Abstract
Disclosed herein is a curable composition containing a monomer (A) having at least one crosslinkable group and at least one aromatic ring, a monomer (B) having a fluorene skeleton, a compound (C) having an Abbe number of at most 21, and a polymerization initiator (D), wherein the content of the compound (C) is from 1 to 10 mass % based on 100 mass % of the total content of the monomer (A), the monomer (B) and the compound (C). Curable compositions of this disclosure have low viscosities and produce cured products having a high refractive indices, a low Abbe numbers, high transparencies and high heat resistances.
