Abstract
A thermal image transfer recording medium is composed of a support, and a thermofusible ink layer formed on the support, the thermofusible ink layer containing a thermofusible material with a loaded needle penetration of 2 or less at 25.degree. C., and a coloring agent, and having a shearing strength of 8 to 20 gf/cm at 20.degree. C., and an adhesion strength of 1.0 to 2.0 gf/cm with respect to the support. The thermofusible ink layer can be composed of a first ink layer formed thereon, comprising finely-divided particles of a thermofusible material with a loaded needle penetration of 2 or less at 25.degree. C. and an average particle diameter in the range of 0.5 to 3.0 .mu.m, with a voidage of 5 to 30 vol. %, and a second ink layer formed on the first ink layer, composed of a thermofusible material with a loaded needle penetration of 2 or less at 25.degree. C., which may be in the form of finely-divided particles, and a coloring agent.
