Description

  

      Zusatzpatent    zum Hauptpatent Nr. 162464.    Verfahren zur Herstellung eines in roten Tönen     färbenden    chromhaltigen Farbstoffes.    Es wurde gefunden, dass man einen in  roten Tönen färbenden chromhaltigen Farb  stoff erhalten kann, wenn man den     Azofarb-          stoff    aus     diazotierter    4 - Chlor -2-     amino        -1-          phenol-6-sulfonsäure    und     1-(4'-Sulfo-)rc-naph-          thyl    -3-     methyl    -5-     pyrazolon    mit chromab  gebenden Mitteln behandelt.  



  Der erhaltene chromhaltige Farbstoff  stellt ein braunrotes Pulver dar, das sich in  Wasser, 10%iger     Sodalösung    oder 10%iger  Natronlauge mit orangeroter und in konzen  trierter Schwefelsäure mit gelblicher Farbe  löst. Er färbt Wolle aus schwefelsaurem  Bade in gleichmässigen     gelbstichigroten    Tö  nen, die sehr gut licht- und     walkecht    sind.

    <I>Beispiel:</I>  Der aus 2.24 Teilen     4-Chlor-2-amino-l-          phenol-6-sulfonsäure    und 312 Teilen 1-(4'  Sulfo-)a-naphthyl-3-methyl-5-pyrazolon in  üblicher Weise hergestellte Farbstoff wird  in 10;000 Teilen Wasser und einer     Chromsul-          fatlösung,    die 84 Teile Chromoxyd enthält,    etwa 20 Stunden     unter        Rückfluss    zum Sieden  erhitzt. Die mit Kochsalz abgeschiedene  Chromverbindung des Farbstoffes wird ab  filtriert und getrocknet.



      Additional patent to main patent no. 162464. Process for the production of a chromium-containing dye which colors in red shades. It has been found that a chromium-containing dyestuff which turns red tones can be obtained if the azo dyestuff is obtained from diazotized 4-chloro -2-amino -1-phenol-6-sulphonic acid and 1- (4'-sulpho-) rc-naphthyl -3- methyl -5- pyrazolone treated with chromic agents.



  The chromium-containing dye obtained is a brownish-red powder which dissolves in water, 10% sodium carbonate solution or 10% sodium hydroxide solution with orange-red and concentrated sulfuric acid with a yellowish color. It dyes wool from sulfuric acid baths in uniform yellow-tinged red tones that are very lightfast and whackfast.

    <I> Example: </I> The one composed of 2.24 parts of 4-chloro-2-amino-1-phenol-6-sulfonic acid and 312 parts of 1- (4 'sulfo-) a-naphthyl-3-methyl-5-pyrazolone A dye prepared in the usual way is heated to boiling under reflux for about 20 hours in 10,000 parts of water and a chromium sulfate solution containing 84 parts of chromium oxide. The chromium compound of the dye, which has separated out with sodium chloride, is filtered off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines in roten Tönen färbenden chromhaltigen Farbstoffes, dadurch gekennzeichnet, dass man den Azo- farbstoff aus diazotierter 4-Chlor-2-amino-l- phenol -6- sulfonsäure und 1- (4'- Su,lfo-)a- naphthyl-3-methyl-5-pyrazolon mit chromab gebenden Mitteln behandelt. PATENT CLAIM: Process for the production of a chromium-containing dye which dyes in red shades, characterized in that the azo dye is obtained from diazotized 4-chloro-2-amino-1-phenol -6-sulfonic acid and 1- (4'-Su, lfo- ) a-naphthyl-3-methyl-5-pyrazolone treated with chromium donating agents. Der erhaltene chromhaltige Farbstoff stellt ein braunrotes Pulver dar, das sich in Wasser, 10%iger Sololösung oder 10%iger Natronlauge mit orangeroter und in konzen trierter Schwefelsäure mit gelblicher Farbe löst. Er färbt Wolle aus schwefelsaurem Bade in gleichmässigen gelbstichigroten Tönen, die sehr gut licht- und walkecht sind. The chromium-containing dye obtained is a brownish-red powder which dissolves in water, 10% strength solo solution or 10% strength sodium hydroxide solution with orange-red and concentrated sulfuric acid with a yellowish color. It dyes wool from sulfuric acid baths in even, yellow-tinged red tones that are very lightfast and whackfast.
