Claims
- 1. An ink jet recording material comprising a transparent polyester support, and on the front side of said support a layer pack (A) comprising a latex subbing layer, a gelatin subbing layer, and at least two ink-receiving layers comprising a polyvinyl alcohol binder whereby the top layer of said ink-receiving layers further comprises a cationic mordant and a spacing agent, and on the back side of said support a double layer pack (B) comprising, in order, a latex subbing layer containing an electronically conductive polymer, and a second backing layer containing a crosslinked hydrophilic binder and a spacing agent.
- 2. An ink jet recording material according to claim 1 wherein said cationic mordant is a cationic polyurethane latex.
- 3. An ink jet recording material according to claim 1 wherein said cationic mordant is a poly(diallyldialkylammonium chloride).
- 4. An ink jet recording material according to claim 1 wherein said spacing agent in said top ink-recording layer on the front side, and/or in said second backing layer is copoly(methylmethacrylate-stearylmethacrylate 98%/2%), stabilized by poly(styrene-maleic acid, sodium salt).
- 5. An ink jet recording material according to claim 1 wherein said layer pack (A) on the front side comprises three layers.
- 6. An ink jet recording material according to claim 1 wherein said electronically conductive polymer in said latex subbing layer on the back side is a polythiophene/polyanion complex.
- 7. An ink jet recording material according to claim 6 wherein said polythiophene is poly(3,4-ethylenedioxythiophene).
- 8. An ink jet recording material according to claim 6 wherein said polyanion is polystyrene sulphonate.
- 9. An ink jet recording material according to claim 1 wherein said hydrophilic binder of said second backing layer is gelatin.
- 10. An ink jet recording material according to claim 9 wherein said gelatin is crosslinked by means of a vinylsulfone hardener.
- 11. An ink jet recording material comprising a transparent polyester support, and on the front side of said support a layer pack (A) comprising a latex subbing layer, a gelatin subbing layer, and at least two ink-receiving layers comprising a polyvinyl alcohol binder whereby the top layer of said ink-receiving layers further comprises a cationic mordant and a spacing agent, and on the back side of said support a double layer pack (B′) comprising, in order, a latex subbing layer and a second backing layer containing an electronically conductive polymer and a spacing agent.
- 12. An ink jet recording material according to claim 11 wherein said cationic mordant is a cationic polyurethane latex.
- 13. An ink jet recording material according to claim 11 wherein said cationic mordant is a poly(diallyldialkylammonium chloride).
- 14. An ink jet recording material according to claim 11 wherein said spacing agent in said top ink-recording layer on the front side, and/or in said second backing layer is copoly(methylmethacrylate-stearylmethacrylate 98%/2%), stabilized by poly(styrene-maleic acid, sodium salt).
- 15. An ink jet recording material according to claim 11 wherein said layer pack (A) on the front side comprises three layers.
- 16. An ink jet recording material according to claim 11 wherein said electronically conductive polymer in said second backing layer is a polythiophene/polyanion complex.
- 17. An ink jet recording material according to claim 16 wherein said polythiophene is poly(3,4-ethylenedioxythiophene).
- 18. An ink jet recording material according to claim 16 wherein said polyanion is polystyrene sulphonate.
- 19. A method for the preparation of a lithographic printing plate involving the following steps, in order,:(1) preparing an ink jet recording material as defined by claim 1, (2) jetting information-wise droplets of a UV-absorbing ink onto the front surface of said ink jet recording material by means of an ink jet printer thus forming a printed image, (3) exposing overall by actinic light a lithographic printing plate precursor through a mask consisting of the printed image formed by steps (1) and (2), (4) developing the exposed lithographic printing plate precursor into a lithographic printing plate.
- 20. A method according to claim 19 wherein said ink is an aqueous ink containing carbon black.
- 21. A method according to claim 19 wherein said ink is an aqueous ink containing a mixture of dyes adding up to black.
- 22. A method for the preparation of a silk screen printing element involving the following steps, in order,:(1) preparing an ink jet recording material as defined by claim 1, (2) jetting information-wise droplets of an ink onto the front surface of said ink jet recording material by means of an ink jet printer thus forming a printed image, (3) exposing overall by actinic light a silk screen through a mask consisting of the printed image formed by steps (1) and (2), (4) developing the exposed silk screen into a silk screen printing element.
- 23. A method according to claim 22 wherein said ink is an aqueous ink containing carbon black.
- 24. A method according to claim 22 wherein said ink is an aqueous ink containing a mixture of dyes adding up to black.
