.THETA. The subject of the invention is new mono-benzenic dyes. comprising at least one cationic group Z, Z being chosen from quaternized aliphatic chains, aliphatic chains comprising at least one ring saturated quaternized, and aliphatic chains comprising at least one quaternized unsaturated cycle, their use at title of precursor of oxidation dyes for the oxidation tincture of keratin fibers, dye compositions containing them, as well as oxidation dyeing processes using them. The new dyes in question not only suitable for use as dye precursors oxidation, but in addition they make it possible to obtain dye compositions leading to dyes powerful, in a wide range of colors, and having excellent resistance properties to different treatments that fibers can undergo keratinous. |
