However, a method for obtaining an intermediate layer having heat insulating properties by using a foaming agent or a swelling agent usually contained in an electron beam-curable coating is based on the surface of a coating layer after a heat treatment caused by uneven foaming and uneven coating. Due to the unevenness, the highly smooth surface originally obtained by curing with an electron beam or ultraviolet light is remarkably reduced, so that the surface properties are poor even after the image receiving layer is coated, and high gloss and good image quality cannot be obtained.
