Abstract
Process for the preparation of azo dyes, characterized in that a diazotized amine of the benzene series is coupled to a monoamine of the benzene series which couples in para position with respect to the amino group, in which amino group a hydrogen atom is substituted by a cyanoalkyl radical and the other hydrogen atom by an optionally substituted alkyl, and having an aliphatic acylamino group in the meta position with respect to this amino group, for which the components are free of acid groups of hydro-solvent power.
