Description

  

      Verfahren    zur     Darstellunä    eines     Acetatseidenfarbstoffes.            Gegenstand    dieses Zusatzpatentes ist ein       Verfahren    zur Darstellung eines     Acetatseiden-          farbstoffes,    dadurch gekennzeichnet, dass man       1-Aininotiaplttalsä.ureatthydrid    mit     Anilin    kon  densiert.  



  <I>Beispiel:</I>  <B>25</B>     Gewichtsteile        4-Antinonaphtalsäureari-          hydrid    werden mit 400     Rauurteilen    Anilin  <B>zum</B> Sieden erhitzt unter     Rückfluss.    Nach  dem Absaugen. Waschen und Trocknen wird  ein     Farbstoff    erhalten, welcher bei ca. 290  C  schmilzt; ein gelbes Pulver darstellt und       Celluloseester.        -äther    oder deren     Umwand-          lungsprodukte    in sehr klaren,     grünstickig          selben    Tönen mit stark     -rüner    Fluoreszenz  färbt.



      Process for the preparation of an acetate silk dye. The subject of this additional patent is a process for the preparation of an acetate silk dye, characterized in that 1-ainotiaplttalsä.ureathydrid is condensed with aniline.



  <I> Example: </I> <B> 25 </B> parts by weight of 4-antinonaphthalic acid anhydride are heated to boiling under reflux with 400 rough parts of aniline. After suction. Washing and drying gives a dye which melts at about 290 C; represents a yellow powder and cellulose ester. -ether or its conversion products in very clear, greenish, same tones with strong -green fluorescence.
