      Verfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, 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          (C113    :

   OCHS :     N112    =1: 4: 3), ein Verseif     ungs-          mittel,        Phosgen    und den     Azofarbstoff,    der er  halten werden kann durch Vereinigen der  dianotierten     2,5-Aminonaphthol-7-sulfosäure     mit     gresidin,   <B>(0113:</B>     OCHa    :     N112    =1: 4 : 3), auf  einander einwirken lässt und so zu einem Harn  stoffderivat verkettet. Der neue Farbstoff bildet  ein braunrotes Pulver; er färbt     ungebeizte     Baumwolle in sehr egalen, orangeroten 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        (0H3          OCHS        :N112    = 1:4:3), sowie 38,7 Teile des  Farbstoffes aus dianotierter     2,5-Aminonaphthol-          7-sulfosäure    und     gresidin        (CHs    :     OCHS    :     N112    =  1 :4:

   3) werden in     sodaalkalischer    Lösung bei  300 erschöpfend mit     Phosgen    behandelt und         das        erhaltene        Harnstoffderivat.        mit    3     %        iger     Natronlauge bei 900 verseift. Der neue Farb  stoff 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 dein zweiten     Azokörper     vereinigt.



      Process for the production of a new dye. It has been found that a new azo dye is obtained if the azo dye, which can be obtained by combining a dianotated derivative of 1,8 aminonaphthol-3,6-disulfonic acid with cresidine (C113:

   OCHS: N112 = 1: 4: 3), a saponifying agent, phosgene and the azo dye, which can be obtained by combining the dianotated 2,5-aminonaphthol-7-sulfonic acid with gresidin, <B> (0113: < / B> OCHa: N112 = 1: 4: 3), allowing them to act on each other and thus chaining them to a urea derivative. The new dye forms a brown-red powder; it dyes unstained cotton in very even, orange-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 (0H3 OCHS: N112 = 1: 4: 3), and 38.7 parts of the dye from dianotated 2,5-aminonaphthol- 7-sulfonic acid and gresidin (CHs: OCHS: N112 = 1: 4:

   3) are treated exhaustively with phosgene in a soda-alkaline solution at 300, and the urea derivative obtained. saponified with 3% sodium hydroxide solution at 900. The new dye is isolated in a known manner.



  The same dye is also produced when the dye is first made from the ester of 1,8-aminonaphthol-3,6-disulfonic acid; soaped and then combined with your 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 Kresi- din (0H3 : OCHS : N112 = 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 ( 0H3: OCHS: N112 = 1: 4: 3), ein Ver- seifungsmittel, Phosgen und den Azofärbstoff, der erhalten werden kann durch Vereinigen der dianotierten 2,5-Aminonaphthol-7-sulfo- säure mit Kresidin (0H3 : OCHS : N112 =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, orangeroten Tönen von sehr guter Lichtechtheit. 3), a saponifying agent, phosgene and the azo dye, which can be obtained by combining the dianotated 2,5-aminonaphthol-7-sulfonic acid with cresidine (OH3: OCHS: N112 = 1: 4: 3), interact leaves and so chained to a urea derivative. The new dye forms a brown-red powder; it dyes unstained cotton in very even, orange-red shades of very good lightfastness. UNTERANSPRüCHE 1. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass zuerst die beiden Farb stoffe durch Phosgen verkettet werden und das erhaltene Reaktionsprodukt mit einem Verseifungsmittel behandelt wird. Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass der Farbstoff aus dem Aminonaphtholsulfosäureester verseift und darauf mittelst Phosgen mit dem zweiten Farbstoff vereinigt wird. SUBClaims 1. The 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. Process according to claim, characterized in that the dye is saponified from the aminonaphtholsulfonic acid ester and then combined with the second dye by means of phosgene.
