Abstract

The invention relates to the use of fused polycyclic compounds having at least one cationic group Z, Z being chosen from quaternized aliphatic chains, aliphatic chains having at least one quaternized saturated ring and aliphatic chains having at least one quaternized unsaturated ring, as direct dyes in compositions intended for dyeing keratin substances and, in particular, compositions intended for dyeing human keratin fibers, especially the hair, and cosmetic compositions intended for making up the skin, the nails and the lips, to the dye compositions or make-up compositions containing them and to the direct dyeing process using them.
