Patent number: 7128955Abstract: A thermal transfer recording medium 1 according to the present invention is to obtain a reliable printed matter with no space between picture information and a protective film thereof and has a melting type transfer portion 161 including a melting type primer layer 181 whose main component is styrene vinyl acetate copolymer and a melting type ink layer 171. Since styrene vinyl acetate copolymer softens or melts by heating to lose mechanical strength thereof, the melting type transfer portion 161 is transferred with ease from a base sheet 11 by heating to form a printing layer 47. On the surface of the printing layer 47, a residual resin 49 formed of material of the melting type primer layer 181 is exposed; however, since styrene vinyl acetate copolymer sticks well to a thermoplastic resin existing on the surface portion of a protective portion 251, there is no space generated between the protective portion 251 and the printing layer 47.Type: GrantFiled: March 5, 2003Date of Patent: October 31, 2006Assignees: Sony Corporation, Sony Chemical & Information Device CorporationInventor: Takuya Monju

Patent number: 6869650Abstract: The present invention is drawn to the thermal transfer overcoating of images printed on porous media, and methods of overcoating images printed on porous media. Upon use of the systems and methods of the present invention, a thermally coated print is generated that can comprise a porous media substrate having printed thereon a digitally produced image. The digitally produced image and the porous media substrate is thermally coated by an adhesive protective layer, wherein the adhesive protective layer has a tangent d that is greater than 1 and melt viscosity less than 1×105 Pa.·sec. as applied above its phase transition temperature. Thus, the voids in the porous media substrate can be substantially filled, and further, substantially no tags remain on the print.Type: GrantFiled: June 11, 2002Date of Patent: March 22, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Eric L Burch, Vladek P Kasperchik, Shilin Guo, David J Arcaro, Gary E Hanson, Maximo Gayoso, Richard J McManus, Dan M Weeks
