A base film including a substrate, an adhesion layer, a conductive layer, and a magnetic layer is provided. The adhesion layer preferably includes a sulfonated polyester/vinyl addition polymer, wherein the adhesion layer is disposed between the substrate and the conductive layer and improves adhesion between these layers, even under wet conditions. An adhesion layer is particularly useful in photographic elements and is at least located on a surface of the substrate that is opposite a silver halide emulsion layer, although emulsion receptivity can be enhanced by including an adhesion layer on the emulsion-side of the substrate.
