The present invention relates to new N-substituted anilines which correspond to the general formula: ##STR1## in which R.sub.1 represents an alkyl radical or substituted alkyl radical, R.sub.2 represents a hydrogen atom, an alkyl radical or substituted alkyl radical, R.sub.3 represents a cyano, carbamoyl, carboxy or carbalkoxy radical and R.sub.4 represents a hydrogen or halogen atom or an alkyl or alkoxy radical. These compounds are valuable intermediates for the preparation of coloring materials, especially as coupling compounds for the synthesis of azo dyes.

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.
