Description

  

  <B>Zusatzpatent</B> 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     Azofarbstoff    aus     diazotierter        4-Sulfo-          2-aminobenzol-l-karbonsäure    und     1-(4'-Sulfo-)-          phenyl-3-methyl-5-pyrazolon    mit chromabge  benden Mitteln behandelt.  



  Der erhaltene metallhaltige Farbstoff stellt  ein dunkelgelbes Pulver dar, das sich in  Wasser mit gelber Farbe löst     uud    Wolle aus  saurem Bade in gleichmässigen,     rötlichgelben     Tönen färbt, die vorzüglich licht-, sowie gut       walkecht    sind.  



  <I>Beispiel:</I>  Eine konzentrierte wässerige Lösung von  22,9 Teilen des     Azofarbstoffes    aus     diazotierter          4-Sulfo-2-anririobenzol-l-karbonsäure    und 1  (4'-Sulfo-)hhenyl-     3-methyl    - 5     -pyrazolon    wird  mit 4,6 Teilen Chromoxyd in Form von     Chromi-.          oxalat    mehrere Stunden unter Rückfuss zum    Sieden erhitzt. Das vom Farbstoff nicht auf  genommene Chrom wird durch     Alkalizusatz     entfernt und das     Filtratzur    Trockne verdampft.



  <B> Additional patent </B> 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 dye is obtained from diazotized 4-sulfo-2-aminobenzene-1-carboxylic acid and 1- (4'-sulfo -) - phenyl-3-methyl-5-pyrazolone treated with chromium-releasing agents.



  The metal-containing dye obtained is a dark yellow powder which dissolves in water with a yellow color and dyes wool from an acidic bath in uniform, reddish-yellow shades which are excellent lightfast and good millfast.



  <I> Example: </I> A concentrated aqueous solution of 22.9 parts of the azo dye from diazotized 4-sulfo-2-anriiobenzene-1-carboxylic acid and 1 (4'-sulfo-) hhenyl-3-methyl - 5 - Pyrazolon is with 4.6 parts of chromium oxide in the form of Chromi-. oxalate heated to boiling under reflux for several hours. The chromium not absorbed by the dye is removed by adding alkali and the filtrate is evaporated to dryness.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes, dadurch gekenn zeichnet, dass man den Azofarbstoff aus di- azotierter 4 - Sulfo - 2 - aminoberrzol -1- karbon- säure und 1-(4'-Sulfo-)phenyl-3-methyl-5-pyra- zolon reit chromabgebenden Mitteln behandelt. PATENT CLAIM: Process for the production of a new metal-containing dye, characterized in that the azo dye is made from diazotized 4 - sulfo - 2 - aminoberrzol -1-carbonic acid and 1- (4'-sulfo-) phenyl-3-methyl -5-pyrazolone treated with chromium-releasing agents. Der erhaltene metallhaltige Farbstoff stellt ein dunkelgelbes Pulver dar, das sich in Wasser mit gelber Farbe löst und Wolle aus saurem Bade in gleichmässigen, rötlichgelben Tönen färbt, die vorzüglich liebt-, sowie gut walkecht sind. The metal-containing dye obtained is a dark yellow powder which dissolves in water with a yellow color and dyes wool from an acidic bath in uniform, reddish-yellow shades that are excellently love-resistant and are also easy to knead.
