Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>162883-</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    der Formel-.  
EMI0001.0005     
    erhält, wenn man den     4-Ohlor-4'-methoxy-          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>  24,9 Teile     4-Cblor-4'-methoxy-2-amino-          1   <B>.</B>     l'-diphenyläther    werden wie üblich diazo-         tiert    und in eine Lösung von<B>29,3</B> Teilen  des     o-Anisidids    der 2.     3-Oxynaphthoesäure,     <B>60</B> Teilen<B>30</B>     '/oiger    Natronlauge,<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. <B> 162883- </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-chloro-4'-methoxy-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> 24.9 parts of 4-chloro-4'-methoxy-2-amino-1 <B>. </B> l'-diphenyl ether are diazo- tated as usual and converted into a solution of <B> 29.3 </B> parts of the o-anisidide of the 2nd 3-oxynaphthoic acid, <B> 60 </B> parts <B> 30 </B> '/ oiger sodium hydroxide, <B> 15 </ B> parts of soda and 2000 parts of water entered. The dye formed precipitates immediately. It is filtered, washed and dried.
