COATED STEEL SHEET AND EXTERIOR BUILDING MATERIAL
PROBLEM TO BE SOLVED: To provide a coated steel sheet excellent in both corrosion resistance and scratch resistance.SOLUTION: A coated steel sheet comprises: a steel sheet; a primer coating film which is arranged on the steel sheet and comprises an anti-corrosive pigment and an aggregate composed of primary particles; and a top coating film which is arranged on the primer coating film. The anti-corrosive pigment comprises one or more compound(s) selected from the group consisting of a bivalent tin salt, a trivalent vanadium salt, a tetravalent vanadium salt, a tetravalent molybdenum salt, an oxycarboxylic acid salt, an ascorbic acid, a phosphorous acid salt and a hypophosphorous acid salt.
【課題】耐食性および耐傷付き性の両方に優れる塗装鋼板を提供すること。【解決手段】塗装鋼板は、鋼板と、前記鋼板の上に配置された、防錆顔料と一次粒子からなる骨材とを含む下塗り塗膜と、前記下塗り塗膜の上に配置された上塗り塗膜と、を有する。前記防錆顔料は、２価のスズ塩、３価のバナジウム塩、４価のバナジウム塩、４価のモリブデン塩、オキシカルボン酸塩、アスコルビン酸、亜リン酸塩および次亜リン酸塩からなる群から選択される１種または２種以上の化合物である。【選択図】なし
