COMPOSITION FOR USE IN OPTICAL MATERIAL WITH HIGH REFRACTIVE INDEX AND HIGH STRENGTH |
摘要 |
Disclosed is a composition for use in an optical material capable of providing an optical material satisfying a high refractive index (ne is 1.73 or more), a high strength (an elongation is 10% or more in a three-point bending test and drilling resistance is good), and high thermostability (a softening point measured by TMA is 70°C or higher). The optical material such as a lens for two-point frame spectacles is formed by polymerizing and curing a composition for use in an optical resin material containing (a) an inorganic compound having a sulfur atom and/or a selenium atom, (b) an episulfide compound, and (c) a xylylenedithiol compound. |
