Abstract
The present invention provides a heat transfer sheet including a substrate film and a dye and binder-containing dye layer formed thereon, characterized in that the substrate film includes a polyester film and an adhesive layer is formed between the substate film and the dye layer. The adhesive layer is stretched simultaneously with the substrate film, while the adhesive layer remains formed on the substrate film. Such an adhesive layer can be made very thin and is very effective in preventing the dye layer from peeling off. Thus, the invention makes it possible to provide a heat transfer sheet which can impart a high density to the image with an improved heat efficiency.
