Abstract
An effective electrically insulating film on the surface of a metal object, such as a common type of electric motor core assembly, in which the surface includes an interior comer on which insulation is desired, can be formed by autodeposition with an adequate thickness in the interior corner without need for excessive thickness on other parts of the surface that are more readily covered by prior art methods of applying an insulating coating. If the autodeposition composition used includes as its primary film-forming component a copolymer of certain acrylic monomers, a very high volume resistivity can be achieved.
