      Zusatzpatent    zum Hauptpatent Nr. 101615.    Verfahren zur Herstellung eines     ehromhaltigen        Farbstoffes.       Es wurde gefunden, dass ein neuer     chrom-          haltiger    Farbstoff erhalten wird, wenn man  den     Azofarbstoff,    welcher durch Kuppeln  der     Diazoverbindung    aus     1-Amino-2-oxy-          naphthalin-4-sulfosäure    mit     4-Chlor-l-oxy-          naphthalin-8-sulfamid    erhalten wird, mit       Chromformiat    behandelt.

   Der neue     chromhal-          tige    Farbstoff bildet ein schwärzliches Pul  ver, löst sich in Wasser mit schwarzgrüner,  in konzentrierter Natronlauge mit violetter,  in konzentrierter Schwefelsäure mit schwärz  lichblauer Farbe und färbt Wolle aus saurem  Bade grünblau.  



  <I>Beispiel</I>  5 Teile des Farbstoffes aus     4-Chlor-l-oxy-          naphthalin-8-sulfamid    und     1-Amino-2-o.xy-          naphthalin-4-sulfosäure    werden in 100 Tei  len Wasser kochend gelöst, mit einer Chrom  formiatlösung entsprechend     2@5    Teilen     Cr20.,     versetzt und längere Zeit am     Rückfluss    ge-    kocht. Hierauf wird die gebildete Chromver  bindung durch Eindampfen und     Aussalzen     gewonnen.



      Additional patent to the main patent No. 101615. Process for the production of a dye containing Ehrom. It has been found that a new chromium-containing dye is obtained if the azo dye, which is obtained by coupling the diazo compound from 1-amino-2-oxynaphthalene-4-sulfonic acid with 4-chloro-1-oxynaphthalene-8 sulfamide is obtained, treated with chromium formate.

   The new chromium-containing dye forms a blackish powder, dissolves in water with black-green, in concentrated sodium hydroxide solution with violet, in concentrated sulfuric acid with blackish-blue color and dyes wool from acidic baths green-blue.



  <I> Example </I> 5 parts of the dye from 4-chloro-1-oxynaphthalene-8-sulfamide and 1-amino-2-o.xy-naphthalene-4-sulfonic acid are dissolved in 100 parts of boiling water , with a chromium formate solution corresponding to 2 @ 5 parts Cr20., added and refluxed for a long time. The chromium compound formed is then obtained by evaporation and salting out.
