  Zusatzpatent zum     Ilauptpatent        Nr.    101614.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    erhält, wenn man das     1-Oxy-          iiitplithalin-5-suliamid    mit     diazotierter        1-          .\-mino-2-oxybenzol-4-sulfosäure    kuppelt.

    Der neue Farbstoff bildet ein     schwärzlich-          braunes    Pulver und färbt Wolle im essig  sauren Bade in blauroten Farbtönen, welche  beim     Naelichramieren    blau, beim Nach  kupfern rotviolett und echt werden.  



  <I>Beispiel:</I>       92,3    Teile     1-Oxyntiphthalin-5-sulfimi(1     werden in eine Lösung von<B>56</B> Teilen     Atz-          hali    in 48 Teilen Wasser bei<B>20-25 '</B>     einge-          tra-en.    Es entsteht eine breiige Suspension,  die man bei derselben Temperatur mit<B>25</B> Tei  len der     Natriumverbindung    der     diazotierten          1-Amino-2-oxybenzol-4-si,tlfosäure    auf einmal    versetzt.

   Man rührt bis die     Di"#tzoverbinduiig     verschwunden ist.     Tlierauf    verdünnt     man    mit  <B>150</B> Teilen Wasser, giesst in<B>280</B> Teile     lä%ige     Salzsäure und färbt den Farbstoff durch Zu  satz von Kochsalz aus.



  Additional patent to the main patent No. 101614. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if the 1-oxy-iiitplithalin-5-suliamide is coupled with diazotized 1-. \ - mino-2-oxybenzene-4-sulphonic acid.

    The new dye forms a blackish-brown powder and dyes wool in an acidic bath in blue-red hues, which become blue when naelichraming, red-violet and real when copper is applied.



  <I> Example: </I> 92.3 parts of 1-oxyntiphthalene-5-sulfimi (1 are dissolved in a solution of <B> 56 </B> parts of Atzhali in 48 parts of water at <B> 20-25 A pulpy suspension is formed, which is mixed with 25 parts of the sodium compound of the diazotized 1-amino-2-oxybenzene-4-sulfo acid at the same temperature moved at once.

   The mixture is stirred until the di "tzo compound has disappeared. It is then diluted with 150 parts of water, poured into 280 parts of molten hydrochloric acid, and the dye is colored by adding sodium chloride out.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofa,rbstoffes, dadurch gekennzeichnet, dass man das 1-Oxynaplithalin-5-sulfamid mit dia- zetierter 1-Amino,-2-oxybenzol-4-sulfosäur(- kuppelt. Der neue Farbstoff bildet ein schwärzlielibra.unes Pulver und färbt Wolle im essigsauren Bade in blauroten Farbtönen, welche beim Naehehromieren blau, beim Nachkupfern rotvioleit und echt werden. PATENT CLAIM: Process for the production of a new azo dye, characterized in that the 1-oxynaplithalin-5-sulfamide is coupled with diacetated 1-amino, -2-oxybenzene-4-sulfonic acid (-. The new dye forms a blackish-white libra .unes powder and dyes wool in the acetic acid bath in blue-red shades, which become blue when chromed close, and red-violet and real when re-coppering.
