A new class of salts, such as LiBF4, LiPF6, LiCIO4, CH3(C2H5)3NBF4, (C2H5)4NBF4, Li CF3SO3, Li N (CF3SO2)2, Li C (SO2CF3)3, Na SCN, Li N(CF3SO2)(C4F9SO2) and Li N (SO2CF2CF3)2, may be used in polyurethane material to impart sufficient conductivity to the conductive components in electrophotographic 100 and electro static dissipative devices. Conductivity of lithium containing polyurethane material may be further increased by including di-ethylene glycol, tri-ethylene glycol or tetra-ethylene glycol moieties in the polyol.

La présente invention concerne une nouvelle classe de sels, tels que le LiBF4, le LiPF6, le LiCIO4, le CH3(C2H5)3NBF4, le (C2H5)4NBF4, le Li CF3SO3, le Li N (CF3SO2)2, le Li C (SO2CF3)3, le Na SCN, le Li N(CF3SO2)(C4F9SO2) et le Li N (SO2CF2CF3)2, qui peuvent être utilisés dans un matériau de polyuréthane pour conférer une conductivité suffisante aux composants conducteurs dans des dispositifs dissipatifs électrophotographiques 100 et électrostatiques. La conductivité d~un matériau de polyuréthane contenant du lithium peut être en outre augmentée en ajoutant des groupes de diéthylèneglycol, de triéthylèneglycol ou de tétraéthylèneglycol au polyol.
