  • Patent number: 6465393
    Abstract: A thermal transfer sheet of the present invention is used in order to previously form an image in a receptor layer of the intermediate transfer recording medium before the receptor layer is re-transferred to a transfer receiving material, and it comprises: a substrate film, a peelable layer disposed on the substrate film, and a heat fusible black ink layer disposed on the substrate film via the peelable layer, wherein the peelable layer is formed of a material having peelable property to the substrate film while having adhesive property to the transfer receiving material so that the peelable layer is transferred to the receptor layer of the intermediate transfer recording medium together with the heat fusible black ink layer when the image is formed in the receptor layer so as to constitute an uppermost layer of the receptor layer, the uppermost layer being adhesive to the transfer receiving material.

  • Patent number: 6129966
    Abstract: A lamination-type image receiving sheet having excellent storage stability is provided. The image receiving sheet comprises: an image receiving substrate; and a pressure-sensitive adhesive layer and a release resin film provided in that order on the image receiving substrate on its side opposite to the image receiving surface. The image receiving substrate is in the form of a resin film. The surface roughness (Ra) of the release resin film on its side opposite to the pressure-sensitive adhesive layer is in the range of 0.2 to 0.8 .mu.m.

  • Patent number: 6001771
    Abstract: A receptor layer transfer sheet, as intermediate transfer medium film, provided with a receptor layer to be transferred on a surface of a transfer-receiving material with an image preliminarily formed on the receptor layer comprises: a substrate film; an ionizing radiation (electron beam) hardening resin layer formed on the substrate film to be separable; and a receptor layer formed on the ionizing radiation hardening resin layer. The receptor layer is transferred together with the ionizing radiation hardening resin layer to the transfer-receiving material at a transferring process. A card-shaped printed product can be manufactured by using the receptor layer transfer sheet of the character mentioned above, in which an image is formed, through a sublimation thermal transfer process, on a receptor layer of a receptor layer transfer sheet. The receptor layer is transferred together with the ionizing radiation hardening resin layer on a card-shaped transfer-receiving material through a thermal transfer process.
