DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIG.
~ It demonstrates based on FIG. As shown in FIG. 1, the printing sheet 10 of the present embodiment has a double-sided surface between a release paper 20 having a release surface 11A on one side and a printed sheet 19 having a release surface 13A on one side. Adhesive surface 15A, 16A
The transparent double-sided pressure-sensitive adhesive sheet 18 is sandwiched between the pressure-sensitive adhesive surfaces 15A and 16A and the peeling surfaces 11A and 13A so that they can be peeled off.

More specifically, it is as follows. That is, the double-sided pressure-sensitive adhesive sheet 18 has, for example, a thickness of 15 to 2
A transparent adhesive is applied to both surfaces of the resin sheet 17 as a transparent support of 0 [μm] to form the adhesive layers 15 and 16, so that both surfaces become the adhesive surfaces 15A and 16A. Here, in the transparent pressure-sensitive adhesive, the bonding force between one pressure-sensitive adhesive surface 16A and the peeling surface 11A of the release paper 20 is stronger than the bonding force between the other pressure-sensitive adhesive surface 15A and the peeling surface 13A of the printing target sheet 19, and Printing surface 1 of printing sheet 19 described later
4B and the adhesive surface 15A are mixed to be weaker than the bonding force.

The release paper 20 has the release surface 11A formed by applying a release agent to one surface of the paper 12 having a thickness of about 50 [μm] to form the release layer 11.

The sheet 19 to be printed is coated with a release agent on one side of a resin sheet 14 made of transparent polyethylene terephthalate (hereinafter referred to as "PET") having a thickness of about 100 [μm] to form the release layer 13. By forming it, one surface becomes the peeling surface 13A, and the other surface becomes PE.
T itself is exposed to form a printed surface 14B to which ink or the like can be attached.

Both the print-receiving sheet 19 and the double-sided pressure-sensitive adhesive sheet 18 are half-cut in advance into a line-symmetrical shape, for example, a rectangular shape (see the half-cut line L2 in FIG. 1).

Next, the function and effect of the printing sheet 10 of the present embodiment having the above-mentioned structure will be described. First, in a printer such as an inkjet, a laser, a thermal transfer type or a thermal recording type, a paint I such as ink or carbon is applied to the inside of the half cut line L2 on the printed surface 14B of the printed sheet 19.
Apply and print a character graphic. Here, when printing a character graphic, the character graphic is printed on a transparent member and the shape viewed from the back side is printed. Specifically, as shown in FIG. 1, for example, the letters “ABC” are inverted and printed as viewed from the back.

Next, the rectangular sheet portion 14D inside the half-cut line L2 of the sheet to be printed 19 is peeled off from the double-sided adhesive sheet 18. At this time, the adhesive force between the adhesive surface 16A on one side of the double-sided adhesive sheet 18 and the releasing surface 11A of the release paper 20 is stronger than the adhesive force between the adhesive surface 15A on the other side and the releasing surface 13A of the print-receiving sheet 19, so that it is rectangular. Seat part 14D
2, the rectangular sheet portion 14D alone is peeled off from the double-sided adhesive sheet 18 while the double-sided adhesive sheet 18 remains attached to the release paper 20 side, as shown in FIG.

Next, the rectangular sheet portion 14D is turned upside down, the printed surface 14B side of the rectangular sheet portion 14D to which the paint I is attached is directed to the adhesive surface 15A, and the half cut of the main body portion 14E of the printed sheet 19 is performed. Inner depression 2 of line L2
Press in 1. At this time, the half-cut shape of the print-receiving sheet 19 is a line-symmetrical rectangle, and therefore the rectangular sheet portion 14D can be aligned inside the half-cut line L2 even when turned over. As a result, as shown in FIG. 3, the peripheral edge of the printed surface 14B of the rectangular sheet portion 14D and the peripheral edge of the half-cut adhesive surface 15A can be aligned and joined together.

When the printing sheet 10 is viewed from above in FIG. 3, the character "ABC" (see FIG. 1) printed by reversing the printing surface 14B is the transparent printing sheet 1
It will be seen from the back through 9 and the regular character "AB
C ”(see FIG. 5).

Next, the double-sided adhesive sheet 18 is attached to the release paper 20.
Remove from. At this time, the adhesive surface 1 of the double-sided adhesive sheet 18
The joining force between 6A and the peeling surface 11A of the release paper 20 is weaker than the joining force between the printing surface 14B of the printing sheet 19 and the other adhesive surface 15A, so that the rectangular sheet portion 14D can be simply peeled off. As shown in FIG. 4, with the double-sided adhesive sheet 18 integrally attached to the rectangular sheet portion 14D,
It is peeled off from the release paper 20. Then, as shown in FIG. 5, the rectangular sheet portion 14D is attached to the wall W so that the character "A
BC ”is displayed.

As described above, the printing sheet 1 of this embodiment
