COMPOSITION FOR OPTICAL MATERIAL

摘要

The composition for optical materials of the present invention contains at least one compound represented by the following Formula 1: <CHEM> wherein R<1>, R<2> and R<3> are each independently C1-C10 hydrocarbyl or hydrogen; X<1>, X<2> and X<3> are each independently S, Se or Te; Y<1>, Y<2> and Y<3> are each independently -Sa-Ä(CH2)bSÜcH, a is an integer from 0 to 2, b is an integer from 0 to 4, and c is an integer from 0 to 2, and a compound reactive to the compound of Formula 1. A resin produced by curing a composition containing the compound of Formula 1 by polymerization has a high refractive index, and suitable as various optical materials.
