Process for the preparation of yellow wool dyes.
Azo dyes made from pyrazolones and their derivatives have already been described several times in the literature. Draw the colorations obtained with these dyes

It has now been found that the action of the diazo compounds of aminoarylsulfonamides, in which the sulfur of the sulfonamide radical with a carbon atom of the benzene or benzene group containing the amino group. Naphtaliurings is connected, and their derivatives substituted in the sulfonamide group on pyrazotones and their derivatives receive dyes which, in addition to the good properties mentioned, also have great properties

27 # 8 kg of o-anisidine-p-sulfonanilide (which can be obtained, for example, by converting the chloride of the o-nitransiol-p-sulfonic acid into the anilide and reducing it) are diaotized in the usual way and the diazo solution becomes a with excess soda

In an acidic bath it colors woUe in lively yellow tones, which are in the fulling. distinguished by a authenticity not previously achieved with direct dyeings.
If in the example the o-anisidine-p-sulfonanilide is replaced by other aminoarylsutfo-

zolonecarboxylic acids, sulfoarylpyrazolonecarboxylic acids. this gives dyes with the same good fastness properties.
To prepare the dyes from pyrazolone sulfonic acids, one can also proceed in such a way that the diazo compounds mentioned are coupled with unsulfated pyrazolones and then sulfated.
