A photocurable composition is provided that includes a polymerizable compound, a photopolymerization initiator, a compound represented by Formula (I) below, and an amine compound, the photopolymerization initiator comprising an acylphosphine oxide compound and/or an α-aminoacetophenone compound n n n n n n n n n n in Formula (I) above, X denotes O, S, or NR, n denotes 0 or 1, R denotes a hydrogen atom, an alkyl group, or an acyl group, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 independently denote a hydrogen atom or a monovalent substituent, and two of R 1 , R 2 , R 3 , and R 4 that are adjacent may be bonded to each other to form a ring. There are also provided a photocurable ink composition that includes the photocurable composition and a colorant, an ink composition for photocuring inkjet recording that includes the photocurable ink composition, a process for producing a photocured material that includes preparing the photocurable composition and irradiating the photocurable composition with light having a light emission peak in the range of at least 340 nm but no greater than 400 nm, and an inkjet recording method that includes discharging the ink composition onto a recording medium and irradiating the ink composition with actinic radiation. |
