<P>PROBLEM TO BE SOLVED: To provide a coated metal sheet in which peeling of a clear layer over time is remarkably suppressed while the visibility of a colored coating material layer through the clear layer is secured and which therefore is excellent weatherability. <P>SOLUTION: The coated metal sheet 1 includes a metal sheet 2, the colored coating material layer 3 formed by applying coating onto the metal sheet 2 and the clear layer 4. The clear layer 4 has visible light transmission property and is laminated on the outer surface of the colored coating material layer 3. The colored coating material layer 3 has ≤0.7% ultraviolet light transmittance in 300 nm wave length when the thickness is ≤7 μm. Even when the colored metal sheet 1 is irradiated with ultraviolet light in outdoor exposure for a long period, deterioration in the colored coating material layer 3 near the interface with the clear layer 4 is suppressed since the colored coating material layer 3 has a prescribed ultraviolet light transmissivity. <P>COPYRIGHT: (C)2011,JPO&INPIT |
