る。Several types of postcards of this type are already on the market, but none of them are satisfactory in terms of performance or cost. For example, in the case of the label described in Japanese Utility Model Application Publication No. 63-6870, peeling occurs from a non-adhesive resin layer other than the adhesive layer that is the bonding surface, and once the label is removed from the postcard, it cannot be easily reattached. However, since the adhesive labels used have a multilayer structure, many steps are required to manufacture them, making the manufacturing cost extremely high. The cost advantage resulting from the low price is small.

等の欠点を有する。[0004] In addition, a confidential postcard made by folding in half a sheet obtained by mixing polyolefin fibers and natural pulp is cheaper to produce than the above-mentioned postcards, but
The ink layer provided by printing on postcards inhibits the adhesion of polyolefin fibers to each other due to heat during bonding, which imposes restrictions on printing design. Alternatively, since the paper that can be used as a postcard is limited to the mixed paper sheet, there are disadvantages such as not being able to obtain printed matter that looks as good as when using coated paper.

発明を完成するに至った。[Means for Solving the Problems] As a result of studies, the present inventors have found that by selecting the composition of the pressure-sensitive adhesive layer, it is possible to reproduce printing with a good appearance without using an expensive sheet with a multilayer structure. It was discovered that a peelable postcard can be obtained, and the present invention was completed.

The adhesive layer contains an adhesive having a glass transition point in the range of -100°C to 20°C and a pigment as basic components, and the pigment is in the range of 10 to 500 parts by weight based on 100 parts by weight of the adhesive.

4 is a perspective view showing a removable pressure-sensitive adhesive postcard of the present invention, and FIGS. 5 to 8 are plan views of the postcard of FIGS. 1 to 4, respectively. The postcard is made by printing information on at least one of the pressure-sensitive adhesive sheet and adhesive sheet obtained by providing an adhesive layer with a specific composition on a support, and then pressing the adhesive layer as shown in the figure. It is obtained by pressurizing and bonding them together. In this case, the pressure-sensitive adhesive sheet is usually used as a label, and the adhesive sheet is used as a postcard.

Among these, a more preferable one is one in which the adhesion suppressing layer is provided in the form of a tint pattern, as shown in the perspective view of FIG. 10 to 14 are specific examples of plan views showing the coating pattern of the adhesion suppressing layer provided on the adhesive layer of the pressure-sensitive adhesive sheet of the postcard of FIG. 9.

FIG. 15 is a plan view showing a continuous sheet for postcards, which is obtained by printing personal information using a line printer or the like after base printing and perforation and marginal processing are performed on the adhesive sheet. FIG. 16 is a plan view showing a continuous sheet for labels.
A colored adhesion suppressing layer is provided in the form of a background pattern on the adhesive layer of a pressure-sensitive adhesive sheet formed by providing an adhesive layer on a support, and if necessary, base printing is performed on the front and/or back side of the sheet. , followed by perforation and marginal punching as shown in the figure. FIG. 17 is a plan view showing a configuration in which the continuous sheet for labels of FIG. 16 is stacked on the continuous sheet for postcards of FIG. After cutting along the perforations, a pressure treatment is performed to form a removable postcard shown in the plan view of FIG.

性が劣ったり接着性が劣ったりする傾向が見られる。Examples of the adhesive used to form the adhesive layer of the pressure-sensitive adhesive sheet of the present invention include ethylene-vinyl acetate resin, (meth)acrylic acid ester resin, vinyl chloride resin, and vinylidene chloride resin. Resins, synthetic rubber resins, natural rubber resins, etc., with a glass transition point of -1
00 to 20°C is used. Among these, (meth)acrylic acid ester copolymers are particularly preferred because their adhesive strength is stable over time. Incidentally, if the glass transition point is outside this range, there is a poor balance between removability and adhesiveness, and there is a tendency for the removability to be poor or the adhesiveness to be poor.

Examples include melamine resin particles, benzoguanamine resin particles, starch particles, etc., and 10 to 500 parts per 100 parts of adhesive.
It is used in an amount of 30 to 250 parts by weight, preferably 30 to 250 parts by weight. Incidentally, if less than 10 parts by weight is added, re-peelability will be insufficient, while if more than 500 parts by weight is added, there is a high risk of unintended peeling. In addition, as a pigment, BE is used because it has the advantage that the resulting sheet has less blocking tendency and has excellent printability.
Those having a specific surface area measured by the T method in the range of 10 to 200 m2/g are preferable, and those in the range of 20 to 50 m2/g are particularly preferable.
