ABSTRACT:
A method for the production of a metal sheet covered with polyester resin film which comprises laminating a polyester resin film which is preferably crystalline and oriented onto a metal sheet having a lower layer of metallic chromium and an upper layer of hydrated chromium oxide, which sheet has been heated to a temperature above the melting point of polyester resin film and then immediately quenching. This metal sheet covered with polyester resin film is excellent in corrosion resistance and formability.
