  Zusatzpatent zum Hauptpatent     Nr.    212416.    Verfahren zur Herstellung eines     Trisazofarbstoffes.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     Trisazo-          farbstoffes.    Das Verfahren ist dadurch ge  kennzeichnet,     dass    man<B>1</B>     Mol        tetrazotiertes          4,e-Diaminodiphenyl    in saurem Medium mit  <B>1</B>     Mol        1-Amino-8-oxynaphthalin-3,6-disulion-          säure    kuppelt,

   auf den gebildeten     Monoazo-          farbstoff   <B>1</B>     Mol        diazotiertes    Anilin     soda-          alkalisch    einwirken     lässt    und schliesslich mit  <B>1</B>     Mol        3-Alethylsulfamino-2'-methyl-1,1'-di-          phenylamin    kuppelt.  



  Der neue Farbstoff stellt ein dunkles Pul  ver dar, das sich in Wasser mit schwarz  violetter Farbe löst und Baumwolle in grün  schwarzen Tönen färbt.    <I>Beispiel:</I>    184 Teile     4,4'-Diaminodiphenyl    werden in  üblicher Weise     tetrazotiert    und mit 341 Tei  len     1-Amino-8-oxynaphthalin-3,6-disulfon-          säure    in mineralsaurem Medium, gekuppelt.    Dieses     Zwischenprodukt    wird     sodaalkalisch     mit einer aus<B>93</B> Teilen Anilin hergestellten       Diazobeiazollösung    vereinigt.

   Wenn keine  freie     Diazoverbindung    mehr nachzuweisen ist,  fügt man eine     natronalkalische    Lösung aus  <B>276</B> Teilen     3-Methylsulfamino-2'-metllyl-I,1'-          diphenylamin    zu. Nach kurzer Zeit ist die  Kupplung beendet. Der Farbstoff wird in der  üblichen Form abgeschieden. Er färbt Baum  wolle aus neutralem oder     sodaalkalisellem     Bad in grünschwarzen Tönen von guter Was  serechtheit. Bemerkenswert ist seine Eigen  schaft, Mischgewebe aus verschiedenen Fa  sern gleichmässig anzufärben.



  Additional patent to main patent no. 212416. Process for the production of a trisazo dye. The present patent relates to a process for the production of a trisazo dye. The process is characterized in that <B> 1 </B> mol of tetrazotized 4, e-diaminodiphenyl in an acidic medium with <B> 1 </B> mol of 1-amino-8-oxynaphthalene-3,6-disulion - acid coupling,

   lets act on the formed monoazo dye <B> 1 </B> mol of diazotized aniline in an alkaline soda and finally with <B> 1 </B> mol of 3-alethylsulfamino-2'-methyl-1,1'-di- phenylamine couples.



  The new dye is a dark powder that dissolves in water with a black-violet color and dyes cotton in green-black tones. <I> Example: </I> 184 parts of 4,4'-diaminodiphenyl are tetrazotized in the usual way and coupled with 341 parts of 1-amino-8-oxynaphthalene-3,6-disulfonic acid in a mineral acid medium. This intermediate product is combined with a soda-alkaline solution with a diazobeiazole solution made from 93 parts of aniline.

   If no more free diazo compound can be detected, an alkaline soda solution of 276 parts of 3-methylsulfamino-2'-metllyl-1,1'-diphenylamine is added. The coupling is terminated after a short time. The dye is deposited in the usual way. He dyes cotton from neutral or soda-alkaline baths in green-black tones with good waterfastness. Its ability to evenly dye mixed fabrics made from different fibers is remarkable.

PATENTANSPRUCH: Verfahren zur Herstellung eines Trisazo- farbstoffes, dadurch gekennzeichnet, dass man <B>1</B> Mol tetrazotiertes 4,4'-Diaminodiplienyl in saurem Medium mit<B>1</B> Kol 1-Amino-8-oxy- naphthalin-3,6-disulfonsäure kuppelt, PATENT CLAIM: Process for the production of a trisazo dye, characterized in that <B> 1 </B> mol of tetrazotized 4,4'-diaminodiplienyl in an acidic medium with <B> 1 </B> col 1-amino-8- oxynaphthalene-3,6-disulfonic acid couples, auf den gebildeten Monoazofarbstoff <B>1</B> Mol diazotier- tes Anilin sodaalkalisell einwirken lässt und schliesslich mit<B>1</B> Mol 3-Methylsulfamino-2'- metliyl-1,1'-diphenylamin kuppelt. Der neue Farbstoff stellt ein dunkles Pul ver dar, das sieh in Wasser mit schwarz- violetter Farbe löst und Baumwolle in grün schwarzen Tönen färbt. allows 1 mole of diazotized aniline to act on the monoazo dye formed and finally couples with 1 mole of 3-methylsulfamino-2'-methyl-1,1'-diphenylamine. The new dye is a dark powder that dissolves in water with a black-violet color and dyes cotton in green-black tones.
