Description

  

      Zusatzpatent    zum Hauptpatent Nr. 99522.    Verfahren zur Herstellung eines neuen     Azofarlostoffes.            Es     wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man das     Arylid     aus     2,3-Oxynaphthoesäure    und     2-ATnitio-1,1'-          diphenyläther    mit     diazotiertem        4-Chlor-2-          amino-1,1'-diphenyläther    kuppelt. Der neue  Farbstoff bildet ein in     Wasser    unlösliches,  dunkelrotes Pulver.

   Auf der Faser oder einem  geeigneten Substrat hergestellt, erzeugt er  reisrote Töne.  



       Beispiel:     35,4 Teile     2,3-Oxynaphthoesäure    werden  in 500 Teilen Wasser unter Zusatz von  4 Teilen     Ätznatron    gelöst. Hierauf fügt man  noch 20 Teile Soda hinzu und versetzt mit  einer aus 21,9 Teilen 4-Chlor-2-amino-1,1'-         diphenyläther    bereiteten     Diazolösung.    Der  gebildete Farbstoff scheidet sich sofort als  roter Niederschlag aus.



      Additional patent to main patent no. 99522. Process for the production of a new azo-fur. It has been found that a new azo dye is obtained when the arylide of 2,3-oxynaphthoic acid and 2-ATnitio-1,1'-diphenyl ether is coupled with diazotized 4-chloro-2-amino-1,1'-diphenyl ether. The new dye forms a water-insoluble, dark red powder.

   Made on fiber or a suitable substrate, it creates rice red tones.



       Example: 35.4 parts of 2,3-oxynaphthoic acid are dissolved in 500 parts of water with the addition of 4 parts of caustic soda. 20 parts of soda are then added and a diazo solution prepared from 21.9 parts of 4-chloro-2-amino-1,1'-diphenyl ether is added. The dye formed separates out immediately as a red precipitate.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man das Arylid aus 2,3-Oxysaphthoesäure und 2-Amino-1,1'-diphenyläther mit diazo- tiertem 4- Chlor - 2 - amino -1,1' - diphenyläther kuppelt. Der neue Farbstoff bildet ein in Wasser unlösliches, dunkelrotes Pulver. Auf der Faser oder einem geeigneten Substrat hergestellt, erzeugt er reisrote Töne. PATENT CLAIM: Process for the preparation of a new azo dye, characterized in that the arylide of 2,3-oxysaphthoic acid and 2-amino-1,1'-diphenyl ether is mixed with diazotized 4-chloro - 2 - amino -1,1 '- diphenyl ether couples. The new dye forms a water-insoluble, dark red powder. Made on fiber or a suitable substrate, it creates rice red tones.
