Abstract
The present invention discloses an ink printing method using an image-recording element, which provides an image having excellent image quality and superior dry time, comprising insoluble cationic core-shell polymeric particles each comprising a core comprising cationic core polymer having at least 10 mole percent of a cationic mordant monomeric unit and a shell comprising hydrophilic shell polymer that is substantially less cationic than the cationic core polymer, wherein the shell is at least 10% by weight of the core.
