The present invention discloses an ink printing method using an image-recording element which provides an image having excellent image quality and superior dry time comprising the steps of: a) providing an ink image-recording element comprising a support having thereon at least one image-receiving layer comprising polymeric particles in a polymeric binder, wherein said polymeric particle is stabilized by a hydrophobically-capped oligomeric acrylamide dispersant; and b) applying liquid ink droplets thereon in an image-wise manner. A further embodiment of the disclosed method comprises the steps of: a) providing an ink printer that is responsive to digital data signals b) loading said printer with an image-recording element comprising a support having thereon at least one image-receiving layer comprising polymeric particles in a polymeric binder, wherein said polymeric particle is stabilized by a hydrophobically-capped oligomeric acrylamide dispersant; c) loading said printer with an ink composition; and d) printing on said image-recording element using said ink composition in response to said digital data signals.

This invention relates to an ink printing method. More particularly, this invention relates to an ink printing method utilizing an ink recording element containing water dispersible polymer particles stabilized with a dispersant.
In a typical inkjet recording or printing system, ink droplets are ejected from a nozzle at high speed towards a recording element or medium to produce an image on the medium. The ink droplets, or recording liquid, generally comprise a recording agent, such as a dye or pigment, and a large amount of solvent. The solvent, or carrier liquid, typically is made up of water, an organic material such as a monohydric alcohol, a polyhydric alcohol or mixtures thereof.
An inkjet recording element typically comprises a support having on at least one surface thereof an ink-receiving or image-forming layer, and includes those intended for reflection viewing, which have an opaque support, and those intended for viewing by transmitted light, which have a transparent support.
3 TABLE 2 Structure of Dispersants 16 17 18 19 20 21
Acrylamide (35.50 g, 0.50 moles) and 1-dodecanethiol (10.10 g, 0.050 moles) were suspended in ethanol (250ml) under nitrogen atmosphere in a 1L three necked round bottomed flask equipped with a reflux condenser. The solution was stirred and degassed with nitrogen for 20 minutes. Stirring was continued and the temperature raised to 70° C. over a period of 20 minutes during which time the reagents dissolved. 2,2′-Azo-bis(2-methylpropionitrile)[AIBN] (1.00 g, 6.10 mmoles) was added to the stirred solution at 70° C. and heating continued for 4 hours under the control of an automated reactor system. During this time a white suspension formed. After cooling, the resulting white precipitate was filtered under suction and dried in vacuo to give a white powder (39.6 g, 87%). Analysis of this product was consistent with the desired product.
Dispersant 2 was synthesized using the same procedure as Dispersant 1 except that a higher mole ratio of acrylamide to dodecanethiol (20:1) was used.
