Provided is a clear ink that is excellent in ejection stability, can record an image having high glossiness, and can record an image having gloss uniformity regardless of a recording duty, as a clear ink for inkjet. . An ink-jet clear ink containing polymer fine particles, wherein the polymer fine particles are derived from a unit derived from an α, β-ethylenically unsaturated hydrophobic monomer (a), and an α, β-ethylenically unsaturated polymer. In the presence of a shell polymer that is a copolymer having a unit derived from a monomer selected from a saturated acid monomer and a salt thereof, polymerization is performed using the α, β-ethylenically unsaturated hydrophobic monomer (b) as a core polymer. A clear ink having a core-shell structure obtained by the step, wherein the α, β-ethylenically unsaturated hydrophobic monomer (b) contains an aromatic-containing unsaturated monomer.
