Description

  

      Zusatzpatent    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-Oxyaminoanthrachinon    auf  einander einwirken lässt.  



  Das neue. Produkt bildet in trockenem  Zustande ein rotviolettes Pulver, das in  Wasser leicht löslich ist und     Acetatseide    in  klaren     violettroten    Tönen färbt.    <I>Beispiel</I>  5 Teile     1,4-Ogyaminoanthrachinon    werden,  am besten in Form einer konzentrierten  Paste, mit 15 Teilen     Benzaldehyd,    70 Teilen       Bisulfit    und 50 Teilen Wasser unter Rühren    auf 95  erwärmt, bis eine Probe in     Wasser     klar löslich ist. Man dampft zur Trockne ein.



      Additional patent to main patent number 131100. Process for the preparation of a new product which can be used as a dye. It has been found that a new product is obtained if benzaldehyde, bisulfite and 1,4-oxyaminoanthraquinone are allowed to act on one another.



  The new. When dry, the product forms a red-violet powder that is easily soluble in water and dyes acetate silk in clear violet-red tones. <I> Example </I> 5 parts of 1,4-ogyaminoanthraquinone, ideally in the form of a concentrated paste, are heated to 95 with 15 parts of benzaldehyde, 70 parts of bisulfite and 50 parts of water while stirring until a sample is clearly soluble in water is. It is evaporated to dryness.
