Abstract
An ink set of radiation curable ink jet compositions, includes: an under layer ink; and an over layer ink, and the under layer ink contains, as a polymerizable compound, 80.0 percent by mass or more of a monofunctional polymerizable compound with respect to a total mass of polymerizable compounds and contains 55.0 percent by mass or more of a polymerizable compound having a nitrogen heterocyclic structure and/or a polymerizable compound having a hydroxy group in total with respect to the total mass of the polymerizable compounds.

An ink set of radiation curable ink jet compositions, comprising:
- an under layer ink;
- and
- an over layer ink,
- wherein the under layer ink contains, as a polymerizable compound, 80.0 percent by mass or more of a monofunctional polymerizable compound with respect to a total mass of polymerizable compounds and contains 55.0 percent by mass or more of a polymerizable compound having a nitrogen heterocyclic structure and/or a polymerizable compound having a hydroxy group in total with respect to the total mass of the polymerizable compounds, and
- wherein the polymerizable compound having the nitrogen heterocyclic structure and/or the polymerizable compound having the hydroxy group is contained in the underlayer ink in an amount of at least 20 percent by mass relative to a total mass of the underlayer ink.
