  Verfahren zur Darstellung von   Sulfosäuren der Gallocyaninreihe.   



   In dem Stammpatent Nr. 42399 ist angegeben, dass man zn Sulfosäuren von Farbstoffen   derGallocyaninreihe gelangen kann,   wenn man die durch Kondensation von gewöhnlichem Gallocyanin mit organischen Aminen in der Kälte bei Gegenwart von Sauerstoff und nachträgliches Erwärmen erhältlichen Kondensationsprodukte sulfiert. 



   Es wurde nun gefunden, dass man Farbstoffe, die bei derselben Klarheit erheblich grünere Nuancen liefern, erhalten kann, wenn man an Stelle der in dem Stammpatent zur 
 EMI1.1 
 Nitrosodimethylanilin und   Gallussäure)   mit organischen Aminen, die nach dem Verfahren der Anspruche 1 und 2 des Stammpatentes erhältlichen analogen Kondensationsprodukte aus   Diaethylgallocyanin (FarbstoS   aus Nitrosodiaethylanilin und Gallussäure) der   Su1fierung   unterwirft. 



   Beispiel :
50 Teile des nach dem Stammpatente Nr. 42399 erhältlichen Kondensationsproduktes ans Diaethylgallocyanin und Anilin werden in 200 Teile rauchender Schwefelsäure von 250/o Anhydridgehalt bei einer Temperatur von   10-15    eingetragen. Man erhitzt allmählich unter Rühren auf   30-400,   bis eine Probe in Soda löslich ist. Die   Roaktionsmasce   wird darauf in Wasser gegossen, ausgesalzen und in das Ammoniumsalz   übergeführt.   



   Der Farbstoff gibt im Druck sehr klare grünstichig blaue Töne, die bedeutend grüner sind als die der Produkte des Stammpatentes. 



   Selbstverständlich können auch andere   Sulfierungsmittel   zur Anwendung gelangen, wie auch an Stelle des in obigem Beispiel erwähnten Anilidoproduktes die Analogen und Homologen, wie z.   B.   das Toluido-, das Chloranilidoprodukt verwendet werden können. Die hieraus entstehenden Farbstoffe verhalten sich ähnlich wie das im Beispiel beschriebene Produkt.

  Process for the preparation of sulfonic acids of the gallocyanin series.



   The parent patent No. 42399 states that sulfonic acids from dyes of the gallocyanin series can be obtained if the condensation products obtainable by condensation of ordinary gallocyanin with organic amines in the cold in the presence of oxygen and subsequent heating are sulfated.



   It has now been found that you can obtain dyes which give significantly greener shades with the same clarity, if you instead of the in the parent patent to
 EMI1.1
 Nitrosodimethylaniline and gallic acid) with organic amines, the analogous condensation products of diaethylgallocyanine (dye from nitrosodiaethylaniline and gallic acid) obtainable by the process of claims 1 and 2 of the parent patent are subjected to the su1fierung.



   Example:
50 parts of the condensation product of diaethylgallocyanine and aniline obtainable according to the parent patent no. 42399 are introduced into 200 parts of fuming sulfuric acid with an anhydride content of 250% at a temperature of 10-15. The mixture is gradually heated to 30-400 with stirring until a sample is soluble in soda. The raw mask is then poured into water, salted out and converted into the ammonium salt.



   When printed, the dye gives very clear, greenish blue tones, which are significantly greener than those of the products in the parent patent.



   Of course, other sulfonating agents can also be used, as can the analogs and homologues, such as, for example, the anilido product mentioned in the above example. B. the toluido, the chloranilido product can be used. The resulting dyes behave similarly to the product described in the example.
