Claims
- 1. An ink jet recording material comprising a subbed polyester support, and an ink receiver layer containing a cationic compound, characterized in that between said support and said ink receiver layer there is an additional adhesion promoting layer present comprising a binder and a cationically modified silica.
- 2. An ink jet recording material according to claim 1 wherein said silica is cationically modified by subjecting it to a surface treatment with a cationic inorganic compound.
- 3. An ink jet recording element according to claim 2 wherein said cationic inorganic compound, by which said silica is modified, is pseudo-boehmite.
- 4. An ink jet recording element according to claim 1 wherein said silica is cationically modified by subjecting it to a surface treatment with an organic compound having both an amino group or quaternary group thereof or a quaternary phosphonium group, and a functional group having reactivity to a silanol group on the surface of silica.
- 5. An ink jet recording element according to claim 1 wherein said silica is cationically modified by polymerization of a cationic or amino functional monomer in the presence of silica.
- 6. An ink jet recording element according to claim 1 wherein the binder in said adhesion promoting layer is cationic polyvinyl alcohol.
- 7. An ink jet recording element according to claim 1 wherein the cationically modified silica/binder ratio in said adhesion promoting layer is between 1:4 and 10:1.
- 8. An ink jet recording element according to claim 1 wherein the thickness of said adhesion promoting layer is comprised between 1 and 6 g/m2.
- 9. An ink jet recording element according to claim 1 wherein the cationic compound present in the ink receiver layer is a cationic inorganic pigment.
- 10. An ink jet recording element according to claim 9 wherein said cationic pigment is chosen from the group consisting of aluminum oxides, aluminum hydroxides, alumina hydrates, aluminum silicates, and cationically modified silicas.
- 11. An ink jet recording element according to claim 10 wherein said cationic pigment is boehmite.
- 12. An ink jet recording element according to claim 1 wherein the cationic compound present in the ink receiver layer is a cationic polymer.
- 13. An ink jet recording element according to claim 12 wherein said cationic polymer is cationic polyvinyl alcohol.
- 14. An ink jet recording element according to claim 12 wherein said cationic polymer is poly(diallyldimethylammonium chloride).
