PROBLEM TO BE SOLVED: To establish a technique for obtaining a highly transparent cured product through high copolymerizability even from a resin composition comprising an unsaturated polyester and a (meth)acrylic monomer. SOLUTION: The resin composition comprising the unsaturated polyester and the (meth)acrylate monomer is obtained by further including an N-vinyl monomer of formula (1a) or (1b) (wherein, R<1> to R<3> are each H or an organic group; R<4> is H or an organic group; and R<5> is an organic group, wherein R<4> and R<5> may be joined each other to form a ring). |
