  Zusatzpatent zum Hauptpatent     Nr.   <B>211661.</B>    Verfahren zur Herstellung eines     Polyazofarbstoffes.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     Polyazo-          farbstoffes.    Das Verfahren ist dadurch gekenn  zeichnet,     dass    man den     Aminodisazofarbstoff,     der durch Kuppeln von     diazotierter        1-Amino-          4-oxybenzol-3-earbonsäure    mit     1-Aminonaph-          thalin-6-sulfonsäure,

          Weiterdiazotieren    und  Kuppeln mit     4-Methoxy-2-amino-phenoxy-          essigsäure    erhältlich ist,     diazotiert    und mit       2-Phenylamino-   <B>5</B>     -oxynaphthalin-7-sulionsäure     kuppelt.  



  Der neue Farbstoff stellt ein dunkles     Pdl-          ver    dar, das sich in Wasser mit blauer Farbe  löst und Baumwolle     grünstichig    blau färbt;  die mit Kupfersalzen     nacUbehandelte,    Färbung  ist     grünstichig    marineblau und besitzt gute       Nass-    und Lichtechtheit.

  Additional patent to main patent no. <B> 211661. </B> Process for the production of a polyazo dye. The present patent relates to a process for the production of a polyazo dye. The process is characterized in that the amino disazo dye obtained by coupling diazotized 1-amino-4-oxybenzene-3-carboxylic acid with 1-aminonaphthalene-6-sulfonic acid,

          Further diazotization and coupling with 4-methoxy-2-aminophenoxyacetic acid is obtainable, diazotized and coupled with 2-phenylamino- <B> 5 </B> -oxynaphthalene-7-sulionic acid.



  The new dye is a dark powder that dissolves in water with a blue color and gives cotton a greenish blue; the dye, which has been treated with copper salts, is greenish navy blue and has good wet and light fastness.



  <I> Example: </I> The suspension of the diazo compound of the aminodisazo dye, which is produced by coupling diazotized 1-amino-4-oxybenzene-3-carboxylic acid with 1-aminonaplithalin-6-sulfonic acid, further diazotization and coupling with 4- Methoxy-2-a, mio-phenoxyacetic acid is obtainable, for the production of which <B> 6.9 </B> parts by weight of sodium nitrite are required,

   at <B> 50 </B> with stirring to dissolve <B> 32 </B> parts by weight of 2 phenylamino-5-oxynaphthalene-7-sulfonic acid and 25 parts by weight of anhydrous sodium carbonate in <B> 950 </ B > Give parts of water and keep the whole thing soda-alkaline during the coupling.



  The dye, which is separated off in the usual way, is a dark powder that dissolves in water with a blue color. The dye gives cotton a greenish blue. The dye after-treated with copper salts is navy blue with a greenish tinge and has good wet and light fastness.
