Title:
RESIN COMPOSITION FOR EPOXY ACRYL-BASED MEDIUM-REFRACTIVE OPTICAL LENS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/216897
Kind Code:
A3
Abstract:
The present invention relates to an epoxy acryl-based optical lens and, especially, to a resin composition for an epoxy acryl-based medium-refractive optical lens having favorable moldability, thermal stability, light resistance, and compressive strength, with a solid-state refractive index of 1.53-1.58, and to a preparation method therefor. Provided in the present invention is a resin composition for an epoxy acryl-based medium-refractive optical lens having a solid-state refractive index of 1.53-1.58, the resin composition containing: 50-70 wt% of bisphenol A epoxyacrylate having an epoxy group-containing compound content of 0.7 wt% or less, 21-45 wt% of methyl methacrylate, and 1-17 wt% of a reactive diluent. According to the present invention, an epoxy acryl-based medium-refractive optical lens having excellent moldability, thermal stability, and light resistance as well as high compressive strength, while maintaining transparency and Abbe's number in good condition can be produced at a low production cost, by controlling the content of the epoxy group-containing compound remaining in the preparation procedure of epoxy acrylate and allowing a large amount of MMA to be contained in the composition. The epoxy acryl-based medium-refractive optical lens according to the present invention can be widely used in various fields by substituting for an existing medium-refractive optical lens.
