Claims
- 1. A paper comprising:a substrate; and a thin polyester coating over the substrate, wherein the paper enables the generation of toner images with a substantially uniform gloss throughout the images on the coating.
- 2. The paper of claim 1, wherein the substrate comprises a cellulosic material.
- 3. The paper of claim 1, wherein the substrate is a coated reproduction paper.
- 4. The paper of claim 1, wherein the coating has a thickness of from about 1 micron to about 15 microns.
- 5. The paper of claim 4, wherein the images have a gloss value of from about 50 GU to about 100 GU as measured by a 75° Glossmeter.
- 6. The paper of claim 1, further comprising a toner image formed on the coating.
- 7. The paper of claim 6, wherein the toner image is formed by toner embedded in the polyester coating.
- 8. The paper of claim 7, wherein the toner comprises a resin, and the polyester has a lower melt viscosity than the resin at temperatures sufficient to fuse the image.
- 9. The paper of claim 7, wherein the coating has a thickness of from about 1 micron to about 15 microns.
- 10. The paper of claim 1, wherein the substrate is selected from the group consisting of: inkjet paper, offset paper, xerographic paper, natural cellulose, reproduction paper, sized blends of hardwood kraft and softwood kraft, recycled paper, office paper, liquid toner paper, copy paper, sized calcium silicate-clay filled paper, gloss paper and enamel paper.
- 11. The paper of claim 1, wherein an amount of heat required to fuse the toner image to the paper is less than about 175° C.
- 12. A process comprising:forming an image on a polyester coating formed over a substrate; developing the image with toner; and heating the developed image to form an image having a substantially uniform gloss on the substrate.
- 13. The process of claim 12, wherein the coating has a thickness of about 1 micron to about 15 microns.
- 14. The process of claim 13, wherein the image has a gloss value of from about 50 GU to about 100 GU as measured by a 75° Glossmeter.
- 15. The process of claim 12, wherein the toner comprises a resin, and the polyester has a lower melt viscosity than the resin at temperatures sufficient to fuse the image.
- 16. The process of claim 12, comprising applying only heat and pressure to the substrate to sink the toner below a surface of the polyester coating.
- 17. The process of claim 16, wherein the polyester coating has a thickness of from about 1 micron to about 15 microns.
- 18. The process of claim 17, wherein the image has a gloss value of from about 50 GU to about 100 GU as measured by a 75° Glossmeter.
- 19. The process of claim 12, comprising embedding the toner into the heated polyester coating without applying an electric field to the toner.
- 20. The process of claim 12, wherein the substrate is selected from the group consisting of: inkjet paper, offset paper, xerographic paper, natural cellulose, reproduction paper, sized blends of hardwood kraft and softwood kraft, recycled paper, office paper, liquid toner paper, copy paper, sized calcium silicate-clay filled paper, gloss paper and enamel paper.
- 21. The process of claim 12, wherein an amount of heat required to fuse the toner image to the paper is less than about 175° C.
- 22. A paper comprising:a substrate; a polymer coating over the substrate; and a toner embedded in the polymer coating to form an image having a uniform gloss.
- 23. The paper of claim 22, wherein:the substrate comprises a cellulosic material; the polymer coating is formed directly on the substrate; and the paper consists essentially of the substrate and the polymer coating.
- 24. The paper of claim 22, wherein the polymer coating has a thickness of from about 1 micron to about 15 microns.
- 25. The paper of claim 22, the image has a gloss value of from about 50 GU to about 100 GU as measured by a 75° Glossmeter, and the gloss of the image is substantially uniform throughout the image.
- 26. The paper of claim 22, wherein the toner is embedded below an outer surface of the polymer coating.
- 27. The paper of claim 22, wherein:the toner comprises a resin; the polymer has a lower melt viscosity than the resin at temperatures sufficient to fuse the image; and the image has a gloss that is substantially uniform throughout the image.
- 28. The paper of claim 22, wherein the substrate is selected from the group consisting of: inkjet paper, offset paper, xerographic paper, natural cellulose, reproduction paper, sized blends of hardwood kraft and softwood kraft, recycled paper, office paper, liquid toner paper, copy paper, sized calcium silicate-clay filled paper, gloss paper and enamel paper.
- 29. The paper of claim 22, wherein an amount of heat required to fuse the toner image to the paper is less than about 175° C.
