Description

  The present invention relates to a personal information protection sheet in which information that is not preferably in an unreadable state is displayed together with personal information, and the personal information once in an unreadable state cannot be restored.

  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 the personal information or the entire postal item must be broken by hand. Or had to be cut with scissors or a shredder. 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 a destination label (a label on which a delivery address and a recipient's name are written) affixed to a bag made of a resin film containing printed matter. In the case of such postal matter, the destination label must be peeled off from the resin film because the destination label cannot be torn into pieces by hand or cut with scissors or a shredder due to separation problems. However, dropping off the destination label can cause a postal accident, so the destination label is generally firmly attached to the resin film. For this reason, it is not easy to peel off the destination label from the bag made of resin film.

As a prior art aimed at solving such a problem, there is a “label displaying personal information” disclosed in Patent Document 1. The invention disclosed in Patent Document 1 is formed with a slit for dividing a display area of personal information into a plurality of parts.
JP 2001-175175 A

In the invention disclosed in Patent Document 1, the base material on the surface of the label is peeled over the entire surface and fragmented. Therefore, information that is not preferable to be unreadable cannot be described on the label together with personal information.
Furthermore, in the invention disclosed in Patent Document 1, the information printed on the label remains as it is even if the base material is fragmented, so that personal information can be restored to a legible state by joining the base material fragments together. .

  The present invention has been made in view of such a problem, and displays a personal information protection sheet that displays undesired information together with personal information together with personal information and that cannot be restored once the personal information has been made unreadable. The purpose is to provide.

  In order to achieve the above object, the present invention provides, as a first aspect, a base material, a release layer formed on a part of one surface of the base material, an image receiving layer laminated on the release layer, A personal information display unit that displays information related to a specific individual formed by printing on the image receiving layer, and the information that the personal information display unit displays in the area where the release layer is not formed on the substrate; The personal information protection sheet is characterized in that the associated information is displayed.

  Moreover, in order to achieve the said objective, this invention is formed by printing on a base material, the peeling layer formed in a part of one surface of the base material, and a peeling layer as a 2nd aspect. A personal information display unit indicating information related to a specific individual, and information associated with the information indicated by the personal information display unit is displayed in an area where the release layer is not formed on the base material. The personal information protection sheet characterized by the above is provided.

  In the first aspect or the second aspect of the present invention, the information associated with the information indicated by the personal information display unit is preferably encrypted.

  ADVANTAGE OF THE INVENTION According to this invention, the personal information protection sheet which can restore | restore the personal information once made into an unreadable state only as needed by the person who gave personal information can be provided.

First, the outline of the present invention will be described with reference to FIG.
The personal information protection sheet of the present invention is an energy ray-curable resin that is surface-inactive as a release layer 20 on one surface of a substrate 10 (paper, envelope, postcard, label mount, etc.) for displaying personal information. This is a sheet in which a resin layer having a low cohesive force is sequentially laminated as a layer and an image receiving layer 30. The image receiving layer 30 has low adhesion to the release layer 20, and is peeled off from the interface with the release layer 20 when a force substantially parallel to the substrate is locally applied (rubbed with a coin or a nail). Address, name, and telephone number that become personal information by the information display unit 40 formed on the surface of the image receiving layer 30 by a known printing method (formation by a printer with ink, toner, or by handwriting with printing or pencil). In the personal information protection sheet displaying the information as the information display unit 40, the personal information (information display unit 40) displayed on the surface of the image receiving layer 30 is peeled off together by rubbing the image receiving layer 30 with coins, nails or the like. be able to. Thereby, leakage of personal information from the discarded personal information protection sheet can be prevented.

  Moreover, as shown in FIG.1 (b), you may form only the surface-inactive energy-beam curable resin layer as the peeling layer 20 in one surface of the base material 10. FIG. In this case, the personal information (information display unit 40) formed on the release layer 20 can be released by rubbing the release layer 20 with coins or nails.

In the following embodiments, a configuration including the image receiving layer 30 will be described as an example. However, the same effect can be obtained even in a configuration without the image receiving layer 30.
Moreover, although the case where personal information is printed on the image receiving layer 30 as the information display unit 40 is taken as an example, the information display unit 40 may be in an unformed state. In this case, it goes without saying that the user can print information related to the nonvolatile information 100 on the print information protection sheet as the information display unit 40 by a known printing method.

