The present invention provides a multilayer film composition wherein at least two layers of the multilayer film composition are applied via electrophoretic deposition processes. In a preferred embodiment, the first layer of the multilayer film composition is a conductive film layer applied by a cationic electrodeposition process with a second layer applied directly to the conductive first layer via an anodic electrodeposition process. Preferably, the second layer of the anodic electrocoat coating composition comprises a carbamate functional anodic resin.
