The present invention provides a coated polymer film having an essentially streak-free coated surface that resists the formation of fog. The film includes a self-supporting polymer film layer, and an anti-fog coating on the film layer. The anti-fog coating, which can also be applied to alternate substrates, consisting essentially of a copolyester binder and an anionic surfactant, wherein the surfactant contains less than about 0.5 weight percent of a fluorosurfactant. A slip agent can also be included in the anti-fog coating.

Anti-fog coating and coated film

A coated, oriented plastic film material is provided wherein the coating is applied in an aqueous medium comprising a water dispersible copolyester consisting essentially of the condensation product of components A, B, C and D or their polyester forming equivalents as follows:
