Abstract
Provided is an ink jet clear ink containing a polymer fine particle. The polymer fine particle has a core-shell structure obtained by polymerizing an α,β-ethylenically unsaturated hydrophobic monomer (b) as a core polymer in the presence of a shell polymer that is a copolymer having at least a unit derived from an α,β-ethylenically unsaturated hydrophobic monomer (a) and a unit derived from a monomer selected from an α,β-ethylenically unsaturated acid monomer and a salt thereof. The α,β-ethylenically unsaturated hydrophobic monomer (b) includes at least a monomer containing a chain structure saturated alkyl group.
