CONSTITUTION:A pattern layer 6 due to colorant ink is provided to the rear of a cover film 1 and a developer layer 9 is provided on the surface of the passbook 2 to which the cover film 1 is bonded and the colorant ink is adsorbed on the developer of the developer layer when the cover film 1 is bonded to the passbook 2 so as to cover an affixed seal 3 to develop a color pattern on the surface of the developer layer 9. Therefore, when the cover film is unjustly peeled off to be replaced with a new cover film, it becomes difficult to match a newly developed color pattern with the color pattern already developed on the passbook and it can be discriminated that the cover film is altered at a glance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing improper use of a seal sticker attached to the surface of an adherend such as a bankbook for passbooks, and a passbook provided with the method for preventing improper use.

[0002]

2. Description of the Related Art In a bank passbook, a stamp field for stamping a depositor's registration stamp is provided on the cover, etc., and the imprinter stamped in this stamp column verifies and confirms the depositor himself. There is. By the way, it has been customary in the past to directly provide the stamp field directly on the surface of the passbook by printing. In that case, after imprinting the depositor's seal on the imprinted column, the imprint may remain exposed, but in general, to protect the imprint and prevent tampering, the imprinted surface is transparent. A protective film is attached.

However, only by covering the imprint with a protective film in this manner, the protective film can be easily peeled off by heating with an iron or a hair drier, for example, so that the imprint may be erased and tampered with. Yes, it is not sufficient as a tamper-proof measure. Therefore,
In order to deal with such a problem, for example, Jikho Sho 58-2
In the one described in Japanese Patent No. 0380, a printing layer made of an irreversible thermosensitive coloring ink is provided in a stamp field of a passbook, the surface thereof is masked with a transparent seal film, and the transparent seal film is peeled by heating with an iron or the like. In such a case, it is possible to see at a glance that the irreversible thermosensitive coloring ink has developed color and has been tampered with.

However, in the conventional ones including those disclosed in the above publications, generally, the stamp field is directly printed on the surface of the deposit passbook, so that the depositor uses the seal stamp each time the passbook is updated. It was necessary to bring it to the office, and the bank also had to perform the collation confirmation work of the imprint every time it was updated, and both sides were complicated and troublesome. Therefore, as a solution to such a problem, a seal imprint sticker in which a seal stamp column is printed and which can be transferred to a new passbook when the passbook is updated is disclosed in, for example, Jikkei 3-645.
No. 1 publication. In the publication described in the publication, a seal imprint provided with a seal part for imprinting a seal on the surface and a part for entering a confirmation code for distinguishing from other seal imprints, and affixed and fixed on the surface of this seal imprint A transparent protective film, a non-adhesive part for peeling, and a slit for breakage at the time of peeling are formed respectively, and an appropriate color that is transparent is applied. When the passbook is to be renewed with the covering film that is attached and fixed, and when updating the passbook, after peeling off the covering film by holding the non-adhesive part, the seal imprint with the protective film attached is used. Peel it off the surface of the passbook, attach it to a new passbook, and then attach and fix a new covering film on top of it to reduce the complexity of renewal as described above and to prevent damage when peeling off the covering film. So as to prevent fraud such as imprint tampering by the slit.

[0005]

However, the above-mentioned actual fairness 3
In the one described in Japanese Patent No. 6451, in order to enhance the fraud prevention effect by replacing the seal imprint seal (imprint seal), there is a means for preventing reuse of the cover film by making a cut in the cover film so that the cover film is easily damaged. If a new cover film is available, it can be apparently restored to its original state after improperly replacing the seal imprint seal.
Therefore, unless the number of cover films is strictly controlled, there is a problem that the seal cannot be discriminated even if the seal imprint (imprint seal) is improperly replaced.

The present invention has been made in view of the above problems, and a method of preventing improper use of a seal sticker and a method of preventing the improper use of the seal sticker, which can enhance the effect of suppressing improper replacement of the seal sticker. The purpose is to obtain a passbook that has been subjected to.

[0007]

A method for preventing unauthorized use of a marking seal according to the present invention is intended to prevent unauthorized use of a marking seal which has a marking portion and which is covered with a cover film and is removably attached and fixed to an adherend. A method, wherein a pattern layer is formed on the adhesive layer surface of the cover film with a color-forming agent ink, and
On the surface of the adherend where the cover film is attached, a developer layer that develops color with the color-forming ink is provided, and when the adhesive part of the cover film is attached and fixed to the adherend, a pattern is applied to the developer layer. The feature is that it is made to color.

