<p>A resin coated steel sheet which is high in corrosion resistance and workability, can be enhanced in workability, corrosion resistance and organic resin adhesiveness by forming a resin coat on the surface of a colored layer and can prevent the exposure of a base metal due to damage to a steel sheet surface at press working. The resin coated steel sheet is produced by subjecting at least one surface of a steel sheet to electrogalvanization containing at least one of cobalt, nickel and molybdenum, by subjecting the galvanized steel sheet to either anodic electrolysis or cathodic electrolysis in an acid aqueous solution, or dipping in an aqueous solution containing nitric acid ion, by coloring the surface of the galvanized steel sheet and by forming a resin coat on the surface. A cartridge cap and a cartridge barrel produced by using this resin coated steel sheet.</p> |
