Claim:
1. A resin composition including an aliphatic polyester mainly derived from water-soluble monomers (component C) and a hydrolysis regulator having reactivity with an acidic group in a 15% hydrochloric acid aqueous solution at 100° C. of 30% or more (component D), the resin composition satisfying any one of the following J1 to J2: J1: In the 15% hydrochloric acid aqueous solution at 100° C., after 6 hours, a weight average molecular weight retention rate of the resin composition is 50% or more, and after 24 hours, a weight of a water-insoluble matter of the resin composition is 50% or less; and J2: In the 15% hydrochloric acid aqueous solution at 120° C., after 1 hour, a weight average molecular weight retention rate of the resin composition is 50% or more, and after 24 hours, a weight of a water-insoluble matter of the resin composition is 50% or less; wherein the hydrolysis regulator (component D) comprises 3,4-epoxycyclohexenylmethyl-3′,4′-epoxycyclohexene carboxylate.
