Precoated metal sheet and method of production of precoated metal sheet
A precoated metal sheet produced by simultaneous multilayer coating, and a process for producing the same, is provided with improved color shading prevention and adhesion. In the precoated metal plate, the centerline average roughness Ra in the coating film interface is not less than 0.3 μm, and the maximum height from the waviness center line in the interface is not more than 50% of the layer thickness. Also provided is (i) a top clear coated metal plate, which comprises a clear layer as an upper layer, has an interfacial centerline average roughness Ra of 0.3 to 0.7 μm and has excellent weathering resistance; and (ii) a precoated metal plate having excellent processability and corrosion resistance, which contains not less than 30% by mass of a rust preventive pigment.
