The present invention provides a photocurable composition which is rapidly cured. The composition comprises a polymerizable compound having an ethylenically unsaturated double bond and a photopolymerization initiator wherein the photopolymerization initiator comprises;
(a) a compound having the following formula [I];
[wherein X represents a sulfur atom or -CO-, R¹, R², R³ and R⁴ respectively represent a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, an alkoxy group, -CH₂COOH, a nitro group, a sulfonyl group, a phosphonyl group, a cyano group, a hydroxyl group and a halogen atom.], or an alpha-diketone compound having the formula [II];
R⁵---R⁶ [II]
[wherein R⁵ and R⁶ respectively represent an alkyl group, an alkoxy group or an aryl group, provided that neither R⁵ nor R⁶ is an alkoxy group.]
(b) carbon tetrachloride or a compound having tribromomethylsulfonyl, and
(c) an amine having carbon atoms directly bonded to a nitrogen atom, at least one of which is methylene group.
