A thermal transfer protective sheet, a print, and a print with a window member are provided. The thermal transfer protective sheet includes a release layer and a topcoat layer having adhesiveness to an object to be transferred, which are stacked in this order on a base material, wherein the release layer and the topcoat layer are cold-peeled and transferred to the surface of the object to be transferred by the fusion thermal transfer recording method. The release layer comprises a first resin consisting of a thermoplastic resin and a second resin incompatible with the first resin in a mixed state. The first resin is an acrylic resin, and the second resin is a thermoplastic resin having a glass transition point of 50° C. or less. The mixing ratio of the first resin to the second resin is 80:20 or more and 99:1 or less in a weight ratio. In the release layer, the second resin exists as a particulate phase in the first resin, thereby inhibiting fusion between the base material and the release layer even if cooling is insufficient during peeling.
A thermal transfer protective sheet comprising:
A print comprising:
A print with a window member comprising an object to be transferred, an ink layer formed on the surface of the object to be transferred, an adhesive topcoat layer provided on at least the surface of the ink layer, a release layer provided on the topcoat layer, and a window member provided on the surface of the release layer,