The passbook which has been subjected to the illegal use preventing method is a passbook in which a seal is stuck and fixed to a predetermined portion by a cover film, and the cover film is provided with a pattern layer made of a coloring agent ink on the adhesive layer surface. The surface of the passbook at the position where the cover film is attached is provided with a developer layer that develops color with the color-forming ink, and the adhesive layer of the cover film is attached to the passbook and fixed. The feature is that the design is made to color.

[0009]

[Function] When a passbook or the like is created, a seal with a registration stamp of the depositor is placed at a predetermined position on the surface of the adherend such as the passbook, and a cover film is put on the sticker to fix it.
When rubbing with a fingertip to apply pressure, the color developer on the surface of the adherend reacts with the color developer ink provided on the surface of the adhesive layer of the cover film to develop the color, whereby the pattern emerges. Then, when the seal seal is normally transferred in the bank, the cover film is peeled off, so that the seal seal can be easily transferred to the new passbook. Also, if the cover film is illegally peeled off and replaced with a new cover film, it is possible to distinguish at a glance that the newly developed pattern does not match the pattern that has already developed color on the adherend. Become.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a passbook according to an embodiment of the present invention, FIG. 2 is a plan view of a cover film in the same embodiment,
FIG. 3 is a cross-sectional view of the sticking part of the cover film.

The cover film 1 of this embodiment covers the surface of the marking seal 3 attached at a predetermined position on the back of the bank passbook 2 and cuts the biaxially stretched polyester film into a substantially rectangular shape. It is formed by doing. On the back surface of the cover film 1, a gluing portion 4 (an outer portion of the one-dot chain line in FIG. 2) in which an adhesive is applied to a predetermined width of the entire circumference excluding the upper portion (knob portion) of the short side on one side, A pressure-sensitive adhesive layer including a glue-fixing portion (inside portion) 5 to which no pressure-sensitive adhesive is applied, which is provided in a portion surrounded by the gluing portion 4, is formed. Also, these gluing parts 4
And on the surface of the glue-fixing portion 5, a pattern layer 6 is formed by flexographic printing or gravure printing using color-developing ink on the entire surface.
Is provided. Here, the color former ink is a colored ink having transparency used for pressure-sensitive copying paper (carbonless paper), in which microcapsules containing oil droplets containing an electron-donating organic color former as a core substance. It is built in. The pattern of the pattern layer 6 is, for example, as shown in FIG.
The pattern is formed by a continuous tint block of the characters DNP as shown in FIG. In this case, this pattern is formed to such an extent that the adhesive force of the gluing portion 4 is not hindered, and the size of each character is desirably changed line by line as illustrated.

The cover film 1 has a gluing portion 4
Release paper is temporarily attached to and used. When the pattern layer 6 is provided on the back surface of the cover film 1, the
As shown in FIG. 1, the cover 8 and the release paper 7 are adhered to each other, and the printing unit 8
A method is used in which the pattern layer 6 is provided, and then the pieces are attached again in-line and transferred to the half blanking process.

Further, a developer layer 9 having a slightly larger coating shape than the cover film 1 is provided in advance on the portion of the passbook 2 where the marking sticker 3 is attached. Here, the color developer layer 9 is formed by layering a substance composed of an electron-accepting organic color developer by means such as printing or coating, and is combined with the color-developing ink on the back surface of the cover film 1. To produce a colored color. It is preferable that the color of the color former ink itself and the color after color development are different.

The marking seal 3 attached to the surface of the developer layer 9 is formed by attaching a protective transparent laminate seal 11 to the surface of a paper base seal 10. Here, the base seal 10 is provided with columns such as a registration mark of a depositor and a verification mark on the bank side on the front surface by printing, and a weak adhesive is applied on the back surface. Then, after stamping or the like on a predetermined column of the substrate seal 10, the laminate seal 11 is attached to the surface thereof. An adhesive is applied to the surface of the base seal 10 on the laminate seal 11, and a release paper is applied to the applied surface so that the laminate seal 11 adheres to the surface of the base seal 10 only on one side before use. It is temporarily attached. The base seal 10, the laminate seal 11 and the release paper interposed in between are used by temporarily attaching the back surface of the base seal 10 to the surface of the mount formed by the release paper, with three sheets as one set. To be done.

