ABSTRACT:
A multiple-time ink-bearing medium containing a thermally-transferable ink for thermal printing, produced in a process comprising: preparing a resin solution of a water-soluble resin comprising polyvinyl alcohol as a major constituent; preparing a fusible ink material consisting of a mixture which includes a solid fatty acid as a major constituent, a coloring agent, and a fusible agent having a low melting point; finely dispersing the ink material in the resin solution, so as to provide an ink-layer composition; applying the ink-layer composition to one surface of a substrate; and drying the applied ink-layer composition to form an ink layer on the substrate.
