Publication number: 20140161996Abstract: A method of imaging acrylic glass is presented. An image is formed on a transfer sheet or medium, and is heat transferred to the acrylic glass substrate on which the image is to permanently appear. An opaque pass-through coating is applied to one surface of the clear or transparent acrylic glass article. Heat activatable dye forms the image, and the heat activatable dye, when heat activated in close relationship to the opaque pass-through coating, passes through the opaque pass-through coating to the acrylic glass substrate. The image reflects light through the acrylic glass and is visible through the material and from the side opposite the opaque coating. The opaque pass-through coating layer permanently bonds to the acrylic glass surface.Type: ApplicationFiled: July 25, 2013Publication date: June 12, 2014Inventors: Ming Xu, Zhenrong Guo, Sukun Zhang, Paul Hirst

Patent number: 8628185Abstract: A reactive ink for printing. A reagent in the ink reacts with a second reagent. A resultant product of the reaction of said first reagent with said second reagent is a polymeric material that is present on the substrate. A heat activated colorant or colorants, such as a sublimation dyes, are applied to the substrate. The heat activated dye has an affinity for the polymeric material, and the heat activated dye binds to the polymeric material upon heat activation of said heat activated dye.Type: GrantFiled: February 26, 2013Date of Patent: January 14, 2014Assignee: Sawgrass Technologies, Inc.Inventors: Nathan Hale, Ming Xu, Kimberlee Thompson, Sukun Zhang

Patent number: 8398224Abstract: Reactive inks and methods of generating an image on a substrate using both reactive and heat activated inks are presented. An image is printed on a substrate, without reacting the reagents in the ink. Subsequently, the reagents are reacted to fix the image to a substrate, with substantial permanency and fastness. Sublimation or similar heat activated dyes are printed are also printed on the substrate. The sublimation or similar heat activated dyes are activated, and have an affinity for polymer that is applied to the substrate.Type: GrantFiled: December 16, 2009Date of Patent: March 19, 2013Assignee: Sawgrass Technologies, Inc.Inventors: Nathan Hale, Ming Xu, Kimberlee Thompson, Sukun Zhang

Patent number: 8029883Abstract: A transfer medium is provided for receiving images formed on the medium by inks or toners comprising thermally diffusible colorants, including disperse dye and sublimation dye, and methods of using the medium to present images on substrates. The medium provides an opaque layer that allows transfer of the image from the medium to a substrate, and provides a background for the image when the image is transferred to a dark colored substrate, so that the dark colored substrate does not obscure the image.Type: GrantFiled: November 5, 2009Date of Patent: October 4, 2011Inventors: Ming Xu, Zhenrong Guo, Sukun Zhang

Publication number: 20110111188Abstract: A method of imaging thermoplastics, such as acrylic glass, is presented. An image is formed on a transfer sheet or medium, and is heat transferred to the acrylic glass substrate on which the image is to permanently appear. An opaque pass-through coating is applied to one surface of the clear or transparent acrylic glass article. Heat activatable dye forms the image, and the heat activatable dye, when heat activated in close relationship to the opaque pass-through coating, passes through the opaque pass-through coating to the thermoplastic substrate. The image reflects light through the thermoplastic material and is visible through the material and from the side opposite the opaque coating. The opaque pass-through coating layer permanently bonds to the acrylic glass surface.Type: ApplicationFiled: November 11, 2010Publication date: May 12, 2011Inventors: Ming Xu, Zhenrong Guo, Sukun Zhang, Paul Hirst

Patent number: 6887640Abstract: A process for printing images by means of an electrographic or electrostatic device using a toner that is cured by multiple applications of energy. The toner has energy-activated reactive components such as radiation-curable sites and reactive functional groups. An image is formed on a substrate by the toner without materially activating the reactive components. The reactive components are subsequently activated by applying a first energy source to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate. A second energy source is applied simultaneously with, or subsequently to, the first energy source, to promote cohesive strength of the image by cross-linking within the toner particles that form the image. The resulting image is permanently bonded to the substrate, yielding substantially enhanced image durability and fastnesses.Type: GrantFiled: February 28, 2002Date of Patent: May 3, 2005Inventors: Sukun Zhang, Rebecca Silveston, Ming Xu
