Description

  

      Zusatzpatent    zum Hauptpatent Nr. 161842.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    der Formel  
EMI0001.0004     
    erhält, wenn man den     Äthylester    des     2-Di-          azo-4-chloi--4'-carbonsäiire-1.1'-diphenyläthers     mit dem     P-Naphtylamid    der     2.3-Oxynaph-          thoesäure    kuppelt.  



  Der so erhaltene     Farbstoff    bildet ein rotes  Pulver. Auf geeigneten Substraten, wie zum  Beispiel Baumwolle, Wolle, Kunstseide, her  gestellt, färbt er diese in leuchtenden, sehr  echten, roten Tönen.  



  <I>Beispiel</I>  29,1 Teile des     Äthylesters    des     2-Amino-          4    -     chlor    - 4'-     carbonsäure    -1.1'-     diphenyläthers     werden wie üblich     diazotiert    und in eine Lö  sung von 31,3 Teilen des     ss    -     Naphtylamids     der 2 .     3-Oxynaphthoesäur    e, 60 Teilen 30  ; o-         iger        Natriiimhydi#oxydlösung,   <B>15</B> Teilen Soda  und 2000 Teilen Wasser eingetragen. Der  gebildete     Farbstoff    fällt sofort aus. Er wird  filtriert, gewaschen und getrocknet.



      Additional patent to main patent No. 161842. Process for the production of a new azo dye. It has been found that a new azo dye of the formula
EMI0001.0004
    obtained when the ethyl ester of 2-di-azo-4-chloi-4'-carboxylic acid-1,1'-diphenyl ether is coupled with the p-naphthylamide of 2,3-oxynaphthoic acid.



  The dye thus obtained forms a red powder. Made on suitable substrates, such as cotton, wool, rayon, he dyes them in bright, very real, red tones.



  <I> Example </I> 29.1 parts of the ethyl ester of 2-amino-4-chloro-4'-carboxylic acid -1.1'-diphenyl ether are diazotized as usual and dissolved in a solution of 31.3 parts of the ss-naphthylamide the second . 3-oxynaphthoic acid e, 60 parts 30; Oiger sodium hydroxide solution, 15 parts of soda and 2000 parts of water are added. The dye formed precipitates immediately. It is filtered, washed and dried.
