PROBLEM TO BE SOLVED: To improve hydrolysis resistance of molding that consists of hydrolyzable resin such as polylactic acid resin.SOLUTION: A resin composition includes: a hydrolyzable resin (A) such as polylactic acid resin; aromatic carbodiimide compound (B); and metal oxide (C) such as titanium oxide. In addition, it may include a graft copolymer (D1) obtained by polymerizing a vinyl monomer (b1), or the mixture of the graft copolymer (D1) and (co)polymer (D2) of a vinyl monomer (b2) in the presence of a rubbery polymer (a). It is preferable that the content of the component (B) is 1 to 10 pts.mass, and the content of the component (C) is 0.5 to 30 pts.mass, when the total of the components (A) and (D) is assumed to be 100 pts.mass. |
