Description

The present invention relates to a personal information protection label provided with a layer capable of removing the described personal information.

  Conventionally, when discarding postal items with personal information such as address and address, to prevent leakage of personal information from the waste, the portion containing personal information or the entire postal item has been manually broken. There was a problem of having to cut with scissors and shredders. In particular, finely fragmenting by hand (by hand or scissors) to such an extent that personal information cannot be specified is extremely laborious.

  In addition, some mail items have an address label (a label on which a delivery address and a recipient's name are written) attached to a bag made of a resin film containing printed materials. In the case of such mail, the address label must be peeled off from the resin film because the resin film cannot be torn apart by hand or the address label cannot be cut with scissors or a shredder. However, since the drop off of the address label can cause a mail accident, the address label is generally firmly attached to the resin film. For this reason, it is not easy to peel off the address label from the resin film bag.

In order to solve the above problem, in the invention described in Patent Document 1, a paper having a protection information description area for describing personal information is provided on the periphery of the protection information description area. Separation lines for separating from other parts are provided, and further, chopping lines for cutting the protection information description area into a plurality of pieces are provided. As a result, the protection information description area is cut off from other portions of the paper and cut according to the cutting line, whereby the protection information description area is cut into a plurality of pieces to enable fragmentation.
JP 2004-317875 A

  However, in the invention described in Patent Document 1, it is difficult to separate the protection information description area from other parts of the paper according to the separation line (not necessarily separated along the separation line), There is a possibility of damaging the part. In addition, fragmenting the protection information description area into multiple pieces to the extent that personal information cannot be specified according to the broken line is not much different from the conventional work of fragmenting the part where the personal information is described with hands or scissors, Annoying is no different.

The present invention has been made in view of such problems, and an object of the present invention is to provide a personal information protection label that can easily make personal information unreadable.

In order to achieve the above object, the personal information protection label according to the first aspect of the present invention is formed on the base material and at least a part of the surface of the base material, and the information display portion formed thereon is peeled off. A personal information protection label having a peelable layer, which is provided on the surface of the substrate opposite to the surface on which the release layer is formed, and is on the surface opposite to the surface in contact with the substrate. It has the adhesion layer provided with .

  In this invention, it is preferable that a peeling layer is formed with the thickness more than the average arithmetic roughness of the surface of a base material.

In any of the above configurations, it is more preferable that the base material has a cut. In addition, it is preferable that the information display unit has a warning display unit that displays that the peelable layer can be peeled from the release layer. In addition, the warning display unit has no release layer formed on the substrate. More preferably, it is provided in the region. Moreover, it is preferable that the information which shows the information relevant to an individual is formed as an information display part, and in addition to this, it is more preferable to provide the protective layer which consists of a transparent material in the uppermost layer.

ADVANTAGE OF THE INVENTION According to this invention, the personal information protection label which can make the printed personal information into an unreadable state can be provided.

First, the outline of the present invention will be described with reference to FIG.
In the personal information protection label of the present invention, a surface-inactive energy ray curable resin layer is formed as a release layer 20 on a substrate 10. Personal information (address or name) is formed on the surface of the release layer 20 by an information display unit 30 formed by a known printing method (formation with a printer using ink, toner, printing, handwriting with a pencil, etc.). In the personal information protection label displaying the telephone number, etc., the formed personal information (information display unit 40) formed on the release layer 20 is peeled off by rubbing the release layer 20 with coins or nails. Can do. Thereby, when discarding the postcard or the envelope as the base material, it is possible to prevent the leakage of the personal information by peeling off and removing the information display unit 30 that displays the personal information.

In the following description, the information display unit 30 that displays personal information is formed on the release layer 20 as an example, but the information display unit 30 may be in an unformed state. In this case, it goes without saying that the user can display arbitrary information by forming the information display unit 30 on the personal information protection label by a known printing method.

[First Embodiment]
Next, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing a cross section of the personal information protection label according to the present embodiment.
As shown in FIG. 1, the personal information protection label includes a base material 10 and a release layer 20 for describing personal information such as paper, envelopes, postcards, and label mounts. On the release layer 20, personal information is displayed by an information display unit 30 formed by a Kochi printing method. The release layer 20 is formed on the substrate 10 by a technique such as offset printing, screen printing, gravure printing, flexographic printing, etc. However, if it is not necessary to form the release layer 20 to be particularly thick, offset printing is performed from the cost aspect. Flexographic printing is preferred.

