Abstract
A nonaqueous ink jet ink composition is used for a recording method which performs a long printing operation without a step of taking measures against nozzle missing, and the ink jet ink composition described above includes a polymerizable monomer, a liquid photoinitiator in the form of a liquid at 20° C., and a solid photoinitiator in the form of a solid at 20° C. at a content of zero percent by mass or more and 1.5 percent by mass or less with respect to a total mass of the nonaqueous ink jet ink composition.

A nonaqueous ink jet ink composition used for a recording method which performs a long printing operation without a step of taking measures against nozzle missing, the ink composition comprising:
- a polymerizable monomer;
- a liquid photoinitiator in the form of a liquid at 20° C.;
- and
- a solid photoinitiator in the form of a solid at 20° C. at a content of zero percent by mass or more and 1.5 percent by mass or less with respect to a total mass of the nonaqueous ink jet ink composition,
- wherein the polymerizable monomer includes a monofunctional monomer,
- the monofunctional monomer includes vinyl methyl oxazolidinone, and
- the vinyl methyl oxazolidinone is present at a content of 5 to 30 percent by mass with respect to the total mass of the nonaqueous ink jet ink composition.
