<p>A thermoplastic resin composition which comprises [A] a rubbery-polymer-reinforced graft resin (such as ABS resin) that is obtained by polymerizing a polymerizable unsaturated monomer in the presence of a rubbery polymer, [B] an aliphatic polyester resin (such as polylactic acid), and [C] a polymer (such as methyl methacrylate copolymer) that comprises structural units (cx) derived from a (meth)acrylic ester, wherein the polymer [C] consists of a polymer (C-1) that contains structural units (cx) in an amount exceeding 0% by mass and up to r1% by mass, a polymer (C-2) that contains structural units (cx) in an amount exceeding r1% by mass and up to r2% by mass, and a polymer (C-3) that contains structural units (cx) in an amount exceeding r2% by mass and up to 100% by mass, with r1 and r2 satisfying the relationship: r2 - r1 = 15(% by mass), and the contents of polymers (C-1), (C-2) and (C-3) are 5 to 80% by mass, 3 to 70% by mass, and 5 to 80% by mass, respectively.</p> |
