PURPOSE: To enable to print stable images with excellent wear-resistant property onto the surface of a writable and erasable film by a method wherein the images such as formats and the like, which are printed on a base material such as paper or the like with subliming dye ink, are heat-transferred.
CONSTITUTION: An adherent plastic film 2 and a writable and erasable plastic film 3 are co-extruded onto a sheet 1 serving as a support by T-die method so as to manufacture a laminated sheet produced by laminating the sheet 1, the film 2 and the film 3 to one another in the order named. The printed surface of an original sheet consisting of base material 4, onto which images 5 such as formats and the like have been printed in advance with subliming dye ink or subliming dye-containing toner, is put on the plastic film 3 of said laminated sheet so as to contact the printed images with the film 3 in order to sublimation- transfer the subliming dye of the printed images and, after that, to peel off the original sheet to form subliming dye images 6. The resultant format images consisting of subliming dye formed as mentioned above cannot be erased with an eraser, owing to the strong penetrating force of dye molecules.
