PROBLEM TO BE SOLVED: To provide a photopolymerizable composition having high sensitivity to light in the region from visible light to infrared light as well as to ultraviolet light. SOLUTION: The photopolymerizable composition contains a polymerizable compound having an ethylenically unsaturated bond, a compound of formula 1 (where Q1-Q3 are each O or S; R1 and R2 are each H, an aliphatic group, an aromatic group or a heterocyclic group; and Z1 and Z2 are each a substituent required to allow the compound of the formula 1 to become a dye) and an organoboron compound of formula A (where Ra1-Ra3 are each an aliphatic group, an aromatic group, a heterocyclic group or -SiRa5Ra6Ra7; Ra5-Ra7 are each an aliphatic group or an aromatic group; Ra4 is an aliphatic group; and Y+ is a group capable of forming a cation). |
