PURPOSE:To obtain the titled plastics with markedly improved weather-ability, by providing, on the surface of a plastic base at least the surface layer of which is impregnated with ultraviolet light absorber, primer layer followed by hard-coat layer. CONSTITUTION:A plastic base (of any shape formed from polycarbonate resin, acrylic resin, ABS resin, etc.) is immersed in a solution prepared by dissolving an ultraviolet light absorber (e.g., of benzophenone-, triazole-, benzoate-base) in, e.g., isopropyl alcohol. The resultant plastic base is coated with a primer (e.g., of silicone-, acrylic-base), e.g., by spraying process to provide primer layer through air-drying, followed by coating spreading process to provided hard-coat layer through air-drying, thus obtaining the objective plastics.
