- the present invention relates to an inkjet recording element and a printing method using the element. More specifically, the invention relates to a porous media in which the top layer comprises fusible particles of a polymer having functional groups that crosslink with a crosslinking agent external to the particles when the layer is fused.
- inkjet prints prepared by printing onto inkjet recording elements are subject to environmental degradation. They are especially vulnerable to damage resulting from contact with water and atmospheric gases such as ozone.

Some of these methods allow for simultaneous coatings of all three layers, which is preferred from a manufacturing economic perspective.
- lower initial Tg for the fusible polymeric particles can be an advantage for fusing at relatively lower temperatures and/or lower pressures, for example less than about 300°F, instead of 35O 0 F as required for some prior art fusible polymeric particles of a cellulose ester.
- a higher Tg for the top layer of the inkjet element is obtained so that blocking problems are avoided.
- a further advantage of inkjet media that can be made in accordance with the present invention is that, since less heat may be required to fuse the element, the inkjet element can be released from the fusing element when relatively hot without deformation and without lowering gloss or adversely affecting a smooth surface. This facilitates the use of a fuser roller as compared to a belt fuser that may otherwise be needed to provide longer contact so that the inkjet element has sufficient time to cool before release.

- a polymeric particle dispersion comprised of ethyl methacrylate, butyl methacrylate, and hydroxylethyl methacrylate, at the ratio of 85 to 10 to 5 (Polymer Particle Dispersion P-4) was combined with a polyhydroxyalcan polyglycidylether multifunctional polymer (CR-5L from Esprix Technologies) so that the gram/equivalent hydroxy functionality was equal to the gram/equivalent polyhydroxyalcan polyglycidylether functionality and diluted to an 18% aqueous dispersion. This was then coated over Example 1 at a dry laydown of 8.6 g/m (0.8 g/ft 2 ) and dried.
- Each example was then printed with a CANON i550 inkjet printer with KODAK pigmented inks, with a test target comprised of 1 cm 2 color patches, a set of each of the primary and secondary colors. Each patch was printed at 100% density.
- the printed elements were allowed to dry for 1 hour and then were fused in a heated nip at 150°C and 4.2 kg/cm 2 against a sol-gel coated polyimide belt at 76 cm/min.
- a drop of water, coffee, and fruit punch (Hawaiian Punch, contains Red Dye #40 and Blue Dye #1) were placed on the color patches and a white non printed area and allowed to set for 10 minutes and then blotted off.
- Each area where a drop was placed was visually inspected for any stain, water marks, and deformations to the surfaces. If any stain, watermark, or deformation was detected it was a fail grading. If no stain, watermark or deformation was seen it was a pass grade.
- Table 1 summarizes the results: TABLE 1
- a polymeric particle dispersion comprised of ethyl methacrylate and methyl methacrylate, at the ratio of 83 to 17, the mordant divinylbenzene-co-N-vinylbenzyl-N 5 N s N-trimethylammonium chloride, and poly(vinyl alcohol) were diluted at the dry weight ratio of 80/10/10 to make an 18% aqueous dispersion. This was then coated over Example 1 at a dry laydown of 8.6 g/m 2 (0.8 g/sqft) and dried.
- a polymeric particle dispersion comprised of ethyl methacrylate and methacrylic acid, at the ratio of 95 to 5 (Polymer Particle Dispersion P-I) was diluted to make an 18% aqueous solution. This was then coated over Example 2 at a dry laydown of 8.6 g/m 2 (0.8g/sq ft) and dried.
- a polymeric particle dispersion comprised of ethyl methacrylate and methacrylic acid, at the ratio of 95 to 5 (Polymer Particle Dispersion P-I) and an oxazoline functional copolymer (WS-500 from Esprix Technologies, Sarasota, Florida), were combined so that the gram/equivalent acid functionality was equal to the gram/equivalent oxazoline functionality, to make an 18% aqueous solution.
- a polymeric particle dispersion comprised of ethyl methacrylate and methacrylic acid, at the ratio of 95 to 5 (Polymer Particle P-I) was combined with a polyhydroxyalcan polyglycidylether functional polymer (CR-5L from Esprix Technologies) so that the gram/equivalent acid functionality was equal to the gram/equivalent polyhydroxyalcan polyglycidylether functionality, to make an 18% aqueous solution.
- a polymeric particle dispersion comprised of ethyl- methacrylate, butyl methacrylate, and hydroxyethyl methacrylate, at the ratio of 85 to 10 to 5 (Polymer Particle Dispersion P-4) was diluted to an 18% aqueous solution. This was then coated over Example 15 at a dry laydown of 8.6 g/m 2 (0.8g/sq ft) and dried.

This was then coated over Example 15 at a dry laydown of 8.6 g/m 2 (0.8g/sq ft) and dried.
- Each example was then printed with a CANON i550 inkjet printer with CANON dye-based inks, with a test target comprised of 1 cm color patches, a set of each of the primary and secondary colors. Each patch was printed at 100% density.
- the printed elements were allowed to dry for 1 hour and then were fused in a heated nip at 150°C and 4.2 kg/cm 2 against a sol-gel coated polyimide belt at 76 cm/min.
- a drop of water, coffee, and fruit punch (Hawaiian Punch, contains Red Dye #40 and Blue Dye #1) were placed on the color patches and a white non printed area and allowed to set for 10 minutes and then blotted off.
- Each area where a drop was placed was visually inspected for any stain, watermarks, and deformations to the surfaces. If any stain, watermark, or deformation was detected it was assigned a fail grading. If no stain, watermark or deformation was seen it was assigned a pass grade.
