WIPO Patent Application WO/2019/066039

A1

An embodiment of the present invention relates to a method for manufacturing an optical member resin having excellent dyeability, and to an optical member resin, a spectacle lens, and spectacles. The present invention is: a method for manufacturing an optical member resin, including a step for polymerizing a polymerizable composition containing a polyisocyanate component, and a polythiol component including at least 40 mol% of a polythiol compound having two or more sulfide bonds in the molecular structure thereof, wherein the content of a hydrolyzable chlorine compound included in the polyisocyanate component is in the range of 10 mass ppm to 100 mass ppm in the polyisocyanate component; an optical member resin obtained by the manufacturing method; an optical member comprising the optical member resin; a spectacle lens provided with a lens base material comprising the optical member resin; and spectacles provided with the spectacle lens.
