| abstract |
A curable resin composition comprising a (meth)acrylate monomer having an aromatic ring, a non-conjugated vinylidene group-containing compound represented by the general formula below, and a thermal or a photo-radical polymerization initiator makes it possible to produce a cured product with minimized occurrence of burring during molding and high product yield after molding. The cured product has good heat coloration resistance and low Abbe's number. R 11 , R 12 , R 15 , and R 16 represent a substituent and A represents an atomic group necessary for forming a cyclic structure. |
