RESIN COMPOSITION FOR OPTICAL MATERIAL HAVING ADVANCED PROPERTY AND PREPARATION METHOD OF OPTICAL MATERIAL USING IT

摘要

PURPOSE: A resin composition for optical material is provided to improve optical properties through a metal component content control of a phosphate ester compound which is used as an internal releasing agent. CONSTITUTION: A resin composition for optical material comprises phosphate ester compound in chemical formula 1of which metal component content is 0.01 weight%(100 ppm) or less, an internal releasing agent. In chemical formula 1, X is an alkyl group, R is an alkyl group, alkylphenol, or phenylalkyl, n is 0-40, and m is 1-3. The metal component comprises one selected from Al, Zn, Cu, Fe, Bi, and Zr.
