Further, the release layer may consist of two sub-release layers which are successively overlaid on the support, with one of the sub-release layers containing the thermofusible wax component, and the other sub-release layer containing the unvulcanized rubber and the thermofusible wax component. The thermosensitive image transfer recording medium may further include a mat layer containing a pigment and a binder agent between the support and the release layer, and if necessary an overcoat layer on the thermofusible ink layer, which contains a thermofusible wax component or a mixture of a thermofusible wax component and a thermofusible resin component.
