  Verfahren zur Herstellung eines     ehromhaltigen    Farbstoffes.    Es wurde gefunden,     dass    ein neuer,     chrom-          lialtiger    Farbstoff erhalten wird, wenn man  den     Azofarbstoff,    welcher durch     Kuppeln     der     Diazoverbindung    der     1-Amino-2-oxy-          naphtaIin-4-sulfosäure    mit     1-Oxynaphtalin-8-          sulfamid    hergestellt werden kann, mit     Al-          kalichromiten    in der Wärme behandelt.  



  Der so erhaltene chromhaltige Farbstoff  bildet ein     bronzierendes        Pulver,    das sieh in       Wasser    und in kondensierter Schwefelsäure  mit blauer Farbe löst. Er färbt Wolle aus  saurem Bade in sehr egalen blauen Tönen  von hervorragenden     Echtheitseigenschaften.       <I>Beispiel:

  </I>    47,2 Teile des Farbstoffes, erhalten durch  Kuppeln der     Diazoverbindung    der     1-Amino-          2-oxyna.pht-alin-4-sulfosäure    mit     1-Oxynaph-          talin-8-sulfami.d,    werden in ein kochendes  Gemisch aus 22,4 Teilen     Kaliumhydroxyd,     8,36 Teilen Chromoxyd. 9 Teilen     Glyzerin     und 130 Teilen Wasser eingetragen und län-         gere    Zeit am     Rückflusskühler    gekocht.

   Hier  auf wird das     Reaktionsgemisch    mit<B>300</B> Tei  len Wasser verdünnt, mit Salzsäure neutral  gestellt und die neue Chromverbindung mit       Kochsalz        ausgefällt.  



  Process for the preparation of a dye containing Ehrom. It has been found that a new, chromium-like dye is obtained when the azo dye, which can be prepared by coupling the diazo compound of 1-amino-2-oxynaphthalen-4-sulfonic acid with 1-oxynaphthalene-8-sulfamide , treated with alkali chromites in the heat.



  The chromium-containing dye obtained in this way forms a bronzing powder which dissolves in water and in condensed sulfuric acid with a blue color. It dyes wool from an acid bath in very even blue tones with excellent fastness properties. <I> example:

  </I> 47.2 parts of the dye, obtained by coupling the diazo compound of 1-amino-2-oxyna.pht-aline-4-sulfonic acid with 1-oxynaphthalen-8-sulfami.d, are added to a boiling mixture from 22.4 parts of potassium hydroxide, 8.36 parts of chromium oxide. 9 parts of glycerine and 130 parts of water entered and boiled for a long time on the reflux condenser.

   Here, the reaction mixture is diluted with <B> 300 </B> parts of water, neutralized with hydrochloric acid and the new chromium compound is precipitated with common salt.
