Zusammenfassung:A motion picture print film comprising a support having on one side thereof at least one silver halide emulsion layer and an outermost protective overcoat layer comprising a film-forming binder, and having on the opposite side thereof an outermost protective backcoat layer comprising a film-forming binder; wherein the protective overcoat and backcoat layers each comprise at least 1 mg/m of permanent matting agent having an average size of from 0.5 to 3 micrometers, the total permanent matting agent amount in the overcoat and backcoat layers combined is less than 25 mg/m , at least one of the overcoat or backcoat layers comprises soluble matting agent having an average size of from 0.5 to 3 micrometers which is removed upon photographic processing, and the total soluble matte amount in the overcoat and backcoat layers combined is from 2.5 to 30 mg/m . Print films in accordance with the invention simultaneously give excellent protection from ferrotyping, improved resistance to the generation of dirt and abrasion, and excellent image quality and soundtrack reproduction.
