<p>[PROBLEMS] To provide a resin composition which can be a material for producing a synthetic resin product having no default in its appearance, by the use, as a raw material, of a waste plastic material containing, as a primary component, a thermoplastic resin having a small amount of an insoluble solid foreigner incorporated therein. [MEANS FOR SOLVING PROBLEMS] A recycled resin composition prepared by incorporating a light shielding component into a ground product of a waste plastic material containing a primary amount of a thermoplastic resin and a small amount of a non-thermoplastic solid foreigner, and melting the resultant mixture by heating, wherein a sheet prepared from said recycled resin composition exhibits a lightness and a light transmittance having a relationship represented by the following formula: (A X B) <= 4000 [wherein A represents a lightness (%) of a sheet prepared from the resin composition having a thickness of 3 mm, and B represents a total light ray transmittance (%) of a sheet prepared from the resin composition having a thickness of 50 mum.</p> |
