Abstract
A method of providing a composite coated steel sheet is provided herein by dipping a steel sheet into a suspension solution consisting of a water-soluble and/or water-dispersible organic polymer resin, a water-dispersible sol of a metal compound and an infusible powder of a water-insoluble polymer resin, removing the coated steel sheet from the suspension and curing the coated composite by heat treatment. In certain cases, a metal powder, an alloy powder of said metal and a powder of a difficultly water-soluble or water-insoluble compound of said metal may be used in the suspension solution.
