  Zusatzpatent zum Hauptpatent     Nr.   <B>131098.</B>    Verfahren zur Herstellung eines neuen metallhaltigen     Polyazofarbstoffes.       Es wurde gefunden,     dass    man einen neuen  metallhaltigen     Polyazofarbstoff    erhält, wenn       inan   <B>1</B>     Mol    des Farbstoffes aus 2     Kol        cliazo-          tiertem        4-Chlor-2-amino-l-phenol    und-<B>1</B>     Mol     <B>6,</B>     5'-Dioxy-2,        92'-dinal)hthylamin-7,

          V-disulfo-          säure    zunächst mit einer der Hälfte der zur  vollständigen     Metallisierung    notwendigen  Menge eines kupferabgebenden Mittels be  handelt und hierauf bis zur     Absättigung    der       metallisierbaren    Gruppen mit chromabgeben  den Mitteln weiterbehandelt.  



  Der neue Farbstoff ist ein blaugraues  Pulver, das sich in Wasser, Soda und ver  dünnter Natronlauge blau, in konzentrierter  Schwefelsäure ebenfalls blau löst. Aus neu  tralem oder     sodaalkalischem,        glaubersalz-          haltigem    Färbebad wird Baumwolle in     röt-          lichblauen    Tönen angefärbt, welche gute  Echtheitseigenschaften aufweisen.  



  <I>Beispiel:</I>  Das aus 46,<B>1</B> Teilen     5,        5'-Dioxy-2,        2-          dinaphthylamin-7,        7'-disulfosäure    und<B>28,6</B>    Teilen     diazotiertem        4-Ohlor-2---iimino-l-pheriol     erhaltene     Pressgut    wird in<B>6000</B> Teilen  heissem Wasser gelöst und unter Zusatz von  <B>,25</B> Teilen     Kupfersulfat    kristallisiert in Form  einer konzentrierten Lösung unter gutem  Rühren einige Minuten gekocht.

   Darauf gibt  man<B>30</B> Teile     Or20,9    in Form von<B>7,</B>     SO/oiger          Fluorchromlösung    zu und erhitzt<B>25-30</B>  Stunden am     RückflusskUhler.    Durch Zugabe  von Kochsalz in die noch warme Lösung  des     Farbstoffes    wird dieser     auscefällt    und  durch Filtrieren und Trocknen isoliert.



  Additional patent to main patent no. <B> 131098. </B> Process for the production of a new metal-containing polyazo dye. It has been found that a new metal-containing polyazo dye is obtained if inan <B> 1 </B> mol of the dye is composed of 2 colocated 4-chloro-2-amino-1-phenol and- <B> 1 </ B> Mol <B> 6 </B> 5'-Dioxy-2, 92'-dinal) ethylamine-7,

          V-disulfonic acid is initially treated with one half of the amount of a copper-releasing agent necessary for complete metallization and then treated further with chromium-releasing agents until the metallizable groups are saturated.



  The new dye is a blue-gray powder that dissolves blue in water, soda and dilute sodium hydroxide solution, and also blue in concentrated sulfuric acid. Cotton is dyed from neutral or soda-alkaline dye bath containing Glauber's salt in reddish blue tones, which have good fastness properties.



  <I> Example: </I> That from 46, <B> 1 </B> parts 5, 5'-dioxy-2, 2- dinaphthylamine-7, 7'-disulfonic acid and <B> 28.6 </ B> parts of diazotized 4-chloro-2-imino-1-pheriol obtained pressed material is dissolved in 6,000 parts of hot water and, with the addition of, 25 parts of copper sulfate, crystallizes in In the form of a concentrated solution, boiled for a few minutes, stirring well.

   <B> 30 </B> parts of Or20.9 are then added in the form of <B> 7 </B> SO / O fluorochromium solution and heated for <B> 25-30 </B> hours in a reflux condenser. By adding sodium chloride to the still warm solution of the dye, the dye is precipitated and isolated by filtration and drying.
