DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a notification stamp display which prevents a seal imprint of a notification stamp attached to a passbook or the like from being copied and misused.

[0002]

2. Description of the Related Art Conventionally, the seal imprint of a notification stamp used for a bank passbook can be easily replaced with a new passbook so that no improper operation is performed at the time of updating the passbook. In order to save money and improve operational efficiency at the bank, a seal sticker with an area for displaying the seal of the notification seal was attached to the passbook, and a covering film was attached to the passbook covering the entire seal. A passbook using a notification seal is used. When withdrawing a deposit using a passbook at the bank counter, fill out the cash withdrawal slip with the specified items, seal it with the notification stamp with the seal stamped on it, and then use the cash withdrawal slip. There is a method of withdrawing cash, and unless the person has a notification seal, cash cannot be withdrawn using a passbook. However, in such a cash withdrawal method, even if you do not have a notification stamp, the seal imprint displayed on the notification sign display attached to the passbook is copied to a predetermined column of the cash withdrawal slip, There has been a drawback in that a cash withdrawal ticket is made in a state in which it is difficult to distinguish the cash withdrawal stamp from being stamped with the notification stamp, and cash is withdrawn using the cash withdrawal ticket.

[0003]

SUMMARY OF THE INVENTION The present invention prevents improper withdrawal of cash due to duplication of a seal imprint by making it difficult to copy a seal imprint displayed on a notification seal display attached to a bankbook. An object of the present invention is to provide a notification mark display body that can be used.

[0004]

Means for Solving the Problems A seal comprising a seal and a seal stamped thereon, and a cover film adhered to the passbook surface so as to cover the entire seal, wherein at least the seal is provided on an outer surface or an inner surface of the cover film. A notification sign display body having a structure in which a high-temperature decoloring layer that is opaque at normal temperature and decolors at high temperature is formed so as to cover the seal imprint of the seal. With this configuration, the seal is covered with the opaque and dark high-temperature decoloring layer at room temperature, so that the seal cannot be seen and the copy cannot be performed as it is. Even if you try to copy by erasing the decoloring layer, the high-temperature decoloring layer will immediately return to its original opaque and dark state unless the notification mark display is kept in a high temperature state. It is extremely difficult to copy a seal imprint by a normal copying method using a copying machine.
It is possible to prevent improper withdrawal of cash by copying the seal imprint on the cash withdrawal slip. On the other hand, at the counter of the bank, by providing a hot plate held at a predetermined temperature, the high-temperature decoloring layer is decolored by bringing the passbook notification sign display body into contact with the hot plate, so that the imprint can be seen. As the state, it is possible to collate with the seal imprint displayed on the notification seal indicator.

[0005] In the above-mentioned notification sign display, the high-temperature decoloring layer is decolorized in the range of 40 ° C to 70 ° C, so that the notification mark display can be depressed at a high temperature, for example, by pressing the notification mark display with a hand. Since the color layer cannot be erased, and it is necessary to use a heating device to erase the color layer, copying can be difficult.

[0006] In the notification sign display body, the seal is colored at least in an area where the seal is displayed on the surface of the seal in a colorless or light color at normal temperature and a dark color close to the color of vermilion at high temperature. In order to erase the color of the high-temperature decoloring layer by providing a high-temperature coloring layer and by setting the color-forming temperature of the high-temperature coloring layer higher by 2 ° C. to 20 ° C. than the decoloring temperature of the high-temperature decoloring layer. Even if the display body is heated, if the temperature exceeds the coloring temperature of the high-temperature coloring layer, the high-temperature coloring layer develops color and the seal becomes invisible. It is necessary to maintain the display at a high temperature in a temperature range of 2 ° C. to 20 ° C. higher than the decoloring temperature of the high-temperature decoloring layer.
Therefore, it is extremely difficult to copy the seal imprint of the notification seal display, and the effect of preventing unauthorized copying of the seal imprint is enhanced. On the other hand, at the counter of a bank, it is easy to maintain the temperature of the hot platen in a temperature range of 2 ° C. to 20 ° C. higher than the decolorizing temperature of the high-temperature decoloring layer. it can.

