The present invention relates to a resin composition for an epoxyacrylic medium refractive optical lens and a method for producing the same. More particularly, the present invention relates to a resin composition for an epoxyacrylic medium refractive index optical lens having Abbe number in the range of 1.53 to 1.58, transparency, compression strength, light weight, Compositions and methods of making the same. In the present invention, an epoxyacrylic medium refractive optical lens comprising 30 to 70% by weight of a bisphenol A epoxy acrylate compound represented by the general formula (1), 3 to 30% by weight of methyl methacrylate and 5 to 50% by weight of a reactive diluent, Is provided. According to the present invention, it is possible to manufacture a high-quality medium refractive optical lens having excellent Abbe's number, transparency, compressive strength, light weight, and heat resistance without increasing the conventional medium refractive index lens production cost by using an epoxy acrylic monomer. The epoxyacrylic medium refractive optical material prepared according to the present invention can be widely used in various fields in place of the conventional middle refractive optical material. |
