Abstract
A multiple-use thermal image transfer recording medium is composed of a heat-resistant support, a thermal image transfer layer formed on the heat-resistant support, which thermal image transfer layer is composed of a plurality of thermofusible ink layers overlaid on the heat-resistant support, and a porous resin layer formed on the thermal image transfer layer. The thermal image transfer layer contains a thermofusible ink component containing as the main components a coloring agent and a thermofusible material. The melt viscosity of the thermofusible ink component in each of the thermofusible ink layers is in such a relationship that the melt viscosity increases toward the heat-resistant support.
