Abstract

(57) [Summary] [Purpose] An adhesive paper that can be used for any application that requires the function of a non-peeling or peeling adhesive with one sheet of paper. [Structure] A non-peeling pressure-sensitive adhesive 3 is applied to one surface of the non-peeling pressure-sensitive adhesive 3 that cannot be peeled after bonding, while a peelable pressure-sensitive adhesive 4 that can be peeled after bonding is applied to the other surface. Since three coated surfaces or a peelable pressure-sensitive adhesive 4 coated surface can be selected and used, it can be used in the same manner as two adhesive sheets having adhesives having different properties such as non-peeling property and peeling property.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an adhesive paper coated with an adhesive.

[0002]

[Prior Art]

 Although this type of paper has been known for a long time, in the past, adhesive was applied to only one side of the paper, or even when it was applied to both sides of the paper, either non-peelable or peelable adhesive was applied. It is usual to apply the agent.

[0003]

[Problems to be solved by the device]

 For this reason, in the past, a non-peelable or releasable adhesive was selected according to the application and then applied to the paper to create an adhesive paper. Alternatively, there is the inconvenience that it cannot be commonly used in applications requiring a peelable adhesive function.

The present invention eliminates such inconvenience and provides an adhesive paper that can be used for any application requiring a non-peeling or peeling adhesive function with one sheet of paper. To aim.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the adhesive paper of the present invention is coated with a non-releasing adhesive that cannot be peeled off after bonding on one side, and a peelable adhesive that can be peeled off after bonding on the other side. It is a thing.

[0006]

[Action]

 By selecting and using the non-peelable adhesive-coated surface or the peelable adhesive-coated surface of the adhesive paper, it can be used in the same manner as two adhesive papers each having an adhesive having different properties.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, FIG. 1 is a schematic cross-sectional view of an adhesive paper, FIG. 2 is a schematic cross-sectional view showing a printing state when a folded postcard is prepared using a non-peeling adhesive, and FIG. Is a schematic cross-sectional view of a postcard that is also made, FIG. 4 is a schematic plan view showing the front side, FIG. 5 is a schematic plan view showing the back side, and FIG. 6 uses a peelable adhesive. Fig. 7 is a schematic cross-sectional view showing the print state when creating a concealed postcard in half, Fig. 7 is a schematic sectional view of the same concealed postcard, and Fig. 8 is a partially opened concealed postcard. It is a schematic perspective view shown.

As shown in FIG. 1, the adhesive paper 1 can be adhered to one surface side of the paper 2 under a certain condition, for example, a pressure-sensitive non-peeling pressure-sensitive adhesive that cannot be peeled after bonding. 3 is applied, and the other side of the sheet 2 is also adhered when given a constant condition, for example, a pressure-sensitive peelable pressure-sensitive adhesive 4 that is peelable after adhesion is applied. .. These adhesives 3 and 4 can be printed or printed by various printers and printing machines. The non-peeling pressure-sensitive adhesive 3 may be an ordinary pressure-sensitive adhesive that has been conventionally used, but natural rubber latex is preferable, and more specifically, it is more specifically based on 100 parts by weight of natural rubber. The natural rubber latex obtained by graft-copolymerizing 2 parts by weight of styrene and 10 parts by weight of methyl methacrylate may be added with 5 parts by weight of a terpene resin tackifier. On the other hand, the peelable pressure-sensitive adhesive 4 may have an adhesive force adjusted so that it can be peeled off without impairing the concealment information printed after the adhesion. However, it is preferable to add a fine particulate filler having an incompatibility to this. More specifically, there may be mentioned one obtained by adding 20 parts by weight of silica gel having an average particle size of 5 μm as a fine particulate filler exhibiting non-affinity to 100 parts by weight of the non-peeling pressure-sensitive adhesive 3. ..

Next, a method of making a double-fold postcard using the non-peeling pressure-sensitive adhesive 3 using the above-mentioned adhesive paper 1 will be described. As shown in FIG. 2, a folding perforation 5 is formed in the central portion of the paper 2 to divide it into a postcard upper paper 2a and a postcard lower paper 2b, and then the peeling pressure-sensitive adhesive 4 is applied to the postcard. The address information 6 is printed on the paper 2a side, while the notification information 7 is printed on the postcard bottom paper 2b side. Then, with the non-peelable pressure-sensitive adhesive 3 application surface facing inward from the folding perforations 5, the postcard upper paper 2a and the postcard lower paper 2b are folded and adhered by applying a predetermined pressure. ~ A folded postcard 8 shown in Fig. 5 is created.

Next, a method for making a folded covert postcard using the peelable pressure-sensitive adhesive 4 using the above-mentioned adhesive paper 1 will be described. Note that the same components as those of the above-mentioned folded postcard 8 will be described with the same reference numerals. As shown in FIG. 6, after folding perforations 5 are formed in the central portion of the paper 2 to divide it into postcard top paper 2a and postcard bottom paper 2b, it should be concealed on the peelable pressure-sensitive adhesive 4 coated surface. Concealment information 9 such as a deposit balance and a loan repayment balance, which is notification information, is printed. The address information 6 is printed on the side of the postcard paper 2a and the notification information 7 is printed on the side of the postcard bottom paper 2b on the surface where the non-peeling pressure-sensitive adhesive 3 is applied. Then, the peelable perforation 5 is peeled off. The postcard upper paper 2a and the postcard lower paper 2b are folded over with the coated surface of the pressure-sensitive adhesive 4 inside, and a predetermined pressure is applied to bond them. A two-fold concealed postcard 10 is created in which the overlapping adhesive surface shown can be peeled off. As shown in FIG. 8, when the postcard top sheet 2a and the postcard bottom sheet 2b are separated from each other in the double-folded concealed postcard 10, the concealed concealment information 9 can be visually recognized.

The present invention is not limited to the above-described embodiments, and for example, the adhesives 3 and 4 are not limited to those mainly composed of natural rubber, and also heat-sensitive or re-wettable adhesives other than pressure-sensitive adhesives. It may be an agent. It can also be applied to tri-fold postcards and various cards other than bi-fold postcards.

[0012]

[Effect of the device]

 As is apparent from the above description, according to the present invention, the adhesives having different properties of non-peeling property and peeling property are applied to the front and back surfaces of the paper, respectively. It has two adhesive functions, and by appropriately selecting the adhesive application surface according to the application, it can be used like two adhesive papers each having an adhesive having different properties.
