ABSTRACT:
A sublimation thermal image transfer recording method for thermally forming images on an image receiving sheet prepared by forming a dye-receiving layer on a substrate, includes the steps of superimposing a sublimation thermal image transfer recording sheet which has a substrate and at least one recording layer formed thereon containing a sublimable dye, on the image receiving sheet in such a manner that the recording layer of the recording sheet comes into contact with the dye-receiving layer of the image receiving sheet, recording images on the dye-receiving layer of the image receiving sheet by applying thermal energy Ei imagewise to the recording sheet from the substrate side thereof using a thermal head, and subjecting the image-bearing image receiving sheet to heat treatment by applying thermal energy Eb to the image receiving sheet using the thermal head through a sheet member for heat treatment, the thermal energy Eb being smaller than the thermal energy Ei. In the image receiving sheet, an overcoat layer may be formed on the dye-receiving layer, the overcoat layer having a dynamic friction coefficient of less than 0.45 which is measured in accordance with ASTM-01894 and containing a silicone resin and a lubricant.
