摘要

Metu00c1lica pre-filled plate coated and method of produu00c7u00e7o plate metu00c1lica power coated. The present invention relates to a metal plate pre coated which is improved in the prevention of shading in color and in the accession and is produced by coating simultu00e3neo multiple layers.In the metal plate pre coated with the roughness average RA in the central line in terface of film coating is not less than 0,3 109 m, and the maximum height of the central line of the ripple on the interface is not more than 50% of the thickness of the layer.It is also provided with a metallic plate coated with the top, of course, which includes a clear layer as an upper layer has a roughness average RA in the central line interfacial of 0.3 to 0.7 109 m and has an excellent resistance to weather, a metal plate pre coated with an excellent Processing capacity and corrosion resistance.Containing not less than 30% by mass in the middle of a pigment to prevent the rust so that the average content of preventing rust from the upper layer is smaller than the average content of prevention against the rust of the lower layer, the concentration gradient is reduced by fo RMA the position around the interface of the upper layer and the lower layer is increased.And the roughness Ra at the interface of bottom layer and top layer is 0.3 to 0.7 109 m, and a process for pro - tions of the same.
