To provide a photosensitive composition containing a highly sensitive photopolymerization initiator that efficiently absorbs and activates light having a long wavelength such as 405 nm and 365 nm. A photosensitive composition comprising a photopolymerization initiator comprising at least one oxime ester compound represented by the following general formula (I) and a polymerizable compound having an ethylenically unsaturated bond. (Wherein R 1 and R 2 each independently represent R 11 , OR 11 , COR 11 , SR 11 , CONR 12 R 13 or CN; R 11 , R 12 and R 13 are each independently Represents an alkyl group, R 3 and R 4 each independently represents R 11 or the like, a halogen atom or a hydroxyl group, and a and b each independently represent 0 to 4. X 1 represents a direct bond or Represents CO, X 2 represents an oxygen atom, a sulfur atom, a selenium atom, CR 31 R 32 , CO, NR 33 or PR 34 , and R 31 , R 32 , R 33 and R 34 each independently represent R 11 etc.) [Selection figure] None |
