POLYMERIZABLE COMPOSITION FOR HIGHLY REFRACTIVE OPTICAL MATERIAL, PHOTOCHROMIC COMPOSITION THEREOF, AND METHOD FOR PREPARING HIGH-REFRACTIVE OPTICAL MATERIAL USING COMPOSITIONS

摘要

The present invention relates to a polymerizable composition for a highly refractive optical material, a photochromic composition thereof, and a method for preparing a highly refractive optical material using the compositions. In the present invention, provided is a polymerizable composition for a highly refractive optical material, the polymerizable composition containing at least one of compounds represented by chemical formulas 1 and 2, and provided is a photochromic composition further containing a photochromic compound in addition to the polymerizable composition. According to the present invention, a fluorene acryl based optical material can be obtained that has excellent photochromic performance and optical characteristics while being highly refractive.
