Patent ID: 7311737

Claim:
A secondary para-phenylenediamine compound chosen from compounds of formula (I), and the addition salts thereof: wherein: X is a fluorine atom; R is chosen from linear and branched C 1 –C 10 alkylene radicals, which are unsubstituted or substituted with at least one entity chosen from halogen atoms, and C 1 –C 15 alkoxy, aryl, amino, mono(C 1 –C 15 )alkylamino, di(C 1 –C 15 )alkylamino, (C 1 –C 15 )alkylcarbonyl, carboxyl, amido, (C 1 –C 15 )alkoxycarbonyl, mono(C 1 –C 15 )alkylaminocarbonyl, and di(C 1 –C 15 )alkylaminocarbonyl radicals, wherein the alkylene radicals are optionally interrupted with at least one entity chosen from carbonyl functional groups and hetero atoms chosen from oxygen and nitrogen; R′ is chosen from a hydrogen atom, and C 1 –C 15 alkyl, C 1 –C 15 alkoxy, C 1 –C 15 hydroxyalkoxy, (C 1 –C 15 )alkoxy(C 1 –C 15 )alkyl, C 1 –C 15 monohydroxyalkyl, and C 1 –C 15 polyhydroxyalkyl radicals; n is an integer ranging from 1 to 4; with the proviso that the compounds of formula (I) are not chosen from N-(3,3,3-trifluoropropyl)benzene-1,4-diamine, N-(4,4,4-trifluorobutyl)benzene-1,4-diamine, N-(5,5,5-trifluoroamyl)benzene-1,4-diamine, N-(6,6,6-trifluorohexyl)benzene-1,4-diamine, N-(2,2,2-trifluoroethyl)benzene-1,4-diamine, and N-(2,2,2-trifluoroethyl)-2-methoxybenzene-1,4-diamine.
