  <B>Zusatzpatent</B> zum Hauptpatent Nr. 263286.    Verfahren zur Herstellung eines sauren Farbstoffes der     Anthraebinonreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Herstellung eines neuen sauren  Farbstoffes der     Anthrachinonreihe    und ist  dadurch gekennzeichnet, dass man     1-amino-4-          brom-anthrachinon-2-sulfonsauresNatriummit          3-(4'-Chlorbenzoyl)-amino-anilin    kondensiert.  



       Irn    folgenden Beispiel bedeuten Teile  Gewichtsteile.  



       Beispiel:     20,2 Teile     1-amino-4-brom-anthrachinon-2-          sulfonsaures    Natrium,<B>18,5</B> Teile     3-(4'-Chlor-          benzoyl)-amino-anilin,    10 Teile     Natriumbikar-          bonat,    0,3 Teile Kupferpulver, 0,3 Teile     Kup-          ferchlorür,    40 Teile Äthanol und 120 Teile  Wasser werden unter Rühren während 6 Stun  den auf 70  erhitzt.  



  Die blau gewordene Kondensationsmasse  wird auf übliche Weise aufgearbeitet und lie  fert nach dem Trocknen ein blaues Farbstoff  pulver, das sich in warmem Wasser klar blau  löst. Die Farbe der Lösung in konzentrierter  Schwefelsäure ist hell blaugrün, beim Zusatz  von wenig     Paraformaldehyd    tritt ein Um  schlag nach tief grasgrün ein.  



  Der neue Farbstoff färbt Wolle, Seide  und andere tierische Fasern sowie künstliche    Fasern, wie z. B. Nylon, in schönen blauen  Tönen an. Die Färbungen sind von guter       Liehtechtheit,    sehr guter Wasch- und     Schweiss-          eehtheit    und guter     Walkechtheit.  



  <B> Additional patent </B> to main patent no. 263286. Process for the production of an acidic dye of the anthraebinone series. The present patent relates to a process for the production of a new acidic dye of the anthraquinone series and is characterized in that 1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium is condensed with 3- (4'-chlorobenzoyl) -amino-aniline.



       In the following example, parts mean parts by weight.



       Example: 20.2 parts of 1-amino-4-bromo-anthraquinone-2-sulfonic acid sodium, <B> 18.5 </B> parts of 3- (4'-chlorobenzoyl) -amino-aniline, 10 parts of sodium bicar Carbonate, 0.3 part of copper powder, 0.3 part of copper chloride, 40 parts of ethanol and 120 parts of water are heated to 70 for 6 hours while stirring.



  The condensation mass, which has turned blue, is worked up in the usual way and, after drying, delivers a blue dye powder that dissolves in warm water to give a clear blue color. The color of the solution in concentrated sulfuric acid is light blue-green; when a little paraformaldehyde is added, it changes to deep grass-green.



  The new dye dyes wool, silk and other animal fibers as well as artificial fibers such as B. Nylon, in beautiful blue tones. The dyeings are of good lightfastness, very good fastness to washing and perspiration and good fastness to flexing.
