Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          3-Amino-phthalsäure-N-ss-phenyläthylenimid     mit dem     2,3-Oxynaphthoesäureanilid    vereinigt.  



  Der neue     Farbstoff    bildet ein orangerotes,  in Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle, hergestellt,  färbt er diese in echten orangen Tönen.  



       Beispiel;     26,6 Teile des     3-Amino-phthalsäure-N-ss-          phenyläthylenimids    werden wie üblich     diazo-          tiert    und in eine Lösung von 26,3 Teilen     2,3-          Oxynaphthoesäureanilid,    40 Teilen 30      /oiger          Natriumhydroxydlösung,    15 Teilen Soda in  1000 Teilen Wasser eingetragen. Der gebil-         dete    Farbstoff fällt sofort aus. Der orange  rote Niederschlag wird filtriert und getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 3-amino-phthalic acid-N-ß-phenylethyleneimide is combined with 2,3-oxynaphthoic anilide.



  The new dye forms an orange-red powder that is insoluble in water. On suitable substrates, such as. B. cotton, he dyes them in real orange tones.



       Example; 26.6 parts of 3-aminophthalic acid-N-ss-phenylethyleneimide are diazo- tated as usual and dissolved in a solution of 26.3 parts of 2,3-oxynaphthoic anilide, 40 parts of 30% sodium hydroxide solution, 15 parts of soda in 1000 parts Water entered. The dye formed precipitates immediately. The orange-red precipitate is filtered and dried.
