A particle transfer film (10) has a substrate (12) having coated thereon an exterior layer (14) of polyurethane. The polyurethane is copolymerized with a charge control agent of the formula where R represents: R represents sulfonate, oxyphenylene sulfonate, oxycyclohexylene sulfonate or p-toluenesulfonamidosulfonyl; x and y are integers which together are of sufficient value to achieve an R molecular weight of 300 to 30,000; and M represents hydrogen, an alkali metal, ammonium or P<+>(C6H5)3CH3. The charge control agent is nonleachable from the polyurethane and is present in an amount sufficient to impart a selected amount of electric charge resistivity to the polyurethane.