[Base material]
The base material 10 can be appropriately selected from known materials. For example, paper (quality paper, coated paper, kraft paper, etc.), polyester film (polyethylene terephthalate, polyethylene terephthalate / isophthalate copolymer, etc.), polyolefin film (polyethylene, polypropylene, polymethylpentene, etc.), plastic film (polychlorinated) Vinyl film, ethylene vinyl alcohol copolymer film, polycarbonate film, polyamide film, etc.) and synthetic paper made of polyolefin.
Further, by providing an adhesive layer (not shown) under the base material 10, it is possible to adhere to another medium (envelope or the like). In this case, it can also be used as a label by providing a release paper under the adhesive layer to have a layer configuration of release layer / base material / adhesive layer / release paper. When used as a label, as shown in FIG. 2, it is preferable to provide a notch 10a in the substrate 10 to lower the mechanical strength (to make it a brittle substrate). If such an incision is provided, the personal information protection label is broken from the incision 10a even if the entire personal information protection label affixed to the adherend member is peeled off. Thereby, the leakage of personal information due to peeling off of the personal information protection label can be prevented.

[Peeling layer]
The release layer 20 uses an ultraviolet curable resin such as urethane acrylate or epoxy acrylate, or an electron beam curable resin. Other materials include solvent-type thermoplastic resins (vinyl chloride / vinyl acetate copolymer resins, acrylate / styrene copolymer resins, nitrocellulose, maleic acid resins, etc.), water-soluble resins (polyvinyl alcohol, polyvinyl acetate, etc.). Pyropidone etc.), various acrylic copolymer resins, polyurethanes, etc. can be used alone, or a release agent such as silicon resin can be added to these.

In addition, the composition of the mixture that is the basis of the release layer 20 is as shown in Table 1, and the content of each material can be changed as appropriate when the total content is 100%.
The purpose of using each material is as follows.
The monomer serves as a reactive diluent and serves to adjust the viscosity of the mixture. The synthetic resin is a main component of the resin component constituting the release layer 20. The initiator promotes the curing (drying) reaction of the mixture. The release agent gives the release layer 20 release properties. The coloring pigment is used when coloring the release layer 20.

Also, personal information protection label postcard or paper envelope or film envelope, when used as a label board, but part of the label mailing or the like in some cases subjected to unnecessary friction, the information display unit 30, thus Even if it receives excessive friction, it needs to have friction resistance so that it will not be inadvertently separated from the release layer 20.

As shown in FIG. 3, the information display unit 30 formed on the surface of the release layer 20 is scraped with a coin, a nail or the like (in other words, the information display unit 30 is rubbed while applying a pressure of a predetermined value or more. The information processing unit 30 is peeled off and removed from the peeling layer 20. In addition, the adhesiveness between the information processing unit 30 and the release layer 20 can be adjusted by the composition of the mixture that is the basis of the release layer 20.
Further, unlike the scratch card, it is not necessary to remove all the concealed portions, and only the printed ink portions are removed, so that scraps can be minimized.

In addition, since the personal information protection label according to the present embodiment cannot recognize that the information display unit 30 can be peeled from the peeling layer 20 only by the appearance, the information display unit 30 is peeled off from the peeling layer 20 as shown in FIG. In order to inform the user that it can be peeled off, it is preferable to display it at an arbitrary position on the personal information protection label as the attention display section 60. However, in the case of display by printing, since the display itself may be peeled off when the display position is on the peeling layer 20, it is preferable to display on the part where the substrate 10 is exposed. . If the release layer 20 is formed by printing colored ink, the information display unit 30 can be peeled from the release layer 20 without increasing the number of steps if it is simultaneously formed by printing when forming the release layer 20. Can be displayed. Further, the information display unit 30 may be formed at the same time. Note that the display format of the alert display unit 60 is not limited as long as it allows the user to recognize that the information display unit 30 can be peeled off, such as a character or a pattern (for example, an image figure cut with a coin).

