Description

  

      Zusatzpatent    zum Hauptpatent     Nr.    193080.         Verfahren    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen Farb  stoff erhält, wenn man dianotierten     4-Chlor-          2-aminodiphenyläther    mit     5-Oxy-l-phenyl-4'-          methylazimidobenzol    vereinigt.  



  Der neue     Farbstoff    bildet ein scharlach  rotes, in Wasser unlösliches Pulver. Auf einem  geeigneten Substrat hergestellt, färbt er dieses  scharlachrot.  



  <I>Beispiel:</I>  <B>21,9</B> Teile     4-Chlor-2-aminodiphenyläther     werden wie üblich dianotiert und einer alka  lischen Lösung von 22,5 Teilen     5-Oxy-l-phenyl-          4'-methylazimidobenzol    langsam zugegeben.  Der gebildete     Farbstoff    fällt sofort als schar-    lachrot gefärbter Niederschlag aus. Er wird  filtriert und getrocknet.



      Additional patent to main patent No. 193080. Process for the production of a new dye. It has been found that a dye is obtained when dianotized 4-chloro-2-aminodiphenyl ether is combined with 5-oxy-1-phenyl-4'-methylazimidobenzene.



  The new dye forms a scarlet red powder that is insoluble in water. Produced on a suitable substrate, he colors it scarlet red.



  <I> Example: </I> <B> 21.9 </B> parts of 4-chloro-2-aminodiphenyl ether are dianotized as usual and an alkaline solution of 22.5 parts of 5-oxy-1-phenyl-4 '-methylazimidobenzene added slowly. The dye formed precipitates immediately as a sharp red colored precipitate. It is filtered and dried.
