Patent number: 8304076Abstract: Various embodiments provide a plurality of particles and a reimageable medium including the plurality of particles. The plurality of particles can include a binder; a photochromic material; and a light absorbing material. The photochromic material is capable of reversibly converting among a less colored form and a more colored form in response to a predetermined wavelength scope, where light absorption by the light absorbing material is less than about 50% of light absorption by the less colored form of the photochromic material.Type: GrantFiled: October 3, 2008Date of Patent: November 6, 2012Assignee: Xerox CorporationInventors: Tyler Norsten, Daryl W Vanbesien, Gabriel Iftime, Kentaro Morimitsu, Peter M Kazmaier, Gordon Sisler

Patent number: 8216765Abstract: The present disclosure provides a reusable and reimageable medium including a substrate coated with a photochromic polymer. The photochromic polymer has a glass transition temperature ranging from 30° C. to 150° C., such as from about 30° C. to about 100° C., and the coated substrate converts to a colored state when both UV light and temperatures ranging from 30° C. up to 100° C. are applied to the coated substrate. The present disclosure also provides a method for producing and using the reusable and reimageable medium.Type: GrantFiled: March 9, 2009Date of Patent: July 10, 2012Assignee: Xerox CorporationInventors: Kentaro Morimitsu, Tyler Norsten, Gabriel Iftime, Peter M. Kazmaier, Guerino Sacripante

Patent number: 7811741Abstract: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.Type: GrantFiled: February 24, 2009Date of Patent: October 12, 2010Assignee: Xerox CorporationInventors: Peter M. Kazmaier, Eric Shrader, Kentaro Morimitsu, Tyler Norsten, Gabriel Iftime, Fazilia Seker, Naveen Chopra

Publication number: 20060270822Abstract: Fluorinated comb co-polymers have a main chain including a semi-rigid hydrophobic fluorinated poly(ether) backbone and comb segments in the form of flexible and monodisperse side chains that are more hydrophilic than the backbone. The side chains may be hydrophilic polymeric chains obtained from “living-type” polymerization, for example polymethacrylates, polyethylene oxides, polystyrenes. Hydrophilic functionality, for example, ionic groups may be selectively introduced onto the side chain post polymerization. The side chain may be sulfonated ?-methyl polystyrene. Such polymers are useful in proton exchange membranes.Type: ApplicationFiled: May 26, 2006Publication date: November 30, 2006Inventors: Tyler Norsten, Jianfu Ding, Michael Guiver, Yinghua Qi
