Abstract
The invention relates to new cationic azo dyestuffs which correspond to the general formula: ##STR1## in which R.sub.1 represents an alkyl radical or a substituted alkyl radical, R.sub.2 represents a hydrogen atom, an alkyl radical or a substituted alkyl radical, R.sub.3 represents a cyano, carbamoyl or carbalkoxy radical, R.sub.4 represents a hydrogen or halogen atom or an alkyl or alkoxy radical, D.sup..sym. represents a cycloammonium radical and A.sup..crclbar. represents an anion. These dyestuffs are very suitable for dyeing and printing textile materials based on polymers or copolymers of unsaturated nitriles or on acid-modified polyesters or polyamides, in shades very fast to light and wet treatments.
