Description

  

      Zusatzpatent    zum Hauptpatent Nr. 138602.         Verfahren    zur Herstellung eines neuen     metallhaltigen    Farbstoffes.    Es wurde gefunden, dass man einen neuen  metallhaltigen     Farbstoff    erhält, wenn man  den     Farbstoff    aus dianotierter     1-Amino-2-          oxynaphthalin-4-sulfosäure    und     ss-Naphthol     zusammen mit dem     Farbstoff    aus dianotierter       2-Amino-l-oxynaphthalin-4.        8-disulfosäure    und       ss-Naphtol    mit chromabgebenden Mitteln  behandelt.  



  Das neue Produkt stellt ein schwärzliches  Pulver dar, löst sich in Wasser mit violetter,  in verdünnter     Sodalösung    mit rotvioletter, in  konzentrierter Schwefelsäure mit blauschwar  zer Farbe und färbt Wolle und Seide in  blauen Tönen von vorzüglichen Echtheits  eigenschaften.  



  <I>Beispiel:</I>  7,88 Teile des     Azofarbstoffes    aus diano  tierter     1-Amirro-2-oxynaphtbalin-4-sulfos@ture     und     @-Naphthol    und 4,74 Teile des Farb  stoffes aus dianotierter     2-Amino-l-oxynaph-          thalin-4.8-disulfosäure    und     P-Naphthol    wer  den in 300 Teilen Wasser lochend gelöst.    Hierauf setzt man 12 Teile     Cr2Og    in Form  einer     4 /oigen        Fluorchromlösung    hinzu und  lässt das     Reaktionsgemisch    längere Zeit rück  fliessend kochen. Hernach gewinnt man den       Farbstoff    in üblicher Weise.



      Additional patent to main patent No. 138602. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and ß-naphthol together with the dye from dianotated 2-amino-1-oxynaphthalene-4. 8-disulfonic acid and ss-naphthol treated with chromium donating agents.



  The new product is a blackish powder, dissolves in water with violet, in dilute soda solution with red-violet, in concentrated sulfuric acid with blue-black color and dyes wool and silk in blue tones with excellent fastness properties.



  <I> Example: </I> 7.88 parts of the azo dye from dianotated 1-Amirro-2-oxynaphtbalin-4-sulfos @ ture and @ -naphthol and 4.74 parts of the dye from dianotated 2-Amino-1 -oxynaphthalene-4.8-disulfonic acid and P-naphthol who dissolved the punching in 300 parts of water. Then 12 parts of Cr2Og in the form of a 4% fluorochrome solution are added and the reaction mixture is allowed to reflux for a long time. The dye is then obtained in the usual way.
