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, A is an aromatic radical or, together with the -(NR)-member of the formula, forms a heterocyclic radical, R is hydrogen, optionally substituted lower alkyl, aralkyl or cycloalkyl, X.sup.(-) is an anion, and 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.
A basic azo dyestuff which is free from sulfonic acid groups and has the formula ##STR346## wherein Y, together with ##STR347## is thiazolyl, benzothiazolyl, pyrazolyl, indazolyl, triazolyl, guanazolyl, quinolinyl or pyridinyl,
A basic azo dyestuff which is free from sulfonic acid groups and has the formula ##STR348## where Alk is methyl or ethyl,
