ロールに付着しトラブルを起こす等の問題があった。Further, when printing is performed using an electrophotographic copying machine or printer, it is necessary to cut into a predetermined size after printing. In order to omit this cutting work, the back side of the paper sheet is subjected to a tacking process in which a release agent layer, an adhesive layer and a supporting sheet are laminated, and after predetermined printing, cuts are made to cut out small pieces of paper. The method of applying was also done. However, in the case of tack processing, dust due to residual glue adhered to the back surface of the paper sheet, or the cut portion that was made in advance peeled off in the copying machine and the adhesive layer on the support sheet adhered to the copy roll. There was a problem such as causing trouble.

っている。On the other hand, a sheet which is temporarily adhered with a thermoplastic resin interposed between the printing base material layer and the supporting base material layer does not use an adhesive agent which causes the above troubles. Another trouble occurred when the sheet was electrophotographically printed. Conventionally, it has been thought that troubles such as printing fog and scumming are affected by the surface electric resistance, but unlike the conventional paper sheet, the above temporary adhesive sheet is different from the conventional printing sheet layer and the supporting substrate. Since the thermoplastic resin is interposed between the layer and the layer, the volume electric resistance is increased, which causes troubles such as print fog and background stain.

トを製造することができる。The factors controlling the adhesive strength between the printing base material layer and the intermediate layer or between the supporting base material layer and the intermediate layer include the type and layer thickness of the thermoplastic resin, and the thermoplastic resin. Whether to include additives in the layer, the type and amount used,
The strength of corona treatment on the surface of the base material layer, the strength of ozone treatment on the surface of the thermoplastic resin layer, the preheating temperature of the base material layer, the resin extrusion temperature and the like can be mentioned. Examples of additives for adjusting the adhesive strength include fatty acid amides such as oleic acid amide, stearic acid amide, and erucic acid amide. Usually, if any additive is added to the resin, the adhesive strength tends to decrease. In this sense, an antistatic agent, an antiblocking agent, an ultraviolet absorber, silicone or the like, which originally has another function, can be used as an additive that reduces the adhesive strength. Corona treatment and ozone treatment among the above-mentioned factors for controlling the adhesive strength are originally developed to obtain a high adhesive strength, but in the present invention, these treatments are performed for the resin layer and the base material layer respectively. On the other hand, it is possible to manufacture a laminated sheet which can be easily peeled off, by properly using it properly.

なる。FIG. 3 is a sectional view showing the laminated structure of a laminated sheet for electrophotography according to another embodiment. In this example, one thermoplastic resin layer containing a non-chargeable ionomer resin as an intermediate layer was laminated between a printing substrate layer having a resin layer on its surface and a supporting substrate layer to form a supporting layer. The adhesive strength between the base material layer and the thermoplastic resin layer is smaller than the adhesive strength between the printing base material layer and the thermoplastic resin layer. Therefore, since peeling occurs between the supporting base material layer and the thermoplastic resin layer, the notch penetrates through the printing base material layer and the thermoplastic resin layer and reaches just before the supporting base material layer. .
The business card made of the laminated sheet according to this example has a state in which the thermoplastic resin layer is laminated on the back surface after peeling.
