A curable composition containing an inorganic compound A having sulfur atom and/or selenium atom, a compound B represented by the following formula 1: 

Curable composition

There is provided a coating composition having a good wetting property which is capable of forming a coating film exhibiting a high refractive index, a less discoloration, and excellent transparency and uniformity when polymerized and cured. The present invention relates to a coating composition comprising (A) 100 parts by weight of a thiirane ring-containing compound, (B) 0.0001 to 10 parts by weight of a catalyst for accelerating polymerization of the thiirane ring-containing compound, and (C) 0.005 to 4 parts by weight of a modified silicone oil; a coating film produced from the composition; and an optical product provided with the coating film.

Coating composition, coating film made of same, and optical article

There are provided a photocurable composition capable of being readily cured by irradiation of ultraviolet rays and a cured product of the photocurable composition, as well as a coating composition and a coating film obtained from the coating composition. The cured product exhibits a high refractive index, a less discoloration and an excellent transparency. The present invention relates to a photocurable composition comprising (A) an episulfide compound containing a thiirane ring; and (B) a photo-base generator represented by the general formula (1): wherein Ar is phenyl, etc.; R is an alkyl group, etc.; &#x2014;Ais an ammonium ion; and Xis a borate anion, etc., and a coating composition comprising the photocurable composition and (C) a modified silicone oil, as well as a cured product and a coating film obtained from these compositions.
