  An object is to provide a polymerizable liquid crystal compound, a polymerizable liquid crystal composition containing the compound and liquid crystal polymerization film-kind capable of controlling chromatic dispersion characteristics and having low positive chromatic dispersion characteristics. An aspect can be exemplified in which the polymerizable liquid crystal compound is represented by formula (1): in which, in formula (1), G is a group composed of a quinoline skeleton, an isoquinoline skeleton, a quinoxaline skeleton or a quinazoline skeleton, A1 is 1,4-phenylene or 1,4-cyclohexylene, Z1 is a connecting group, m is an integer from 0 to 3, and R1 is a group containing a polymerizable group.

  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。
