  Zusatzpatent zum Hauptpatent Nr. 143027.         Verfaluen    zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man die  reduzierte Chromverbindung des Farbstoffes  aus     5-Nitro-2-diazo-l-phenol    und     2-Phenyl-          amino-5-oxy        naphthalin-7-sulfosäure        diazotiert,     mit     1,8-Dioxynaphthalin-3,6-disulfosäure    kup  pelt und mit chromabgebenden Mitteln be  handelt.  



  Der erhaltene Farbstoff stellt ein dunkles       -Pulver    dar, das sich in verdünnter Natronlauge  mit blauvioletter, in konzentrierter Schwefel  säure mit schmutzig violetter Farbe löst und  Viskose, sowie Naturseide in     rötlichgrauen     Tönen färbt.  



  <I>Beispiel:</I>  50 Teile des     Azofarbstoffes,    erhalten durch  alkalische Kupplung von 32 Teilen     2-Phenyl-          amino-5-oxynaphthalin-7-sulfosäure    mit der       Diazoverbindung    aus 15 Teilen     5-Nitro-2-          amino-l-pheiiol,    werden mit einer aus 8,7  Teilen     Cr203    enthaltenden     Chromoxydhydrat-          paste,    4 Teilen     Ätznatron,

      72 Teilen kristal-    liniertem Schwefelnatrium und 14 Teilen  Glyzerin hergestellten Chromlösung     einige     Stunden am     Rückflusskübler        zum    lochen er  hitzt. Man neutralisiert nach dem Erkalten  mit Essigsäure und filtriert. Nach dem Lösen  in Natronlauge wird in üblicher Weise     dia-          zotiert.     



  Die Suspension der     Diazoverbindurig    wird  hierauf unter Eiskühlung in eine alkalische  Lösung von 32 Teilen 1,8 -     Dioxynaphthalin-          3,6-disulfosäure    einlaufen gelassen. Nach be  endeter Kupplung wird der     Farbstoff        abfil-          triert,    hierauf in 1500 Teilen heissem Wasser  gelöst und nach Zusatz von     Chromformiat,     entsprechend 15 Teilen Chromoxyd, einige  Stunden rückfliessend gekocht. Der schwer  lösliche Farbstoff wird     abfiltriert    und ge  trocknet.



  Additional patent to main patent no. 143027. Procedure 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 diazotized from 5-nitro-2-diazo-1-phenol and 2-phenylamino-5-oxy naphthalene-7-sulfonic acid with 1 , 8-Dioxynaphthalene-3,6-disulfonic acid kup pelt and be treated with chromium donating agents.



  The dye obtained is a dark powder that dissolves in dilute sodium hydroxide solution with blue-violet, in concentrated sulfuric acid with a dirty purple color and dyes viscose and natural silk in reddish-gray tones.



  <I> Example: </I> 50 parts of the azo dye, obtained by alkaline coupling of 32 parts of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid with the diazo compound from 15 parts of 5-nitro-2- amino-1- pheiiol, are mixed with a chromium oxide hydrate paste containing 8.7 parts of Cr203, 4 parts of caustic soda,

      72 parts of crystalline sodium sulphide and 14 parts of glycerin-made chromium solution, heated for a few hours in a reflux tub to punch holes. After cooling, it is neutralized with acetic acid and filtered. After dissolving in sodium hydroxide solution, diazotization is carried out in the usual way.



  The suspension of the diazo compounds is then allowed to run into an alkaline solution of 32 parts of 1,8-dioxynaphthalene-3,6-disulfonic acid while cooling with ice. When the coupling is complete, the dye is filtered off, then dissolved in 1500 parts of hot water and, after the addition of chromium formate, corresponding to 15 parts of chromium oxide, refluxed for a few hours. The sparingly soluble dye is filtered off and dried ge.
