  Zusatzpatent zum Hauptpatent     Nr.    214909.<B>'</B>    Verfahren zur Darstellung eines neuen     Anthrachinonfarbstoffes.       Das vorliegende Patent betrifft ein Ver  fahren zur Darstellung eines neuen     Anthra-          chinonfarbstoffes    und ist dadurch gekenn  zeichnet,     dass    man     1-amino-4-bromanthra-          chinan-2-sulfosaures    Natrium mit     4-Amino-2-          (methylacetylamino)-toluol    kondensiert.  



  Der neue Farbstoff besitzt die     Farmel     
EMI0001.0011     
    und färbt Wolle in saurem Bade in     rotstichig     blauen Tönen. Er besitzt gute Echtheitseigen  schaften und ein gutes     Egalisierungsver-          mögen.       <I>Beispiel:

  </I>  In<B>150</B> Gewichtsteilen Wasser und<B>50</B> Ge  wichtsteilen Alkohol werden 20 Gewichts-    teile     1-amino-4-bromanthrachinon-2-sulio-          saures    Natrium,<B>15</B> Gewichtsteile     4-Amino-2-          (methylacetylamino)-toluol,   <B>10</B>     Gewielltsteile          Natriumbiearbonat    und<B>0,3</B>     Gewichtsteile     Kupfer unter Rühren mehrere Stunden auf  <B>70'</B> erhitzt, bis eine Probe in Wasser gelöst  keine     Farbvertiefung    mehr anzeigt. Nach  beendeter Kondensation wird der Alkohol ab  getrieben.

   Der Farbstoff wird     abfiltriert    und  mit verdünnter     Kochsalzlösung    gewaschen  und getrocknet.  



  Der Farbstoff besitzt die Formel  
EMI0001.0025     
    und färbt; Wolle     in    saurem Bade in     rotstiellig     blauen Tönen. Er besitzt gute Echtheits-           eigensehaften    und ein gutes     E"#,-alisierungs-          vermögen.  



  Additional patent to main patent no. 214909. <B> '</B> Process for the preparation of a new anthraquinone dye. The present patent relates to a process for the preparation of a new anthracinone dye and is characterized in that 1-amino-4-bromoanthracinane-2-sulfonic acid sodium is condensed with 4-amino-2- (methylacetylamino) toluene.



  The new dye owns the Farmel
EMI0001.0011
    and dyes wool in an acid bath in shades of reddish blue. It has good authenticity properties and a good leveling ability. <I> example:

  </I> In <B> 150 </B> parts by weight of water and <B> 50 </B> parts by weight of alcohol, 20 parts by weight of 1-amino-4-bromoanthraquinone-2-sulphate sodium, <B> 15 parts by weight of 4-amino-2- (methylacetylamino) toluene, 10 parts by weight of sodium carbonate and 0.3 parts by weight of copper for several hours to <B> 70 '</B> heated until a sample dissolved in water no longer shows any deepening of color. After the condensation has ended, the alcohol is driven off.

   The dye is filtered off, washed with dilute sodium chloride solution and dried.



  The dye has the formula
EMI0001.0025
    and colors; Wool in an acid bath in shades of red and blue. It has good authenticity properties and a good ability to identify.
