PURPOSE:To obtain the subject resin coated material excellent in weatherability by providing a coating resin layer containing a deterioration inhibitor whose concn. becoming higher toward the interior thereof from the surface thereof. CONSTITUTION:A base material is generally a steel material but the material quality thereof is not limited to steel and other metal materials such as aluminum, a stone material, wood or ceramic can be used. The resin of a coating resin layer is not also limited and various resins used as coating resins heretofore such as polyolefins, for example, polyethylene or polypropylene, polystyrene, polyvinyl chloride or the like can be used. The thickness of the coating layer is appropriately selected corresponding to the objective degree of anticorrosion but set to 0.5-5mm, especially pref., about l-3mm in the case of heavy anticorrosion. As a deterioration inhibitor to be added, a known compound such as a phenol derivative, an aromatic amine derivative, a sulfur compound or a phosphorus compound is designated. The mol.wt. of the deterioration inhibitor is pref. 100-2000, especially pref. 200-1000. |
