  • Publication number: 20230082532
    Abstract: A thermal transfer sheet includes a substrate and a transfer layer, in which the transfer layer after transfer has a reduced peak height (Spk) of 0.6 ?m or more. A method for producing a printed material using a thermal transfer sheet including a particle layer disposed on a substrate and an image-receiving sheet including a thermal protrusion-and/or-recess forming layer and a receiving layer stacked in that order on a second substrate, the receiving layer including an image that has been formed, includes the steps of heating the image-receiving sheet to form a protrusion and/or a recess at the image-receiving sheet, and heating the thermal transfer sheet to transfer the particle layer to at least part of the protrusion of the image-receiving sheet.

    Abstract: An intermediate transfer medium that allows formation of high-density images on a transfer layer while suppressing printing unevenness and provides good foil cutting properties of the transfer layer, a combination of the intermediate transfer medium and a thermal transfer sheet, and a method for forming a print using the intermediate transfer medium. In an intermediate transfer medium having a transfer layer on a substrate, the transfer layer has a single layer structure including only a receiving layer or a layered structure including the receiving layer. When the transfer layer has the layered structure, the receiving layer is located furthest from the substrate among layers constituting the transfer layer. The receiving layer contains a binder resin having a number average molecular weight of 8000-32000 and a release agent. The content of the release agent based on the total mass of the receiving layer is 6% by mass or more.
