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