Abstract: An object of the present invention is to provide a light-curable resin composition having reduced soot residue at the time of mold preparation and reduced occurrence of cracks and fractures. The present invention has found that a light-curable resin composition including a (meth)acrylate-based UV-curable resin (A) (with proviso that the following compound (B) is omitted), and a compound (B) having an alkylene glycol skeleton represented by a specific chemical formula in a structure allows the soot residue at the time of mold preparation to be reduced and occurrence of cracks and fractures to be reduced, whereby the above object is achieved.
