Description

  

  Zusatzpatent zum Hauptpatent Nr. 310830    Verfahren zur Herstellung eines wasserunlöslichen     Disazofarbstoffes       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines  wasserunlöslichen     Disazofarbstoffes,    welches  dadurch gekennzeichnet ist, dass man die       Tetrazoverbindung    von     4,4'-Diamino-3,3'-di-          chlordiphenyl    mit 1-     Acetoacetylamino    - 2     -          I,lienoxj7benzol    kuppelt.  



  <I>Beispiel</I>  50,6 Gewichtsteile     4,4'-Diamino-3,3'-di-          chlordiplienyl    werden mit 600     Volumteilen     Wasser und 270     Volumteilen        5n-Salzsäure     verrührt, dann mit Eis auf 0  C gekühlt und  mit 52,5     Volumteilen    40%iger     Natriumnitrit-          lösung    bei 0  C     tetrazotiert.    Die geklärte     Te-          trazolösung    wird bei 25  C mit einer essig  sauren,

   in Gegenwart von     Oley        lmethyltaurid     erhaltenen feinen Suspension von 110     Ge-          wiclitsteilen    1-     Acetoacetylamino-2-phenoxy-          benzol    zum.     Disazofarbstoff    gekuppelt. Der ge  bildete Farbstoff wird abgesaugt, neutral ge  waschen und getrocknet. Die Kupplung kann    mit Vorteil auch in Gegenwart von Harzseife  durchgeführt werden.  



  Das so erhaltene Produkt ist ein grün  stichig gelbes Pulver von grosser Farbstärke  und guter Lichtechtheit, das zum Färben von  Kunststoffen und für den graphischen Druck  sowie für spezielle Gebiete der Lack-,     Tapeten-          und    Papierindustrie verwendet werden kann.



  Additional patent to main patent No. 310830 Process for the production of a water-insoluble disazo dye The subject of the present additional patent is a process for the production of a water-insoluble disazo dye, which is characterized in that the tetrazo compound of 4,4'-diamino-3,3'-di chlorodiphenyl couples with 1-acetoacetylamino-2-l, lienoxj7benzene.



  <I> Example </I> 50.6 parts by weight of 4,4'-diamino-3,3'-dichlorodiplienyl are stirred with 600 parts by volume of water and 270 parts by volume of 5N hydrochloric acid, then cooled with ice to 0 ° C. and with 52 , 5 parts by volume of 40% sodium nitrite solution tetrazotized at 0 C. The clarified tetrazole solution is mixed with a vinegar-acidic,

   fine suspension of 110 parts by weight of 1-acetoacetylamino-2-phenoxybenzene obtained in the presence of olley methyl tauride. Disazo dye coupled. The dye formed is filtered off with suction, washed neutral and dried. The coupling can also be carried out with advantage in the presence of resin soap.



  The product thus obtained is a green, pungent yellow powder of great color strength and good lightfastness, which can be used for coloring plastics and for graphic printing as well as for special areas of the paint, wallpaper and paper industry.
