Abstract
Film comprises a base plastic film coated on one or both sides with a copolymer of 75-90 mole % vinylidene chloride, 2-16, pref. 6-10, mole % carboxylic acid ester or (meth)acrylonitrile, 0.5-5, pref. 0.5-3 mole % itaconic acid or its 1-4C alkyl ester and 3-8, pref. 4-7, mole % (meth)acrylamide of N-methylolacrylamide. A photosensitive photographic emulsion layer is coated on one or both of the copolymer layers. The intermediate copolymer layer ensures good adhesion of the emulsion layer. The adhesion is more resistant to liquid developers and alcohol than when conventional vinylidene chloride copolymers are used.
