Abstract:
Disclosed is a coated metallic material having a high total light reflectance and excellent moldability. Also disclosed is a method for producing the coated metallic material. Further disclosed is a molded coated metallic article. The coated metallic material is characterized by comprising a coating layer having at least three layers composed of a primer layer, an intercoating layer and a top layer, wherein the intercoating layer contains rutile-type titanium oxide in an amount of 35 to 70% in terms of a solid material concentration by volume and also contains a polyester resin (A) having a number average molecular weight of 19000 to 28000 as a binder resin component, and wherein the polyester resin (A) is contained in the binder at a concentration of 20 mass % or more. In the coated metallic material, an interface between the intercoating layer and the top layer has a center-line average roughness (Ra) of 0.8 μm or more, so that the adhesion between the intercoating layer and the top layer can be further improved and the diffusion reflectance can also be further improved.
