COATED METAL PLATE AND EXTERIOR BUILDING MATERIAL
PROBLEM TO BE SOLVED: To provide a coated metal plate for exterior application, which is chromate-free and yet has excellent corrosion resistance in a flat part.SOLUTION: A coated metal plate according to this invention is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.01-15% by volume of porous particles as a gloss control agent. If R (μm) is the number average particle diameter of the gloss control agent, T (μm) is the film thickness of the coating film, and σ is the standard deviation of the number-based particle size distribution of the gloss control agent, the coated metal plate satisfies the following formula: (R+2σ)/T≤0.7; R≥2.0; 9≤T≤19.
【課題】外装用の塗装金属板であって、クロメートフリーでありながら優れた平坦部耐食性を有する塗装金属板を提供する。【解決手段】本発明に係る塗装金属板は、外装用のクロメートフリーの塗装金属板であり、金属板と、前記金属板上に配置される上塗り塗膜とを有する。当該上塗り塗膜は、０．０１〜１５体積％の細孔粒子を光沢調整剤として含有する。光沢調整剤の個数平均粒径をＲ（μｍ）、上塗り塗膜の膜厚をＴ（μｍ）、光沢調整剤の個数粒度分布の標準偏差をσとしたときに、上記塗装金属板は、下記式を満足する。（Ｒ＋２σ）／Ｔ≰０．７Ｒ≧２．０９≰Ｔ≰１９【選択図】なし
