PROBLEM TO BE SOLVED: To provide an improved heat-transfer film in order to form an image on a cylinder plate by laser-induction-transferring a polymer from the donor layer of the heat-transfer film. SOLUTION: This heat-transfer film or a heat-transfer tape 1 includes a substrate layer and a donor layer, which is applied on the substrate layer. In this case, the substrate layer comprises at least one polymer material, and the polymer material is equipped with at least following properties such as a mechanical stability under a temperature which is higher than 150 deg.C; and the transmissivity to light of a wavelength from 700 to 1600 nm is lower than 70% Then, the donor layer includes at least the following components such as a substance which can convert the radiation energy of a hit laser beam into a thermal energy, a polymer containing an acid radical and/or its substituted amide group depending on a case, and a wet assisting agent depending on a case. |
