(57) [Summary] [Purpose] Image formation can be performed in response to a low-power laser or a laser in the infrared region. Provide a way. [Structure] Organic peroxide, onium salt, hexaarylbiimidazole, titanocene, compound having a structure in which a polyhalomethyl group is bonded to a heterocycle containing at least one of sulfur atom, oxygen atom and nitrogen atom, and polyhalomethyl A photopolymerizable composition containing a radical generator selected from sulfones, a compound having two or more ethylenically unsaturated double bonds, and a sensitizing dye is used to absorb light absorbed by the ground state of the sensitizing dye and the sensitizing dye. An image forming method comprising irradiating light absorbed by the triplet state of the dye at the same time. |
