Title:
高屈折率高強度光学材料用組成物
Document Type and Number:
Japanese Patent JP5720565
Kind Code:
B2
Abstract:
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) anepisulfide compound, and (c) a xylylenedithiol compound.
