Patent ID: 7833591

Claim:
An inkjet recording element comprising a support having thereon at least one porous image-receiving layer comprising: (a) insoluble cationic core-shell polymeric particles, each comprising a core and a shell, the core comprising a cationic core polymer having at least 10 mole percent of a cationic mordant monomeric unit and the 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; and (b) inorganic and/or organic particles other than the insoluble cationic core-shell polymeric particles in a total amount of greater than 50 percent by weight of the porous image-receiving layer, and the weight ratio of the insoluble cationic core-shell polymeric particles to inorganic and/or organic particles in the image-receiving layer is 1:2 to 1:20.
