Abstract:
1. An inkjet recording medium consisting essentially of: a support; and one or more porous hydrophilic polymer ink receiving layer(s) supported on said support, said one or more porous hydrophilic polymer ink receiving layer(s) consisting essentially of a porous foamed hydrophilic polymer in which the hydrophilic polymer is swellable, decomposition product of a blowing agent, and, optionally, a surfactant, wherein the porous foamed hydrophilic polymer is formed by the decomposition of a blowing agent in a layer coated from a solution of said swellable hydrophilic polymer, wherein the one or more porous hydrophilic polymer ink receiving layer(s) are capable of absorbing dye from an applied ink within the polymer.
