  Zusatzpatent zum Hauptpatent     Nr.    145448.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen       metallbaltigen    Farbstoff erhält, wenn man  den     Disazofarbstoff    der Formel:

    
EMI0001.0006     
    der durch Kuppeln von     diazotierter        Antbra-          nilsäure    in saurem Medium mit     2-Amino-5-          oxynaphthalin   <B>-7-</B>     sulfosäure    und Einwirkung  von     diazotierter        4-Ohlor-2-amino-l-phei)o1-6-          sulfosäure    auf den entstandenen     Monoazofarb-          stoff    in alkalischem Medium erhalten werden  kann, mit einem     nickel-    und einem     ehroin-          abgebenden    Mittel behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkel gefärbtes Pulver dar, das sich in  Wasser mit blauer, in konzentrierter Schwe  felsäure mit violetter Farbe löst und Viskose  in egalen grauen Tönen färbt.  



  <I>Beispiel:</I>  <B>6,7</B> Teile des     Natriumsalzes    des     Disazo-          farbstoffes    aus     diazotierter    4-Chlor-2-aniino-         1-phenol-6-stilfosätir-e    und dem Farbstoffe aus       diazotierter        Antbranilsäure    und     2-Amino-5-          oxynaphthalin.7-sulfosäure    (sauer gekuppelt)  werden in<B>500</B> Teilen Wasser gelöst und  rückfliessend mit 1,2 Teilen     Ni012    behandelt.

    Nach Zugabe von 2,2 Teilen     Cr",0,3    als     Fluor-          ehromlösung    wird weiter gekocht bis     zur     völligen     Durchmetallisierung.    Der Farbstoff  wird durch Eindampfen und Zugabe von  Kochsalz abgeschieden.



  Additional patent to main patent No. 145448. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the disazo dye of the formula:

    
EMI0001.0006
    by coupling diazotized anthanolic acid in acidic medium with 2-amino-5-oxynaphthalene <B> -7- </B> sulfonic acid and the action of diazotized 4-chloro-2-amino-l-phei) o1-6- sulfonic acid can be obtained on the resulting monoazo dye in an alkaline medium, treated with a nickel and an earring-releasing agent.



  The metal-containing dye obtained is a dark-colored powder which dissolves in water with blue, in concentrated sulfuric acid with violet color and colors viscose in level gray tones.



  <I> Example: </I> <B> 6.7 </B> parts of the sodium salt of the disazo dye from diazotized 4-chloro-2-aniino-1-phenol-6-stilfosätir-e and the dye from diazotized Antbranilic acid and 2-amino-5-oxynaphthalene.7-sulfonic acid (acid-coupled) are dissolved in 500 parts of water and treated under reflux with 1.2 parts of Ni012.

    After adding 2.2 parts of Cr ", 0.3 as a fluorine solution, the mixture is further boiled until it is completely metallized. The dye is deposited by evaporation and addition of sodium chloride.