Embodiment
Next, an embodiment of the present invention will be described with reference to the drawings.
Fig.1 (a) is the figure which showed the cross section of the personal information protection sheet concerning this embodiment.
As shown in FIG. 1A, the personal information protection sheet includes a base material 10, a release layer 20, and an image receiving layer 30, and the release layer 20 and the image receiving layer 30 are arranged in this order on one surface of the base material 10. Are stacked. On the image receiving layer 30, personal information is displayed by an information display unit 40 formed by a known printing method. On the base material 10, the peeling layer 20 and the image receiving layer 30 are laminated by a technique such as offset printing, screen printing, gravure printing, flexographic printing, etc., but if these layers do not need to be formed to be particularly thick, the cost is reduced. From the side, offset printing and flexographic printing are preferable.

[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.
Moreover, it can also be used as a label by providing an adhesive layer (not shown) under the substrate 10.

[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.

  The release layer 20 is formed by curing a mixture comprising a monomer, a synthetic resin, a reaction initiator, and a release agent. 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.

[Image receiving layer]
The image receiving layer 30 uses an ultraviolet curable resin or the like. The image receiving layer 30 is formed by curing a mixture of a pigment, a synthetic resin, a reaction initiator, and a release agent. Note that the image receiving layer 30 may or may not contain a pigment. If not, the content of other composition materials increases.
The pigment has properties as an extender pigment and a color pigment. The property as an extender is to give the binder material thixotropy (the viscosity decreases when stress is applied), and the property as a coloring pigment is to color the binder material. An example of the color pigment is titanium white. The monomer is used as a reactive diluent and serves to adjust the viscosity. Synthetic resins are the main component of the resin component constituting the image receiving layer. The reaction initiator is for accelerating the curing (drying) reaction of the mixture, and the release agent is for imparting release characteristics to the image receiving layer 30.

  The personal information protection sheet according to the present embodiment can be printed regardless of the thickness of the image receiving layer 30. Further, the image receiving layer 30 cannot be peeled from the release layer 20 unless the image receiving layer 30 has a certain thickness. A thicker image receiving layer 30 (1 μm or more) has better friction resistance, but even when the image receiving layer 30 is thin (0.5 μm or less), the friction resistance is improved due to the influence of the substrate 10.

  In addition, the personal information protection sheet may be subjected to unnecessary friction during use (such as during mailing), but the image receiving layer 30 and the information display unit 40 are subject to such friction. In addition, friction resistance is required so as not to inadvertently peel off the release layer 20.

FIG. 2 is a diagram showing a state in which the image receiving layer 30 is scraped off from the release layer 20.
As shown in FIG. 2, the image receiving layer 30 is formed on the image receiving layer 30 by scraping the image receiving layer 30 with coins, nails or the like (in other words, by rubbing the image receiving layer 30 while applying a pressure of a predetermined value or more). The information display unit 40 is also peeled off and removed from the peeling layer 20 at the same time. The adhesion between the image receiving layer 30 and the release layer 20 can be adjusted by the composition of the mixture that forms the respective bases of the release layer 20 and the image receiving layer 30.

  As shown in FIG. 3, in the personal information protection sheet according to the present embodiment, the image receiving layer 30 (the peeling layer 20 in the case of a configuration without this) is formed only on a part of the substrate 10. And the non-volatile information 100 is displayed in the part in which the peeling layer layer 20 is not formed. The content of the nonvolatile information 100 is arbitrary, but is preferably information related to the personal information displayed by the information display unit 40. For example, when a user's address and name are described as personal information, if the user ID of the user is displayed as non-volatile information 100, even if the personal information is damaged for some reason, the personal information Can be specified based on the non-volatile information 100.

  When the personal information protection sheet is used as a postcard or as a destination label to be affixed to an envelope or a parcel, the protective layer 30 is rubbed in contact with other mailed items during mailing, and the information display unit 40 Personal information (destination information) to be displayed may be unreadable. Even in such a case, the personal information can be restored by displaying the information related to the information display unit 40 as the nonvolatile information 100 as described above. Therefore, the personal information protection sheet according to the present embodiment can be particularly preferably used as a postcard or address label.

