More Information
Summary:A polyolefin-based resin composition of the present invention contains a polyolefin-based resin (A) and a light stabilizer (B), in which the light stabilizer (B) includes a predetermined hindered amine compound (B-1) and a predetermined phenol-based antioxidant (B-2), where the polyolefin-based resin composition is composed such that a value of the brightness increase ratio [L* (2,040 h) - L* (0 h) ] /L* (0 h) before and after the weather resistance test is -0.05 or more and less than 0.1.
