Abstract
An ink curable with actinic energy rays characterized by containing a photocleavage type photopolymerization initiator (A) comprising α-aminoalkylphenone compound (A1) having a molar absorption coefficient measured at a wavelength of 363 nm of 100 (l/mol·cm) or more and less than 100,000 (l/mol·cm) and/or an acylphosphine oxide compound (A2) having a molar absorption coefficient measured at a wavelength of 365 nm of 100 (l/mol·cm) or more and less than 100,000 (l/mol·cm); and a hydrogen abstraction type photopolymerization initiator (B) comprising 4,4'-dialkylaminobenzophenone having a molar absorption coefficient at a wavelength of 365 nm of 10,000 (l/mol·cm) or more and less than 1,000,000 (l/mol·cm) and by optionally containing a tertiary amine compound (C) having a molar extinction coefficient as measured at a wavelength of 365 nm of 1 (l/mol·cm) or lower. The ink further includes a resin, a pigment, and a compound having an acrylate group.
