Abstract (en)
An electrophotographic toner composition which comprises a colorant and a resin. The resin is an amine copolymer or terpolymer having the formula: <CHEM> wherein M1 is a monomeric unit, such as styrene methyl methacrylate, n-butyl methacrylate, isobutyl styrene; M2 is a similar monomeric unit different from M1, R1 and R2 are independently selected from hydrogen and carbon containing radicals with from 1 to 8 carbon atoms, such as hydrocarbon and substituted hydro-carbon radicals, R3 is hydrogen or a hydrocarbon group with from 1 to 8 carbon atoms, n is an integer between 50 and 100,000 and Y is an integer between 1 and 5, said copolymer or terpolymer being prepared by vinyl or addition polymerization.
