Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          3-Ami        no-phthalsäure-N-P-phenyläthylenimid     mit dem     2,3-Oxynaphthoesäure-2'-methoxy-          anilid    vereinigt.  



  Der neue Farbstoff bildet ein orangerotes,  in Wasser unlösliches Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle, hergestellt,  färbt er diese in echten orangeroten Tönen.    <I>Beispiel;</I>    26,6 Teile des     3-Amino-phthalsäure-N-p-          phenyläthylenimids    werden wie üblich     diazo-          tiert    und in eine Lösung von 29,3 Teilen     2,3-          Oxynaphthoesäure-2'-methoxyanilid,    40 Teilen  30     o/oiger        Natriumhydroxydlösung,   <B>15</B> Teilen  Soda in 1000 Teilen Wasser eingetragen. Der    gebildete     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-P-phenylethyleneimide is combined with 2,3-oxynaphthoic acid-2'-methoxyanilide.



  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-red tones. <I> Example; </I> 26.6 parts of 3-aminophthalic acid-Np-phenylethyleneimide are diazotized as usual and dissolved in a solution of 29.3 parts of 2,3-oxynaphthoic acid-2'-methoxyanilide, 40 Parts of 30% sodium hydroxide solution, 15 parts of soda added to 1000 parts of water. The dye formed precipitates immediately.

   The orange-red precipitate is filtered and dried.
