Patent number: 7993807Abstract: A composition, method, and system for recording an image. The system includes a multiphase imaging material in which energy is absorbed by an antenna material. The absorbed energy causes the reaction of an activator and a color-forming material to form a mark. A fixer is employed to retard the fading of the mark.Type: GrantFiled: April 28, 2004Date of Patent: August 9, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Vladek Kasperchik, William Dorogy, Makarand Gore, Marshall Field

Patent number: 7670659Abstract: Substrates, coatings and methods for marking substrates using the coatings. The substrate contains a coating of encapsulated marking materials. Capsules of the encapsulated marking materials are designed to preferentially absorb a predetermined wavelength of light or range of wavelengths of light. The capsules contain color chemistry capable of activation by the predetermined wavelength of light or range of wavelengths of light for the generation of a color response. By utilizing capsules of differing color chemistries, such substrates are capable of multi-color image generation.Type: GrantFiled: April 11, 2005Date of Patent: March 2, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: David M Kwasny, Makarand P. Gore, Andrew L. Van Brocklin, William Dorogy

Patent number: 7433114Abstract: The present invention relates to a microcapsule that can be used to form a rewritable medium for visual displays that are stable in the presence of electric fields having a strength that is typical in the work environment. The microcapsule of the invention comprises charged particles of one or more colors that are suspended in a phase change material that has a melting temperature in the range of between about 30° C. and about 200° C. The microcapsules can be used to form an electrophoretic coating that includes microcapsules of the invention distributed throughout a polymer matrix. The electrophoretic coating can be used to coat a substrate to form a rewritable medium.Type: GrantFiled: January 17, 2007Date of Patent: October 7, 2008Inventors: Andrew L. Van Brocklin, William Dorogy
