A photocurable composition which cures upon irradiation with not only ultraviolet but visible light, which comprises (A) an ethylenic compound, (B) a free-radical polymerization initiator, and (C) a tertiary thiophosphite. The initiator (B) is (B-1) a free-radical photopolymerization initiator having absorption wavelengths not shorter than 400 nm, (B-2) a free-radical photopolymerization initiator having absorption wavelengths shorter than 400 nm, or a mixture of the initiators (B-1) and (B-2). The composition is usable in a wide range of applications such as adhesives, coating materials, paints, molding materials, dental materials, and image-forming materials. |
