摘要：There is provided a polymerizable composition for optical materials including

polyisocyanate (A), polythiol (B), an acidic phosphoric ester (C) represented by thefollowing General Formula (1), and one or more kinds of ultraviolet absorbers (D) havinga maximum absorption peak in a range of 350 nm to 370 nm, in which in a case where thetotal molar number of isocyanate groups in the polyisocyanate (A) is 100 mol%, asecondary isocyanate group is included in 20 mol% or more and the acidic phosphoricester (C) is included in an amount of 100 ppm to 700 ppm with respect to the totalweight of the polyisocyanate (A) and the polythiol (B).
