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 non-absorbing substrate; C) loading said printer with an ink jet ink composition comprising an aqueous ink jet ink composition comprising: a pigment; a polymer binder containing less than 25% of hydrophilic monomer by weight of the total polymer, which is dispersible but insoluble in aqueous media; at least one surfactant; and a humectant; and D) printing on said ink jet recording element accompanied by a heating step using said ink jet ink composition in response to said digital data signals.
- 2. The method of claim 1 wherein said non-absorbing substrate is a plastic, glass or metal substrate.
- 3. The method of claim 2 wherein said plastic substrate is untreated vinyl.
- 4. The method of claim 1 further comprising an in-situ heating step using a heating means wherein said ink jet recording element is heated to elevated temperature during the printing.
- 5. The method of claim 4 wherein said temperature is between about 30° C. to about 90° C.
- 6. The method of claim 4 wherein said temperature is between 40° C. to about 70° C.
- 7. The method of claim 1 further comprising post-printing heating step wherein said ink jet recording element is heated to elevated temperature after printing using a heating means, wherein said temperature is between about 80° C. to about 120° C.
- 8. The method of claims 4 and 7 wherein said heating means is an irradiation source, a hot air source or an electrical heater.
- 9. The method of claim 8 wherein said irradiation source is an infrared lamp.
- 10. The method of claim 1 wherein the weight ratio of the said pigment to said polymer binder is 1:20 to 20:1.
- 11. The method of claim 1 wherein said pigment comprises up to 10% by weight of the ink composition.
- 12. The method of claim 1 wherein said pigment has an average particle size of less than 0.5 micron.
- 13. The method of claim 1 wherein said surfactant is a siliconated or a fluorinated surfactant or a mixture of both.
- 14. The method of claim 1 wherein said polymer binder is a polyester, an acrylic polymer or a polyurethane.
- 15. The method of claim 1 wherein said polymer binder has a Tg of −50 to 150°.
- 16. The method of claim 1 wherein said polymer binder contains less than 10% by weight of hydrophilic monomer.
- 17. The method of claim 1 where the said pigment is a self-dispersing pigment, an encapsulated pigment or pigment dispersed by a dispersant.
