Claims
- 1. An imaged article comprising:
a substrate comprising an ink receptive layer comprising a base polymer selected from the group comprising
a) a urethane acrylic copolymer, b) a blend of at least one polyurethane polymer and at least one acrylic polymer, c) a blend of at least two polyurethane polymers, and mixtures thereof, wherein the ink receptive layer is substantially free of filler; and a non-aqueous ink jetted image on the ink receptive layer.
- 2. The article of claim 1 wherein the ink receptive layer comprises about 10 wt-% to about 50 wt-% of the acrylic polymer.
- 3. The article of claim 1 wherein the ink receptive layer comprises about 25 wt-% to about 35 wt-% of the acrylic polymer.
- 4. The article of claim 1 wherein ink receptive layer comprises about 50 wt-% to about 90 wt-% of the polyurethane polymer.
- 5. The article of claim 1 wherein ink receptive layer comprises about 65 wt-% to about 75 wt-% of the polyurethane polymer.
- 6. The article of claim 2 wherein the composition further comprises and from about 0.2 wt-% to about 4 wt-% of a crosslinking agent.
- 7. The article of claim 1 wherein the urethane acrylic copolymer is further blended with at least one polyurethane polymer, acrylic polymer, or mixture thereof.
- 8. The article of claim 1 wherein the polyurethane polymer has an impart resistance of at least 100 in-lb.
- 9. The article of claim 1 wherein the polyurethane polymer has an impart resistance of at least 150 in-lb.
- 10. The article of claim 1 wherein the polyurethane polymer has an elongation of at least 100%.
- 11. The article of claim 1 wherein the polyurethane polymer has an elongation of at least 150%.
- 12. The article of claim 1 wherein the polyurethane polymer has an elongation of at least 200%.
- 13. The article of claim 1 wherein the polyurethane polymer has a tensile strength and 100% modulus of at least 3000 psi.
- 14. The article of claim 1 wherein the substrate is a polymeric sheet material comprising at least one of an acrylic-containing film, a poly(vinyl chloride)-containing film, a poly(vinyl fluoride)-containing film, a urethane-containing film, a melamine-containing film, a polyvinyl butyral-containing film, a polyolefin-containing film, a polyester-containing film and a polycarbonate-containing film.
- 15. The article of claim 14 wherein the substrate is selected from an acrylic-containing film, a poly(vinyl chloride)-containing film, and a polyolefin-containing film.
- 16. The article of claim 14 wherein the sheet comprises a retroreflective viewing surface.
- 17. The article of claim 1 wherein the ink layer exhibits an improvement in overall image quality in comparison to the same image ink jetted on the same substrate, said substrate being substantially free of an ink receptive coating layer.
- 18. The article of claim 17 wherein the ink layer has a black color density of at least about 1.5.
- 19. The article of claim 17 wherein the ink layer has an ink dot diameter of at least [(2)1/2]/dpi wherein dpi in the print resolution is dots per linear inch.
- 20. The article of claim 1 wherein the ink receptive layer comprises at least one colorant.
- 21. Signage comprising the article of claim 1.
- 22. A commercial graphic film comprising the article of claim 1.
- 23. A method of ink jet printing comprising:
providing a substrate comprising an ink receptor layer derived from an aqueous emulsion or dispersion selected from the group comprising
a) a urethane acrylic copolymer optionally blended with a polyurethane polymer, b) a blend of at least one polyurethane polymer and at least one acrylic polymer, c) a blend of at least two polyurethane polymers, and mixtures thereof, wherein the ink receptive layer is substantially free of filler; and ink jet printing a non-aqueous piezo ink composition on said ink receptive layer.
