COATED METAL SHEET, METHOD FOR MANUFACTURING SAME, AND EXTERIOR BUILDING MATERIAL
Provided is a coated metal sheet for exterior use, having a metal sheet, and a top coat film situated on the metal sheet. The top coat film contains 0.2-15 volume percent of a gloss control agent composed of porous particles and a delustering agent composed of primary particles. The coated metal sheet satisfies the following expressions in which, in the number-size distribution of the gloss control agent and the delustering agent, R is the number-average particle diameter (µm) of the gloss control agent, D1 97.5 and D2 97.5 are 97.5% particle diameter values (µm) of the gloss control agent and the delustering agent, Ru is the upper limit particle diameter (µm) of the gloss control agent, and T is the film thickness (µm) of the top coat film. D 1 97.5 / T ¤ 0.7 Ru ¤ 1.2 T R ¥ 1.0 2.0 ¤ D 2 97.5 / T ¤ 7.0 13 ¤ T ¤ 20.
