  Zusatzpatent zum Hauptpatent     Nr.   <B>99522.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden',     dass    man einen neuen       Azofarbstoff    herstellen kann, wenn man       rIas        4-Oxynaphi-alin-l-plienylketoii    mit     di-          azotiertem        4-Chlor-2-amino-phenylbenzyläther     kuppelt.

   Der neue Farbstoff bildet ein in       M'asser    unlösliches, dunkelrotes Pulver;     auf          ,oe(eio,neter    Unterlage hergestellt, erzeugt er       I        ez          feuriae    rote, Töne,  <I>Beispiel:</I>  <B>23,8</B> Teile     4-Oxynaphtalin-l-phenylkeion     werden in<B>500</B> Teilen Wasser unter Zusatz  von 4 Teilen     Ät7natron    gelöst.

   Hierauf fügt       iii.in    noch 20 Teile Soda hinzu und versetzt       init    einer aus 24,3 Teilen -t-Chlor-2-amiilo-         phenylbenzylät-'her    bereiteten     Diazolbsung.     Der gebildete Farbstoff scheidet sich sofort  als hochroter Niederschlag aus.



  Additional patent to main patent no. <B> 99522. </B> Process for the production of a new azo dye. It has been found that a new azo dye can be produced by coupling rIas 4-Oxynaphi-alin-1-plienylketoii with azo-azotized 4-chloro-2-aminophenylbenzyl ether.

   The new dye forms a dark red powder which is insoluble in mass; on, oe (eio, neter base produced, it produces I ez feuriae red, tones, <I> Example: </I> <B> 23.8 </B> parts of 4-oxynaphthalene-l-phenylkeion are used in <B > 500 parts of water are dissolved with the addition of 4 parts of sodium hydroxide.

   Then iii.in adds 20 parts of soda and mixed with a diazole solution prepared from 24.3 parts of -t-chloro-2-amilophenylbenzyl ether. The dye formed separates out immediately as a crimson precipitate.
