PURPOSE:To obtain a plastic sheet with improved designing properties by dispersing two or more kinds of titanium-coated mica each with a different thickness of a titanium dioxide-coating layer in a transparent plastic in a titanium-coated mica having a layer wherein the surface of a fine and thin piece-like mica is coated with titanium dioxide. CONSTITUTION:A transparent plastic 2 is for example, polyvinyl chloride, olefins such as polypropylene and polyethylene, polyester, polycarbonate, polyacrylonitrile, acrylic resin such as polymethyl methacrylate, transparent resins such as polystyrene and a titanium-coated mica is dispersed by using this resin as a vehicle. In the titanium-coated mica 1, a light reflecting at the boundary between the vehicle or a low valence oxide of titanium and titanium dioxide a light reflecting at the boundary between titanium dioxide and mica interfere each other to generate a shade. |
