PROBLEM TO BE SOLVED: To provide a color resin composition for the substrate of an optical recording medium which is excellent in decorating property, which can be instantly judged for its kind and use, and particularly, which is colored as suitable for an optical recording medium laminated with a UV-curing adhesive layer. SOLUTION: The resin composition for the substrate of a laminated optical recording medium consists of a thermoplastic resin (A component) and a fluorescent coloring agent (B component) and has the following properties. A planar molded product consisting of the resin composition having 0.6 mm thickness shows >=15% maximum transmittance for rays of 350 to 400 nm wavelength, <=30% minimum transmittance for rays of 400 to 650 nm wavelength and >=70% transmittance for rays at 650 nm wavelength. |
