Patent number: 8652758Abstract: Embodiments of the present invention involve printing members that utilize a particle-fusion imaging mechanism but avoid susceptibility to handling damage. In particular, printing plates in accordance with the invention may utilize two phases, and these may originate, during manufacture, as two particle systems. Both systems are initially dispersed in a single coating applied as a layer, or in multiple coatings applied as adjacent layers, on a substrate. The second particle system exhibits a glass-transition or thermal coalescing temperature well above room temperature and also above the temperature at which the coating is dried. The coalescing temperature of the first particle system is below the drying temperature. As a result, when the coating is dried, the first particle system coalesces and forms a binder that entrains the second particle system, which has not coalesced.Type: GrantFiled: September 16, 2009Date of Patent: February 18, 2014Assignee: Presstek, Inc.Inventors: Frederick R.

Patent number: 5672458Abstract: A process of forming a single color, ablation image having improved abrasion resistance comprising:a) imagewise-heating by means of a laser an ablative recording element comprising a support having thereon an image layer comprising an image dye or pigment dispersed in a polymeric binder, which causes the image layer to ablate imagewise, the image layer having a near infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose the element, the image dye or pigment absorbing in the region of from about 300 to about 700 nm;b) removing the ablated material to obtain an image in the ablative recording element;c) either charging the imaged, ablative recording element to a given polarity or applying a voltage across the surface of the element which is attracted to a conductive surface behind the element;d) applying colorless, charged particles to the element which causes them to be electrostatically attracted to the surface of the image layer; ande) heat-fusing the parType: GrantFiled: July 29, 1996Date of Patent: September 30, 1997Assignee: Eastman Kodak CompanyInventors: Lee William Tutt, Mitchell Stewart Burberry, Vito A.

Patent number: 5629132Abstract: A method for engraving and/or etching comprising the steps of: (a) a process for exposing, to light, a layer of a water-soluble resin composition of a laminated photo-sensitive film which comprises a supporting sheet, a image mask-protection layer peelablly adhered to the supporting sheet and a layer of a water-soluble resin composition having photocrosslinkability to thus cause crosslinking of the exposed area of the resin layer to thereby form a predetermined pattern on the resin layer; (b) a process for dissolving out the non-crosslinked portion of the layer of the water-soluble photo-sensitive resin composition by developing the layer with water to thus from an image-carrying mask which is constituted from the crosslinked area of the photo-sensitive resin composition remaining on the image mask-protection layer; (c) a process for adhering the photo-sensitive laminate film on which the images are formed to the surface of a material to be processed; (d) a process for peeling off the supporting sheet from thType: GrantFiled: February 28, 1996Date of Patent: May 13, 1997Assignee: Aicello Chemical Co., Ltd.Inventors: Tsutomu Suzuki, Ikuo Suzuki

Patent number: 5599648Abstract: Surface reforming of a polymeric article containing a polymerizable compound is effectively performed by polymerizing the polymeric article in contact with a surface reforming medium because the transfer of the material constituting the surface reforming medium to the polymeric article is enhanced by the polymerization. The surface reforming can be performed locally selectively, i.e., imagewise. The remaining un-polymerized part may be subjected to further surface reforming, e.g., by using another type of surface reforming medium or attachment of powder, to provide an enhanced contrast of surface property. Such an enhanced contrast of surface property can be effectively used, e.g., for production of a printing plate.Type: GrantFiled: November 26, 1993Date of Patent: February 4, 1997Assignee: Canon Kabushiki KaishaInventors: Yuji Kondo, Masato Katayama, Akihiro Mouri

Patent number: 5569571Abstract: A process for preparing a black matrix comprising the steps of producing a developed substrate by coating, drying, exposing and developing a photoresist on the inside of a substrate, producing a dried substrate by drying the developed substrate several times, coating a dye on the dried substrate and then drying the board, coating graphite on the dried substrate, and etching the graphite-coated substrate. This method makes it possible to perfectly etch the black matrix dot and increase volatility in fluorescent coating.Type: GrantFiled: June 6, 1995Date of Patent: October 29, 1996Assignee: Samsung Display Devices Co., Ltd.Inventors: Ik-Cheol Lim, Su-Yeon Cho, Seung-Joon Yoo
