Object: The present disclosure provides a film having a low gloss appearance and excellent scratch resistance, and a surface coating composition that can be used in the production of such a film. Resolution Means: The film of one embodiment of the present disclosure includes a scratch resistant surface layer containing a binder containing a urethane resin, urethane resin beads having an average particle diameter of 3 μm to 30 μm, hard particles having an average particle diameter of 5 μm to 45 μm; and nanosilica particles. The surface layer contains the hard particles in an amount of 30 parts by mass to 500 parts by mass per 100 parts by mass of the binder. The gloss of the surface layer is approximately 5.5 GU or less at 60 degrees.
