  <B>Zusatzpatent</B> zum Hauptpatent Nr. 178547.    Verfahren zur Herstellung eines     Farbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen,  direktziehenden Farbstoff der     Anthrächinon-          reihe    erhält,     wenn    man auf 1 Hol     o-Tolidin     1 Hol     1-Amino-4-bromanthrachinon-2-sulfon-          säure    und 1 Hol     Zimtsäurechlorid    einwirken  lässt.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit blauer Farbe  löst und auf Baumwolle ein reines     grün-          stichiges    Blau von vorzüglicher Lichtechtheit  erzeugt.  



  <I>Beispiel:</I>  51,3 Teile des Kondensationsproduktes aus       1-Amino-4-bi-omanthrachinon-2-sulfonsäure     und     o-Tolidin    werden in 500 Teilen Wasser  und 500 Teilen     Pyridin    gelöst. Unter gutem  Rühren tropft man 18 Teile geschmolzenes       Zimtsäurechlorid    zu und erwärmt allmählich    bis auf<B>85'.</B> Nach dem Erkalten und     Gus-          salzen    filtriert man den ausgeschiedenen Farb  stoff ab.



  <B> Additional patent </B> to main patent no. 178547. Process for the production of a dye of the anthraquinone series. It has been found that a new, substantive dye of the anthraquinone series is obtained if 1 hol of 1-amino-4-bromoanthraquinone-2-sulfonic acid and 1 hol of cinnamic acid chloride are allowed to act on 1 hol o-tolidine.



  The new dye forms a dark powder that dissolves in water with a blue color and produces a pure green-tinged blue of excellent lightfastness on cotton.



  <I> Example: </I> 51.3 parts of the condensation product of 1-amino-4-bi-omanthraquinone-2-sulfonic acid and o-tolidine are dissolved in 500 parts of water and 500 parts of pyridine. With thorough stirring, 18 parts of molten cinnamic acid chloride are added dropwise and the mixture is gradually heated to <B> 85 '. </B> After cooling and casting salts, the precipitated dye is filtered off.
