An orientated polyester film coated on at least one surface with a coating that improves its adhesion to water-based coatings is disclosed. The coating contains at least one sulfopolyester; at least one tetrablock copolymer resin; and at least one polymer selected from the group consisting of polyacrylic acids, acrylamide/acrylic acid copolymers, salts of the polyacrylic acids, and salts of the acrylamide/acrylic acid copolymers. Other ingredients, such as particulate materials and surfactants, may be present in the coating. The coating is preferably applied at the interdraw stage. |
