Abstract:
1. A symmetrical cationic diazo compound of formula (I), the resonance forms, the acid addition salts and/or solvates thereof: wherein: the radicals R 2 , which may be identical or different, are chosen from: optionally substituted C hydroxyl groups, C C alkoxycarbonyl groups (RO—CO—) in which R is chosen from C alkylcarbonyloxy radicals (RCO—O—) in which R is chosen from C alkylcarbonyl radicals (R—CO—) in which R is chosen from C amino groups, amino groups substituted by one or two identical or different C alkylcarbonylamino groups (RCO—NR′—) in which the radical R is chosen from C aminocarbonyl groups ((R) ureido groups (N(R) aminosulphonyl groups ((R) alkylsulphonylamino groups (RSO optionally substituted aryl radicals; optionally substituted (C alkylsulphinyl groups (R—SO—) in which R is chosen from C alkylsulphonyl groups (R—SO nitro groups; cyano groups; halogen atoms; thio groups (HS—); and alkylthio groups (RS—) in which the radical R is chosen from optionally substituted C e is an integer ranging from 0 to 4; when e is 2, the two radicals R when e is less than 4, the unsubstituted carbon atom(s) of the heterocycle carry a hydrogen atom, the radicals R 3 , which may be identical or different, are chosen from: optionally substituted C hydroxyl groups, C C alkoxycarbonyl groups (RO—CO—) in which R is chosen from C alkylcarbonyloxy radicals (RCO—O—) in which R is chosen from C alkylcarbonyl radicals (R—CO—) in which R is chosen from C amino groups; amino groups substituted by one or two identical or different C alkylcarbonylamino groups (RCO—NR′—) in which the radical R is chosen from C aminocarbonyl groups ((R) ureido groups (N(R) aminosulphonyl groups ((R) alkylsulphonylamino groups (RSO thio groups (HS—); alkylthio groups (RS—) in which the radical R is chosen from C alkylsulphinyl groups (R—SO—) in which R is chosen from C alkylsulphonyl groups (R—SO nitro groups; cyano groups; and halogen atoms; m′ is an integer ranging from 0 to 4; when m′ is greater than or equal to 2, two adjacent radicals R when m′ is less than 4, then the unsubstituted carbon atom(s) of the aromatic ring carry a hydrogen atom; W 1 radicals, which are identical, are chosen from: hydrogen atoms, halogen atoms chosen from bromine, chlorine and fluorine, and —NR wherein: R R R R Ph is chosen from optionally substituted phenyl radicals; L is a cationic or non-cationic linker; wherein the electroneutrality of the compound of formula (I) is ensured by at least one cosmetically acceptable anion (An).
