PROBLEM TO BE SOLVED: To provide a polyester resin-coated metal sheet for a container which can correspond to many characteristics necessary for a food can material. SOLUTION: The coated metal sheet has resin layers containing a polyester as the main component on both sides of a metal sheet. The resin layer to be the outer surface side of the container after the container is molded from the metal sheet is made of polyester resin layers of a multiple layer structure. The polyester resin layer forming the uppermost layer of the polyester resin layers contains a block-free isocyanate compound and an alkylene-bis-fatty acid amide. The mole number of NCO groups contained in the isocyanate compound is preferably 1.0-15.0 times of the mole number of OH groups contained in the polyester resin layer forming the uppermost layer. The alkylene-bis-fatty acid amide, in relation to the polyester resin layer forming the uppermost layer, preferably contains 1-10 mass%. COPYRIGHT: (C)2010,JPO&INPIT |
