Abstract

Procedure for the preparation of water-insoluble monoazo dyes of the general formula (1) ** (See formula) ** in which D means the radical of a diazo component of the benzene, azobenzene or heterocyclic series, free of water-solubilizing groups; K means a radical of the benzene or naphthalene series, optionally containing non-aqueous-solubilizing groups, with which the substituted amino group and the azo group are joined to each other in the "para" position; R1 means a hydrogen atom or an alcohol radical with 1 to 4 carbon atoms, optionally substituted by non-aqueous-solubilizing groups; R2 and R3 signify hydrogen atoms or C 1 -C 4 alcohol groups; and n means a number from 1 to 3, characterized in that an amine of the general formula (2) is diazotized D-NH2 (2) in which D has the aforementioned meanings, and is coupled with a coupling component of the general formula (3) ** (See formula) ** in which K, R1, R2, R3 and n have the aforementioned meanings.
