  <B>Zusatzpatent</B> zum Hauptpatent Nr. 130902.    Verfahren zur Herstellung eines neuen     ehromhaltigen        Farbstoffes.       Es wurde gefunden, dass man einen neuen  chromhaltigen     Farbstoff    erhält, wenn man  auf die Chromverbindung des     Farbstoffes    aus  dianotierter     1-Amino-2-oxynaphthalin-4-sulfo-          säure    und     a-Naphthol    die Chromverbindung  des     Farbstoffes    von der Formel  
EMI0001.0009     
    einwirken lässt. Der neue Farbstoff kann  durch Eindampfen oder teilweises Eindampfen  und     Aussalzen    gewonnen werden.

   Er stellt  ein bronzierendes, dunkles Pulver dar, löst  sich in Wasser mit blauer, in 10     o/oiger     Natronlauge mit blauvioletter und in kon  zentrierter Schwefelsäure mit grünblauer  Farbe und färbt die tierische Faser in reinen,    blauen Tönen von sehr guten Echtheitseigen  schaften.  



  <I>Beispiel:</I>  10 Teile der Chromverbindung des     Azo-          farbstoffes    aus     1-Diazo-2-naphthol-4-sulfosäure     und     a-Naphthol    werden in 200 Teilen Wasser  kochend gelöst. Dann setzt man 2 Teile der  Chromverbindung des Farbstoffes der Formel  
EMI0001.0016     
    hinzu und rührt unter Kochen so lange, bis  eine einheitliche blaue Lösung entstanden ist.  Die neue Chromverbindung kann daraus zum  Beispiel durch Einengen und     Aussalzen    ab  geschieden werden.

        Die erwähnte Chromverbindung des     Tri-          phenylmethanfarbstoffeswird    dadurch erhalten,  dass man 5,15 Teile des     Natronsalzes    des       Farbstoffes    in 100 Teilen Wasser kochend  löst und mit 2,28 Teilen Chromoxyd in Form  einer     Fluorchromlösung    längere Zeit erhitzt.  Hernach wird     ausgesalzen,        abgenutscht    und  getrocknet.



  <B> Additional patent </B> to main patent no. 130902. Process for the production of a new orom-containing dye. It has been found that a new chromium-containing dye is obtained if the chromium compound of the dye of the formula is applied to the chromium compound of the dye from dianotated 1-amino-2-oxynaphthalene-4-sulfonic acid and α-naphthol
EMI0001.0009
    can act. The new dye can be obtained by evaporation or partial evaporation and salting out.

   It is a bronzing, dark powder, dissolves in water with blue, in 10% caustic soda with blue-violet and in concentrated sulfuric acid with green-blue color and colors the animal fibers in pure, blue tones with very good fastness properties.



  <I> Example: </I> 10 parts of the chromium compound of the azo dye from 1-diazo-2-naphthol-4-sulfonic acid and α-naphthol are dissolved in 200 parts of boiling water. Then 2 parts of the chromium compound of the dye of the formula are used
EMI0001.0016
    and stir while boiling until a uniform blue solution has formed. The new chromium compound can be separated therefrom, for example by concentration and salting out.

        The mentioned chromium compound of triphenylmethane dye is obtained by dissolving 5.15 parts of the sodium salt of the dye in 100 parts of boiling water and heating with 2.28 parts of chromium oxide in the form of a fluorochrome solution for a long time. Then it is salted out, suction filtered and dried.
