Description
Verfahren zur Herstellung eines naehehromierbaren, grünen Triphonylmethan- Azofar bstoffes. Es wurde gefunden, dass diazotiertes p-Amino-o-sulfo-tetramethyl-p-p-diamino-tri- phenylmethan mit 1-(2'-Oxy-3'-carboxy-5'- methyl) - phenyl - 3 - methyl- 5 -pyrazolon zu einem gelben Farbstoff gekuppelt werden kann, welcher sich in konzentrierter Schwe felsäure mit gelber Farbe löst,
Wolle aus saurem Bade goldgelb, nach.chromiert walk-, potting- und lichtecht rein grün färbt. Beispiel 42,5 Teile p-Amino-o-sulfo-tetram-ethyl- p-p-diamino-triphenylmethan werden diazo- tiert und zu einer so:daalkalisclh gehaltenen wässerigen Lösung von 25,0 Teilen 1-(2' Oxy-3'-oarboxy-5'-methyl)-phenyl-3-methyl- 5-pyrazolon gegeben.
Es entsteht sofort ein orangegelber Brei des Pyrazolonfarbstoffes, welcher nach dem Aussalzen filtriert, ge presst und getrocknet wird.
Process for the production of a near-chromable, green triphonylmethane-azo fiber. It has been found that diazotized p-amino-o-sulfo-tetramethyl-pp-diamino-triphenylmethane with 1- (2'-oxy-3'-carboxy-5'-methyl) - phenyl - 3 - methyl-5 -pyrazolon can be coupled to a yellow dye, which dissolves in concentrated sulfuric acid with a yellow color,
Wool from acid baths is golden yellow, after being chromed, it dyes mill-, potting- and lightfast pure green. Example 42.5 parts of p-amino-o-sulfo-tetram-ethyl-pp-diamino-triphenylmethane are diazo- tated and form an aqueous solution of 25.0 parts of 1- (2 'oxy-3'- oarboxy-5'-methyl) -phenyl-3-methyl-5-pyrazolone given.
An orange-yellow paste of the pyrazolone dye is formed immediately, which, after salting out, is filtered, pressed and dried.
