    摘要： 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.

    摘要： A process for the dyeing and printing of leather and various textile material with developing dyestuffs is described wherein diazo salts and specific 6-membered, heterocyclic coupling components having one ring nitrogen atom especially of the pyridone and pyridine types are applied, the coupling process being independent of the pH-value, i.e. it can be performed with a range of ca. pH 2 to 12, preferably at room temperature so that this is possible not only in alkaline but also in neutral or acid medium, depending on the substrate, and in that it is possible with it to produce with only one of the coupling components by means of variation of diazo salts the whole color range from light yellow to black.
