PROBLEM TO BE SOLVED: To provide a method for suppressing coloration, especially, coloration due to an influence of amine derived from laminated polyurethane without impairing other physical properties such as cold resistance and volatilization resistance in a vinyl chloride resin, especially, in an automobile interior material, and to provide a vinyl chloride resin composition in which coloration is suppressed by the method, a vinyl chloride resin molding formed from the same, an automobile interior material formed from the molded material, and a plasticizer composition which is a raw material of the automobile interior material and has an effect for suppressing coloration.SOLUTION: A plasticizer composition containing an epoxy compound having at least one ester group in phthalic acid diester having a specific structure and a molecule having a specific structure is blended with a vinyl chloride resin as a plasticizer, and thereby flexibility and cold resistance are excellent, heat resistance such as volatilization resistance is excellent, and colorability, especially, amine colorability by an influence of amine is remarkably improved.SELECTED DRAWING: None
【課題】 塩化ビニル系樹脂、特に自動車内装材において耐寒性、耐揮発性等の他の物性を損なうことなく、着色、特に積層されたポリウレタンに由来するアミンの影響による着色を抑制する方法、並びに上記方法により着色の抑制された塩化ビニル系樹脂組成物、それからなる塩化ビニル系樹脂成形体、更にはその成形体からなる自動車内装材、及びその原料である着色の抑制に効果のある可塑剤組成物を提供することを目的とする。【解決手段】 特定の構造のフタル酸ジエステルと特定の構造を有する分子内に少なくとも1つのエステル基を有するエポキシ化合物を含んでなる可塑剤組成物を塩化ビニル系樹脂に可塑剤として配合することにより、柔軟性や耐寒性が良好であり、耐揮発性等の耐熱性に優れ、かつ課題であった着色性、特にアミンの影響によるアミン着色性を著しく改善することを見出し、上述課題を解決することが可能となった。【選択図】なし
