Description

  

      Zusatzpatent    zum Hauptpatent     Nr.185146.       Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          4-Amino-5-äthoxy-,Q-oxmethyl-4'-cblor-1,1'-          azobenzol    mit dem     o-Anisidid    der     2.3-Oxy-          naphthoe8äure    vereinigt. Der neue Farbstoff  stellt einen     bordenux-roten        Niedersehlag    dar.

    Auf geeigneten Substraten, wie zum Beispiel  Baumwolle, hergestellt, färbt er diese in  bordeauxroten Tönen mit vortrefflichen Echt  heitseigenschaften.         Beispiel:       35 Teile     4-Amino-5-äthoxy-ss-oxmethyl-4'-          chlor-1,1'-azobenzol    werden wie üblich     dia-          zotiert    und in eine Lösung von 29,3 Teilen       2,3-Oxynaphthoesäure-2'-methoxyanilid,    50  'feilen 30     "/oiger    Natronlauge, 30 Teilen Soda  und 2000 Teilen Wasser eingetragen. Der    gebildete Farbstoff fällt sofort aus. Der  bordeauxrote Niederschlag wird filtriert und  getrocknet.



      Additional patent to main patent number 185146. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 4-amino-5-ethoxy-, Q-oxmethyl-4'-cblor-1,1'-azobenzene is combined with the o-anisidide of 2,3-oxynaphthoic acid . The new dye is a bordenux-red lower layer.

    Produced on suitable substrates such as cotton, he dyes them in burgundy shades with excellent authenticity properties. Example: 35 parts of 4-amino-5-ethoxy-ss-oxmethyl-4'-chloro-1,1'-azobenzene are diazotized as usual and dissolved in a solution of 29.3 parts of 2,3-oxynaphthoic acid-2 ' methoxyanilide, 50 'filing 30 "/% sodium hydroxide solution, 30 parts of soda and 2000 parts of water. The dye formed precipitates immediately. The burgundy precipitate is filtered and dried.
