PROBLEM TO BE SOLVED: To provide a photosensitive composition which can be cured up to the depth regardless of the presence or absence of a material which inhibits ultraviolet transmission, such as an organic or inorganic filler, carbon or metal particles, a short or long fiber, a polymer or oligomer or various modifying additives, and to provide a method for curing the photosensitive composition.SOLUTION: The photosensitive composition includes: an ultraviolet-curable material; and a chain transfer agent which enables chain curing of the ultraviolet-curable material in the presence of a material which inhibits ultraviolet transmission for inhibiting transmission of ultraviolet light. A curing active species generated when irradiating the ultraviolet-curable composition with ultraviolet light is propagated, by the chain transfer agent, up to a part where ultraviolet light does not reach, and thereby, the ultraviolet-curable composition is chain-cured regardless of the presence or absence of a material which inhibits ultraviolet transmission in the ultraviolet-curable composition. |
