ABSTRACT:
A method for manufacturing colored metal sheet or coil at a high speed according to the principle of a two coating- one baking method, in which a primer coat is formed at a high speed by an electrodepositing coating and a final coat is formed by the painting of a finishing paint, which is polymerizable by electron beams and then the coated metal sheet or coil is subjected to an electron beaming, whereby a colored metal sheet having two coatings which are hardened by electron beams and excellent in anticorrosiveness and workability may be obtained at a high speed.
