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 comprising a support having thereon an image-receiving layer, said ink jet recording element containing a metal hydroxide salt, (M2+)(OH)a(Ap−)b.xH2O; wherein:
M2+ is at least one metal ion having a 2+ oxidation state; A is an organic or inorganic anion; p is 1 or 2; and x is equal to or greater than 0; and a and b comprise rational numbers as follows: 0<a<2 and 0<b<2 so that the charge of M2+ 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 metal hydroxide salt is present in said image-receiving layer.
- 3. The method of claim 1 wherein M2+ is zinc, magnesium, barium, calcium, tin, nickel, cobalt or copper.
- 4. The method of claim 1 wherein said metal hydroxide salts is a zinc hydroxy double salt.
- 5. The method of claim 3 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.
- 6. The method of claim 1 wherein Ap− is an inorganic anion I−, Cl−, Br−, F−, ClO4−, NO3−, CO32− or SO42−.
- 7. The method of claim 1 wherein said metal hydroxide salt is in particulate form.
- 8. The method of claim 1 wherein said metal hydroxide salt is prepared from an aqueous dispersion having a pH between about 3 and 10.
- 9. The method of claim 1 wherein M is Zn.
- 10. The method of claim 9 wherein Ap− is Cl, NO3, acetate, propionate or an organosulfonate.
- 11. The method of claim 10 wherein a is between and including 1.4 and 1.6, and b is between and including 0.4 and 0.6.
- 12. The method of claim 1 wherein the particle size of said metal hydroxide salt is less than about 5 μm.
- 13. The method of claim 1 wherein the particle size of said metal hydroxide salt is less than about 1 μm.
- 14. The method of claim 1 wherein said support is opaque,
- 15. The method of claim 1 wherein said support is transparent.
- 16. The method of claim 1 which also includes a base layer located between said image-receiving layer and said support.
- 17. The method of claim 1 wherein said image-receiving layer contains a polymeric binder.
