    • An ink curable with actinic energy rays which is characterized by containing a photocleavage type photopolymerization initiator (A) comprising α-aminoalkylphenone compound (A1) having a molar absorption coefficient as measured at a wavelength of 365 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 as 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 curable with actinic energy rays further includes a resin, a pigment, and a compound having an acrylate group. When used with a light emitting ultraviolet rays especially having a luminescence-peak wavelength in the range of 350 to 420 nm as an ultraviolet irradiator, the ink has excellent curability and printability in both monocolor printing and overprinting, the ink further has excellent storage stability.
    • 其特征在于,含有光分解型光聚合引发剂(A),其包含在波长365nm下测定的摩尔吸光系数为100(1 / mol·cm)的α-氨基烷基苯酮化合物(A1) 或更多少于100,000(1 / mol·cm)和/或具有在365nm波长下测得的摩尔吸光系数为100(1 / mol·cm)以上的酰基氧化膦化合物(A2)或更多且小于 100,000(1 / mol·cm); 和具有波长365nm的摩尔吸光系数为10,000(1 / mol·cm)以上且小于100万(1 / mol·cm)以上的4,4'-二烷基氨基二苯甲酮的取氢型光聚合引发剂(B) 并且通过任选地含有在365nm波长下测得的摩尔消光系数为1(1 / mol·cm)以下的叔胺化合物(C)。 用光化能射线可固化的油墨还包括树脂,颜料和具有丙烯酸酯基团的化合物。 当作为紫外线照射装置的发光紫外线特别是发光峰值波长在350〜420nm的范围内使用时,油墨在单色印刷和套印中均具有优异的固化性和印刷性,油墨还具有良好的储存稳定性。
