The present invention provides a resin composition for molding, added with a nucleating agent suitable for promoting crystallization of polyester capable having a crystal structure, and in particular of biodegradable polyester, and also provides a molded product containing the resin composition for molding thus improved in the crystallinity. The resin composition is characterized by comprising polylactic acid and either
a cyclic compound expressed by general formula (I) below:
[where each of A 1 , A 2 , A 4 and A 5 is independently -CO- or -NH-, each of A 3 and A 6 is independently hydrogen, halogen, an optionally-substituted aliphatic group or an optionally-substituted aromatic group] and having both of -CO- and -NH- in the molecule, or
a mixture of (i) a cyclic compound having -CO- but no NH in the molecule and (ii) a cyclic compound having no -CO- but NH in the molecule.
