  <B>Zusatzpatent</B> zum Hauptpatent Nr. 138602.    Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen     Azofarbstoff    erhält, wenn man  den     Disazofarbstoff    aus 2     Mol    dianotiertem     2-          Amino-l-phenol-4-sulfamid    und 1     Mol        5,5'-          Dioxy-    2,2'-     dinaphthylamin    -     7,

  7'-disulfosäure     zusammen mit dem     Disazofarbstoff    aus 2     Mol     dianotierter     4-Nitro-2-amino-1-phenol-6-sulfo-          säure    und 1     Mol        5,5'-Dioxy-2,2'-dinaphthyl-          amin-7,7'-disulfosäure    mit     ebromabgebenden     Mitteln behandelt.    Das neue Produkt stellt ein dunkles Pul  ver dar, löst sich in Wasser mit blauer, in  verdünnter Natronlauge und in konzentrier  ter Schwefelsäure mit rotblauer Farbe und  färbt die Faser, wie Seide,     Viscose    und Baum  wolle in blauen Tönen.

      <I>Beispiel</I>    8,4 Teile des     Disazofarbstoffes    aus 2     Mol     dianotiertem     2-Amino-l-phenol-4-sulfamid    und  1     Mol    5,5'-Dioxy-2,2'-dinaphthylamin-7,7'-di-         sulfosäure,    sowie 9,3 Teile des     Disazofarbstoffes     aus 2     Mol    dianotiertem     4-Nitro-2-amino-l-phe-          nol-6-sulfosäure    und 1     Mol        5,5'-Dioxy-2,2'-          dinaphthylamin-7,7'-disulfosäure    werden zu  sammen in 500 Teilen Wasser gelöst.

   Man  versetzt mit einer     Fluorchromlösung,    die 12  Teilen     Cr20s    entspricht, und erwärmt einige  Stunden unter Ersatz des verdampfenden  Wassers. Durch Einengen und     Aussalzen    ge  winnt man die neue Chromverbindung.



  <B> Additional patent </B> to main patent No. 138602. Process for the production of a new metal-containing dye. It has been found that a new metal-containing azo dye is obtained if the disazo dye is obtained from 2 mol of dianotated 2-amino-1-phenol-4-sulfamide and 1 mol of 5,5'-dioxy-2,2'-dinaphthylamine - 7,

  7'-disulfonic acid together with the disazo dye from 2 moles of dianotated 4-nitro-2-amino-1-phenol-6-sulfonic acid and 1 mole of 5,5'-dioxy-2,2'-dinaphthylamine-7, 7'-disulfonic acid treated with ebroma-donating agents. The new product is a dark powder that dissolves in water with blue, in dilute caustic soda and in concentrated sulfuric acid with a red-blue color and dyes the fiber, like silk, viscose and cotton, in blue tones.

      <I> Example </I> 8.4 parts of the disazo dye from 2 mol of dianotized 2-amino-1-phenol-4-sulfamide and 1 mol of 5,5'-dioxy-2,2'-dinaphthylamine-7,7 ' -Disulfonic acid, and 9.3 parts of the disazo dye from 2 moles of dianotized 4-nitro-2-amino-1-phenol-6-sulfonic acid and 1 mole of 5,5'-dioxy-2,2'-dinaphthylamine- 7,7'-disulfonic acid are dissolved together in 500 parts of water.

   A fluorochrome solution corresponding to 12 parts of Cr20s is added and the mixture is heated for a few hours, replacing the evaporating water. The new chromium compound is obtained by concentration and salting out.
