Abstract
The invention relates to novel monobenzenic dyes including at least one cationic group Z, Z chosen from quaternized aliphatic chains, aliphatic chains including at least one quaternized saturated ring and aliphatic chains including at least one quaternized unsaturated ring, to their use as oxidation-dye precursors for the oxidation-dyeing of keratin fibers, to dye compositions containing them and to oxidation-dyeing processes using them.