In the personal information protection label according to this embodiment formed as described above, even if the information display unit 30 is rubbed lightly (for example, rubbed with a finger belly or an eraser), the rubbed portion is removed from the release layer 20. Although it does not peel off, if it is rubbed while applying a pressure equal to or higher than a predetermined value (for example, when rubbed with a coin or a nail), the rubbed part peels off from the release layer 20.

Further, even when an adhesive tape is attached to the information display unit 30, the information display unit 30 does not peel off because the force does not concentrate locally on the information display unit 30 when the adhesive tape is peeled off. . In view of the fact that the concealing layer (silver layer) is peeled off when the conventional so-called “scratch card” is peeled off with an adhesive tape applied to the surface, the information display unit 30 and the peeling layer in the personal information protection label according to this embodiment It can be said that the adhesiveness to 20 is preferably higher than the concealment layer of the conventional scratch card.

Therefore, even when the personal information protection label according to the present embodiment is applied to a postal item or the like, the information display unit 30 is rubbed during transportation, so that the personal information cannot be read and a postal accident does not occur.

In the personal information protection label according to this embodiment, the information display unit 30 is peeled off and removed from the release layer 20 by rubbing the information display unit 30 while applying a pressure of a predetermined value or more. Therefore, when the personal information protection label on which the personal information is displayed is discarded, the personal information can be made unreadable by a simple operation, and leakage of the personal information from the waste can be prevented.

[Second Embodiment]
A second embodiment in which the present invention is suitably implemented will be described.
The configuration of the personal information protection label according to the present embodiment is the same as that of the first embodiment. The release layer 20 is formed on the substrate 10 and the information display unit 30 formed on the release layer 20 is formed. In this configuration, personal information is displayed.
However, in the present embodiment, the release layer 20 is formed with a thickness equal to or greater than the arithmetic average roughness (Ra) of the surface of the substrate 10.
The arithmetic average roughness (Ra) is extracted from the roughness curve by the reference length L in the direction of the average line (x direction), and from the average line of the extracted portion to the measurement curve y = f (x). The absolute values of deviations (y direction deviations) are summed and averaged, and can be calculated by equation (1). Arithmetic mean roughness (Ra) has the property that the influence of a single scratch on the measured value becomes very small and a stable result can be obtained.

  Table 2 shows the arithmetic average roughness of the surface of the substrate 10 and the arithmetic average roughness of the release layer 20 formed thereon. In Table 2, the surface roughness of “quality paper” is the value of the trade name “NPi Form 55” manufactured by Nippon Paper Industries Co., Ltd. The surface roughness of “matt coated paper” is the value of the trade name “alpha matte” manufactured by Hokuetsu Paper Co., Ltd. Furthermore, the surface roughness of “Gloss Coated Paper” is the value of the product name “Full Color Foam (G) 55” manufactured by Nippon Paper Industries Co., Ltd.

  Whatever material is used, the surface of the substrate 10 has irregularities (for example, if the substrate 10 is paper, there are irregularities due to fibers), but generally the adhesion between the two layers in the laminated structure is The higher the surface roughness of the interface, the higher. Further, in order to peel off the information display unit 30 when a force whose direction component parallel to the surface of the base material is stronger than a predetermined strength acts on the surface, it is necessary that the base layer contains a release agent. There is.

For this reason, if the surface roughness of the peeling layer 20 is smaller than the surface roughness of the substrate 10, the leveling (smoothing) effect can be obtained by forming the peeling layer 20 as shown in FIG. As a result, the peelability of the information display unit 30 can be improved.
However, even in such a case, if the thickness of the release layer 20 is not sufficient, the protrusion of the base material 10 protruding from the release layer 20 comes into contact with the information display unit 30 as shown in FIG. The information display unit 30 cannot be provided with sufficient peelability.
Since the personal information protection label according to the present embodiment forms the release layer 20 with a thickness equal to or greater than the arithmetic average roughness of the base material 10, the convex portion of the base material 10 hardly protrudes from the release layer 20. In addition, the peelability between the release layer 20 and the information display unit 30 is good.

