  The present invention provides a cured product obtained by curing a curable composition including a compound represented by General Formula 1, in which a birefringence Δn (587 nm) is 0.00≤Δn (587 nm)≤0.01. Pol1-Sp1-L1-Ar-L2-Sp2-Pol2  (General Formula 1) In the formula, Ar represents a divalent group containing a ring structure selected from the group consisting of a quinoxaline ring and a quinazoline ring; L1 and L2 each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp1 and Sp2 each represent a single bond or a divalent linking group; Pol1 and Pol2 each represent a hydrogen atom or a polymerizable group; and the compound represented by General Formula 1 has at least one polymerizable group. The cured product of the present invention has a small Abbe number (νd) and a large partial dispersion ratio (θg, F), and is therefore useful for production of optical members.

  本发明提供了一种通过对可固化组合物进行固化而获得的固化产物，所述可固化组合物包含由通用式1表示的化合物，其中双折射率Δn (587 nm)满足0.00≤Δn (587 nm)≤0.01。 Pol1-Sp1-L1-Ar-L2-Sp2-PoL2  (通用式1) 在上述式中，Ar表示从喹喔啉环和喹嗪环中选择的包含环结构的二价基团；L1和L2各自表示单键、—O—、—OC(＝O)—、—OC(＝O)O—、—OC(＝O)NH—等；Sp1和Sp2各自表示单键或二价连接基团；Pol1和PoL2各自表示氢原子或可聚合基团；并且由通用式1表示的化合物具有至少一个可聚合基团。本发明的固化产物具有较小的阿贝数(νd)和较大的部分色散比(θg, F)，因此在光学元件的生产中具有用途。
