There is provided a process for producing a polyurethane lens which is obtained by polymerizing a composition comprising a polyisocyanate compound and a specific polythiol compound having a high reactivity, . (A) a polyisocyanate compound, (B) a polythiol compound containing a polythiol compound obtained by esterification of a polyol compound and a thioglycolic acid, (C) a polymerization catalyst, and (D) 0.001 to 0.5 parts by mass with respect to 100 parts by mass of an acidic phosphoric acid ester compound represented by the following general formula (1) ), And then adding the components (B) and (C) to prepare the composition. (In the general formula (1), R 1 represents an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 10 carbon atoms, a represents 0 to 2, and b represents 1 or 2.) |
