Abstract A resinous coated metal film is produced by depositing metal on a support to form thereon a metal film and forming on the thus deposited metal film an autodeposited resinous coating. In one embodiment, the autodeposited resinous coated metal film is formed by immersing a metallic substrate in a modified autodepositing composition, that is, an autodepositing composition modified by the addition thereto of dissolved metal which is more noble than the metallic substrate. In another embodiment, a metal film is preformed on a metallic substrate, and thereafter the metallic substrate, having thereon the metal film, is contacted with an autodepositing composition. The metal film having thereon the autodeposited coating can be separated from the metallic substrate.
A process for forming a resinous coated metal film comprising contacting an iron surface with an autodepositing composition comprising resin solids, dissolved fluoride and dissolved ferric iron, and also including dissolved metal which is more noble than said iron surface, thereby forming on said iron surface a metal film of said more noble metal and on said film an autodeposited resinous coating, and removing said resinous coated metal film from said iron surface.
