Abstract:
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.
Abstract:
Provided is an additive masterbatch comprising a low-melting-point resin additive at a high concentration, which additive masterbatch can be continuously produced without strand breakage, shows excellent clumping resistance to inhibit bleeding from a pellet thereof and thus has few use restrictions for potential application.The resin additive masterbatch is characterized by comprising, with respect to 100 parts by mass of (A) a polyolefin resin: 50 to 200 parts by mass of (B) a resin additive having a melting point of not higher than 65° C.; and 10 to 20 parts by mass of (C) an inorganic layered compound.
Abstract:
A light stabilizer masterbatch contains a polypropylene-based resin (A) and a light stabilizer (B), where the light stabilizer masterbatch is composed such that the light stabilizer (B) includes a hindered amine compound (B-1) including one or two or more predetermined compounds and includes a predetermined phenol-based antioxidant (B-2), the content of the light stabilizer (B) with respect to 100 parts by mass of the polypropylene-based resin (A) is more than 10 parts by mass.

Abstract:
Provided is a resin composition having excellent weather resistance, in which occurrence of initial coloration, bleeding and blooming is suppressed. The resin composition is characterized by comprising, with respect to 100 parts by mass of (A) an olefin-based resin: 0.05 to 0.3 parts by mass of (B) a hindered amine-based light stabilizer; 0.05 to 0.3 parts by mass of (C) a benzoate compound represented by the following Formula (1); and 0.001 to 0.01 parts by mass of (D) a benzotriazole-based ultraviolet absorber represented by the following Formula (2): (wherein, R1 and R2 each independently represent a hydrogen atom, an alkyl group having 1 to 12 carbon atoms or the like; and R3 represents an alkyl group having 8 to 30 carbon atoms) (wherein, R4 and R5 each independently represent, for example, a hydrogen atom; R6 and R7 each independently represent a hydrogen atom or an alkyl group having 1 to 18 carbon atoms; R8 and R9 each independently represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms).
