Description

  

  Zusatzpatent zum Hauptpatent Nr. 162464.    Verfahren zur Herstellung eines in roten Tönen färbenden     ehromhaltigen        Farbstores.       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 - (2'-     M:ethyl-          4'-sulfo-)phenyl-3-methyl-5-pyrazolon    mit       ehromabgebenden    Mitteln behandelt.  



  Der erhaltene     ehro@mhaltige    Farbstoff  stellt ein braunrotes Pulver dar, das sich in  Wasser sehr leicht mit roter Farbe löst und  Wolle aus saurem Bade in gleichmässigen,  echten     gelbstiehigroten    Tönen färbt.         Beispiel:

       55 Teile des     Azofarbstoffes        aus,diazotier-          ter        4-Chlor-2-amino-l-phenol-6-sulfonsäure     und     1-(2'-Methyl-4'-sulfo-)phenyl-3-methyl-          5-pyrazolon    werden mit etwa 1000 Teilen  Wasser und 120 Teilen einer 1$ %     igen    Chrom  sulfatlösung mehrere Stunden unter Rück-         fluss    zum .Sieden erhitzt. Die durch Kochsalz  zugabe abgeschiedene Chromverbindung wird       abfiltriert    und getrocknet.



  Additional patent to the main patent no. 162464. Process for the production of an Ehrom-containing dye store which dyes 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 - sulfonic acid and 1 - (2'- M: ethyl- 4'-sulfo-) phenyl-3-methyl-5-pyrazolone treated with Ehroma-donating agents.



  The ehro @ m-containing dye obtained is a brown-red powder which dissolves very easily in water with a red color and dyes wool from an acid bath in even, genuine yellow-red shades. Example:

       55 parts of the azo dye from diazotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and 1- (2'-methyl-4'-sulfo) phenyl-3-methyl-5-pyrazolone are with about 1000 parts of water and 120 parts of a 1% strength chromium sulfate solution heated to boiling under reflux for several hours. The chromium compound deposited by adding 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-sulfons@äure und 1-(2'-Methyl-4'- sulfo-) phenyl - 3 - methyl - 5 - pyrazolon mit chromabgebenden Mitteln behandelt. PATENT CLAIM: Process for the production of a chromium-containing dye which stains in red shades, characterized in that the azo dye is obtained from diazotized 4-chloro-2-amino-1-phenol-6-sulfonic acid and 1- (2'-methyl -4'-sulfo-) phenyl - 3 - methyl - 5 - pyrazolone treated with chromium donating agents. Der erhaltene ehromhaltige Farbstoff stellt ein braunrotes Pulver dar, das sich in Wasser sehr leicht mit roter Farbe löst und Wolle aus saurem Bade in gleichmässigen, echten gelbstichigroten Tönen färbt. The dye containing Ehrom is a brown-red powder that dissolves very easily in water with a red color and dyes wool from an acid bath in even, genuine yellow-tinged red tones.
