Abstract
An ink composition is provided that includes (A), an N-vinyllactam, (B) another polymerizable compound, (C) a polymerization initiator, (D) a basic compound, and (E) an oil-soluble dye having an oxidation potential of equal to or higher than 1.0 V (vs. SCEs); wherein of the total weight of the N-vinyllactam (A) and the other polymerizable compound (B) not less than 65 wt % is a monofunctional polymerizable compound. There is also provided an inkjet recording method that includes a step of discharging the ink composition onto a recording medium and a step of curing the ink composition by irradiating the discharged ink composition with actinic radiation. There is also provided a printed material recorded by the inkjet recording method.
