 zirka   50 Teilen   Wasser und lässt diese Mischung unter Rühren bei 40-450 einlaufen in eine mit der nötigen Menge Soda versetzte Lösung von 34   Teilen-Naphtolnatrium. Weon   alles eingelaufen ist, erwärmt man noch zirka eine halbe Stunde auf 50-600, salzt aus,   laugt   ab, presst und trocknet. Der so erhaltene Farbstoff löst sich leicht mit blauvioletter Farbe in Wasser. 



   PATENT-ANSPRÜCHE : 
1. Verfahren zur Darstellung leicht löslicher Salze des Farbstoffes aus o-o-Tetrazo-   phenol-p-sulfosäure   und 2 Mol.   ss-Naphtol,   dadurch gekennzeichnet, dass man die Alkalisalze desselben oder die freie Farbsäure, letztere in Gegenwart von Alkalien oder Alkalisalzen mit den Oxyden, Hydroxyden oder Salzen der Metalle der Magnesiumgruppe mit Ausnahme von Beryllium behandelt.

 about 50 parts of water and let this mixture run into a solution of 34 parts of naphthol sodium to which the necessary amount of soda has been added, while stirring at 40-450. Once everything has run in, it is heated to 50-600 for about half an hour, salted out, leached, pressed and dried. The dye thus obtained dissolves easily in water with a blue-violet color.



   PATENT CLAIMS:
1. A process for the preparation of readily soluble salts of the dye from oo-tetrazo phenol-p-sulfonic acid and 2 mol. SS-naphthol, characterized in that the alkali metal salts thereof or the free dyestuff acid, the latter in the presence of alkalis or alkali metal salts with the Oxides, hydroxides or salts of the metals of the magnesium group with the exception of beryllium.
