Definitions

• one aspect of the present invention relates to an inkjet recording element capable of absorbing a high flux of applied ink and comprising, in order, over an absorbent support:
• a porous image-receiving upper layer comprising at least 80 percent, by weight of total inorganic particles, of an admixture of fumed alumina particles and aluminum oxyhydroxide particles, wherein the latter particles have a median particle size of from 90 to 150 nm and the former particles have a median secondary particle size of under 200 nm and a primary average particle size of 7 to 40 nm; wherein, based on dry weight coverages, the base layer, optionally divided into one or more sub-layers, is present in an amount of 25 g/m 2 to 60 g/m 2 , the intermediate layer, optionally divided into one or more sub-layers, is present in an amount of 25 g/m 2 to 60 g/m 2 , the upper layer is present in an amount of 1 to 10 g/m 2 and the total dry weight coverage of the base layer, the intermediate layer, and the upper layer is 60 to 130 g/m 2 ; and wherein the imprinted inkjet recording element exhibits a 20- degree gloss
• the base layer comprises particle of silica gel in an amount of at least 5 percent, preferably 10 to 40 percent, more preferably 15 to 35, most preferably 20 to 28 percent by weight based on the total inorganic particles in the base layer.
• binders can also be used such as hydrophobic materials, for example, poly(styrene-co-butadiene), polyurethane latex, polyester latex, poly(n- butyl acrylate), poly(n-butyl methacrylate), poly(2-ethylhexyl acrylate), copolymers of n-butylacrylate and ethylacrylate, copolymers of vinylacetate and n- butylacrylate, and the like.
• a poly(styrene-co-butadiene) latex is preferred.
• Mixtures of hydrophilic and latex binders are useful, and a mixture of PVA with a poly(styrene-co-butadiene) latex is particularly preferred.
• the one or more second materials in the ink-receiving intermediate layer comprise particles of hydrated or unhydrated metallic oxide or semi-metallic oxide.
• the preferred semi-metallic element is silicon.
• the one or more second materials are substantially non-aggregated colloidal particles that comprise silica or hydrated or unhydrated alumina.
• the one or more materials comprise a hydrated alumina that is an aluminum oxyhydroxide material, for example, boehmite and the like.
• the one or more second materials in the ink-receiving intermediate layer comprises from 75 to 100 percent of the inorganic particles in the ink-receiving intermediate layer.
• n is an integer of 0 to 3
• m is a number of 0 to 10, preferably 0 to 5.
• mH ⁇ O represents an aqueous phase which does not participate in the formation of a crystal lattice, but is able to be eliminated. Therefore, m may take a value other than an integer. However, m and n are not 0 at the same time.
• the inkjet recording element can be specially adapted for either pigmented inks or dye-based inks, or designed for both.
• the image-receiving upper layer can function as a pigment-trapping layer.
• both the upper and intermediate layers, or an upper portion thereof, may contain the image, depending on effectiveness of any mordants in the layers.
• pigment-trapping layer is used herein to mean that, in use, preferably at least 75% by weight, more preferably substantially all, of the pigment colorant in the inkjet ink composition used to print an image remains in the pigment-trapping layer.
• mordants include the following: vinylbenzyl trimethyl ammonium chloride/ethylene glycol dimethacrylate; poly(diallyl dimethyl ammonium chloride); poly(2-N,N,N- trimethylammonium)ethyl methacrylate methosulfate; ⁇ oly(3-N,N,N-trimethyl- ammonium)propyl methacrylate chloride; a copolymer of vinylpyrrolidinone and vinyl(N-methylimidazolium chloride; and hydroxyethylcellulose derivatized with 3-N,N,N-trimethylammonium)propyl chloride.
• the cationic mordant is a quaternary ammonium compound.
