A film receptive to a variety of different classes or kinds of inks, such as water based inks, solvent based inks and UV cured inks is disclosed. The film includes a water dispersible polymer having a polar component or a water dispersible polymer and a polar polymer, such as a polymer having an ionic component to increase the receptivity of the coating to water-based inks. A surfactant, such as an alkyaryl sulfonate, to prevent agglomeration of the polymer before it is formed into film may also be included. The preferred water-dispersible polymer is a core/shell latex polymer. The preferred polar polymer is chemically compatible with latex polymers and is sufficiently ionic or polar to improve the printability onto the film of water-based inks. The surfactant, which may be in the latex as manufactured or may be added separately, and preferably has a molecular structure that includes at least one hydrophobic moiety and at least one anionic group such as sulfates, sulfonates and the like.
