ABSTRACT:
An anionic surfactant can be used for the preparation of aqueous dispersions of specific composition with a high degree of fineness of the particle sizes of primary aromatic amines free from carboxylic acid or sulfonic acid groups. Besides said aromatic amine and said anionic surfactant these aqueous dispersion contain as a dispersing agent a water-soluble condensation product containing one or several radicals of oxalkylated, hydroxy and/or carboxy group-containing aromatic compounds, which radicals are linked with one another by methylene bridges either directly or via radicals of aromatic compounds. The dispersions may further contain a polyhydric alcohol and optionally a high molecular weight polyglycol. The dispersions have a good viscosity behavior, a good stability in storage and are stable at temperatures of about -15.degree. to +50.degree. C. They can be readily and rapidly diazotized and yield residue-free diazonium salt solutions with low tendency to foam formation. The dispersion and the diazonium salt solutions produced therefrom can be readily used for the production of water-insoluble azo dyes on the fiber, for example in ice-color technique.
