Abstract:
1. An ink jet recording method, comprising discharging an ultraviolet curing ink jet ink composition on a recording medium, and then performing a curing reaction of the ultraviolet curing ink jet ink composition by irradiation of light having a wavelength of from 350 to 450 nm at an irradiation amount of 50 to 15,000 mJ/cm 2 with an ultraviolet light-emitting diode, wherein the ultraviolet curing ink jet ink composition contains 3 to 30% by weight of an urethane oligomer, 50 to 95% by weight of a polymerizable compound other than the urethane oligomer as a polymerizable monomer, and 1 to 20% by weight of a photopolymerization initiator comprising an acylphosphineoxide; and the ultraviolet curing ink jet ink composition is free from an aqueous solvent, and wherein the polymerizable compound comprises an allyl compound and/or an N-vinyl compound, and the content of the allyl compound and/or the N-vinyl compound in the ultraviolet curing ink jet ink composition is from 20 to 80% by weight.