For the above reason, even if a material having a surface roughness smaller than that of the release layer 20 (for example, gloss coated paper) is used as the base material 10, if the release layer 20 containing a release agent is not provided, the information display The part 30 cannot be made peelable.
In this case, the surface roughness after the release layer 20 is formed becomes larger than that of the base material itself. Even in such a case, the information display unit 30 can be satisfactorily peeled from the release layer 20. Be held. In addition, in this embodiment, if the arithmetic average roughness after forming the peeling layer 20 is 0.5 to 0.6 μm, good peelability was obtained.

In the personal information protection label according to this embodiment formed as described above, even if the information display unit 30 is rubbed lightly (for example, rubbed with a finger belly or an eraser), the rubbed portion is removed from the release layer 20. Although it does not peel off, if it is rubbed while applying a pressure equal to or higher than a predetermined value (for example, when rubbed with a coin or a nail), the rubbed part peels off from the release layer 20.

  Further, even when an adhesive tape is attached to the information display unit 30, the information display unit 30 does not peel off because the force does not concentrate locally on the information display unit 30 when the adhesive tape is peeled off. .

Therefore, even when the personal information protection label according to the present embodiment is applied to a postal item or the like, the information display unit 30 is rubbed during transportation, so that the personal information cannot be read and a postal accident does not occur.

As in the first embodiment, in the personal information protection label according to this embodiment, the fact that the information display unit 30 can be peeled off from the peeling layer 20 is displayed at an arbitrary position on the personal information protection label. It is preferable. In this case, it is preferable that the display by printing is not performed on the release layer 20 but on the exposed part of the base material 10 because the display is not likely to disappear. Nor.

As in the first embodiment, the personal information protection label according to this embodiment is peeled and removed from the release layer 20 by rubbing the information display unit 30 while applying a pressure of a predetermined value or more. The Therefore, when discarding the personal information protection label on which the personal information is displayed by the information display unit 30 formed on the release layer 20, the personal information can be made unreadable by a simple operation. Leakage of personal information from things can be prevented.

[Third Embodiment]
A third embodiment in which the present invention is preferably implemented will be described. FIG. 6 shows the configuration of the personal information protection label according to this embodiment. This personal information protection label has the same configuration as that of the first embodiment except that the protective layer 40 is provided on the information display unit 30. The protective layer 40 is transparent, and personal information displayed by the information display unit 30 is visible through the protective layer 40.

The protective layer 40 is formed by attaching a plastic film or printing or applying a water-soluble resin or a water-resistant resin. When the plastic film is pasted, the personal information displayed by the information display unit 30 is unreadable by rubbing the information display unit 30 while applying a pressure equal to or higher than a predetermined value after peeling off the protective layer 40. it can. As in the case of the adhesive tape described in the first embodiment, the information display unit 30 does not peel from the release layer 20 together with the protective layer 40 even if the plastic film is peeled off.
In addition, when water-soluble resin is applied, the personal information displayed by the information display unit 30 is read by rubbing the information display unit 30 while applying a pressure higher than a predetermined value after the protective layer 40 is wetted with water. Can be impossible.
In the case of applying a water resistant resin, the personal information displayed by the information display unit 30 is unreadable by rubbing the information display unit 30 while applying a pressure of a predetermined value or more from above the protective layer 40. it can. Note that it is preferable to add a rubbery resin to the water-resistant resin because the scraps of the information processing unit 30 and the protective layer 40 are collected as a lump and do not scatter.

In addition, the said embodiment is an example of suitable implementation of this invention, and this invention is not limited to this. For example, in the above embodiment, the personal information protection label in which personal information is described by the information display unit 30 on the release layer 20 is taken as an example, but the information displayed by the information display unit 30 is limited to personal information. It may represent any character, sentence, or design.
As described above, the present invention can be variously modified.

It is the figure which showed the structure of the personal information protection label in this embodiment. It is a figure showing the base material which formed the notch and reduced the mechanical strength. It is the figure which showed a mode that the ink in this embodiment peeled and removed. It is a figure which shows the state which provided the display which shows that an information display part is peelable on the personal information protection label . It is a figure which shows the state of the interface of a base material and a peeling layer. It is a figure which shows the structure of the personal information protection label concerning 3rd Embodiment which implemented this invention suitably.
