PURPOSE:To eliminate scummings and obtain a sharp printing, by a method wherein a recording medium is formed by laminating a hot-melt layer containing the ester of a branched satd. primary alcohol etc. and a fatty acid etc. and a heat-softening coloring layer successively on a heat-resistant substrate. CONSTITUTION:On a heat-resistant substrate such as a good-heat resistance plastic film, cellophane, and condenser paper, a hot-melt layer containing an oil mainly composed of a branched satd. primary alcohol and/or the ester of the aforesaid alcohol and a fatty acid or a hydroxy-fatty acid. Furthermore, on the hot-melt layer, a thermal transfer ink layer made of a heat-softening coloring layer which exhibits tackiness due to heat and has no possibility of melting to become a low-viscosity liquid is laminated; in this manner, a transfer- type thermal recording medium is obtained. As the branched satd. primary alcohol, an oil shown by formula I (m, n each is an integer which satisfies 7 < m + n < 28) is preferably used. |
