  Zusatzpatent zum Hauptpatent Nr.<B>123169.</B>         Verfahren    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen       Azofarbstoff        et-hält,    wenn man den     Azofarb-          stoff,    welcher erhalten werden kann durch  Vereinigen eines dianotierten und an der       OH-Gruppe        acidylierten    Derivates der     1,8-          Aminonaphthol-3,6-disulfosäure    mit     Kresidin     (CH. i:     OCHS    :

       NH2    = 1 :4:3), ein     Verseifungs-          mittel,        Phosgen    und den     Azofarbstoff,    der  erhalten werden kann durch Vereinigen der  dianotierten     2,8-Aminonaphthol-6-sulfosäure     mit     Kresidin        (CH3.:        OCH3    :     NH2    = 1 : 4 : 3),  aufeinander einwirken lässt und so zu einem       Harnstoffderivat    verkettet.

   Der neue     Farbstoff     bildet ein braunrotes Pulver; er färbt     unge-          beizte    Baumwolle in sehr egalen, roten Tönen  von sehr guter Lichtechtheit.    <I>Beispiel:</I>    62,1 Teile des     Farbstoffes    aus' dem diano  tierten     p-Toluolsulfosäureester    der     1,8-Amino-          naphthol    - 3,6 -     disulfosäure    und     Kresidin          (CH3    :     OCH3    :     NH2    = 1 : 4 :

   3), sowie 38,7  Teile des     Farbstoffes    aus dianotierter     2,8-          Aminonaphthol    - 6 -     sulfosäure    und     Kresidin     <B>(CM</B> :     OCHS    :     NH2    = 1: 4 : 3) werden in soda-    alkalischer Lösung bei 30 o erschöpfend mit       Phosgen    behandelt und das erhaltene Harn  stoffderivat mit 3     o/oiger    Natronlauge bei 90 0  verseift. Der neue Farbstoff wird in bekannter  Weise isoliert.  



  Der gleiche Farbstoff entsteht auch, wenn  man den     Farbstoff    aus dem Ester der     1,8-          Aminonaphthol-3,6-disulfosäure    zunächst ver  seift und dann mit dem zweiten     Azokörper     vereinigt.



  Additional patent to main patent no. <B> 123169. </B> Process for the production of a new dye. It has been found that a new azo dye is retained if the azo dye, which can be obtained by combining a dianotated derivative of 1,8-aminonaphthol-3,6-disulfonic acid with cresidine, and acidylated at the OH group, is found (CH. I: OCHS:

       NH2 = 1: 4: 3), a saponifying agent, phosgene and the azo dye, which can be obtained by combining the dianotated 2,8-aminonaphthol-6-sulfonic acid with cresidine (CH3 .: OCH3: NH2 = 1: 4: 3), can act on each other and thus linked to a urea derivative.

   The new dye forms a brownish red powder; it dyes unstained cotton in very even, red shades of very good lightfastness. <I> Example: </I> 62.1 parts of the dye from the diano-tated p-toluenesulfonic acid ester of 1,8-amino naphthol - 3,6 - disulfonic acid and cresidine (CH3: OCH3: NH2 = 1: 4:

   3), and 38.7 parts of the dye from dianotized 2,8-aminonaphthol-6-sulfonic acid and cresidine (CM: OCHS: NH2 = 1: 4: 3) are added in a soda-alkaline solution 30 o treated exhaustively with phosgene and the urea derivative obtained saponified with 3 o / o sodium hydroxide solution at 90 °. The new dye is isolated in a known manner.



  The same dye is also formed when the dye from the ester of 1,8-aminonaphthol-3,6-disulfonic acid is first soaped and then combined with the second azo body.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man den Azofarbstoff, welcher erhalten werden kann durch Vereinigen eines dianotierten und an der OH-Gruppe acidylierten Derivates der 1,8-Aminonaphthol-3,6-disulfosäure mit Kresidin (CH3 : OCHS : NH2 = 1 : 4 : PATENT CLAIM: A process for the production of a new dye, characterized in that the azo dye, which can be obtained by combining a dianotated derivative of 1,8-aminonaphthol-3,6-disulfonic acid with cresidine (CH3: OCHS: NH2 = 1: 4: 3), ein Verseifungsmittel, Phosgen und den Azofarb- stoff, der erhalten werden kann durch Ver einigen der dianotierten 2,8-Aminonaphthol- 6-sulfosäure mit Kresidin (CHs : OCHS : NH2 = 1:4: 3) aufeinander einwirken lässt und so zu einem Harnstoffderivat verkettet. Der neue Farbstoff bildet ein braunrotes Pulver; er färbt ungeheizte Baumwolle in sehr egalen, roten Tönen von sehr guter Lichtechtheit. 3), a saponifying agent, phosgene and the azo dye, which can be obtained by combining some of the dianotated 2,8-aminonaphthol-6-sulfonic acid with cresidine (CHs: OCHS: NH2 = 1: 4: 3), and so chained to a urea derivative. The new dye forms a brownish red powder; it dyes unheated cotton in very even, red shades of very good lightfastness. UNTERANSPRÜCHE 1. Verfahren nach Patentanspruch, dadurch gekennzeiehnet, dass zuerst die beiden Farb stoffe durch Phosgen verkettet werden und das erhaltene Reaktionsprodukt mit einem Verseifungsmittel behandelt wird. 2. Verfahren nach Patentansprueh, dadurch gekennzeichnet, dass der Farbstoff aus dem Aminonaphtholdisulfosäureester verseift und darauf mittelst Phosgen mit dem zweiten Farbstoff vereinigt wird. SUBClaims 1. A method according to claim, characterized in that first the two dyes are linked by phosgene and the reaction product obtained is treated with a saponifying agent. 2. Process according to patent claim, characterized in that the dye is saponified from the aminonaphthol disulfonic acid ester and then combined with the second dye by means of phosgene.
