Abstract

Conducting materials are provided with two coatings, the surface being covered first with an organic coating based on silicic acid and/or metal phosphate over which is applied by electrophoresis an organic coating of a material which is either anion active or cation active. For coating metals and metal surfaces which are made conducting by applying an electrodeposit, or a metal powder, or graphite.