[0007] In the above-mentioned notification sign display body, since the seal is provided with a vermilion absorbing layer on the upper surface of the high-temperature coloring layer, the vermilion absorbing layer is stamped on the vermilion absorbing layer of the sealing seal. Does not impair.

FIG. 1 shows a first embodiment of a notification stamp display according to the present invention. As shown in FIG. 1 (a), the seal shape in which the notification stamp is displayed and the code is written is affixed to the corner of the passbook 1 in a releasable manner, as shown in FIG. A covering film 4 provided with a high-temperature decoloring layer 5 that is opaque dark at normal temperature and decolorized at high temperature to be transparent so as to cover the displayed imprint,
In this configuration, the seal is attached to one passbook so as to cover the entire seal 2. In this normal temperature state, since the seal 2 is covered with the opaque and dark high-temperature decoloring layer 5, the seal displayed on the seal 2 cannot be seen from the outside and cannot be copied. is there.

The cross-sectional shape of the first embodiment is, as shown in FIG. 1B, a seal 2 on which a seal 6 of a notification mark is displayed.
The transparent protective film 3 is laminated on the surface of the passbook 1 in a state where the transparent protective film 3 is laminated, and the transparent base material layer 4a and the adhesive layer 4b are covered so as to cover the whole of the pasted seal 2. The passbook 1 is covered with a cover film 4 having a structure in which a high-temperature decoloring layer 5 is provided on the surface of the transparent base material layer 4a so that the imprint 6 imprinted on the seal 2 with the high-temperature decolorization layer 5 is covered. This is a configuration attached to a surface. In the case of the present embodiment, the upper surface of the protective film 3 with which the pressure-sensitive adhesive layer 4b of the coated film 4 contacts is subjected to a release treatment, or the pressure-sensitive adhesive layer 4b of the surface of the coated film 4 which is in contact with the protective film 3 In order to eliminate the force, it is necessary to provide a non-adhesive layer on the surface of the adhesive layer 4b.

FIG. 2 shows a state in which the notification stamp display body of the first embodiment attached to the passbook is heated to a predetermined temperature, and the plan shape is stamped as shown in FIG. Since the high-temperature decoloring layer 5 covering the seal 2 was decolorized and changed to a transparent high-temperature decoloring layer 5 ′, the high-temperature decoloring layer 5 ′ was entered in the seal 6 and the code entry column 7 of the notification mark displayed on the seal 2. The code becomes visible from the outside. As shown in FIG. 2 (b), the cross-sectional shape of the notification mark display body is different from that in which the high-temperature decoloring layer 5 which is opaque and dark at normal temperature is decolorized and changed to a transparent high-temperature decoloring layer 5 '. Is the same as in FIG. The opaque and dark colored high-temperature decoloring layer 5 is changed to a transparent high-temperature decoloring layer 5 'by heating the notification mark display body to a predetermined temperature in this manner. Checking whether the imprint displayed on the cash withdrawal slip is correct with the imprint 6 displayed on the seal 2 by, for example, bringing the notified notification display body into contact with a hot plate heated to a predetermined temperature. It is possible to do. On the other hand, imprint 6
When it is attempted to make a copy, it is necessary to keep the notification mark display body at a predetermined temperature or higher, so that it becomes difficult to make a copy.

As shown in FIG. 3, the laminated structure of the notification stamp indicator according to the second embodiment of the present invention, as shown in FIG. A transparent protective layer 3a and a pressure-sensitive adhesive layer 4b so as to cover the whole of the seal 2 with the protective film 3 attached thereto. 4b, the coated film 4 having a high-temperature decoloring layer 5 which is opaque and dark at normal temperature and is decolorized at high temperature and becomes transparent is provided.
Is attached so as to be covered. With the configuration of the second embodiment, since the adhesive force of the adhesive layer 4b is lost at the portion where the high-temperature decoloring layer 5 of the covering film 4 is formed, it is necessary to perform a release treatment on the upper surface of the protective film 3. Disappears. The effect of the second embodiment is the same as that of the first embodiment.
Cannot be seen because the imprint 6 is completely covered, and therefore the imprint 6 cannot be duplicated. By heating, the opaque high-temperature decoloring layer 5 becomes a transparent high-temperature coloring layer 5 '.
Will be able to see to change.

