<p>The present invention relates to a method for manufacturing an optical material by polymerizing a resin composition comprising a compound containing thiol and a composition having an isocyanate group and, more specifically, to a method for manufacturing a high-quality urethane-based optical material using a universal polyisocyanate compound. The present invention provides the method for manufacturing the resin for the urethane-based optical material, which in-mold polymerizes a polythiol compound and a universal polyisocyanate compound as the main ingredients, the resin composition having 300-3,000 ppm of water, and provides the optical material manufactured thereby. According to the present invention, by using the universal isocyanate compound, which is supplied at a low price, tape whitening or the formation of bubbles can be minimized while performing the in-mold polymerization using tape, and a high-quality and transparent urethane-based optical material without any color can be manufactured at a high yield.</p> |
