Abstract

The present invention provides a curable composition containing a compound represented by general formula A and a compound represented by general formula B, wherein: in general formula A, Ar represents an n-valent group containing, as a moiety, a nitrogen-containing fused aromatic ring, L represents a linking group such as -O- or -C(=O)O-, Sp represents a single bond or a divalent linking group, Pol represents a hydrogen atom or a polymerizable group, and n represents 1 or 2, and the compound represented by general formula A has at least one polymerizable group; and in general formula B, R', R'', R''' each independently represent a hydrogen atom or a substituent, R' and R'', or R'' and R''', may be linked together to form an optionally substituted ring, and W represents a hydrogen atom ora substituent. The curable composition according to the present invention can be used to form a cured product having a low Abbe number, a high partial dispersion ratio, and high optical stability.

Description

technical field [0001] The present invention relates to a curable composition, a cured product, an optical member, a lens, and a compound. Background technique [0002] Conventionally, glass materials have been used for optical components of camera modules such as cameras, video cameras, mobile phones with cameras, video phones, and walkie-talkies with cameras. Glass materials have various optical properties and are excellent in environmental resistance, so they are suitably used, but they are not easy to reduce in weight or size, and have disadvantages of poor workability and productivity. On the other hand, since the resin cured product can be mass-produced and is excellent in workability, it has been gradually used in various optical components in recent years. [0003] In recent years, with the miniaturization of the camera module, the size of the optical components used in the camera module is required to be reduced, but when the optical components are reduced in size,...
