Description

[Detailed Description of the Invention] Industrial Application Field The present invention is concealment information that displays concealment information (hereinafter referred to as concealment information) that should not be disclosed to others such as deposit balance, loan repayment balance, and various personal identification numbers. The present invention relates to a display sheet, and more particularly, to a display sheet that can be peelably adhered to obtain a hidden information carrier in which hidden information is covered and hidden.

2. Description of the Related Art In the past, peelable adhesion in this type of concealed information carrier is such that the covert information display sheet such as a card on which covert information is displayed does not have any special means, and the adhesive provided on the covert sheet such as a label. This is done by adjusting the adhesive strength of the agent.

Therefore, in the conventional art, when the adhesive strength of the pressure-sensitive adhesive provided on the concealment sheet is too strong, the concealment information display surface is also peeled off when peeled from the concealment information display sheet. On the other hand, it becomes impossible to read the information, but if the adhesive strength is too weak, the concealment sheet will peel off from the concealment information display sheet during handling, and it will be impossible to fulfill the function as the concealment information holder. However, there is a problem that it is extremely difficult to adjust the adhesive force of the pressure-sensitive adhesive.

It is an object of the present invention to provide a hidden information display sheet that eliminates such inconvenience.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a surface on which information to be concealed is displayed with an uneven surface on the surface of a pressure-sensitive adhesive applied to a predetermined portion on the back surface of a substrate. The concealing sheet is peelably adhered, whereby the information to be concealed is covered by the concealed information display sheet, and the concealment sheet is adhered along at least one edge of the information display surface to be concealed. An adhesion enhancing layer including microcapsules encapsulating a plasticizer for strengthening is provided. To form the uneven surface of the adhesive, 15-70μ, preferably 30
A spherical pressure-sensitive adhesive having a particle size of ˜50 μm may be used, or a spherical substance such as cornstarch, silica, or titanium oxide having a particle size of about ½ of the pressure-sensitive adhesive coating thickness may be mixed in the pressure-sensitive adhesive. Also, the adhesion enhancing layer is configured such that the quality of the surface is different from the other parts of the sheet surface.

By forming the concavo-convex surface side of the pressure-sensitive adhesive of the concealment sheet, the contact area of the pressure-sensitive adhesive with respect to the surface of the concealment information display sheet becomes small, so that the contact area is adjusted without adjusting the adhesive force of the pressure-sensitive adhesive itself. By adjusting, the adhesive force of the concealment sheet to the concealment information display sheet can be adjusted. Then, even if the adhesive strength is set to be weak enough to be peeled off, the concealment sheet and the concealment information display sheet are firmly adhered to each other in the adhesion enhancing layer, so that the concealment sheet peels from the concealment information display sheet during handling. There is no fear, and the hiding sheet can be peeled off from the hiding information display sheet at least in the portion other than the adhesion enhancing layer.

Embodiment Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a sectional view of a covert information possession card which is a covert information carrier, FIG. 2 is a plan view showing a display card which is a covert information display sheet in a continuous state, and FIG. Fig. 4 is a plan view of a concealing label which is a concealing sheet in a continuous state, and Fig. 5 is a sectional view taken along the line BB.
FIG. 6 is a cross-sectional view of the display card in a single piece state in which the concealment information is displayed, and FIG. 7 is a plan view of the display card with the concealment label peeled off.

As shown in FIG. 1, concealment information such as a deposit balance display 8 and a balance reference date display 9 (see FIG. 7) is previously displayed on the upper surface side of the display card 1 by an appropriate means such as printing,
Adhesion enhancing layers 7a and 7b are provided along a pair of opposite side edges of the display surface. These adhesion enhancing layers 7a, 7b
Is formed by applying microcapsules encapsulating a plasticizer such as dimethyl phthalate or dioctyl phthalate, and the microcapsules are destroyed by the pressing force when the concealment label 10 that is a concealment sheet described below is destroyed and encapsulated. The plasticizer leaches out and enhances the adhesive strength of the spherical pressure-sensitive adhesive 14, which will be described later. And the hidden label 10
However, a spherical adhesive 14 is provided on the back surface side of the display card 1 to cover and cover up the covert information such as the deposit balance display 8 and the balance reference date display 9 (see FIG. 7).
Thus, the concealment information possessing card 20 is constituted by firmly adhering the portions corresponding to the adhesion enhancing layers 7a and 7b, and peelably adhering to the portions other than the portions corresponding to the adhesion enhancing layers 7a and 7b.

The base material 15 of the concealment label 10 as a concealment sheet is a sheet material made of any material such as paper, resin film, and synthetic paper, and has low opacity due to its material, thickness, etc. Is supplemented by printing on the back side or providing an aluminum foil layer. Further, the base material 15 is provided with cutting perforations 13a and 13b along positions corresponding to the insides of the adhesion enhancing layers 7a and 7b. Further, as can be seen in FIG. 4, on the surface of the base material 15, a "deposit balance notice" is displayed at the top and a "please remove from the perforation" display along the bottom side. Arrows from both ends toward the perforations 13a and 13b for cutting are printed in advance.

The spherical adhesive 14 has a particle size of 15 to 70μ, preferably
It has a particle size of 30 to 50 μm and does not form a coating after coating and drying, and can maintain a spherical shape, and is scattered by being held by the binder 12. Then, since the spherical adhesive 14 is scattered and adheres in a dot shape, the adhesive force of the spherical adhesive 14 portion becomes weak so that it can be peeled off even after once adhered, as described above. Further, as the binder 12, acrylic emulsion, SBR latex, natural rubber latex and the like are preferable. If the particle size of the spherical pressure-sensitive adhesive 14 is smaller than 15μ, the pressing force applied at the time of adhesion causes the particles to be crushed and adhered to each other, resulting in a planar adhesive rather than a point-like adhesive, so that the desired effect is obtained. Although not obtained, the particle size
If it is larger than 70 μm, it becomes difficult to hold it with the binder 12. In addition, the coating amount of the spherical adhesive 14 (coating dry weight)
Is preferably about 5 to 10 g / m ² including the binder 12.

