ABSTRACT:
A process for producing an easily adherable biaxially stretched polyester film, which comprises coating a primer composition consisting of (A) and aqueous dispersion of polyurethane and (B) a montan wax salt and optionally a nonionic or anionic surface-active agent on the surface of a polyester film which has not yet been stretched completely, drying the coating, completing the stretching of the coated film, and then heat-setting it thereby to form a primer coated layer on the film surface.
