Description

  

  Zusatzpatent zum Hauptpatent     Nr.    163542.    Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  metallhaltigen Farbstoff erhalten kann, wenn  man den     Azolarbstoff    aus     diazotierter        4-Sulfo-          2-aminobenzol-l-karboiisäure    und.     1-(2'-Chlor-          5'-,3ulfo-)-3-methyl-5-pyrazolon    mit     ehromab-          gebenden    Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkelgelbes Pulver dar, das sich in     Was-          Her,        in        10        %iger        Sodalösung,        in        10        %iger        Na-          tronlauge,    sowie in konzentrierter Schwefel  säure mit gelber Farbe löst und Wolle aus  saurem Bade in     rötliebgelben    Tönen von sehr  guter Lichtechtheit färbt.  



  <I>Beispiel:</I>  Man löst<B>25,3</B> Teile des     Azofarbstoffes    aus       diazotierter        4-Sulfo-2-aminobenzol-l-karboti-          säure    und     1-(2'-ChIor-5'-sulio-)-3-methyl-5-          pyrazolon    in etwa 200 Teilen Wasser und  kocht nach Zusatz von 4,6 Teilen     Ohromoxyd     in Form einer     Ohromsulfatlösung    mehrere    Stunden unter     Rückfluss.    Der     chromierte    Farb  stoff wird     ausgesalzen    und getrocknet.



  Additional patent to main patent No. 163542. Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye can be obtained if the azo material is obtained from diazotized 4-sulfo-2-aminobenzene-1-carbonic acid and. 1- (2'-chloro-5 '-, 3ulfo -) - 3-methyl-5-pyrazolone treated with Ehromab- donating agents.



  The metal-containing dye obtained is a dark yellow powder that dissolves in Washer, in 10% sodium carbonate solution, in 10% sodium hydroxide solution, and in concentrated sulfuric acid with a yellow color, and wool from an acid bath in reddish yellow tones of very good lightfastness.



  <I> Example: </I> <B> 25.3 </B> parts of the azo dye are dissolved from diazotized 4-sulfo-2-aminobenzene-1-carbotic acid and 1- (2'-chloro-5 ' -sulio-) - 3-methyl-5-pyrazolone in about 200 parts of water and, after adding 4.6 parts of ohromoxide in the form of an ohromulfate solution, boils under reflux for several hours. The chrome-plated dye is salted out and dried.
