<p>PROBLEM TO BE SOLVED: To provide a ray-reflective resin composition and a ray-reflective molded article, in which degradation in physical properties or yellow discoloration caused by degradation of a resin can be decreased by coating a surface of titanium dioxide with an intramolecular proton-transfer compound to suppress photocatalytic activity of the titanium dioxide, and further, a bleed-out phenomenon can be suppressed compared to a composition with a normal UV absorbent compounded therein, and thereby contamination of a molded article with time can be prevented and long-term weather resistance can be obtained.SOLUTION: The ray-reflective resin composition comprises titanium dioxide (A) and a thermoplastic resin (B). The titanium dioxide (A) has a first coating layer formed of a metal oxide containing aluminum oxide and a second coating layer formed of an intramolecular proton-transfer compound.</p> |
