THERMOPLASTIC RESIN COMPOSITION FOR LIGHT-REFLECTING BODY, MOLDED ARTICLE FOR LIGHT-REFLECTING BODY AND LIGHT-REFLECTING BODY

摘要

PPROBLEM TO BE SOLVED: To provide a light-reflecting body which is obtained by directly forming a light-reflecting metal layer on a molded article formed from a thermoplastic resin composition, excels in moldability (surface smoothness, releasability, and molding shrinkage), has good heat resistance, hardly causes a problem (an orange peel surface defect, and whitening) in the light-reflecting metal layer under an elevated temperature environment, and excels in external appearance with a clean-cut feeling. PSOLUTION: The light-reflecting body is obtained by directly forming a light-reflecting metal layer on a molded article for the light-reflecting body having reflectance of the molded article surface at 420-700 nm of ≥65% and a linear shrinkage factor of ≤1.6% which is obtained by using a thermoplastic resin composition for the light-reflecting body comprising (A) 100 pts.mass thermoplastic resin and (B) 2-45 pts.mass inorganic filler having a refractive index α of 1.61≤α≤2.5 and an average particle diameter of ≤3 μm.