As the composition constituting the high-temperature decoloring layer 5 used in the present invention, a compound having a phenolic hydroxyl group and a compound having a phenolic hydroxyl group among the electron-donating color-forming organic compound and the compound having a phenolic hydroxyl group are colorless electron-donating compounds. It is a compound in which three components of a compound (desensitizer) that chemically lowers the color-forming function in a reaction that changes into a colored form by acting on a color-forming organic compound, a so-called electron donating reaction, are appropriately blended. 3 above
By appropriately combining the components, the color can be changed from color to colorless at a certain temperature, and the combination of the color change temperature point and the color type can be freely adjusted. Select a color with an electron-donating color-forming organic compound, determine the concentration by coloring with a compound having a phenolic hydroxyl group, and further determine the type or combination of desensitizers such as alcohols, esters, ketones, and ethers. The color change temperature can be determined by the amount.

As the above composition which can be used as the high-temperature decoloring layer, for example, Metamocolor manufactured by Pilot Ink Co., Ltd. can be used. In particular, a dark color having excellent concealing properties such as black, brown, and deep blue at a low temperature and discoloring colorless when heated to a temperature of 40 to 70 ° C. can be suitably used. When the color is erased at a temperature of 35 ° C. or less, the color is erased by the body temperature, such as by pressing the hand, so that the copy can be performed by, for example, a method of copying while holding the report mark display body by hand. In the case where the color is erased at a temperature of 70 ° C. or more, there is a problem that the notification stamp display body and the passbook are deformed due to heat when the high temperature decoloring layer 5 is erased and the imprint is compared. Not preferred.

In order to form the high-temperature decoloring layer 5 on the surface of the coating film 4, the coating film 4 is formed by gravure printing, silk screen printing or the like using an ink having a composition in which the above composition is dissolved in a resin solution. By printing on the surface of the base material layer 4a or the surface of the pressure-sensitive adhesive layer 4b, the high-temperature decoloring layer 5 can be formed. Therefore, the high-temperature decoloring layer 5 can be formed at an arbitrary position on the surface of the coating film 4 in an arbitrary shape.

As shown in FIG. 4, the third embodiment of the notification mark display body of the present invention at normal temperature has a high-temperature coloring layer 8 formed on the upper surface of the seal 2 and a notification on the high-temperature coloring layer 8 surface. The seal 6 of the mark is displayed, and the transparent protective film 3 is laminated on the surface on which the seal 6 of the notification mark is displayed. The transparent protective film 3 is stuck releasably on the surface of the passbook 1 to form the high-temperature coloring layer 8. A covering film 4 composed of a transparent base material layer 4a and an adhesive layer 4b is adhered to one passbook so as to cover the whole of the stamp seal 2, and a high-temperature decoloring layer is provided on the transparent base material layer 4a of the covering film 4. Reference numeral 5 denotes a configuration formed so as to cover the seal 2. The high-temperature decoloring layer 5 is the same as that used in the first and second embodiments, and the high-temperature coloring layer 8 is colorless or light-colored at room temperature, and develops color when heated to a predetermined temperature to become dark. Those that change to vermilion are used. An inorganic fine powder such as silica, calcium silicate, or alumina may be added to the high-temperature coloring layer 8 in order to improve the suitability for printing on the surface of the high-temperature coloring layer 8.

