Abstract

New basic azo dyestuffs of the formula ##STR1## where D.sup.(+) is the radical of an aromatic or heterocyclic diazo component containing a quaternary nitrogen atom, PA1 A is an aromatic radical or, together with the -(NR)-member of the formula, forms a heterocyclic radical, PA1 R is hydrogen, optionally substituted lower alkyl, aralkyl or cycloalkyl, PA1 X.sup.(-) is an anion, and PA1 Z is hydrogen or methyl, Had been found which are suitable for dyeing and forming, for example, tannin-treated cellulose fibers, silk, leather, acetate silk, acid modified polyamide or polyester fibers and for dyeing and printing and spin-dyeing of polyacrylonitrile or polyvinylidene cyanide containing fibers. The dyeings and prints obtained are generally are of high tinctorial strength and brilliant and have very good fastnesses.
