PURPOSE:To obtain excellent heat resistance and facilitate the production of the title ink film, by adopting an electronically conjugated aromatic polymer for forming a heat generating layer. CONSTITUTION:An electronically conjugated aromatic polymer is used for forming a heat generating layer. The electronically conjugated aromatic polymer has such a structure that conjugation of electrons can be achieved over the entire part or a major part of the molecular chain thereof, and may be, for example, polypyrrole, polythiophene, polyfuran, poly-p-phenylene, poly-p- phenylenevinylene or a derivative thereof obtained by polymerization of pyrrole, thiophene, furan, benzene or a derivative thereof. The electronically conjugated aromatic polymer has extremely favorable heat resistance, and enables printing at high temperatures, which makes it possible to lower the viscosity of an ink or raise the sublimation rate at the time of transferring, and therefore to enhance the printing speed. In addition, a base supporting the polymer can be inserted between a conductor layer and an ink layer, whereby the production process is facilitated.
