摘要：
The subject of the invention is cationic monobenzene nitrophenylenediamines having at least one cationic charge delocalized over an unsaturated 5-membered polynitrogenous heterocycle, to their use as direct dye in dyeing compositions for keratinous substances, in particular for human keratinous fibers, such as the hair, to the dyeing compositions comprising them and to the dyeing processes employing these compositions.
