Claim:
A compound of formula (I), and the addition salts thereof wherein: a ranges from 0 to 4, it being understood that when a is greater than or equal to 2, then the radicals R 1 may be identical or different, b ranges from 0 to 4, it being understood that when b is greater than or equal to 2, then the radicals R 4 may be identical or different, c is equal to 0 or 1, R 1 is chosen from a halogen atom; C 1 –C 8 aliphatic and alicyclic, saturated and unsaturated hydrocarbon-based chains, wherein at least one carbon atom is optionally replaced with at least one entity chosen from oxygen, nitrogen, silicon, and sulphur atoms and an SO 2 group; and an onium radical Z; with the proviso that the radical R 1 does not comprise a peroxide bond or diazo, nitro or nitroso radicals, R 2 comprises an onium radical Z, wherein an onium radical is a nitrogen-based quaternary radical, R 3 is chosen from an alkyl radical; an alkenyl radical; an alkynyl radical; a hydroxyl radical; a hydroxyalkyl radical; an alkoxy radical; an alkoxyalkyl radical; an alkylcarbonyl radical; a hydroxyalkoxyalkyl radical; an amino radical; a monoalkylamino radical; a dialkylamino radical; an aminoalkyl radical; an aminoalkyl radical wherein the amine is monosubstituted or disubstituted with at least one radical chosen from alkyl, acetyl and hydroxyalkyl radicals; a hydroxyl radical; a aminoalkyl radical; a carboxyl radical; a carboxyalkyl radical; a carbamoyl radical; a carbamoylalkyl radical; an alkoxycarbonyl radical; a monoalkylaminocarbonyl radical; a dialkylaminocarbonyl radical; a monoalkylaminocarbonylalkyl radical; and a dialkylaminocarbonylalkyl radical; R 4 is chosen from an alkyl radical; an alkenyl radical; an alkynyl radical; a hydroxyalkyl radical; an alkoxyalkyl radical; an alkylcarbonyl radical; a hydroxyalkoxyalkyl radical; an aminoalkyl radical; an aminoalkyl radical wherein the amine is monosubstituted or disubstituted with at least one radical chosen from alkyl, acetyl and hydroxyalkyl radicals; a hydroxyl radical; a aminoalkyl radical; a carboxyl radical; a carboxyalkyl radical; a carbamoyl radical; a carbamoylalkyl radical; an alkoxycarbonyl radical; a monoalkylaminocarbonyl radical; a dialkylaminocarbonyl radical; a monoalkylaminocarbonylalkyl radical; and a dialkylaminocarbonylalkyl radical.
