2. Description of the Related Art Generally, business cards are created by letterpress printing, but with the spread of electrophotographic copying machines and printers, it is possible to create original business cards using these. Printing paper is becoming popular. In particular, if you enter information such as characters and images using a word processor or personal computer and print this information on a printing paper for business cards using an inkjet printer or laser beam printer, you can easily and inexpensively print business cards when needed. Can be created.

According to the above method, even if the information such as the department or telephone number changes, a business card containing new information can be immediately created. In this method, it is also possible to use a printing paper for business cards on which characters and figures are already partially printed. Furthermore, this method is
It is suitable for making relatively small printed materials such as shelf labels and name tags.

Conventionally, as a printing paper for business cards, a type of high-quality paper in which perforations are sized like business cards has been generally used. With this type of printing paper, the business card is cut off along the perforations after printing, but the operation of cutting off the perforations over the entire circumference is complicated, requires attention, and the end of the business card becomes uneven. There are drawbacks.

Therefore, there has been proposed a printing sheet in which a printing paper is cut into a frame serving as a support and a plurality of independent cards, and each card is fixed to the support with an adhesive tape (Japanese Patent Laid-Open No. 8-2151). Japanese Patent Laid-Open No. 11-78310
Issue). This printing sheet can be printed because the support and each card are integrated with an adhesive tape, and after printing, if each card is peeled from the adhesive tape, a card-like printed matter such as a beautiful business card can be printed. Can be obtained.

With the recent spread of such printing sheets, for example, double-sided printing is possible, clear images can be printed, and card-shaped printed matter as an information carrier is applied to various applications. It has become desirable to be able to do so. However, conventional printing sheets have not been able to meet these various requirements.

BEST MODE FOR CARRYING OUT THE INVENTION Regarding the printing sheet of the present invention,
A description will be given with reference to the drawings. FIG. 1 is a cross-sectional view showing a layer structure of an example of a laminated sheet used in the present invention. A printing sheet obtained from this laminated sheet and each card obtained from the printing sheet also have the same layer structure. ing.
The first sheet base material 1 is provided with an ink receiving layer 3 that can be inkjet printed, for example, as a printable surface on one side of the sheet base material main body 4. The second sheet base material 2 is provided with an ink-receptive layer 8 that can be inkjet printed on one side of the sheet base body 7 as a printable surface. The first sheet base material 1 and the second sheet base material 2 are laminated via the release agent layer 5 and the pressure-sensitive adhesive layer 6 to form a laminated sheet.

This laminated sheet has, for example, FIGS.
As shown in, a frame for a support and a plurality of independent cards are cut, and each card is fixed to the support with an adhesive tape to form a printing sheet. By printing the printing sheet through an inkjet printer, desired information such as characters, figures, and photographs can be printed on the ink receiving layer 3 and / or the ink receiving layer 8. After printing, each card is peeled off from the adhesive tape. Each card is used as a business card, for example, according to the printed information recording content.

After printing, each card can be used while holding the laminated structure, but if necessary, as shown in FIG. 1, it has a card piece 9 having a release agent layer and an adhesive layer. It can be peeled off from the card piece 10 and used for the purpose according to each information recording content and function.
For example, the card piece 9 having the release agent layer can be directly used as a business card or the like. On the other hand, since the card piece 10 having the adhesive layer is an adhesive sheet, it can be attached to a desired adherend. Further, the card piece 10 having this adhesive layer can be used as a memo paper.

As the first sheet base material 1 , both sides of the sheet base material body 4 may be printable surfaces. As a specific example, it is possible to use, as the first sheet base material 1 , an inkjet recording paper having a structure in which an ink-jet printable ink receiving layer is provided on both surfaces. In this case, if a printing layer is provided in advance on the back surface of the first sheet base material 1 , that is, the surface on the release agent layer side, the card is delaminated and the card piece 9 having the release agent layer is used as a business card or the like. When used, necessary information can be displayed on the back surface of the card piece 9 .

As a method for producing a laminated sheet having a layer structure as shown in FIG. 1, a release agent is applied to one surface of the first sheet base material (A) and dried to form a release agent layer, A method may be mentioned in which a pressure-sensitive adhesive layer is formed on the release agent layer, and one surface of the second sheet base material (B) is bonded onto the pressure-sensitive adhesive layer. A pressure-sensitive adhesive layer may be provided on one surface of the second sheet base material (B) and bonded to the release agent layer of the first sheet base material (A). The sheet base materials (A) and (B) are arranged such that at least the printable surface is on the outside of the laminated sheet. The laminated sheet, because the release agent layer and the pressure-sensitive adhesive layer are adjacent to each other, when the layers are peeled, the first sheet base material (A) layer having the release agent layer, and the second sheet base material having the pressure-sensitive adhesive layer ( B) can be separated into layers. Therefore, a card formed from this laminated sheet can be delaminated as well.

Examples of the first sheet base material and the second sheet base material having a printable surface on at least one side are, for example,
Paper, film, sheet, inkjet recording paper, etc.
Various printers such as an electrophotographic copying machine, a laser beam printer, and an inkjet printer, and those capable of printing / copying with a copying machine are preferably used.
