  Zusatzpatent zum Hauptpatent     Nr.   <B>110287.</B>         Terfaln-en    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man     diazotierte        6-          Nitro-2-a.mino-l-phenol-4-karbonsä,ure    mit     3-          Aminonaplithalin-1,8-dikarbonsnure    vereinigt.  Der neue Farbstoff bildet ein braunes Pul  ver, das sieh in Wasser und in Schwefelsäure  mit     rotbrauner    Farbe löst.

   Er färbt Wolle  aus saurem Bade in     rötlichbraunen    Tönen,  welche beim     Nachehromieren    nach     gelbolive     umschlagen.  



  <I>Beispiel:</I>  <B>10,7</B> Teile     3-Aminonaplitlia.lin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von<B>10</B>  Teilen<B>30</B>     '/oiger    Natronlauge in<B>150</B> Teilen  Wasser heiss gelöst, mit<B>10</B> Teilen Soda ver  setzt, abgekühlt und mit der aus<B>9,9</B> Teilen       6-Nitro-2-amine-l-phene,1-4-karbonsä,ure    her-    gestellten     Diazoverbindung    versetzt. Nach  erfolgter Kupplung wird     der-Farbstoff        aus-          gesalzen,    filtriert und getrocknet



  Additional patent to main patent no. <B> 110287. </B> Terfaln-en for the production of a new dye. It has been found that a new dye is obtained if diazotized 6-nitro-2-a.mino-1-phenol-4-carboxylic acid is combined with 3-aminonaplithalin-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves in water and sulfuric acid with a red-brown color.

   He dyes wool from an acid bath in reddish-brown tones, which turn to yellow olive when re-homing.



  <I> Example: </I> <B> 10.7 </B> parts of 3-aminonaplitlia.lin-1,8-dicarboxylic acid anhydride are converted into <B> 10 </B> parts <B> 30 </B> '/ above sodium hydroxide solution dissolved in <B> 150 </B> parts of hot water, mixed with <B> 10 </B> parts of soda, cooled and mixed with the <B> 9.9 </ B > Parts of 6-nitro-2-amine-l-phene, 1-4-carboxylic acid, added diazo compound. After coupling has taken place, the dye is salted out, filtered and dried
