Abstract
In a seal-type thermal transfer image-receiving sheet, the total thickness thereof is 250 μm or less, a seal portion has a layered structure in which a pressure-adhesive layer, a seal portion substrate, and a receiving layer are layered in this order from a release portion side. A release portion has a layered structure in which a surface resin layer, a release portion paper substrate, and a back face resin layer are layered in this order from a seal portion side. One or both of the seal portion substrate and the surface resin layer includes a layer made of polyethylene terephthalate is 50 μm or more. The sum of the thickness of the seal portion substrate and the thickness of the surface resin layer is four times or more the thickness of the back face resin layer, and the thickness of the back face resin layer is 20 μm or more.