  Since the non-volatile information 100 does not become unreadable unless it is painted or the personal information protection sheet itself is cut, it is preferably displayed in an encrypted state by an arbitrary method. In particular, if the non-volatile information 100 is information related to personal information, the non-volatile information 100 is displayed in an encrypted state (for example, displayed as a barcode). It becomes difficult to guess information, and leakage of personal information can be prevented.

  Normally, as shown in FIG. 4A, personal information such as an address and a name is often printed only on a part of the personal information protection sheet. The location where the layer 30 is scraped is only the address and name as shown in FIG. Unlike conventional so-called “scratch cards”, it is not necessary to scrape off all of the image receiving layer 30, so that shavings can be minimized.

  Note that the personal information protection sheet according to the present embodiment makes it difficult for the user to recognize that the image receiving layer 30 can be peeled from the release layer 20 only by the appearance. Therefore, as shown in FIG. In order to notify the user that the release layer 20 can be peeled off, it is preferable to display it as an attention display unit 50 at an arbitrary position on the personal information protection sheet. However, if the display position is on the release layer 20, the portion may be peeled off. Therefore, the fact that the image receiving layer 30 can be peeled from the release layer 20 means that the release layer 20 is not formed. It is preferable to display in the area. If the release layer 20 or the image receiving layer 30 is formed by printing colored ink, it is possible to reduce the man-hour that the image receiving layer 30 can be peeled from the release layer 20 if they are simultaneously formed by printing when forming them. Can be displayed without increasing. The display format of the alert display unit 50 is not limited as long as it allows the user to recognize that the image receiving layer 30 can be peeled off, such as characters and patterns (for example, an image diagram cut with a coin).

  In the personal information protection sheet according to the present embodiment formed as described above, even if the image receiving layer 30 is rubbed with a small surface pressure (for example, rubbed with a finger belly or an eraser), the rubbed part is the release layer 20. Is not peeled off, but when rubbed with a large surface pressure (for example, rubbed with a coin or a nail), the rubbed portion peels off from the release layer 20.

  Even when an adhesive tape is attached to the image receiving layer 30, the force does not concentrate locally on the image receiving layer 30 when the adhesive tape is peeled off, so the image receiving layer 30 does not peel off. The conventional so-called “scratch card” takes into account that the concealing layer (silver layer) is peeled off when the adhesive tape is applied to the surface and peeled off, the image receiving layer 30 and the peeling layer 20 in the personal information protection sheet according to this embodiment. Can be said to be higher than the concealing layer of the conventional scratch card.

  Therefore, even when the personal information protection sheet according to the present embodiment is applied to a postal matter or the like, the image receiving layer 30 is rubbed during transportation, and the personal information is not readable and a postal accident does not occur.

In the personal information protection sheet according to the present embodiment, the image receiving layer 30 is peeled off and removed from the release layer 20 by rubbing the image receiving layer 30 while applying a pressure equal to or higher than a predetermined value. When personal information is displayed on the display unit 40, it is peeled off and removed at the same time. Therefore, when the personal information protection sheet on which the personal information is printed 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.
In addition, since the non-volatile information 100 is not illegible, if information related to the personal information is displayed as the non-volatile information 100, even if the personal information becomes illegible, the contents can be specified. Is possible.
In addition, since it is impossible to restore personal information from the image receiving layer 30 that has been scraped off from the release layer 20, there is no possibility of personal information leaking from the scraped residue.
Furthermore, when used as a label, it is not necessary to peel the entire label when making personal information unreadable, so that it can be attached to a member to be attached with sufficient adhesive strength. In addition, when making personal information unreadable, the entire label or part of the surface layer will not be peeled off, so the label (or part of it) that has not made the personal information unreadable is dropped. There is no risk of personal information leaking from now on.

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 sheet in which personal information is displayed on the image receiving layer 30 by the information display unit 40 is taken as an example, but the information displayed by the information display unit 40 is limited to personal information. It may represent any character, sentence, or design. In the case of a configuration including an image receiving layer, the release layer and the image receiving layer are not necessarily formed with the same size (area). That is, the image receiving layer may be laminated only on a part of the peeling layer, or a part of the image receiving layer may protrude from a region where the peeling layer is not formed.
As described above, the present invention can be variously modified.

It is the figure which showed the structure of the personal information protection sheet concerning suitable embodiment of this invention. It is the figure which showed a mode that the image receiving layer was peeled and removed. It is a figure which shows non-volatile information. (A) is the figure which showed the personal information protection sheet on which personal information was printed.