As the notification mark display body is heated from the normal temperature state shown in FIG. 4, first, the opaque, dark high-temperature decoloring layer 5 is decolorized to a transparent high-temperature decoloring layer 5 '. Therefore, the seal 6 can be visually recognized. When the temperature is further increased by continuing heating, the state of the transparent high-temperature decoloring layer 5 'does not change, but the colorless or light-colored high-temperature coloring layer 8 develops color and changes to a dark vermilion high-temperature coloring layer 8'. Then, the imprint 6 imprinted on the surface of the high-temperature coloring layer 8 'which has developed a vermilion color becomes invisible. Therefore, in the case of the notification stamp display of the third embodiment, even if the seal 6 is to be copied, the high temperature decoloring layer 5
If the temperature is not accurately adjusted to a temperature higher than the decolorizing temperature and lower than the color forming temperature of the high-temperature color forming layer 8, copying cannot be performed, so that copying is extremely difficult, and the imprint 6 is copied and cash is withdrawn illegally. Can be prevented. On the other hand, at the counter of the bank, a hot platen whose temperature is adjusted to a temperature higher than the decolorizing temperature of the high-temperature decoloring layer 5 and lower than the coloration temperature of the high-temperature coloring layer 8 is installed at the counter of the bank. By bringing the notification stamp display body into contact with the hot platen, the seal 6 displayed on the seal 2 can be visually recognized, so that the seal 6 on the seal 2 can be compared with the seal of the cash withdrawal slip. .

As shown in FIG. 6, the notification stamp display of the present invention has a cross-sectional shape at normal temperature, as shown in FIG. The imprint 6 of the notification mark is displayed on the surface of the absorbing layer 9, and the transparent protective film 3 is laminated on the surface on which the imprint 6 is displayed, and is stuck on the surface of the passbook 1 in a releasable manner. A cover film 4 composed of a transparent base material layer 4a and an adhesive layer 4b is adhered to the passbook 1 so as to cover the entire stamp seal 2 on which the red film absorbing layer 9 is laminated. The structure is such that a high-temperature decoloring layer 5 is formed on the surface of the layer 4 a so as to cover the seal 2. By adopting the configuration of the fourth embodiment, the stamping is performed on the vermilion absorption layer 9 instead of the stamping on the high-temperature decoloring layer 5 as in the case of the third embodiment.
The sealability of the seal 2 is not impaired.

As the notification mark display body is heated from the state of normal temperature shown in FIG. 6, the opaque dark color high-temperature decoloring layer 5 is decolorized to a transparent high-temperature decoloration layer 5 ', and the imprint 6 is formed. Will be visible. When the temperature is further increased by continuing heating, the state of the transparent high-temperature decoloring layer 5 'does not change, but the colorless or light-colored high-temperature coloring layer 8 develops color and changes to a dark vermilion high-temperature coloring layer 8'. The imprint 6 stamped on the vermilion absorption layer 9 is invisible as in the case of the third embodiment. The vermilion absorption layer 9 is formed by adding an inorganic fine powder such as silica, calcium silicate, or alumina to a resin such as a cellulose resin, a poamide resin, or a chlorinated polypropylene.
It is formed by gravure printing, silk screen printing or the like on the surface of the high-temperature coloring layer 8 using a colorless ink having a composition added with 40% by weight.

The composition used for the high-temperature coloring layer 8 is preferably a colorless or pale color at room temperature and develops a dark vermilion color when heated. As the high-temperature coloring layer 8, for example, a thermo patch WR type manufactured by NOF Engineering Co., Ltd. can be used. WR-40
Is a type that changes color at 40 ° C., and exhibits a pale reddish yellow on a low temperature side and a deep reddish orange on a high temperature side.
In the third and fourth embodiments, by reducing the difference between the decolorizing temperature of the high-temperature decoloring layer 5 and the coloring temperature of the high-temperature coloring layer 8b, the temperature range in which the imprint can be visually recognized is narrowed. The effect of preventing copying is great. The temperature difference between the color erasing temperature of the high-temperature color erasing layer 5 and the color developing temperature of the high-temperature color developing layer 8 is 2 ° C.
Preferably, the temperature is 10 ° C. For example, the color erasing temperature of the high temperature color erasing layer 5 is set to 35 ° C.
° C.
