Abstract

Briefly described, embodiments of this disclosure include fusible print media, methods of making fusible print media, and systems for preparing a fused ink-jet image. One exemplary embodiment of the fusible print medium, among others, includes a substrate and an ink-receiving layer disposed on the substrate. The ink-receiving layer includes a plurality of hollow polymer beads having substantially the same diameter.

Claims

1. A fusible print medium, comprising:

a substrate;

an ink-receiving layer disposed on the substrate, wherein the ink-receiving layer includes a plurality of hollow beads having a diameter from about 0.3 to 5μ

meters, a void volume of about 20% to 70%, and a glass transition temperature above 50°

C., wherein the hollow beads have substantially the same diameter, and wherein the hollow beads are at least 70% of the ink receiving layer.

2. The fusible print medium of claim 1, wherein the hollow polymer beads have a diameter from about 0.3 to 2 μ

meters.

3. The fusible print medium of claim 1, wherein the hollow polymer beads have a void volume of about 30 % to 60 %.

4. The fusible print medium of claim 1, wherein the hollow polymer beads have a glass transition temperature above 70°

C.

5. The fusible print medium of claim 1, wherein the hollow polymer beads have a glass transition temperature above 90°

C.

6. The fusible print medium of claim 1, where the hollow polymer bead is derived from the monomers selected from acid monomers, non-ionic monoethylenically unsaturated monomers, polyethylenically unsaturated monomer, and combinations thereof.

7. The fusible print medium of claim 1, further comprising non-hollow polymer beads, wherein non-hollow polymer beads are about 0 to 50 % of the ink-receiving layer.

8. The fusible print medium of claim 7, where the non-hollow beads have a glass transition temperature above 50°

C.

9. The fusible print medium of claim 8 where the non-hollow polymer bead is derived from the monomers selected from acid monomers, non-ionic monoethylenically unsaturated monomers, polyethylenically unsaturated monomer, and combinations thereof.

10. The fusible print medium of claim 1 further comprising a water soluble cationic mordant, wherein the water soluble cationic mordant includes a cationic polymer, wherein the cationic polymer is selected from a polyethyleneimine;

a polyallylamine;

a polyvinylamine;

a dicyandiamide-polyalkylenepolyamine condensate;

a polyalkylenepolyamine-dicyandiamideammonium condensate;

a dicyandiamide-formalin condensate;

an addition polymer of epichiorohydrin-dialkylamine;

a polymer of diallyldimethylammoniumchloride (“

DADMAC”

);

a copolymer of diallyldimethylammoniumchloride-SO₂, polyvinylimidazole, polyvinypyrrolidone;

a copolymer of vinylimidazole, polyamidine, chitosan, cationized starch, polymers of vinylbenzyltrimethylqammoniumchloride, (2-methacryloyloxyethyl)trimethyl-ammoniumchloride, and polymers of dimethylaminoethylmethacrylate;

or a polyvinylalcohol with a pendant quaternary ammonium salt.

11. The fusible print medium of claim 1, further comprising inorganic particles, wherein inorganic particles are 0 to 20 % of the ink-receiving layer.

12. The fusible print medium of claim 11, wherein inorganic particles selected from colloidal silica, fumed silica, precipitated silica, colloidal aluminum oxide, fumed aluminum oxide, boebmite, silica-magnesia, silicic acid, sodium silicate, magnesium silicate, calcium silicate, alumina, alumina hydrate, barium sulfate, calcium sulfate, calcium carbonate, magnesium carbonate, magnesium oxide, kaolin, talc, titania, titanium oxide, zinc oxide, tin oxide, zinc carbonate, pseudo-boebmite, bentonite, hectorite, clay, and mixtures thereof.

13. The fusible print medium of claim 1, wherein the substrate is selected from a paper medium, a photobase medium, a plastic medium, and combinations thereof.
