In photosensitive compositions, such as an ultraviolet curable composition to harden | cure in a short time, the photosensitive composition which can harden | cure the part which does not generate | occur | produce radicals, such as a dark part which irradiation light does not reach at all, and the hardened | cured material using the same are provided. It contains an ultraviolet curable material, the compound containing at least 1 sort (s) selected from a urethane bond, a urea bond, and an isocyanate group as (a) component, and the chain transfer agent containing a metal compound as (b) component, and irradiation light arrives. The photosensitive composition was hardened | cured by irradiation of the ultraviolet-ray using the photosensitive composition which the site | part which is not curable is obtained, and the hardened | cured material was obtained. |
