Abstract:
An inkjet recording system comprising:(a) a pigment-based ink for producing an image on the inkjet recording element; and (b) an inkjet recording element comprising at least two distinct layers: (i) an ink-pigment-trapping surface layer, said ink-pigment-trapping surface layer having a thickness less than three microns and relatively thinner than an underlying porous base unit layer, wherein the ratio of the median pore diameter of the ink-pigment-trapping surface layer to the median particle size of the pigment ink is less than 1.5; (ii) a relatively thicker porous base unit layer comprising interconnecting pores throughout the layer, said porous base unit layer having a void volume capable of absorbing essentially all of the applied ink fluids that enter the porous base unit layer, wherein the ratio of the median pore diameter of the porous base unit layer to the median pore diameter of the ink-pigment-trapping surface layer is between 2.0 and 20.
