2. The undercoat solution according to claim 1 , further comprising a radical polymerization initiator.
3. An ink-jet recording method, comprising:
applying, onto a recording medium, an undercoat solution;
partially curing the applied undercoat solution; and
discharging an ink, which is curable by irradiation with an active energy ray, onto the partially cured undercoat solution to record an image,
wherein the undercoat solution comprises an acrylamide polymer that is oil-soluble and water-insoluble and a radical-polymerizable compound having a phosphoric acid group that is applied in advance onto the recording medium prior to discharging the ink onto the recording medium to record the image, the radical-polymerizable compound having a phosphoric acid group selected from the group consisting of a phosphoric acid group-containing radical-polymerizable compound in which all of the hydroxyl groups of phosphoric acid have been esterified, and a bifunctional or higher functional phosphoric acid group-containing radical-polymerizable compound.
4. The ink-jet recording method according to claim 3 , wherein the undercoat solution is partially cured by irradiating with an active energy ray.
5. The ink-jet recording method according to claim 3 , wherein the undercoat solution further contains a radical polymerization initiator.
6. The ink-jet recording method according to claim 3 , wherein in the discharging of the ink, an ink set containing multiple colored inks is used to perform the discharging, and at least one of the discharged colored inks is partially cured.
7. The ink-jet recording method according to claim 3 , wherein curing of the undercoat solution and the discharged ink is carried out to fix the recorded image onto the recording medium.
8. The ink-jet recording method according to claim 3 , wherein the curing sensitivity of the ink is equal to or greater than the curing sensitivity of the undercoat solution.
9. An ink-jet recording method, comprising:
applying, onto a recording medium, an undercoat solution;
partially curing the applied undercoat solution; and
discharging an ink, which can be cured by irradiation with an active energy ray, onto the partially cured undercoat solution to thereby record an image,
wherein the undercoat solution comprises an acrylamide polymer that is oil-soluble and water-insoluble and a radical-polymerizable compound having a phosphoric acid group that is applied in advance onto the recording medium prior to discharging the ink onto the recording medium to record the image, the radical-polymerizable compound having a phosphoric acid group selected from the group consisting of a phosphoric acid group-containing radical-polymerizable compound in which all of the hydroxyl groups of phosphoric acid have been esterified, and a bifunctional or higher functional phosphoric acid group-containing radical-polymerizable compound.
