COATED METAL PLATE, SHUTTER SLAT AND SHUTTER
To provide a coated metal plate which can achieve moldability and scratch resistance, and can suppress lowering of scratch resistance and corrosion resistance for a long period of time.SOLUTION: A coated metal plate has a metal plate, a first surface layer coated film which is arranged on one surface and is composed of a cured product of a first curable resin composition, and a second surface layer coated film which is arranged on the other surface and is composed of a cured product of a second curable resin composition. The first curable resin composition and the second curable resin composition each contain a curable polyester resin, a curing agent, 2-6 mass% of fluorine resin particles (to solid content), and 0.2-1.2 mass% of polyethylene particles A modified with a fluorine resin (to solid content). The curable polyester resin of the first curable resin composition has a weight average molecular weight higher than that of the curable polyester resin of the second curable resin composition. The first curable resin composition does not substantially contain polyethylene particles B that are not modified with the fluorine resin.SELECTED DRAWING: Figure 1
【課題】成形加工性と耐傷付き性とを高度に両立することができ、かつ長期間にわたり耐傷付き性および耐食性の低下を抑制できる塗装金属板を提供する。【解決手段】塗装金属板は、金属板と、その一方の面に配置された第１硬化性樹脂組成物の硬化物からなる第１表層塗膜と、他方の面に配置された第２硬化性樹脂組成物の硬化物からなる第２表層塗膜とを有する。第１硬化性樹脂組成物および第２硬化性樹脂組成物は、それぞれ、硬化性ポリエステル樹脂と、硬化剤と、（固形分に対して）２〜６質量％のフッ素樹脂粒子と、（固形分に対して）０．２〜１．２質量％のフッ素樹脂で変性されたポリエチレン粒子Ａとを含む。第１硬化性樹脂組成物の硬化性ポリエステル樹脂は、第２硬化性樹脂組成物の硬化性ポリエステル樹脂よりも重量平均分子量が高い。また、第１硬化性樹脂組成物は、フッ素樹脂で変性されていないポリエチレン粒子Ｂを実質的に含まない。【選択図】図１
