PRECOATED METAL PLATE, AND EXTERIOR BUILDING MATERIAL
PROBLEM TO BE SOLVED: To provide a precoated metal plate which has gloss-adjusted desired design properties and excellent flat part corrosion resistance, which is equal to or higher than that of another precoated metal plate containing a chromate rustproof treated metal plate, even if it is a chromate-free precoated metal plate, and to provide an exterior building material.SOLUTION: The precoated metal plate is used as exterior materials and has a metal plate and a final coating film to be disposed on the metal plate. The final coating film contains a porous particle of 0.01-15 vol.% as a gloss adjusting agent. The precoated metal plate satisfies the inequality: D/T≤0.7Ru≤1.2TR≥1.03≤T≤20 (in which R is the number-average particle diameter (μm) of the gloss adjusting agent, Dis the 97.5% particle diameter (μm) thereof, Ru is the upper limit particle diameter (μm) thereof, and T is the thickness (μm) of the final coating film) in a number-based particle diameter distribution of the gloss adjusting agent.
【課題】光沢が調整された所期の意匠性を有するとともに、クロメートフリーであっても、クロメート防錆処理された金属板を含む塗装金属板と同等以上の優れた平坦部耐食性を有する塗装金属板および外装建材を提供する。【解決手段】本発明に係る塗装金属板は、外装用の塗装金属板であり、金属板と、上記金属板上に配置される上塗り塗膜とを有し、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し、上記塗装金属板は、下記式を満足する。光沢調整剤の個数粒度分布における、Ｒは個数平均粒径（μｍ）、Ｄ９７．５は９７．５％粒子径（μｍ）、Ｒｕは上限粒径（μｍ）であり、Ｔは上塗り塗膜の膜厚（μｍ）である。Ｄ９７．５／Ｔ≦０．７Ｒｕ≦１．２ＴＲ≧１．０３≦Ｔ≦２０【選択図】なし
