Zusammenfassung:	This resin composition contains a polyester polyol (A) and a polylactic acid polymer (B). The polyester polyol (A) contains a unit derived from a polyhydric alcohol (a1) and a unit derived from a polyvalent carboxylic acid (a2). The polyhydric alcohol (a1) contains a C4 or higher aliphatic diol (a1-1) having an alkyl group as a branching chain. Cette composition de résine contient un polyester polyol (A) et un polymère d'acide polylactique (B). Le polyester polyol (A) contient une unité dérivée d'un alcool polyhydrique (a1) et une unité dérivée d'un acide carboxylique polyvalent (a2). L'alcool polyhydrique (a1) contient un diol aliphatique en C4 ou plus (a1-1) ayant un groupe alkyle en tant que chaîne de ramification. ポリエステルポリオール（Ａ）と、ポリ乳酸系重合体（Ｂ）とを含有する樹脂組成物であって、前記ポリエステルポリオール（Ａ）が、多価アルコール（ａ１）及び多価カルボン酸（ａ２）に由来する単位を含み、前記多価アルコール（ａ１）が、アルキル基を分岐鎖として有する炭素数が４以上の脂肪族ジオール（ａ１－１）を含む、樹脂組成物。
