  • Patent number: 11794504
    Abstract: To provide a protective layer transfer sheet that can produce a print having excellent abrasion resistance and an excellent glossiness. A protective layer transfer sheet 100 including a transfer layer 10 provided on one surface of a substrate 1, wherein the transfer layer 10 has a single-layer structure composed only of a protective layer 5 or a layered structure in which the protective layer 10 is located nearest to a side of the substrate 1, and the protective layer 5 contains a styrene resin and a particulate organofluorine compound.

  • Patent number: 11104171
    Abstract: A thermal transfer sheet includes a transfer layer on a substrate. The transfer layer has one or more layers. The critical shearing stress of the transfer layer is within the range of 0.9×108 N/m2-2×108 N/m2. The transfer layer has a release force of 7.5×10?2 N/cm or less, while the transfer layer is continuously transferred onto a transfer receiving article by use of a thermal printer under conditions including an applied energy of 0.127 mJ/dot and a conveying speed for the thermal transfer sheet of 84.6 mm/sec. The transfer layer transferred onto the transfer receiving article is released from the thermal transfer sheet at a release angle of 50°.

  • Patent number: 10556457
    Abstract: The present invention provides a thermal transfer sheet including at least a transfer layer and a substrate. The transfer layer includes at least a protective layer adapted to be peelable from the substrate, and the transfer layer has a peel force in a non-heated state of 1 N/m or more and a peel force in a heated state of 10 N/m or less. The thermal transfer sheet exhibits a high level of adhesion therebetween, even when used in a compact printer that causes the thermal transfer sheet to be heated by the heat of a thermal head. The transfer layer exhibits a high level of releasability when being transferred.

  • Publication number: 20180272780
    Abstract: [Problem to be solved] An object of the present invention is to provide a thermal transfer sheet in which a transfer layer and a substrate included therein exhibit a high level of adhesion therebetween even when used in a compact printer that causes the thermal transfer sheet to be heated by the heat of a thermal head, and in which the transfer layer exhibits a high level of releasability when being transferred. [Solution] The thermal transfer sheet according to the present invention is characterized by including at least a substrate and a transfer layer: the transfer layer including at least a protective layer provided so as to be peelable from the substrate; the transfer layer having a peel force in a non-heated state of 1 N/m or more; and the transfer layer having a peel force in a heated state of 10 N/m or less.
