PURPOSE:To prevent a sheet base from being wrinkled and enable re-adhesion of the sheet base and an opaque layer through releasing a part of a release layer, by a construction wherein a pressure sensitive adhesive sheet comprising the release paper adhered to one side of the opaque layer is partly adhered to a transparent or semitransparent sheet base. CONSTITUTION:A base sheet 4 comprises a sheet base 3 and a releasable coat layer 2, whereas a pressure sensitive adhesive sheet 11 comprises a release paper 5 adhered to an opaque layer 7 by an adhesive layer 6, and a part of the release paper 5 is removed for partial adhesion of the opaque layer 7 to the base sheet 4. The release paper 5 is provided with cutting lines 8 at regular intervals. Since the opaque layer 7 is light-reflective or light-absorptive, the presence or absence, the position or the like of this printing paper can be detected by a reflection- or transmission-type photosensor. Wrinkling or the like does not occur due to differences between coefficients of expansion of the layers, and even when the opaque layer is separated from the sheet base by cutting off a part provided with a transferred image, the opaque layer can be again adhered to the sheet base by removing a part of the release paper, and the sheet can be used as a new sheet. |
