Clear ink, ink jet recording method, ink set, ink cartridge, recording unit and ink jet recording apparatus

摘要

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 alpha,beta-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 alpha,beta-ethylenically unsaturated hydrophobic monomer (a) and a unit derived from a monomer selected from an alpha,beta-ethylenically unsaturated acid monomer and a salt thereof. The alpha,beta-ethylenically unsaturated hydrophobic monomer (b) includes at least a monomer containing a chain structure saturated alkyl group.
