Ink set, image recording method and image recording apparatus

摘要

Provided is an ink set that comprises an ink jet ink containing a pigment in a dispersed state and a reactive liquid to be employed with the ink to cause aggregation of the pigment in the ink in contact with the ink on a recording medium, wherein the ink further contains a graft polymer, and 50 mass% or more monomer units constituting a main chain of the graft polymer are monomer units having a hydrophilic functional group and 50 mass% or more of monomer units constituting side chains of the graft polymer are monomer units having a hydrophobic functional group, suitable for high quality ink jet printing.