With the above configuration, when a new account is opened in a bank,
On the bank side, first, the base seal 10 is placed on the surface of the developer layer 9 provided at a predetermined position on the back side of the passbook 2 and once attached, and the depositor's registration stamp is placed in the seal column on the surface of the base seal 10. And after marking the bank's verification mark and filling in the prescribed items,
The release paper on the back surface of the laminate seal 11 is peeled off, and the laminate seal 11 is attached to the surface of the base seal 10.

Next, the cover film 1 is peeled off from the release paper and attached to the surface of the passbook 2 so as to cover the surface of the marking sticker 3. At this time, the surface of the marking seal 3 is brought into contact with the glue stopping portion 5 of the cover film 1. In addition, pressure is applied to the periphery of the cover film 1 so that the adhesive on the back surface of the cover film is made to conform to the surface of the passbook 2, and the coloring agent ink is adsorbed to the color developer to develop the pattern. To do so. In addition, in FIG.
The portion indicated by the solid line of the letters DNP is the colored portion.

According to this embodiment, when the cover film 1 is illegally peeled from the passbook 2 and replaced with a new cover film for the purpose of tampering with the imprint of the seal 3, the color has already been formed on the passbook. It is necessary to match a newly developed pattern with the existing pattern, and this pattern matching is very difficult, so that it is possible to prevent the cover film 1 from being illegally used.

When the bankbook 2 has been used and is to be renewed, the edge of the glue-fixing portion 5 (knob portion) formed on one side (right side) of the cover film 1 on the bank side is renewed.
The cover film 1 is peeled off from the surface of the passbook 2 by pinching, and the seal 3 made up of the substrate seal 10 and the laminate seal 11 is taken out. Then, this is attached to a new passbook and its surface is covered with a new cover film. In that case, the seal 3 can be taken out quickly and easily by peeling off the cover film 1 while holding the knob portion.

FIG. 5 shows a modification of the pattern forming pattern on the back surface of the cover film. In this example, when a pattern (for example, a tint block of a DNP character) is formed on the back surface of the cover film 12 with a color developer ink as shown in the figure, the width direction and the flow direction of the original film 13 (the arrow shown at the top of the figure) The repeating pitch of the pattern in the direction) is made unequal, and the printing pitch A in continuous printing and the punching pitch B when punching the individual cover films 12 are made different. By doing so, the patterns of the individual finished cover films 12 are different from each other. Therefore, as described above, the cover film is illegally peeled off for the purpose of tampering with the imprint, and the pattern is replaced with a new cover film. When it is matched, it becomes almost impossible to match the pattern, and the fraud prevention effect can be further enhanced.

FIG. 6 is a plan view of a cover film according to another embodiment of the present invention. Cover film 1 of this example
In the case of No. 4, a total of six discontinuous cuts 15 are formed in each of the upper and lower parts in such a manner that the boundary lines between the gluing part 4 and the gluing part 5 partially overlap each other. The other configurations are the same as those of the previous embodiment.

According to this embodiment, when the cover film 14 is illegally peeled from the passbook 2 for the purpose of tampering with the imprint of the base seal 10, the gluing part 4 remains on the surface of the passbook 2 and the upper part 3 Since the cover film 14 is torn so that each of the notches 15 in the bottom and the bottom three are continuous,
The fractured shape becomes jagged and difficult to reproduce. Therefore, it is possible to more clearly determine that the information has been tampered with.

In each of the above-mentioned embodiments, the one using the colored coloring agent ink having transparency has been described.
The color former ink may be colorless and transparent.

In each of the above embodiments, the pressure-sensitive adhesive layer on the back surface of the cover film is divided into the gluing portion and the gluing portion, but there is no problem even if the entire surface of the pressure-sensitive adhesive layer on the back surface is constituted by the gluing portion. There is no.

When the developer is applied to the surface of the passbook, the area of application is not necessarily limited to a slightly larger area than the cover film, and it may be applied to the entire face of the passbook, for example.

As the material of the cover film, in addition to the above-mentioned biaxially stretched polyester film, a biaxially stretched polypropylene film or polyvinyl chloride can be used.

[0027]

The present invention is configured as described above,
If the cover film is illegally peeled off and the seal imprint is tampered with, if you try to replace the cover film with a new one, it will be difficult to match the pattern that has already been colored on the passbook with the newly developed pattern, and it will be tampered with. Since it is possible to determine at a glance what has happened, it is possible to enhance the effect of suppressing improper replacement of the seal.
