Versuchsvorschrift

On account of their easy accessibility and the neutral black shade obtainable therewith, particular interest attaches to the dyes that are derived from 1-hydroxy-2 amino-4-nitrobenzene or 1-hydroxy-2-amino-5-nitrobenzene as diazo components, and from 1-hydroxy-7-aminonaphthalene-3-sulphonic acid or 1-hydroxy-6-aminonaphthalene-3-sulphonic acid as coupling component.
