Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 159410.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen zur  Herstellung von egalen Färbungen auf aus       Viskoseseide    bestehender     Stückwäre    besonders  geeigneten neuen     Azofarbstoff    erhält, wenn  man 1     Mol        tetrazotiertes        4,4'-Diamino-3-3'-          dimethoxydiplienyl    mit 1     Mol    der 1-     Oxy-          iiaphthalin-4,

  8-disulfonsäure    mit 1     .1!2o1    der     1-          Ainino-8-oxynaplithalin-4-sulfonsäure    kuppelt.  



  Der neue Farbstoff stellt ein dunkles  Pulver dar, das sich in Wasser mit reiner  blauer Farbe löst. Er erzeugt auf Baumwolle  oder Kunstfasern     aus    regenerierter Zellulose  reine blaue Töne.  



  <I>Beispiel:</I>  Die in gewohnter Weise hergestellte       Tetrazoverbindung    aus 244 Gewichtsteilen       3,3'-Diinetlioxy-4,4'-diaminodiphenyl    wird in       sodaalkalischer    Lösung vereinigt mit 304  Gewichtsteilen     1-Oxynaphthalin-4,8-disulfon-          säure    und nach stattgefundener Kupplung    mit 239 Gewichtsteilen     1-Amino-8-oxynaph-          thalin-4-sulfonsäure.    Nach erfolgter Kupplung  wird der gebildete Farbstoff durch Erwärmen  und     Aussalzen    isoliert, filtriert und getrocknet.



  <B> Additional patent </B> to main patent no. 159410. Process for the production of a new azo dye. It has been found that a new azo dye which is particularly suitable for producing level dyeings on pieces made of viscose silk is obtained if 1 mole of tetrazotized 4,4'-diamino-3-3'-dimethoxydiplienyl is obtained with 1 mole of 1-oxy-iiaphthalene -4,

  8-disulfonic acid couples with 1 .1! 2o1 of 1-ainino-8-oxynaplithalin-4-sulfonic acid.



  The new dye is a dark powder that dissolves in water with a pure blue color. It creates pure blue tones on cotton or synthetic fibers from regenerated cellulose.



  <I> Example: </I> The tetrazo compound prepared in the usual way from 244 parts by weight of 3,3'-diinetlioxy-4,4'-diaminodiphenyl is combined in a soda-alkaline solution with 304 parts by weight of 1-oxynaphthalene-4,8-disulfonic acid and after coupling has taken place with 239 parts by weight of 1-amino-8-oxynaphthalene-4-sulfonic acid. After coupling has taken place, the dye formed is isolated by heating and salting out, filtered and dried.
