Abstract: Provided are: a stabilizer composition that can not only impart excellent thermal stability, coloration resistance, thermal coloration resistance, and the like to a vinyl chloride resin, but also impart excellent transparency to a vinyl chloride resin when used in an application where transparency is required; a vinyl chloride resin composition containing the same; and a molded body thereof. The stabilizer composition contains 5 to 2,500 parts by mass of a component (B) with respect to 100 parts by mass of a component (A). The component (A) is at least one organic acid zinc salt, and the component (B) is at least one epoxy compound having a glycidyl ether group and/or a glycidyl ester group.

Abstract: Provided are: a thermal stabilizer composition which does not generate an odor of a phosphorus-based antioxidant; and a synthetic resin composition comprising the same. The thermal stabilizer composition comprises: 100 parts by mass of a phosphorus-based antioxidant having a phosphite structure; and 0.001 to 10 parts by mass of a phenolic antioxidant having a substructure represented by the following Formula (1): (wherein, R1, R2, R3 and R4 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; a represents an integer of 0 to 2; and, when a is 2, plural R3s are optionally the same or different).

Abstract: Disclosed is a vinyl chloride-based resin composition having excellent weather resistance, coloration resistance, and thermal stability as well as excellent transparency, and a molded article using this vinyl chloride-based resin composition. Specifically, the vinyl chloride-based resin composition contains a vinyl chloride-based resin in an amount of 100 parts by mass, an organic acid zinc salt as a component (A) in an amount of 0.01 to 10.0 parts by mass, a β-diketone compound as a component (B) in an amount of 0.01 to 10.0 parts by mass, and one or more triazine-based compounds as a component (C) represented by Formula (1) in an amount of 0.01 to 20.0 parts by mass. (In Formula (1), R1 to R3 represent a linear or branched alkyl group having 1 to 12 carbon atoms or the like, and R4 to R6 represent an alkyl group having 1 to 8 carbon atoms or the like.)
