Abstract: The present invention relates to image-formation on any selected kind of objective body. The characterizing features reside in such that, based upon fed image data, required images are formed on an image-transferable sheet acting for image carry-over service and in reliance on sublimation image transfer technique, and then, by the use of said sheet with said images thus formed thereon, the formed images thereon are transferringly applied on the objective body. By adopting the above measures, the objective body can be formed sharply and clearly with any desired images, irrespective of kind and configuration thereof, with such superior results of highly improved unity and solidability between the formed images and the objective body to be decorated with.

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.
