Image forming method using actinic energy radiation curable ink-jet ink and printed matter obtained thereby

摘要

Provided is an actinic radiation curable inkjet ink capable of high sensitivity and high glossy image; and an image forming method utilizing the same. An actinic radiation curable inkjet ink comprising a photo polymerization initiator and a polymerizable monomer, wherein a surface free energy ³ s of an ink layer cured by an actinic radiation is in the range of 30 to 50 mJ/m 2 and a polar component ³ s p is in the range of 5 to 15 mJ/m 2 ; wherein ³ s d , ³ s p and ³ s h each represent a non-polar component, a polar component and a hydrogen bond component of a surface free energy of a solid surface based on Young-Fowkes Equation, provided that the surface free energy is represented by ³ s =³ s d +³ s p +³ s h .
