Abstract

Procedure for the preparation of azo compounds devoid of acidic hydrosolubilizing groups, of the general formula **(See formula)** in which d is a radical of a diazo component, A is a phenyl radical (possibly substituted), next to which the azo bridge and the tertiary amine group are in position for each other; A is a radical (linked via an amino group) of the formula -CO- (CH2) nX-aryl (where n = 1, 2 or 3, but preferably 1, and X is an oxygen or sulfur atom or an amine group); r1 is an alkyl group, unsubstituted or substituted; and r2 when X is a sulfur atom or an amine group, represents an unsubstituted or substituted alkyl group and, when X is an oxygen atom, represents a substituted alkyl group, characterized by: O well a) coupling diazonic compounds of diazo components that do not simultaneously contain nitro groups, alkylsulfonyl groups and cyanogenic groups, with amines of the formula **(See formula)** in which Ac is a radical (linked via an amino group) of the formula -CO- (CH2) nX-aryl (where n = 1, 2 or 3 and X is an oxygen or sulfur atom or a group) -nH - and the hydrogen atom and the tertiary amine group are in position for each other; O well b) condensing monoazo dyes of the formula **(See formula)** in which Ac'means a chloroalkylcarbonylaminic group primary or secondary arylamines, phenols or thiophenols; and eventually c) quaternize the dyes obtained, when they contain quaternizable nitrogen atoms.
