Abstract:
A thermal transfer protective sheet, a print and a print with a window member are provided. The thermal transfer protective sheet 10 including a release layer 2 and a topcoat layer 3 having adhesiveness to an object to be transferred, which are stacked in this order on a base material 1, wherein the release layer 2 and the topcoat layer 3 are cold-peeled and transferred to the surface of the object to be transferred by the fusion thermal transfer recording method. The release layer 2 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.
