摘要:
[PROBLEMS] To provide a precoated metal sheet allowing to skip postcoating after press working that realizes high whiteness degree and excels in bright reflectivity. [MEANS FOR SOLVING PROBLEMS] A white precoated metal sheet of 80 or higher postcoating whiteness degree in terms of L-value of Hunter Lab color system, comprising a metal sheet provided with two or more coating layers, wherein when the superior layer coating refers to the coating constituting the outermost surface layer and the inferior layer coating refers to the coating interposed between the superior layer coating and the metal sheet, the content of white pigment in the inferior layer coating is in the range of 40 to 60 mass % while the content of white pigment in the superior layer coating is in the range of 5 to 25 mass % so as to excel in bright reflectivity.
