Der Einsatz zum Färben von Keratinmateria­ lien ist nicht bekannt. Auf Polyacrylnitril werden intensive Fär­ bungen erzielt. Die Leuchtkraft der Farbstoffe ist jedoch verhält­ nismäßig gering.can be obtained with suitable benzene diazonium compounds. The main application of the dyes is the coloring of Polyacrylonitrile fibers. The use for dyeing keratin matter lien is not known. Intensive color on polyacrylonitrile exercises achieved. However, the luminosity of the dyes is behaving moderately low.

Für glänzende Haarfärbungen werden vorzugsweise Farbstoffe mit hoher Leuchtkraft verwendet.For glossy hair colors, dyes with a high color are preferred Luminosity used.

Edition, 1958) vol. XI, 2, N-connections, Vol. II / III, page 606 it is known that the alkylation of N, N'-diphenyl-N, N'-diethylethylenediamine depending on Alkylating agent leads to different products. With Methyl iodide as the alkylation agent becomes the methylation of a tertiary amine nitrogen to N-methyl-N-ethyl-N-phenyl-N-  (N'-ethyl-N'-phenylaminoethyl) ammonium iodide of the formula
