<p><P>PROBLEM TO BE SOLVED: To provide a polylactic acid resin-coated metal sheet for containers which is superior in hydrolysis resistance in a retort processing environment and satisfies many characteristics necessary for food can material. <P>SOLUTION: The resin-coated metal sheet for containers has a resin layer of a two-layer structure on at least one side. The resin layer of the two-layer structure meets the following (A) and (B), (A) in which a resin layer to be an upper layer contains a polyester having an amount of deposit of 0.1-5.0 g/m<SP>2</SP>as a main component and an isocyanate compound, and the mole number of a NCO group contained in the isocyanate compound is 5.0-20.0 times of the mole number of OH group contained in the polyester and (B) in which a resin layer to be a lower layer contains polylactic acid having a residual degree of orientation of 5-30% as a main component, and the polylactic acid contains 0.01-10 mass% of a polycarbodiimide compound. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
