摘要:
The present invention is a motion picture film including a support having on one side thereof an antihalation undercoat and at least one silver halide emulsion layer. The motion picture film has on the opposite side thereof an antistatic layer and a protective overcoat. The protective overcoat includes a layer of a polyurethane binder having a tensile elongation to break of at least 50% and a Young's modulus measured at a 2% elongation of at least 50000 lb/in.sup.2, and a topcoat farthest from said support. The topcoat is an interpolymer having repeating units of A and B wherein A is a fluorine containing acrylate or methacrylate monomer and B is an ethylenically unsaturated monomer containing hydratable groups.
