Abstract
An ink jet process includes an ejection step, in which a radiation-curable ink jet composition is ejected from an ink jet head to a recording medium, and a curing step, in which the ejected ink jet composition is irradiated with radiation to give a cured coating of the ink jet composition. The ink jet composition contains at least one polymerizable compound, at least one photopolymerization initiator, and C.I. Pigment Red 57:1. The C.I. Pigment Red 57:1 constitutes 4.0% by mass or more of the total amount of the ink jet composition, and the cured coating has a maximum thickness of 5 μm or less.
