NOVEL SULFUR-CONTAINING AND ETHYLENICALLY UNSATURATED GROUP-CONTAINING COMPOUND, RADIATION-CURABLE COMPOSITION, AND CURED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a radiation-curable composition which can be suitably used for producing a cured material capable of having a high refractive index and a high Abbe number. SOLUTION: There are provided a sulfur-containing and ethylenically unsaturated group-containing compound (A) prepared by reacting a sulfur-containing compound represented by formula (1) with a compound having an ethylenically unsaturated group, a radiation-curable composition containing compound (A) and a cured material. Also provided are a radiation-curable composition comprising the compound (A) and a photopolymerization initiator and a radiation-curable composition comprising a compound which is other than the compound (A) and has an alicyclic structure and an ethylenically unsaturated group.
