ADDITIVE COMPOSITION AND THERMOPLASTIC POLYMER COMPOSITION COMPRISING THE SAME

PROBLEM TO BE SOLVED: To provide a clarifying agent composition for improving aesthetic quality of a thermoplastic polymer.SOLUTION: There is provided the additive composition that is composed of: a clarifying agent composition to be added to a thermoplastic polymer, such as tris amide, a monocarboxylate compound, an acetal compound which is substituted/unsubstituted bis(phenyl)-1,3,5,7-tetraoxadecalin; and a coloring agent, the coloring agent being present in an amount satisfying the following formula. In the formula, the Δa* value and the Δb* value represent difference of presence or absence of the coloring agent calculated from a* value and b* value of 1.27 mm plaque generated from the thermoplastic polymer composition.SELECTED DRAWING: Figure 1 【課題】熱可塑性ポリマーの審美的品質を改善する透明化剤組成物の提供。【解決手段】熱可塑性ポリマーに添加するトリスアミド、モノカルボキラート化合物、置換／非置換のビス（フェニル）−１，３，５，７−テトラオキサデカリンであるアセタール化合物等の透明化剤及び着色剤から成る添加剤組成物であって、次式を満足する量で着色剤が存在する添加剤組成物。（Δａ*値及びΔｂ*値は、該熱可塑性ポリマー組成物から生成した１．２７ｍｍプラークのａ*値及びｂ*値から計算される着色剤存在有無の差を示す）【選択図】図１
