To provide a protective layer transfer sheet that can produce a print having excellent abrasion resistance and an excellent glossiness. A protective layer transfer sheetincluding a transfer layerprovided on one surface of a substrate, wherein the transfer layerhas a single-layer structure composed only of a protective layeror a layered structure in which the protective layeris located nearest to a side of the substrate, and the protective layercontains a styrene resin and a particulate organofluorine compound.

Protective layer transfer sheet

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&#xd7;10N/m-2&#xd7;10N/m. The transfer layer has a release force of 7.5&#xd7;10N/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&#xb0;.

Thermal transfer sheet

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.
