Abstract
A thermal transfer image-receiving sheet which has excellent printability such as high printing sensitivity and which is not curled greatly when stored even in a high-temperature and/or high-humidity environment. In the thermal transfer image-receiving sheet in which at least a coloring-material-receptive layer 2 (which will be the face of the image-receiving sheet), a resin layer 3 having minute voids, a support 4, and a backing layer 5 useful for preventing curling are successively laminated in the mentioned order, the backing layer is formed as a laminate of at least two layers 5a and 5b made from different resins. For instance, in the case where a polypropylene film having minute voids is used as the resin layer 3 having minute voids, it is preferable to form the backing layer 5 by the combination use of a polyethylene layer whose behavior in shrinkage is relatively similar to that of the polypropylene film having minute voids, especially a high-density polyethylene layer excellent in water vapor barrier characteristics, and a polypropylene layer excellent in thermal stability, by taking the balance between the total thickness of the layers provided on the surface of the support and the thickness of the backing layer into consideration.
