Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoifes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          2.5-Dichlor-l-aminobenzol    mit dem     2-Oxy-          2'-phenyl-3.4-pseudonaphthazimid    vereinigt.  



  Der neue Farbstoff bildet ein oranges, in  Wasser     unlösliches    Pulver. Auf geeigneten  Substraten, wie z. B. Baumwolle, hergestellt,  färbt er diese in echten orangen Tönen.    <I>Beispiel:</I>    16.2 Teile des     2.5-Dichlor-l-aminobenzols     werden wie üblich     diazotiert    und in eine  Lösung von 26.1 Teilen     2-Oxy-2'-phenyl-3.4-          pseudonaphthazimid,    40 Teilen 30%iger Na  triumhydroxydlösung, 15 Teilen Soda und  1000 Teilen Wasser eingetragen. Der gebil-         dete    Farbstoff fällt sofort aus. Der orange       NTiederschlag        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 2,5-dichloro-1-aminobenzene is combined with 2-oxy-2'-phenyl-3,4-pseudonaphthazimide.



  The new dye forms an orange powder that is insoluble in water. On suitable substrates, such as. B. cotton, he dyes them in real orange tones. <I> Example: </I> 16.2 parts of 2.5-dichloro-1-aminobenzene are diazotized as usual and triumhydroxydlösung in a solution of 26.1 parts of 2-oxy-2'-phenyl-3.4-pseudonaphthazimid, 40 parts of 30% , 15 parts of soda and 1000 parts of water entered. The dye formed precipitates immediately. The orange N precipitate is filtered and dried.
