  Zusatzpatent zum Hauptpatent     Nr.   <B>107394.</B>    Verfahren     zur*    Herstellung eines     Farbstöffes.       Es wurde gefunden,     dass    man einen  neuen Farbstoff erhält,     weleher    in     essio,-          -m    Bade eine     überrasühende,    Affinität       ,daure     zur     Aoetylzellulose    besitzt, wenn man     di-          azotierte        --Nitranilin-4-sulfosäure    mit     Di-          phenylamin    kuppelt.

   Der Farbstoff stellt  ein dunkles Pulver dar und färbt aus essig  saurem     Ba3de        Acetaiseide    in     hervorrauend          lieliteehtgn    orangeroten Tönen an.  



  <I>Beispiel:</I>  2940 Teile     2#-nitranilin-4-sulfosaures    Na  trium werden in bekannter Weise mit<B>69</B>  Teilen     Natriumnitrit    und<B>250</B> Teilen     Salz-          särtre        cliazotiert.    Die     Diazolösung    wird     un-          tcr    Rühren in eine wässerige Emulsion von  <B>169</B> Teilen     Diphenylamin    eingetragen. Man    rührt noch einige Zeit, indem man die Mine  ralsäure mit     Natriumacetat    abstumpft, er  wärmt dann auf     ea.   <B>60</B> bis<B>8G'</B> und filtriert.

    Zur Reinigung kann der Farbstoff als     Al-          kalisalz    aus Wasser Umgelöst werden.



  Additional patent to main patent no. <B> 107394. </B> Process for the * production of a dye. It has been found that a new dye is obtained which, in essence, has an overwhelming affinity for aoetyl cellulose in the bath when diazotized --nitraniline-4-sulfonic acid is coupled with diphenylamine.

   The dye is a dark powder and stains from acetic acid Ba3de Acetai silk in excellent, lieliteehtgn orange-red tones.



  <I> Example: </I> 2940 parts of 2 # -nitraniline-4-sulfo acid sodium are cliazotized in a known manner with <B> 69 </B> parts of sodium nitrite and <B> 250 </B> parts of hydrochloric acid . The diazo solution is introduced into an aqueous emulsion of 169 parts of diphenylamine with stirring. The mixture is stirred for a while by dulling the mineral acid with sodium acetate, then warms it up to about <B> 60 </B> to <B> 8G '</B> and filtered.

    For cleaning, the dye can be redissolved from water as an alkali salt.
