Abstract

An inkjet printing method, comprising the steps of:

A) providing an ink jet printer that is responsive to digital data signals;

B) loading the printer with ink-receptive elements comprising a support having thereon an image-receiving layer comprising a cationic, water-dispersible, partially quaternized pyridine-containing polymer;

C) loading the printer with an inkjet ink composition comprising water, a humectant, and a water soluble anionic dye; and

D) printing on said image-receiving layer using said ink jet ink in response to said digital data signals.

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 the printer with ink-receptive elements comprising a support having thereon an image-receiving layer comprising a cationic, water-dispersible, partially quaternized pyridine-containing polymer;

C) loading said printer with an ink jet ink composition comprising water, a humectant, and a water-soluble anionic dye; and

D) printing on said image-receiving layer using said ink jet ink in response to said digital data signals.

2. The method of claim 1 wherein said cationic, water-dispersible, partially quaternized pyridine-containing polymer has the formula:

3. The method of claim 2 wherein each R₁ represents H, each A, B and R₂ represents direct links, R₃ is pyridine and R₄ is pyridinium.

4. The method of claim 2 wherein Z is a styrenic monomer, an acrylate ester, a methacrylate ester, an acrylamide, a methacrylamide, a vinylpyrrolidone, a vinyl ester derived from straight chain and branched acids, a vinyl ether, a vinyl nitrile, a vinyl ketone, a halogen-containing monomer or an olefin.

5. The method of claim 2 wherein Z is styrene.

6. The method of claim 2 wherein R₅ is hydroxyethyl, a linear alkyl group having from about 12 to about 18 carbon atoms or benzyl.

7. The method of claim 2 wherein X is chloride.

8. The method of claim 1 wherein said humectant is diethylene glycol, glycerol or diethylene glycol monobutylether.

9. The method of claim 1 wherein said image-receiving layer also contains a binder.

10. The method of claim 9 wherein said binder is a hydrophilic polymer.

11. The method of claim 10 wherein said hydrophilic polymer is gelatin or poly(vinyl alcohol).

12. The method of claim 1 wherein said image-receiving layer contains particulates.

13. The method of claim 12 wherein said particulates are inorganic oxides or organic latex polymers.

14. The method of claim 12 wherein said particulates are barium sulfate, calcium carbonate, clay, silica or alumina.

15. The method of claim 1 wherein said anionic dye comprises about 0.2 to about 5% by weight of said ink jet ink composition.
