PROBLEM TO BE SOLVED: To provide a heat transfer sheet in which retention force of a dye in a dye layer is improved without decreasing transfer sensitivity when heat- sensitive transfer is performed and which has excellent stability with time. SOLUTION: The heat transfer sheet consisting of a dye layer comprising a sublimating dye and a binder resin formed on a base material film is provided and the heat transfer sheet is characterized by the binder resin in which an isocyanate-modified polyvinyl acetoacetal or an isocyanate-modified polyvinyl butyral with a specified structure is a main ingredient. |
