An inkjet recording element comprising a support coated with an immiscible polymer blend to overcome limitations of existing hydrophilic materials for extrusion coating. The two phases correspond, respectively to a first composition comprising a hydrophobic thermoplastic polymer such as a polyolefin, which does not absorb water, and a second composition comprising a hydrophilic thermoplastic polymer, for example, polyvinyl alcohol, modified ethyl vinyl alcohol, polyether block polyamide, or the like. The characteristics of the polymers are such that hydrophilic thermoplastic polymer encapsulates the polyethylene layer during extrusion and produces a swellable inkjet receiver layer. Also disclosed are methods for making and a method of printing on such inkjet recording elements.
An inkjet recording element comprising a support having thereon at least one swellable, non-porous ink-receiving layer comprising an immiscible mixture of polymers in the form of a continuous phase and dispersed domains of a discontinuous phase, wherein the continuous phase comprises at least one hydrophilic thermoplastic polymer and the dispersed domains comprise at least one hydrophobic thermoplastic polymer that is essentially neutral and non-crosslinked, wherein the composition of the continuous phase and the composition of the discontinuous phase are both thermally stable at 150° C., and wherein the non-porous ink-receiving layer is formed from a material having a melt strength of 0.5 to 20 centiNewtons, wherein the non-porous ink-receiving layer is the product of melt extrusion, over said support, of said immiscible mixture.
