Abstract:
1. A dissymmetrical cationic diazo compound chosen from those of formula (I), (II) and (III) below, their resonance forms, acid addition salts, and solvates, and mixtures thereof, wherein in the compounds of formulae (I), (II), and (III), the formula members attached to each side of the linker L are either compositionally different or positionally different such that the compounds as a whole are dissymmetrical: wherein: the radicals R e is an integer ranging from 0 to 4; when e is less than 4, the unsubstituted carbon atom(s) of the heterocycle of the formulae (I), (II), and (III) carry a hydrogen atom; the radicals R m′ is an integer from 0 to 4; when m′ is less than 4, then the unsubstituted carbon atom(s) of the aromatic ring of the formulae (I), (II), and (III) carry a hydrogen atom; the W L is chosen from a cationic linker and a non-cationic linker; and An is chosen from at least one identical or different cosmetically acceptable anions which ensure the electroneutrality of the compounds of formulas (I), (II) and (III).
