Polyester coated films using an aqueous polyester dispersion and photographic layer

A process for the production of a light-sensitive photographic film which comprises applying an aqueous dispersion of a synthetic polyester or copolyester derived from the condensation of one or more organic acids having at least three functional acid groups or an anhydride or a lower alkyl ester of such an acid with one or more glycols, which polyester or copolyester contains free-functional acid groups and has an acid number in the range 1 to 120 to one or both surfaces of a film of a synthetic linear polyester, drying said aqueous dispersion to a layer having a dry coat weight in the range 0.1 to 10.0 mg/dm.sup.2 and applying a light-sensitive photographic layer over one or both layers applied from the aqueous dispersion of the synthetic polyester or copolyester.
