Claims
- 1. An ink jet recording element comprising a support having thereon an image-receiving layer, said ink jet recording element containing core/shell particles wherein said shell of said particles consists of a metal(oxy)hydroxide complex,
- 2. The recording element of claim 1 wherein said core/shell particles are present in said image-receiving layer.
- 3. The recording element of claim 1 wherein said core/shell particles are present in an overcoat layer.
- 4. The recording element of claim 1 wherein M is a Group IIIA, IIIB, IVA, IVB metal or a lanthanide group metal of the periodic chart.
- 5. The recording element of claim 1 wherein M is tin, titanium, zirconium, aluminum, silica, yttrium, cerium or lanthanum or mixtures thereof.
- 6. The recording element of claim 1 wherein Ap− is an organic anion R—COO−, R—O−, R—SO3−, R—OSO3− or R—O—PO3− where R is an alkyl or aryl group.
- 7. The recording element of claim 1 wherein Ap− is an inorganic anion I−, Cl−, Br−, F−, CO4−, NO3−, CO33− or SO42−.
- 8. The recording element of claim 1 wherein said core comprises silica.
- 9. The recording element of claim 1 wherein said metal(oxy)hydroxide complex is prepared from an aqueous dispersion having a pH between about 3 and 10.
- 10. The recording element of claim 1 wherein M is Zr.
- 11. The recording element of claim 1 wherein n is 4; a, b and c each comprise a rational number as follows: 0≦a<1; 1<b<4; and 1≦pc<4, so that the charge of the M4+ metal ion is balanced.
- 12. The recording element of claim 1 wherein the ratio of the core material to the shell material is at least about 95:5.
- 13. The recording element of claim 1 wherein the ratio of the core material to the shell material is between about 85:15 to about 60:40.
- 14. The recording element of claim 1 wherein Ap− is Cl−, NO3−, CO32−, acetate or propionate.
- 15. The recording element of claim 1 wherein the particle size of said core/shell particle is less than about 1 μm.
- 16. The recording element of claim 1 wherein the particle size of said core/shell particle is less than about 0.1 μm.
- 17. The recording element of claim 1 wherein said support is opaque,
- 18. The recording element of claim 1 wherein said support is transparent.
- 19. The recording element of claim 1 which also includes a base layer located between said image-receiving layer and said support.
- 20. The recording element of claim 1 wherein said image-receiving layer contains a polymeric binder.
