PURPOSE:To obtain a lens high in refractive index and good in water resistance or the like, by radiating a curable composition that is obtained by mixing a di(meth)acrylate with an epoxy (meth)acrylate with an activating energy ray. CONSTITUTION:A di(meth)acrylate (1) is obtained by adding bisphenol A and/or bisphenol F to an alkylene oxide and reacting acrylic acid and/or methacrylic acid therewith. On the other hand, an epoxy (meth)acrylate (2) is obtained by reacting an epoxy resin, which is obtained by the condensation of bisphenol A and/or bisphenol F with epichlorohydrin, with acrylic acid and/or methacrylic acid. Compounds (1) and (2) are mixed, the mixture is injected into a mold for a lens, and is irradiated with an activating energy ray to be cured, and the thus obtained lens is removed. |