Next, the display card 1 and the concealment label 10 in a continuous state used for creating the concealed information possession card 20 will be described.

As shown in FIG. 2, the display card 1 is in a continuous state in which the display card 1 is connected through the folding and cutting perforations 2, and the marginal holes 4 are provided at both ends in the width direction with the cutting perforations 3a and 3b as boundaries.
Marginal portions 5a and 5b in which a and 4b are transparently provided at equal intervals are provided. On one surface of each card 1, there is provided a deposit balance display unit 6 as a concealed information display unit divided into upper and lower three stages, and a display of "notice of deposit balance" is printed in advance on the uppermost stage thereof. As is clear from FIGS. 2 and 3, microcapsules in which plasticizers are encapsulated in a strip shape along the perforations 3a and 3b on the same surface as the deposit balance display portion 6 of each display card 1. Are provided to provide adhesion enhancing layers 7a and 7b.

As shown in FIG. 6, while the display card 1 is transferred in a predetermined direction in a continuous state, the deposit balance display 8 which is concealment information is displayed together with the balance reference date display 9 and the deposit balance is displayed by an appropriate printer linked to a computer. It is printed on the portion 6 (see FIG. 7), and the marginal portions 5a and 5b are cut from the perforating perforations 3a and 3b, respectively, and then cut at the perforating perforations 2 into a single piece.

Next, the concealment label 10 will be described with reference to FIGS. 4 and 5. The concealment label 10 is releasably adhered to the continuous label paper 11 at regular intervals.
It is desirable that the label paper 11 be subjected to a peeling process.
The concealment label 10 is formed so that its size is substantially the same as that of the diced display card 1 described above, and a predetermined display is already printed on the surface thereof in the state shown in FIG. ing.

Therefore, the concealment label 10 peeled from the label paper 11 is separated from the label paper 11 on the deposit balance display surface of the display card 1 which is separated into the state shown in FIG. 6 and in which the deposit balance display 8 and the balance reference date display 9 are printed. When it is adhered by the exposed spherical adhesive 14, it becomes the concealed information possession card 20 shown in FIG. 1, and the display of the concealed information display section 6 including the deposit balance display 8 is covered and hidden, and is invisible from the outside. Becomes

Here, since the display card 1 is provided with the adhesion enhancing layers 7a and 7b formed by applying microcapsules encapsulating a plasticizer, when the hiding label 10 is pressed to adhere to the display card 1, the adhesion enhancing The microcapsules of layers 7a and 7b are destroyed, and the encapsulated plasticizer leaches out,
The adhesive strength of the spherical adhesive 14 will be enhanced. Therefore, the concealment label 10 is adhered to the display card 1 inside the cutting perforations 13a and 13b in a peelable manner, but on the outside in a non-peelable manner. There is no risk that the concealment label 10 and the display card 1 will separate from each other during the handling of the information possession card 20. Then, the concealment label 10 is provided with the perforation perforations 13a and 13b for cutting.
When it is wound up so as to be separated from the cover, as shown in FIG. 7, the concealment label 10 is removed except for both ends, and the concealed deposit balance display 8 and balance reference date display 9 are exposed. Will be visible.

Note that the present invention is not limited to the above-described embodiments, and for example, as a configuration in which the surface side of the pressure-sensitive adhesive is uneven, an ordinary pressure-sensitive adhesive having a strong adhesive force applied to the base material 15 is used. A spherical substance made of corn starch, silica, titanium oxide or the like may be mixed, and the particle size of the spherical substance is preferably about 1/2 of the thickness of the adhesive coating. With this configuration,
The projecting portion of the spherical substance is in a non-adhesive state, and as a result, the adhesive is adhered in a dot shape. Further, the display card 1 and the concealment label 10 may be in a single piece state from the beginning. Further, the display card 1 and the base material 15 may be connected to each other at one edge through a folding portion. Furthermore,
The sizes of the display card 1 and the base material 15 are not limited to the same size. The base material 15 is smaller than the display card 1 and is large enough to cover concealment information such as the deposit balance display 8. If so, the size may be, for example, half or less. Furthermore, the adhesion enhancing layers 7a and 7b may be provided only on one end side. In this case, it is sufficient to provide only one cutting perforation 1a and 13b on the same end side. Furthermore, the base material 15 may be configured to be easily rolled up by providing a protruding piece for hanging a finger on the base material 15 or providing a notched finger hooking part in which a part of the base material 15 is removed. Further, the concealment information displayed on the display card 1 can be variously set without being limited to the deposit balance. Further, the concealing sheet adhered to the display card 1 may be the concealing label 10 or a sheet-shaped member regardless of its name. Furthermore, it goes without saying that the present invention can be applied to a sheet member such as a postcard in addition to the card 20.

Effect As is clear from the above description, according to the present invention, by forming the surface side of the pressure-sensitive adhesive in a concavo-convex shape, by providing the adhesion enhancing layer on the concealed information display sheet,
Even if the adhesive strength of the adhesive provided on the concealment sheet is set to be weak enough to be peeled off, the concealment sheet and the concealment information display sheet are firmly adhered to each other in the adhesion enhancing layer to form the concealment information carrier, and then they are handled. While the concealing sheet can surely cover and conceal the concealing information without the possibility of peeling from the concealing information display sheet, by peeling the concealing sheet from the concealment information display sheet at least in a portion other than the adhesion enhancing layer,
The hidden information can be easily made visible.
