Description

  The present invention relates to a personal information protection sheet in which personal information once in an unreadable state cannot be restored, and the manufacturing cost is low.

  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, since the information printed on the label remains in the fragments, the personal information can be restored to a legible state by connecting the fragments.
In addition, it is necessary to provide a release layer over the entire surface of the label in order to release the base material. However, since the area where the personal information is printed is only a part of the label, the release agent is wasted and costs are increased. It will lead to up.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a personal information protection sheet that cannot be restored and that can be manufactured at low cost.

  In order to achieve the above object, the present invention provides, as a first aspect, a base material, a release layer formed in a predetermined pattern shape on at least a part of one surface of the base material, The personal information protection sheet is characterized by having an image receiving layer laminated on the substrate.

  In the first aspect of the present invention, it is preferable that an information display section showing information related to a specific individual is provided by printing so that at least a part is formed on the image receiving layer.

  Moreover, in order to achieve the said objective, this invention has a base material and the peeling layer formed in the predetermined pattern shape in the at least one part area | region of one side of a base material as a 2nd aspect. The personal information protection sheet characterized by the above is provided.

  In the 2nd aspect of this invention, it is preferable that the information display part which shows the information relevant to a specific individual is provided by printing so that at least one part may be formed on the said peeling layer.

  According to the present invention, it is possible to provide a personal information protection sheet that can be manufactured at low cost, since personal information that has been once unreadable cannot be restored.

First, the outline of the present invention will be described with reference to FIG.
As shown in FIG. 1A, the personal information protection sheet of the present invention has a release layer 20 on one surface of a base material 10 (paper, envelope, postcard, label mount, etc.) for displaying personal information. As a surface-inert energy ray curable resin layer, and the image receiving layer 30 is a sheet in which a resin layer having a low cohesive force is laminated in order. 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 surface of the substrate 10 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 above, the personal information displayed on the surface of the image receiving layer 30 can be peeled off together by rubbing the image receiving layer 30 with a coin or a nail. Thereby, leakage of personal information from the discarded personal information protection sheet can be prevented.

  Further, as shown in FIG. 1B, only the surface-inactive energy ray curable resin layer may be formed as the release layer 20 on one surface of the substrate 10. 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 is taken as an example, but the same effect can be obtained even in a configuration without the image receiving layer 30.
Moreover, although the case where the personal information is already displayed as the information display unit 40 on the image receiving layer 30 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 display arbitrary information 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.

  Further, by providing an adhesive layer (not shown) under the base material 10, it can be attached as a label to another medium (such as an envelope).

[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 (characteristic that the viscosity decreases when stress is applied), and the property as a colored 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. On the other hand, the information display unit 40 formed on the base material 10 does not peel off even if it is rubbed with a coin or a nail.

As shown in FIG. 3 (a), the image receiving layer 30 (the release layer 20 in the case of a configuration without the image receiving layer) is formed in an arbitrary pattern shape, so that the receiving layer 30 and the release layer 20 are formed. The amount of material required is less than when they are solid-printed.
When the image receiving layer 30 is shaved with coins or nails, the information display unit 40 is removed along the pattern shape of the image receiving layer 30 as shown in FIG. 3B, but the information display unit 40 is not completely removed. However, the personal information becomes unreadable. However, even if the pattern shape is arbitrary, if the pattern is too large, the information display unit 40 may remain readable. Therefore, the design of the pattern shape is determined in consideration of the size of the information display unit 40. There is a need to.

  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 all of the image receiving layer 30, so that shavings can be minimized. In addition, as shown in FIG.4 (c), you may form the image receiving layer 20 and the peeling layer 20 so that only a part of personal information displayed by the information display part 40 may become unreadable. For example, it is difficult to specify an individual from the prefectural name part of the address or the area code part of the phone number, so these parts (parts of personal information that are common to an unspecified number of people) May or may not be illegible.

  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 it is peeled off, and therefore 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 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.
In addition, since it is impossible to restore personal information from the image receiving layer 30 scraped from the release layer 20, there is no risk of personal information leaking.
Furthermore, since the material for forming the image receiving layer 30 and the release layer 20 is small, it can be manufactured at low cost.
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.

Here, the case where both the peeling layer 20 and the image receiving layer 30 are formed in an arbitrary pattern shape is taken as an example. However, as shown in FIG. 6A, only the peeling layer 20 has an arbitrary pattern shape. Thus, the image receiving layer 30 may be formed on the entire surface. In this case, by rubbing the image receiving layer 30 with a coin or the like, as shown in FIG. 6B, the image receiving layer 30 is peeled only at a portion overlapping the peeling layer 20, and the information display unit 40 is dropped off. To do.
It goes without saying that the same effect can be obtained even with such a configuration.

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. (A) is a figure which shows the image receiving layer formed in the pattern shape, and the information display part formed on it, (b) is a figure which shows the state which shaved off the image receiving layer. (A) is the figure which showed the personal information protection sheet on which personal information was printed. (B) is the figure which showed the state which peeled and removed personal information. It is a figure which shows the state which provided the display which shows that an image receiving layer is peelable in the personal information protection sheet. It is a figure which shows the structure which made the personal information protection sheet which formed only the peeling layer in the pattern shape, and the state which made the personal information formed in this unreadable.
