Resin composition for optical material having advanced property and preparation method of optical material using it

摘要

The present invention relates to a resin composition for polymerization with an optical material having improved optical properties such as light resistance, transmittance and heat resistance, and a process for producing an optical material using the same. In the present invention, by using a simple method of reducing the content of a metal component contained in a phosphoric acid ester compound used as an internal mold release agent to 0.01% by weight (100 ppm) or less in the polymerization composition, an important optical property Can be improved.
