Abstract

Procedure for the preparation of new azo dyes, devoid of acid water-solubilizing groups, characterized by: 1) copying the diazonium compound or a hydrazinic derivative of an azobenzothiazolyl-2-amine of the formula ** (see formula) ** Where D represents the radical of a substituted benzene or the radical of a coupling component and R means a lower alkyl group or a hydrogen atom, With a coupling component h-b; O well 2) diazoar an arylamino-benzothiazolyl-2-amine of the formula ** (see formula) ** Where Ac is an acyl radical, in particular an acetyl radical, Copying the diazonium compound with a coupling component h-b, then saponifying the acylaminic group located next to the benzene ring, diazoate the primary amine group and coupling with a coupling component h-d the resulting diazonium compound; and optionally, when the dyes obtained contain quaternizable nitrogen atoms, these dyes are treated with alkylating agents, for which the reaction components used in steps 1) and 2) must all be devoid of water-solubilizing acid substituents.
