2. Description of the Related Art In the industry of manufacturing products such as automotive interior materials, there is a strong demand for a coated steel sheet having a more natural stone tone. In response to such demands, several stone-grain coated steel sheets have been developed. As such a steel sheet,
A coating material containing an inorganic powder such as 200 μm silica or alumina is applied to a steel sheet,
There is a type in which a paint containing a colored spherical resin powder having a cross-linked reinforcement of μm is applied to a steel sheet.

果、本発明を完成させた。The present inventors have conducted intensive studies to achieve the above object. As a result, metal foils of metallic pigments conventionally used are manufactured by machining such as ball mills and stamp mills. The resulting fine irregularities remain on the surface, which causes irregular reflection, and shows a certain degree of brilliancy, but it is inferred that it is inferior to the glitteriness of mica contained in natural stone. In that regard, the glass flakes produced by cooling and solidifying from a liquid were focused on being a flaky substrate having an extremely smooth surface, and as a result of further studies, the present invention was completed.
