Claims
- 1. An ink jet printing method comprising the steps of:
A) providing an ink jet printer that is responsive to digital data signals; B) loading said printer with an ink jet recording element containing core/shell particles wherein said shell of said particles consists of a metal(oxy)hydroxide Mn+(O)a(OH)b(Ap−)c.xH2O, wherein M is at least one metal ion; n is 3 or 4; A is an organic or inorganic ion; p is 1, 2 or 3; and x is equal to or greater than 0; with the proviso that when n is 3, then a, b and c each comprise a rational number as follows: 0≦a<1.5; 0<b<3; and 0≦pc<3, so that the charge of the M3+ metal ion is balanced; and when n is 4, then a, b and c each comprise a rational number as follows: 0≦a<2; 0<b<4; and 0≦pc<4, so that the charge of the M4+ metal ion is balanced; C) loading said printer with an ink jet ink composition; and D) printing on said ink jet recording element using said ink jet ink composition in response to said digital data signals.
- 2. The method of claim 1 wherein said core/shell particles are present in said image-receiving layers.
- 3. The method of claim 1 wherein said core/shell particles are present in an overcoat layer.
- 4. The method of claim 1 wherein M is a Group IIIA, IIIB, IVA, IVB metal or a lanthanide group metal of the periodic chart.
- 5. The method of claim 1 wherein M is tin, titanium, zirconium, aluminum, silica, yttrium, cerium or lanthanum or mixtures thereof.
- 6. The method of claim 1 wherein Ap− is present and 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 method of claim 1 wherein Ap− is present and is an inorganic anion I, Cl−, Br−, F−, ClO4−, NO3−, CO32− or SO42−.
- 8. The method of claim 1 wherein said core comprises silica.
- 9. The method 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 method of claim 1 wherein M is Zr.
- 11. The method 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 method of claim 1 wherein a is 0, n is 4, and b+pc is 4.
- 13. The method of claim 1 wherein a is 0, n is 3, and b+pc is 3.
- 14. The method of claim 9 wherein Ap− is present and is Cl−, NO3−, CO32−, acetate or propionate.
- 15. The method of claim 1 wherein the particle size of said core/shell particle is less than about 1 μm.
- 16. The method of claim 1 wherein the particle size of said core/shell particle is less than about 0.1 μm.
- 17. The method of claim 1 wherein said support is opaque.
- 18. The method of claim 1 wherein said support is transparent.
- 19. The method of claim 1 which also includes a base layer located between said image-receiving layer and said support.
- 20. An ink jet printing method comprising the steps of:
A) providing an ink jet printer that is responsive to digital data signals; B) loading said printer with an ink jet recording element containing core/shell particles wherein said shell of said particles consists of a metal hydroxide complex, Mn+(OH)b(Ap−)c.xH2O, wherein M is at least one metal ion; n is 3 or 4; A is an organic or inorganic ion; p is 1, 2 or 3; and x is equal to or greater than 0; with the proviso that when n is 3, then a, b and c each comprise a rational number as follows: 0<b<3; and 0≦pc<3, so that the charge of the M3+ metal ion is balanced; and when n is 4, then b+pc is 4, and b and c each comprise a rational number as follows: 0<b<4; and 0≦pc<4, so that the charge of the M4+ metal ion is balanced; C) loading said printer with an ink jet ink composition; and D) printing on said ink jet recording element using said ink jet ink composition in response to said digital data signals.
