An object of the present invention is to provide a resin composition which is increased in heat resistance (high crystallinity) and transparency without impairing rigidity which a thermoplastic resin inherently has and a molded article containing the resin composition. A thermoplastic resin composition relating to the present invention includes a thermoplastic resin (A) and a crystal nucleating agent (B) composed of tris (amino acid ester) amides of trimesic acid. The crystal nucleating agent (B) is preferably tris(valine ester)amides of trimesic acid or tris(leucine ester)amides of trimesic acid, and the thermoplastic resin (A) is preferably a lactic acid resin and more preferably a polylactic acid.
本发明的目的是提供一种在不损害热塑性树脂固有的刚性的前提下提高耐热性(高结晶度)和透明性的树脂组合物,以及一种含有该树脂组合物的模塑制品。与本发明有关的热塑性树脂组合物包括热塑性树脂(A)和由三羟甲基氨基甲酸三(氨基酸酯)酰胺组成的成核剂(B)。成核剂(B)最好是三羟甲基氨基甲酸三(缬氨酸酯)酰胺或三羟甲基氨基甲酸三(亮氨酸酯)酰胺,热塑性树脂(A)最好是乳酸树脂,更优选聚乳酸。
