  Process for the preparation of a nonoazo dye. -The subject of the present additional patent is a process for the production of a monoazo dye, characterized in that 2-amino-1-phenoIdodecyl ether is diazated and coupled with 1-benzoylamino-8-oxynaphthalene-3, 6-disulfonic acid.

   The dyestuff obtained in this way dyes whale and silk from acidic and neutral baths in well-kneading, glow. blue-red tones.
