Claims
- 1. An ink-jet printing method, comprising the steps ofA) providing an ink jet printer that is responsive to digital data signals, B) loading said printer with an ink jet recording comprising a support having directly 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, said mixture containing at least about 25% by weight of said water-absorbent polymer, said image-receiving layer being made by dissolving the 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; C) loading said printer with an ink jet ink composition; and D) printing on said ink jet recording element using said ink jet ink in response to said digital data signals.
- 2. The method of claim 1 wherein said water-insoluble polymer is a cellulose ester.
- 3. The method of claim 2 wherein said cellulose ester is cellulose acetate, cellulose acetate butyrate or cellulose acetate propionate.
- 4. The method of claim 1 wherein said water-absorbent polymer is polyvinylpyrrolidone, a vinylpyrrolidone-containing copolymer, an imidazole-containing polymer or copolymer, polyethyloxazoline or an oxazoline-containing copolymer.
- 5. The method of claim 1 wherein said open-pore membrane also contains filler particles.
- 6. The method of claim 5 wherein said filler particles are silicon oxide, aluminum oxide, calcium carbonate, barium sulfate, barium sulfate/zinc sulfide or titanium dioxide.
- 7. The method of claim 1 wherein said open-pore membrane also contains a crosslinking agent.
- 8. The method of claim 1 wherein said open-pore membrane has a thickness of about 2 μm to about 50 μm.
- 9. The method of claim 1 wherein said open-pore membrane also contains a wax or a polyolefin.
- 10. The method of claim 1 wherein said support is paper.
- 11. The method of claim 1 wherein said good solvent is a ketone, ethyl acetate or methylene chloride.
- 12. The method of claim 11 wherein said ketone is acetone or 2-butanone.
- 13. The method of claim 1 wherein said poor solvent is an alcohol, a glycol, a xylene, cyclopentane, cyclohexane or water.
- 14. The method of claim 13 wherein said alcohol is isopropyl alcohol, isobutyl alcohol or 2-methyl-2,4-pentanediol.
- 15. The method of claim 1 wherein said printed ink jet recording element is subjected to heat and/or pressure.
- 16. The method of claim 1 wherein said open-pore membrane contains a plasticizer.
