THERMAL TRANSFER IMAGE RECEIVING SHEET AND PROCESS FOR PRODUCING THERMAL TRANSFER IMAGE RECEIVING SHEET

A thermal transfer image receiving sheet has at least a thermal insulation layer (3) and an image receiving layer (2). The sheet is made of a film laminate obtained by melt-coextruding the thermal insulation layer and the image receiving layer to form a film. The film is then subjected to drawing treatment. The thermal insulation layer includes a thermoplastic resin and a filler and the average particle diameter of the filler, according to the Coulter Counter method is from 1 µm to 4 µm. The following particle size distribution is generated: an amount of the filler which is 1 µm or less in size is 15% or less, and an amount of the filler which is 3 µm or more in size is 15% or less.
