Polymerizable composition for high-refractive optical material and method for preparing high-refractive optical material

Abstract

The present invention relates to a novel polymerizable composition for an optical material with a high refractive index and a method of preparing the optical material. More particularly, the present invention provides a polymerizable composition for an optical material with a high refractive index, including a compound represented by Formula 1 or 2 and a compound represented by Formula 3 and an optical material, particularly a glass lens, with a high refractive index obtained through polymerization of the polymerizable composition. In addition, the present invention provides a polymerizable composition for a photochromic optical material with a high refractive index composition and a photochromic optical material, particularly a photochromic glass lens, with a high refractive index obtained through polymerization of the polymerizable composition.
