Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 131100.    Verfahren zur Herstellung eines neuen, als Farbstoff verwendbaren Produktes.    Es wurde gefunden, dass man ein neues  Produkt erhält, wenn man     Benzaldehyd,          Bisulfit    und     1,4-Diaminoarrthrachinon    aufein  ander einwirken lässt.  



  Das neue Produkt bildet in trockenem  Zustande ein dunkelviolettes, in Wasser  leicht mit rein violetter Farbe lösliches Pul  ver. Aus seiner Lösung kann die     Acetatseide     in echten violetten Tönen gefärbt werden.  



  <I>Beispiel:</I>  10 Teile     1,4-Dianrirroarrthrachinon    werden  mit 15 Teilen     Benzaldehyd,    75 Teilen einer  zirka     40-volumprozentigen        Natriumbisulfit-          lösung    und 50 Teilen Wasser zirka 1 Stunde    unter Rühren auf<B>901</B> erhitzt, wobei alles in  Lösung geht. Man dampft zur Trockne ein.



  <B> Additional patent </B> to main patent no. 131100. Process for the production of a new product that can be used as a dye. It has been found that a new product is obtained when benzaldehyde, bisulfite and 1,4-diaminoarrthraquinone are allowed to act on one another.



  When dry, the new product forms a dark violet powder that is easily soluble in water with a pure violet color. The acetate silk can be dyed in real violet tones from its solution.



  <I> Example: </I> 10 parts of 1,4-dianrirroarrthraquinone are mixed with 15 parts of benzaldehyde, 75 parts of an approximately 40 percent by volume sodium bisulfite solution and 50 parts of water to <B> 901 </B> for about 1 hour while stirring heated, with everything going into solution. It is evaporated to dryness.
