ABSTRACT:
A photographic film that is especially useful as a motion picture print film is comprised of a support having, in order, on one side thereof an antihalation undercoat and at least one silver halide emulsion layer and having, in order, on the opposite side thereof an antistatic layer and a protective topcoat; wherein the protective topcoat is comprised of a polyurethane binder and a lubricant and the polyurethane binder has a tensile elongation to break of at least 50% and a Young's modulus measured at 2% elongation of at least 50000 lb/in.sup.2. The polyurethane binder provides a tough but flexible protective topcoat that is capable of resisting abrasion and scratching when the film is conveyed through a projector and capable of standing up to the repeated use to which motion picture print films are typically subjected.
