Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>152883.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    der Formel  
EMI0001.0005     
    erhält, wenn man den     4.4'-Dichlor-2-diazo-          1   <B>.</B>     l-diphenyläther    mit dem     o-Anisidid    der  2.     S-Oxynaphthoesäure    kuppelt.  



  Der so erhaltene Farbstoff bildet ein hell  rotes Pulver. Auf geeigneten Substraten, wie  zum Beispiel Baumwolle, hergestellt, färbt  er diese in leuchtenden, ausserordentlich  echten Tönen.    <I>Beispiel:</I>  25,4 Teile 4.     4'-Dichlor-2-amino-1   <B>.</B>     l'-di-          phenyläther    werden wie üblich     diazotiert    und    in eine     LösUDg    Voll<B>29,3</B> Teilen des     o-Ani-          sidids    der 2.

       3-Oxynaphthoesäure,   <B>60</B> Teilen       30        %iger        Natronlauge,        15        Teilen        Soda        und     2000 Teilen Wasser eingetragen. Der ge  bildete Farbstoff fällt sofort aus. Er wird  filtriert, gewaschen und getrocknet.



  Additional patent to main patent no. <B> 152883. </B> Process for the production of a new azo dye. It has been found that a new azo dye of the formula
EMI0001.0005
    obtained when the 4.4'-dichloro-2-diazo-1 <B>. </B> l-diphenyl ether is coupled with the o-anisidide of the 2nd S-oxynaphthoic acid.



  The dye thus obtained forms a light red powder. Produced on suitable substrates, such as cotton, for example, he dyes them in bright, extraordinarily real tones. <I> Example: </I> 25.4 parts of 4. 4'-dichloro-2-amino-1 <B>. </B> l'-diphenyl ethers are diazotized as usual and dissolved in a full solution > 29.3 </B> parts of the o-anisidide of the 2nd

       3-oxynaphthoic acid, 60 parts of 30% strength sodium hydroxide solution, 15 parts of soda and 2000 parts of water were added. The dye formed precipitates out immediately. It is filtered, washed and dried.
