  Zusatzpatent zum Hauptpatent     Nr.   <B>208539-</B>    Verfahren zur Herstellung eines     Disazofarbstoffes.       Gegenstand des Hauptpatentes ist ein  -Verfahren zur Herstellung eines     Disazofarb-          Stoffes,        welühes,        dadurah    gekennzeichnet ist,

         dass        mantetrazotiertes        4.4-Diaminodiphenyl-          amin    in alkalischer Lösung mit<B>je 1</B>     Mol          1-Ät.'hyla-mino-8-oxynaphthalin-3-6--disulfon-          säure    und     3-Oxydip-lienylamin    vereinigt.  



  'Wie nun weiter gefunden wurde, erhält  man einen Farbstoff von ähnlichen     Eigen-          sohaAen,    wenn man     tetrazotiertes,        4.4'-Di-          aminodiphenylamin    in     alkaliseher    Lösung  mit<B>je 1</B>     Mol        1-Butylamino#-8-oxynaphthalin-          3-6-di,sulfo#nsä,u-re    und     Resorein    vereinigt.

  Die verwendete     1-Butyl#amiuo-8-oxynap-h-          thaäin-3-6-dis,ulfensä#u#re    wurde durch     alka-          lisehe,    Kondensation von     1-Amino,-8-oxy-          na,p'htha,lin-3-6-disulfo,nsäure    mit     n-Butyl-          chlorid    gewonnen.



  Additional patent to main patent no. <B> 208539- </B> Process for the production of a disazo dye. The subject of the main patent is a process for the production of a disazo color substance, welühes, dadurah is marked,

         that tetrazotized 4,4-diaminodiphenylamine is combined in alkaline solution with 1 mole of 1-Ät.'hyla-mino-8-oxynaphthalene-3-6-disulfonic acid and 3-oxydip-lienylamine.



  As has now been found, a dye with similar properties is obtained if tetrazotized, 4,4'-di-aminodiphenylamine is mixed in alkaline solution with 1 mole of 1-butylamino -8-oxynaphthalene- 3-6-di, sulfo # nsä, u-re and resorein combined.



  <I> Example: </I> <B> 19.9 </B> parts of 4,4'-diaminodiphenylamine are tetrazotized and <B> 37.5 </B> parts of an alkaline solution of 1-butylamino-8-oxy- na, phtha, lin-3-6-disulfo, n, acid combined. After the monoazo dye has formed, an alkaline solution of 11.0 parts of itercin is added. The finished disazo dye is obtained by salting out.

   It dyes leather in deep greenish, black tones.



  The used 1-butyl # amiuo-8-oxynap-h-thaäin-3-6-dis, ulfensä # u # re was by alkali, condensation of 1-amino, -8-oxy- na, phtha, lin-3-6-disulfonic acid obtained with n-butyl chloride.
