Compound for optical materials, curable composition, cured body, and optical article

Abstract

The present invention provides a novel compound for optical materials, and a curable composition, a cured body and an optical article containing the compound for optical materials. According to an embodiment, there is provided a compound for optical materials represented by Formula (Ia) below: In Formula (Ia), X1 and X2 are each NH, S, or O. R1 is a 1- to 30-valent organic residue. R3 is a group composed of a polymer having a repeating unit selected from the group consisting of —(CH2)mO—, —(CH2CH2O)—, —(CH(CH3)CH2O)—, —(CH2CH(CH3)O)—, —(C(═O)—CH2CH2CH2CH2CH2O)—, —(C(═O)—O—CH2CH2CH2CH2CH2O)—, and (C(═O)—O—CH2CH2CH2CH2CH2CH2O)—, a random copolymer having at least two repeating units selected from the group, or a block copolymer having at least two repeating units selected from the group.
