The present invention provides a recycled plastic article obtained by modifying the surface of a molded article formed from a collected plastic with a colored film which comprises an acrylic resin containing an ultraviolet absorber and has a thickness of from 50 &#x3bc;m to 600 &#x3bc;m. Plastics which are used widely in domestic electric products, automobile parts, industrial parts and the like and have various tones are modified with an acrylic resin film so colored to an extent as to provide color shielding of the ground collected resin, to collect the plastics and produce an article without being influenced by the color of the original materials.
