Abstract

PROBLEM TO BE SOLVED: To surely hide duplicated and hidden information, to prevent leakage of the information and to make the information clearly visible by protecting an adhesive layer with a release sheet and applying a carbon transfer agent on the exposed face of the release sheet. SOLUTION: A sheet set 1 with a duplicating and hiding label consists of upper and lower sheets (a) and (b), respectively, with a cutting perforation line d. A hiding sheet 3 which can not be seen through is joined with a first pseudo-adhering means 7a to the back side of the region (n) where an identification number is to be written of the upper sheet (a), and a see-through label base body 2 is joined to the lower side of the hiding sheet 3 with a second pseudo-adhering means 7b so that the sheet 3 and label base body 2 can be peeled off. Further, an adhesive layer 4 is applied on the lower face of the label base body 2. The adhesive layer 4 is protected with a release sheet 5, and a carbon transfer agent 6 is applied on the exposed face of the release sheet 5. Namely, the information is duplicated with the carbon transfer agent 6. After the release sheet 5 is peeled off, the label is adhered with the exposed adhesive to the region where the confidential information is duplicated. Further, when the hiding sheet 3 is peeled from the label base body 2, the sheet can not be returned into the original state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label for copying and concealment which is releasably attached to a predetermined portion of an upper sheet so that confidential information written on the upper sheet is clearly copied to a lower sheet, and the information is securely copied. The present invention relates to a sheet set with a label for concealing a copy concealment.

[0002]

2. Description of the Related Art Conventionally, forms that require copying, such as various application forms and registration forms, are usually formed by superposing a plurality of sheets, and information written or printed on an upper sheet is copied to a lower sheet. As shown, each sheet is provided with a copying means. Some of the information entered or printed is secret information, such as passwords and deposit balances, that must not be seen by others.In particular, the secret information copied to the lower sheet used by the form issuer as a copy is Some techniques for concealing even information processing have been conventionally developed.

[0003] In such a technique, for example, a transferable special ink containing a fluorescent pigment is applied to the back side of the secret information entry portion of the upper sheet so that the secret information cannot be seen without irradiating ultraviolet rays. A technology that makes it difficult to view the secret information copied to the lower sheet by applying a tint block printing to the secret information copy section of the lower sheet corresponding to this secret information entry section, or a weak adhesive to the label base that cannot be seen There has been conceived a method in which a peelable concealing label provided with a layer is attached so as to cover the secret information copied to a secret information copying section of a lower sheet to conceal the information.

[0004]

However, there is a problem with such a conventional technique. For example, in a method using a transferable special ink containing a fluorescent pigment, not only can secret information be read easily with the spread of commercially available hand-held type UV irradiators, but there is no trace with UV irradiation. Since it does not remain, there is an inconvenience that leakage of secret information cannot be confirmed. Also, in this method, the secret information appears due to the fluorescent color generated by the irradiation of the ultraviolet light during the information processing, so that the information may not be clear and may be difficult to visually recognize, or the erroneous reading may occur even with the machine reading. is there.

On the other hand, even in a method using a conventional concealing label having high visibility and excellent concealing property, the label can be easily peeled off since a weak adhesive is used for the bonding means, and any special equipment can be used. Not only is it easy to read the secret information without requiring it, but also if it is pasted again, there is no trace of the secret information, and the leakage of the secret information cannot be confirmed. Further, in this method, the copied secret information is obtained by a general copying means for copying forms, that is,
This is a copying method combining color former microcapsules and a developer, that is, a so-called carbonless copying method.In this method, low-density coloring or deterioration of coloring over time occurs, and the information may become unclear. is there.

Therefore, the present invention is capable of clearly copying the secret information written on the upper sheet to the lower sheet, securely concealing the copied secret information, and, when the label is peeled off during transportation, It is an object of the present invention to provide a sheet set with a label for concealment of copying, in which the trace is left to prevent the leakage of the information, and at the time of information processing, the information is clearly visible.

[0007]

SUMMARY OF THE INVENTION In view of the above problems, the present inventors releasably quasi-adher a non-transparent concealing sheet and a transparent label substrate, and furthermore, apply a pressure-sensitive adhesive layer to the label. The present inventors have found that the above object can be suitably achieved by pseudo-adhering a copy concealing label formed of a carbon transfer agent on the exposed surface side of the release sheet to be protected to the upper sheet on the concealment sheet side in a peelable manner. Invented the invention.

[0008] That is, the sheet set with a label for copy concealment of the present invention is composed of an upper sheet and a lower sheet, and a concealable sheet which cannot be seen through a predetermined pseudo-adhesive means is peeled off at a predetermined portion on the back side of the upper sheet. And a transparent base material is peelably joined to the lower surface side of the concealing sheet by a second pseudo-adhesion means, and an adhesive is provided on the lower surface side of the transparent base material. A layer is provided, the pressure-sensitive adhesive layer is protected by a release sheet, and a carbon transfer agent is applied to the exposed surface side of the release sheet.

According to the sheet set with the label for concealing copy having such a configuration, since the copy is performed using the carbon transfer agent applied to the surface of the release sheet, the color density is higher than that of the carbonless copy method, and the color is deteriorated with time. Because there is almost no secret information, confidential information can be clearly copied. Also, if the release sheet is peeled off and adhered to the secret information copying section with the exposed adhesive, the secret information can be securely concealed by the opaque opaque sheet and the opaque opaque sheet cannot be seen during information processing. When peeled from a possible label substrate, the information can be clearly recognized through the transparent label substrate. Furthermore, if the concealing sheet is peeled off from the label base material even during transport, even if the concealing sheet is slightly peeled off, it cannot be returned to the original state, and traces thereof remain.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings. Here, FIG. 1 is a cross-sectional explanatory view of a sheet set with a label for copy concealment according to an embodiment of the present invention, and FIG. 2 is a cross-sectional explanatory view of a sheet set with a label for copy concealment according to another embodiment of the present invention. FIG. 3 is a view for explaining an example of use of the sheet set with a label for copy concealment of FIG.

