  <B>Zusatzpatent</B> zum Hauptpatent Nr. 206722.    Verfahren zur Herstellung eines neuen     Farbstoffpräparates.       Es wurde gefunden, dass man ein neues,  lösliches     Farbstoffpräparat    erhält, wenn man  auf den     Azofarbstoff    aus dianotiertem     1-Amino-          2,5-dimethoxy-4-aminocarbäthoxybenzol    und  dem     Anilid    der     2,3-Oxynaphthoesäure        Ben-          zoesäure-3-sulfochlorid    in Gegenwart von       Pyridin    einwirken lässt.

   Das neue Präparat  bildet ein dunkel gefärbtes Pulver, das sich  in Wasser mit brauner Farbe löst und auf  Zusatz von Alkalien den Ausgangsfarbstoff  wieder abscheidet. Es kann zum Färben oder  Drucken von Textilien verwendet werden.  <I>Beispiel:</I>  Man verrührt 25,7 Teile des Kupplungs  produktes aus dianotiertem     1-Amino-2,5-di-          methogy-4-aminocarbäthoxy-benzol    und 2,3  Oxynaphthoesäureanilid mit 150 Teilen     Py-          ridin    bei     50-550.    Zum Gemenge lässt man  33 Teile geschmolzene     Benzoesäure-3-sulfo-          chlorid    unter     Steigenlassen    der Temperatur  zufliessen,

   und rührt noch einige Zeit bei  110-115  . Sobald eine klare, braune Lösung  entstanden und eine Probe in Wasser klar  löslich geworden ist, lässt man das Reak-         tionsgemisch    auf<B>500</B> abkühlen und destilliert  einen Teil des     Pyridins    im Vakuum ab. Den  Rückstand löst man in warmem Wasser, bin  det das     Pyridin    mit Säure, z. B. wässeriger  Salzsäure, und fällt das Kondensationsprodukt  mit     aussalzenden    Mitteln, z. B.     Natriumehlorid.  



  <B> Additional patent </B> to main patent no. 206722. Process for the production of a new dye preparation. It has been found that a new, soluble dye preparation is obtained if the azo dye made from dianotized 1-amino-2,5-dimethoxy-4-aminocarbethoxybenzene and the anilide of 2,3-oxynaphthoic acid benzoic acid-3-sulfochloride in Let the presence of pyridine act.

   The new preparation forms a dark colored powder that dissolves in water with a brown color and, when alkalis are added, redeposits the original pigment. It can be used for dyeing or printing textiles. <I> Example: </I> 25.7 parts of the coupling product of dianotized 1-amino-2,5-dimethogy-4-aminocarbethoxy-benzene and 2,3 oxynaphthoic anilide are stirred with 150 parts of pyridine at 50 -550. 33 parts of molten benzoic acid 3-sulfochloride are allowed to flow into the mixture while the temperature is increased,

   and stir for some time at 110-115. As soon as a clear, brown solution has formed and a sample has become clearly soluble in water, the reaction mixture is allowed to cool to <B> 500 </B> and some of the pyridine is distilled off in vacuo. The residue is dissolved in warm water, bind the pyridine with acid, z. B. aqueous hydrochloric acid, and the condensation product falls with salting-out agents, e.g. B. Sodium chloride.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffpräparates, dadurch gekennzeichnet, dass man auf den Azofarbstoff aus dianotier tem 1-Amino-2,5-dimethoxy-4-aminocarbäth- oxy-benzol und dem Anilid der 2,3-Oxynaph- tho-esäure Benzoesäure-3-sulfochlorid in Ge genwart von Pyridin einwirken lässt. Das neue Präparat bildet ein dunkel gefärbtes Pulver, das sich in Wasser mit brauner Farbe .löst und auf Zusatz von Alkalien den Ausgangsfarbstoff wieder abscheidet. Es kann zum Färben oder Drucken von Textilien ver wendet werden. PATENT CLAIM: Process for the production of a new dye preparation, characterized in that the azo dye from dianotier 1-amino-2,5-dimethoxy-4-aminocarbäth- oxy-benzene and the anilide of 2,3-oxynaphtho-esäure Benzoic acid-3-sulfochloride can act in the presence of pyridine. The new preparation forms a dark-colored powder that dissolves in water with a brown color and, when alkalis are added, separates the original pigment. It can be used for dyeing or printing textiles.
