Abstract: An ink jet recording element comprising a support having thereon an image-receiving layer, the ink jet recording element containing finely divided particulate material and a metal(oxy)hydroxide complex, Mn+(O)a(OH)b(Ap−)c.xH2O, wherein M is at least one metal ion; n is 3 or 4; A is an organic or inorganic ion; p is 1, 2 or 3; and x is equal to or greater than 0; with the proviso that when n is 3, then a, b and c each comprise a rational number as follows: 0≦a<1.5; 0<b<3; and 0≦pc<3, so that the charge of the M3+ metal ion is balanced; and when n is 4, then a, b and c each comprise a rational number as follows: 0≦a<2; 0<b<4; and 0≦pc<4, so that the charge of the M4+ metal ion is balanced.

Abstract: An ink jet recording element comprising a support having thereon an image-receptive layer capable of accepting an ink jet image, the layer comprising an open-pore membrane of a mixture of a water-insoluble polymer, a water-absorbent polymer and a mordant, the mixture containing at least about 25% by weight of the water-absorbent polymer, at least about 7% by weight of the mordant, and the balance being the water-insoluble polymer, the mordant comprising a polymer or copolymer containing a quaternized nitrogen moiety.

Abstract: An ink jet recording element comprising a support having thereon an image-receptive layer capable of accepting an ink jet image comprising an open-pore membrane of a mixture of a water-insoluble polymer and a water-absorbent polymer, the mixture containing at least about 25% by weight of the water-absorbent polymer, the image-receiving layer being made by dissolving the mixture of polymers in a solvent mixture, the solvent mixture comprising at least one solvent which is a good solvent for the water-insoluble polymer and at least one poor solvent for the water-insoluble polymer, the poor solvent having a higher boiling point than the good solvent, coating the dissolved mixture on the support, and then drying to remove approximately all of the solvents to obtain the open-pore membrane.

Abstract: An ink jet printing method, comprising the steps of: A) providing an ink jet printer that is responsive to digital data signals; B) loading the printer with an ink jet recording element comprising a support having thereon an image-receptive layer capable of accepting an ink jet image, the layer comprising an open-pore membrane of a mixture of a water-insoluble polymer, a water-absorbent polymer and a mordant, the mixture containing at least about 25% by weight of the water-absorbent polymer, at least about 7% by weight of the mordant, and the balance being the water-insoluble polymer, the mordant comprising a polymer or copolymer containing a quatemized nitrogen moiety; C) loading the printer with an ink jet ink composition; and D) printing on the ink jet recording element using the ink jet ink in response to the digital data signals.
