Abstract:
1. A dissymmetrical cationic diazo compound chosen from compounds of formula (I), their resonance forms, their acid addition salts, and their solvates: in which: the radicals R when e is equal to 2, the two radicals R e is an integer ranging from 0 to 4; when e is less than 4, the one or more unsubstituted carbon atoms of the heterocycle that result from formula (I) carry a hydrogen atom, the radicals R when m′ is greater than or equal to 2, two adjacent radicals R m′ is an integer ranging from 0 to 4; when m′ is less than 4, the one or more unsubstituted carbon atoms of the aromatic ring that result from formula (I) carry a hydrogen atom; the radicals W L is chosen from cationic linkers and non-cationic linkers; the electroneutrality of the compound of formula (I) being ensured by at least one identical or non-identical, cosmetically acceptable anion An; and the members attached to each side of the linker L in the compounds of formula (I) are either compositionally different or positionally different such that the compounds as a whole are dissymmetrical.
