Description

  

      Zusatzpatent    zum Hauptpatent Nr. 182720.         Verfahren    zur Herstellung eines neuen     Azofarbstoifes.       Es wurde gefunden, dass man einen     Azo-          farbstoff    erhält, wenn man     diazotierten        4-          Ch        lor-2-amino-3'-trifluormethyl-1,1'-        diphenyl-          äther        finit        2,3-Oxynaphthoesäure-4'-methoxy-          anilid    vereinigt.

   Der neue     Farbstoff    bildet  ein rotes, in Wasser unlösliches Pulver. Auf  geeigneten Substraten, wie zum Beispiel  Zellulose, hergestellt, färbt er diese in schar  lachroten Tönen von sehr guten Echtheits  eigenschaften.    <I>Beispiel:</I>    28,7 'feile     4-Chlor-2-amitio-3'-triflLiorme-          thy    1-1,1-     diphenyläther    werden in üblicher  Weise     diazotiert.    Die erhaltene klare     Diazo-          lösung    wird in eine Lösung bestehend aus  29,3 Teilen     2,3-Oxyciaphthoesäure-4'-methoxy-          anilid,

      50 Teilen 30     o/oiger    Natriumhydroxyd-         lösung,    15 Teilen Natriumkarbonat und 2000  Teilen Wasser eingetragen. Der gebildete       Farbstoff    fällt sofort aus. Der rote Nieder  sehlag wird filtriert und getrocknet.



      Additional patent to main patent no. 182720. Process for the production of a new azo dye. It has been found that an azo dye is obtained if diazotized 4-chloro-2-amino-3'-trifluoromethyl-1,1'-diphenyl ether finite 2,3-oxynaphthoic acid-4'-methoxy anilide united.

   The new dye forms a red powder that is insoluble in water. Produced on suitable substrates, such as cellulose, for example, he dyes them in sharp, laugh red tones with very good fastness properties. <I> Example: </I> 28.7 'files 4-chloro-2-amitio-3'-triflloromethy 1-1,1-diphenyl ethers are diazotized in the usual way. The clear diazo solution obtained is converted into a solution consisting of 29.3 parts of 2,3-oxyciaphthoic acid-4'-methoxy anilide,

      50 parts of 30% sodium hydroxide solution, 15 parts of sodium carbonate and 2000 parts of water were added. The dye formed precipitates immediately. The red precipitate is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man diazotierten 4-Chlor-2-amino-3'-trifluor- methyl - 1,1' - diphenyläther mit 2,3 - Oxy - naphthoesäure-4'-methoxyanilid vereinigt. Der neue Farbstoff bildet ein rotes, in Wasser unlösliches Pulver. Auf geeigneten Substraten, wie zum Beispiel Zellulose, hergestellt, färbt er diese in scharlachroten Tönen mit sehr guten Echtheitseigenschaften. Claim: Process for the production of a new azo dye, characterized in that diazotized 4-chloro-2-amino-3'-trifluoromethyl-1,1'-diphenyl ether is combined with 2,3-oxynaphthoic acid-4'-methoxyanilide . The new dye forms a red powder that is insoluble in water. Produced on suitable substrates such as cellulose, for example, he dyes them in scarlet shades with very good fastness properties.
