Abstract:
1. A inkjet recording element capable of absorbing a high flux of applied ink and comprising, in order, over an absorbent support: (a) a porous base layer comprising greater than 50 percent, by weight of the layer, of particles of one or more first materials having a median particle size of at least 0.4 micrometers, which base layer, optionally divided into sub-layers, is present in an amount of 25 g/m (b) a porous ink-receiving intermediate layer comprising greater than 50 percent, by weight of the layer, of particles of one or more second materials having a median particle size less than 300 nm, wherein the intermediate layer, optionally divided into sub-layers, is present in an amount 2 of 25 g/m (c) a porous image-receiving upper layer comprising greater than 50 percent, by weight of the layer, of a mixture of materials having a median particle size including (i) non-aggregated colloidal particles of one or more materials having a median particle size of under 200 nm, at least 10 percent smaller than the particles of the one or more second materials, and (ii) aggregated colloidal particles of one or more materials having a median secondary particle size up to 250 nm and a primary particle size of 7 to 40 nm, which porous image-receiving layer, optionally divided into sub-layers, is present in an amount of 1 to 10 g/m wherein the total dry weight coverage of the base layer, the intermediate layer, and the upper layer is 61 to 130 g/m and wherein the unprinted inkjet recording element exhibits a 20-degree gloss of at least 15 Gardner gloss units.
