Abstract
Process for the preparation of new azo dyes, characterized by preparing monoazo dyes of the formula ** (see formula) ** In which R means a trisulfonaphtyl radical- (2), Z means a hydrogen atom or an alkyl or alkoxy group of low molecular weight, Y X means the radical of a 4-chloro (or bromo) -2-alkoxy-1,3,5-triazine bound by means of a bridge -nh, By condensation of the respective aminomonoazo dyes with 4,6-dichloro (or dibromo) -2-alkoxy-1,3,5-triazines.
