A fusion ink-type heat transfer sheet for heat-sensitive printing by means of thermal heads, comprises a base film, a substantially smooth antisticking layer formed on the thermal head-contacting surface of said base film, and a hot melt ink layer formed on the opposite surface of said base film. The antisticking layer prevents sticking of the heat transfer sheet to the thermal heads and contains an antistatic agent selected from: cationic antistatic agents having cationic groups selected from a quaternary ammonium salt, a pyridinium salt and primary, secondary or tertiary amino groups; anionic antistatic agents having anionic groups selected from sulfonate and sulfate; amphoteric antistatic agents of amino acid type or aminosulfate type; nonionic antistatic agents of amino-alcohol type glycerin type, or polyethylene glycol type; polymeric antistatic agents obtained by polymerizing the antistatic agents described above; polymerizable antistatic agents of a radiation polymerizable monomer and oligomer having atertiary amino or quaternary ammonium group; and carbon black.
