  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass ein neuer     Azo-          farbstoff    erhalten wird, wenn man 1     Mol.          diazotierte        2-Amino-l-oxybenzol-4-sulfosäure     auf 2     Mol.        ss-Naphthylamin    einwirken lässt  und die so erhaltene Doppelverbindung, be  stehend aus dem     Azofarbstoff    und     ss-Naph-          thylamin,    mit verseifend wirkenden Mitteln  behandelt.

   Der so erhaltene Farbstoff bildet  ein braunrotes Pulver, löst sich mit oranger  Farbe in Wasser, färbt Wolle aus saurem

  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if 1 mol of diazotized 2-amino-1-oxybenzene-4-sulfonic acid is allowed to act on 2 mol of β-naphthylamine and the double compound thus obtained, consisting of the azo dye and ss-naphthylamine, treated with saponifying agents.

   The dye thus obtained forms a brown-red powder, dissolves in water with an orange color, dyes wool from acidic
