THERMAL TRANSFER IMAGE-RECEIVING SHEET AND METHOD FOR PRODUCING THE SAME

It is an object of the present invention to provide a high performance and highly productive thermal transfer image-receiving sheet which solves drawbacks of the prior art, i.e., drawbacks such as the deterioration in sensitivity in using a pulp paper such as a coated paper as a substrate, and the reduction in productivity and the increase in cost in using a laminated and bonded sheet of a void-containing biaxially stretched film and a core material, is inexpensive, and can attain high-density and high-resolution images having no density irregularity and dot missing. A method of producing a thermal transfer image-receiving sheet in which at least an insulating layer 15 and an image-receiving layer 8 are formed in this order on a substrate 11, comprising the steps of melt-coextruding the insulating layer including a thermoplastic resin (A) and a resin or filler which is not compatible with the thermoplastic resin (A) and the receiving layer including a thermoplastic resin (B) to form a film, and then stretching this melt-coextruded film to form a layered body of a film, and then laminating the layered body on a substrate with the insulating layer side of the layered body faced with the substrate, wherein said image-receiving layer or a release layer provided on said image-receiving layer side of said layered body contains modified silicone oil and the void fraction of the insulating layer is 15 to 65%.
