  • Patent number: 9933550
    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.
