  • Patent number: 6716494
    Abstract: A transfer sheet comprises a support, and a transfer layer separable from the support and receivable an ink, wherein the transfer layer contains a hot-melt adhesive particle. The hot-melt adhesive particle in the transfer sheet comprises a particle having a melting point of more than 80° C. (A) and a particle having a melting point of not more than 80° C. (B), and the particle (A) comprises a hot-melt adhesive particle having an oil absorption of not less than 50 ml/100 g (A1) and a hot-melt adhesive particle having an oil absorption of less than 50 ml/100 g (A2). Further, the transfer layer may comprise a film-formable resin component and a dye fixing agent. The transfer sheet is excellent in stability on delivery of a sheet, so prevents the inside of the printer from staining, and excels in ink-absorption to a degree that the stain transfer does not occur.

  • Patent number: 6623816
    Abstract: An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.
