which dissolves in water with a blue-gray color, in concentrated sulfuric acid with a green-gray color and dyes viscose and charged silk in green-gray shades. <I> Example: </I> <B> 50 </B> parts of the azo dye, obtained by alkaline coupling of <B> 32 </B> parts of 2-phenyl-aniitio-5-oxynaplithalin-7-silfonic acid with Diazo compound from <B> 15 </B> parts of 5-nitro-2-amiiio-l-phenol are mixed with a chromium oxide hydrate paste containing <B> 8.7 </B> parts of Cr20s,

      4 parts of caustic soda, 72 parts of crystallized sodium sulphide and 14 parts of glycerine-made chromium solution are allowed to boil for a few hours on the reflux condenser. After cooling, it is neutralized with acetic acid and filtered.

   After dissolving in sodium hydroxide solution, diazotization is carried out in the usual manner; The suspension of the diazo compound is then poured into an alkaline solution of 17 parts of 1-phenyl-3-uiethyl-5-pyrazolori while cooling with ice. After coupling has been completed, the dye is filtered off and dried.
