An inkjet recording method is provided that includes an image formation step of forming an image on a recording medium by discharging an ink composition that includes (Component A) and (Component B), and a curing step of curing the discharged ink composition by irradiating with UV using a light-emitting diode that emits UV having an emission peak wavelength in the range of 300 to 400 nm so that the maximum illumination intensity on the recording medium surface is 600 to 1,600 mW/cm 2 .
(Component A) a polymerizable composition that includes Component A-1 to Component A-3
(Component A-1) an N -vinyllactam,
(Component A-2) a compound represented by Formula (a-2)
(In Formula (a-2), R 1 , R 2 , and R 3 independently denote a hydrogen atom, a methyl group, or an ethyl group, and X 2 denotes a single bond or a divalent linking group.),
(Component A-3) a polyfunctional (meth)acrylate, the total content of monofunctional polymerizable compounds including Component A-1 and Component A-2 being at least 40 wt% in the ink composition,
(Component B) a polymerization initiator that includes Component B-1 and Component B-2
(Component B-1) an acylphosphine compound,
(Component B-2) a thioxanthone compound and/or a thiochromanone compound,
{(Component B-1 total weight) ‰¥ (Component B-2 total weight)} being satisfied. There is also provided a printed material recorded by the inkjet recording method. |
