Abstract: A clear coated metal sheet has a clear-paint film 1, which disperses an interference-coloring pigment 4 therein, formed on a base metal sheet 3 directly or through an under clear coat 6. The pigment 4 comprises transparent or translucent inorganic flakes, e.g. mica, glass, alumina or silica, coated with one or more metal oxide layers, e.g. TiO2, SiO2, ZrO2, Fe2O3, SnO2, Fe3O4, Cr2O3, ZnO or Al2O3. Incident light Lin, which enters in the clear-paint film 1, is reflected on the pigment 4 and a surface of the base metal sheet 3. A colored surface with metallic luster is observed due to interference of light on the pigment 4. Since a color tone is stable without thickness effect of the clear-paint film 1, the clear sheet is useful as decorative members.
