  <B>Zusatzpatent</B> zum Hauptpatent Nr. 128006.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen  wertvollen Farbstoff erhält, wenn man den       o-Oxya.zofarbstoff,    welcher durch Vereinigen  von 2     Mol.    dianotiertem     5-Nitro-2-amino-l-          phenol    mit 1     Mol.        2,2'-Dinaphtylamin-5,5'-          dioxy-7,7'-di,suifosä.ure    entsteht, mit Chrom  abgebenden Mitteln behandelt.

   Der neue  Farbstoff stellt ein schwarzes Pulver dar,  löst sieh in Wasser und in verdünnter     Soda-          oder        Laugelösung    mit     grünlichblauer,    in  konzentrierter Schwefelsäure mit rötlich  blauer Farbe auf und färbt Baumwolle aus  neutralem     Gla.ubersalzba,de    in     grünbiauen          "l-'önen    mit guten Echtheitseigenschaften.  <I>Beispiel:</I>  31     'feile        5-Nitro-2-amino-l-phenol    wer  den dianotiert und in Gegenwart von Soda  mit 46,1. Teilen     2,2'-Dinaphtylamin-5,5'-di-          oxy-7,7'-disulfosäure    gekuppelt.

   Der     gebil-          rlete    Farbstoff wird isoliert und in 6000  Teilen Wasser gelöst. Man versetzt mit einer       Fluorchromlösung    aus 30     Teile4        Cr203    und    kocht 24 bis 36 Stunden am     Rüekflusskühler.     Durch Einengen und Salzen gewinnt man  den neuen Farbstoff.



  <B> Additional patent </B> to main patent no. 128006. Process for the production of a new azo dye. It has been found that a new valuable dye is obtained if the o-Oxya.zo dye, which is obtained by combining 2 moles of dianotated 5-nitro-2-amino-1-phenol with 1 mole of 2,2'-dinaphthylamine -5,5'-dioxy-7,7'-di, suifosä.ure arises, treated with chromium-releasing agents.

   The new dye is a black powder, dissolves in water and in dilute soda or lye solution with greenish-blue, in concentrated sulfuric acid with reddish-blue color and dyes cotton from neutral glaze over saltba, de in greenish-blue tones with good ones Fastness properties. <I> Example: </I> 31 'files 5-nitro-2-amino-1-phenol are dianotized and in the presence of soda with 46.1 parts of 2,2'-dinaphthylamine-5,5' -dioxy-7,7'-disulfonic acid coupled.

   The formed dye is isolated and dissolved in 6000 parts of water. A fluorochrome solution of 30 parts4 Cr203 is added and the mixture is boiled on a reflux condenser for 24 to 36 hours. The new dye is obtained by concentration and salting.
