PROBLEM TO BE SOLVED: To provide a resin composition capable of providing a high refractive index resin which can achieve both high refractive index and high transparency.SOLUTION: There is provided a resin composition comprising: a resin (A) having at least one kind selected from the group consisting of a thiourethane bond, a thiourea bond, a urethane bond, and a urea bond; a compound (B); and a base generator (C). The compound (B) comprises: at least one compound (b) selected from the group consisting of a compound (b1) having a phthalic acid skeleton, a compound (b2) having a trimellitic acid skeleton, and a compound (b3) having a pyromellitic acid skeleton; and a cation X, wherein carboxylate anions formed by ionization of protons of a part or all of carboxyl groups of the compound (b) and the cations X form coordinate bonds. The base generator (C) is a compound (C1) which generates a base by active energy rays or a compound (C2) which generates a base by heat. |
