  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es     wurdegefunden,        dass,    man     einen    neuen       Azofarbstoff    erhält, wenn man 1     Mol        2-('3'-          [4"-Amino]        -benzoylamino-5'-amino)-benzoyl-          amino-5-@oxynaphthalin-7-sulfonsäure    mit 1       Mol        :

  diazotiertem        Anilin,        vereinigt.    Der so  erhaltene Farbstoff bildet ein rotbraunes  Pulver, das sieh .in Wasser mit     orangeroter     Farbe löst und Baumwolle in orangeroten  Tönen färbt, .die durch     Weiterdiazotieren     auf der Faser und     Entwickeln    mit     ss-Naph-          thol        intensiv    orangerot werden.  



       Beispiel:     93 Teile Anilin     werden        in    üblicher     Weise          diazotiert.    Die mit     verdünnter        Natrium-          karbonatlösung    neutralisierte     Diazolösung     wird in     eine        kalte    Lösung     aus    520 Teilen  2-(3'-     [4"-Aminol        -benzoylamino-5'-amina)-          benzoylamino-        5-.ogynaphthalin-7-sulf        onsäure,     1,

  50 Teilen     Natriumkarbonat    und 5000 Tei-         len    Wasser     eingerührt.    Nach     beendeter     Kupplung wird der Farbstoff     abfiltriert    und       getrocknet.  



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained by adding 1 mole of 2 - ('3' - [4 "-amino] -benzoylamino-5'-amino) -benzoylamino-5- @ oxynaphthalene-7-sulfonic acid 1 mole:

  diazotized aniline, combined. The dye thus obtained forms a red-brown powder which dissolves in water with an orange-red color and dyes cotton in orange-red tones, which become intensely orange-red through further diazotization on the fiber and development with s-naphthol.



       Example: 93 parts of aniline are diazotized in the usual way. The diazo solution neutralized with dilute sodium carbonate solution is poured into a cold solution of 520 parts of 2- (3'- [4 "-aminol -benzoylamino-5'-amina) -benzoylamino-5-.ogynaphthalene-7-sulfonic acid, 1,

  50 parts of sodium carbonate and 5000 parts of water are stirred in. When the coupling has ended, the dye is filtered off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man 1 Mol 2,-(3'-[4"-Amino]-benzoylamino- 5'-amino)-benzoylamino=- 5 -,oxynaphthalin-7- sulfonsäure mit 1 Mol diazotiertem Anilin vereinigt. Claim: Process for the preparation of a new azo dye, characterized in that 1 mol of 2, - (3 '- [4 "-amino] -benzoylamino-5'-amino) -benzoylamino = -5 -, oxynaphthalene-7-sulfonic acid with 1 mole of diazotized aniline combined. Der so erhaltene Farbstoff bildet ein rotbraunes Pulver, das sich in Wasser mit orangeroter Farbe löst und Baumwolle in orangeroten Tönen färbt, die durch Weiterdiazotieren auf der Faser und Ent wickeln mit ss-Naphthol intensiv orangerot werden. The dye thus obtained forms a red-brown powder which dissolves in water with an orange-red color and dyes cotton in orange-red tones, which are intensely orange-red by further diazotizing on the fiber and developing with ss-naphthol.
