Abstract: Photographic film bases and sensitized photographic films are produced by coating a supporting film, especially a linear polyester film such as a biaxially oriented and heat-set film of polyethylene terephthalate, with a subbing composition comprising a polymer of a vinyl halogenoester, such as vinyl mono-, di-, or trichloroacetate, which is then subjected to a surface modifying, e.g. corona discharge, treatment. Light-sensitive photographic emulsions adhere directly to the treated subbing layer without the need for an intermediate gelatin subbing layer. The vinyl halogenoester subbing polymer may be a copolymer formed with a softening temperature-lowering comonomer such as an alkyl acrylate, alkyl methacrylate, polyalkylene oxide itaconate or maleate, vinyl alkyl ether, vinyl ester, alkene, alkadiene or alkyl styrene, a suitable copolymer being 78/15/7 mole % vinyl monochloroacetate/ethyl acrylate/acrylamide.
