Patent ID: 8034422

Claim:
An inkjet-receiving medium comprising: (a) a support, which is optionally porous, comprising a water-soluble, essentially colorless, non-reactive salt of a multivalent metal cation on its surface and/or incorporated within a porous structure thereof; and (b) on one or each side of the support at least one porous ink-receiving layer, including a porous ink-receiving top layer consisting essentially of non-cationic components and the same water-soluble salt of a multivalent metal cation that in substantial part has diffused into the porous ink-receiving top layer from the support, wherein the non-cationic components comprise binder and anionic particles of average particle size less than 2.5 micrometers, and wherein the anionic particles comprise at least 50 percent of the total solids by weight in the porous ink-receiving top layer.