As shown in FIG. 1, a sheet set 1 with a label for copying concealment according to the present embodiment includes an upper sheet a and a lower sheet b connected to each other via a cut-out sewing line d. The concealing sheet 3 which cannot be seen through the first pseudo bonding means 7a is peelably bonded to the back side of the personal identification number entry section n, and the second quasi bonding means 7b is mounted on the lower surface side of the concealing sheet 3. The see-through label substrate 2 is peelably joined, and further, an adhesive layer 4 is provided on the lower surface side of the see-through label substrate 2, and the adhesive layer 4 is protected by a release sheet 5. , The release sheet 5
Is provided with a carbon transfer agent 6 on the exposed surface side.

Here, the pseudo bonding means in the present invention will be described. The pseudo-adhesion means is, for example, applied to each of the opposing surfaces to which a pressure-sensitive adhesive which does not exhibit adhesiveness in a normal state but exhibits adhesiveness by pressing is applied, and is pressed in a state in which both surfaces are opposed to each other. A method of bonding, or a method of applying a weak adhesive between the opposing surfaces to be bonded and pseudo-adhering both surfaces may be used, but it is particularly preferable that one synthetic resin film and a synthetic resin film having low adhesiveness to each other are used. A method of applying the same synthetic resin in a molten state, bonding one synthetic resin film to the other synthetic resin film with the synthetic resin in the molten state, and pseudo-adhering when the synthetic resin in the molten state is solidified. According to this method, once the pseudo-bonded synthetic resin films are once peeled, they cannot be returned to the original state. As the combination of the synthetic resin film in the present invention, for example, polyethylene terephthalate and polyethylene, polypropylene and polyethylene, polybutylene terephthalate and polyethylene, polyethylene terephthalate and polypropylene, polybutylene terephthalate and polypropylene, and the like, olefin-based resin and ester-based Combinations with resins are preferred.

In the case of this embodiment, the first pseudo bonding means 7a
In the normal state, a pressure-sensitive adhesive which does not show adhesiveness in a normal state but shows adhesiveness when pressed is applied to the password entry portion n of the upper sheet a and the upper surface side of the opaque sheet 3 which cannot be seen through, and pressed. Thereby, the concealing sheet 3 and the upper sheet a are releasably joined. On the other hand, as the second pseudo-adhesion means 7b, the transparent base material 2 is made of polyethylene terephthalate, while the non-visible concealing sheet 3 is made of polyethylene, and a polyethylene in a molten state is applied between the two. Are peelably joined.

Next, an example of use of the sheet set 1 with a label for copy concealment of this embodiment will be described. FIG. 3 shows a "bank account opening application form" in which the upper sheet a and the lower sheet b are connected to the sheet set 1 with the label for copy concealment of the present embodiment via the cut-out sewing line d. It is configured as First, as shown in (a), when the applicant writes his / her personal identification number in the personal identification number entry part n of the upper sheet a, the personal identification number is copied to the personal identification number copying part m with the carbon transfer agent 6.

Next, as shown in (b), the release sheet 5 is peeled to expose the pressure-sensitive adhesive layer 4, and this is used to identify the password of the lower sheet b separated from the upper sheet a by the cut-out sewing line d. A pseudo-adhesive see-through label substrate 2 and a non-see-through concealing sheet 3 are attached to the copy section m. In this state, the personal identification number copied to the personal identification number copying section m is completely concealed by the concealing sheet 3 which cannot be seen. And
As shown in (c), after the lower sheet b is transferred, the person in charge checks the password, and when performing information processing, peels off the non-transparent concealing sheet 3 from the translucent label base material 2 to allow the transparent sheet. The personal identification number copied to the personal identification number copy unit m through the appropriate label base material 2 is confirmed.

In the copy-concealing label of the present invention, the adhesive force of the pressure-sensitive adhesive layer provided on the lower surface side of the transparent label substrate is determined by the adhesive force of the first pseudo-adhesive means and the second pseudo-adhesive means. And the adhesive force of the first pseudo-adhesion means must be greater than the adhesive force of the second pseudo-adhesion means, and a non-transparent concealing sheet extends from the copy-concealing label body. It is preferable that the extended portion be hooked with a finger, since the concealing sheet is easily peeled off from the label substrate.

Further, another embodiment of the present invention will be described. As shown in FIG. 2, the sheet set 11 with a label for copying concealment of the present embodiment is configured such that an upper sheet a and a lower sheet b are separated from each other, and their ends are detachably adhered. The other configuration is the same as that of the above-described embodiment. As described above, the present invention is not limited to the method of joining the upper sheet and the lower sheet constituting the sheet set, and even if there is a concept of the relative positional relationship between the upper sheet and the lower sheet, even if the number of sheets is large. I do not care.

[0018]

As described above, according to the sheet set with the label for concealing copy of the present invention, since the copy is performed using the carbon transfer agent applied to the surface of the release sheet, the color density is higher than that of the carbonless copy method. And secret information can be clearly copied because there is almost no deterioration in color development over time. In addition, the confidential information can be securely concealed by the non-transparent concealing sheet, and at the time of information processing, the non-transparent concealing sheet can be peeled off from the transparent label substrate to pass through the transparent label substrate. The information is clearly visible. Furthermore, if the concealing sheet is peeled off from the label base material even during the transfer, it cannot be returned to the original state, and the trace remains, so that the effect of preventing information leakage can be achieved.
