Patent ID: 6984424

Claim:
A thermally transferable image protective sheet, comprising: a support comprising a biaxially oriented laminated polyester film having a first surface and a second surface; and a thermally transferable resin layer having a single-layer or multilayer structure stacked on the support so as to be separable from the support; wherein: when the thermally transferable resin layer is thermally transferred to a print so as to cover at least an image portion of the print and is subsequently separated from the support to form a thermally transferred resin layer on a surface of the print, the thermally transferred resin layer has a specular glossiness of not less than 60% as measured at an angle of incidence of 20 degrees according to JIS (Japanese Industrial Standards) Z 8741; the first surface of the biaxially oriented laminated polyester film contacts the thermally transferable resin layer and has a first surface roughness Ra of not more than 18 nm; and the second surface of the biaxially oriented laminated polyester film has a second surface roughness Ra larger than the first surface roughness.
