  • Thermal image transfer recording medium
    Patent number: 6117562
    Abstract: A thermal image transfer recording sodium includes a support and a thermal image transfer ink layer formed on the support. The thermal image transfer ink layer contains a coloring agent, a resin with a melting point of 120.degree. C. or more and an SP value of 10.5 to 12.5, and a melt viscosity lowering material for lowering the melt viscosity of the resin, with the compatibility of the resin and the malt viscosity lowering material, measured by a transparency measurement method, being 0.20 or less, or with the melt viscosity at 150.degree. C. of the thermal image transfer ink layer being in the range of 1.times.10.sup.2 to 5.times.10.sup.6 poise.
