Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a postcard in which a concealment label is attached to the surface of a postcard in order to conceal and protect personal information on the surface of the postcard.

[0002]

2. Description of the Related Art Recently, automatic account transfers such as health charges and electricity / telephone charges have become popular, and along with this, transfer notifications that describe the transfer amount and the like are sent by postcards with low postage. Is being done. Then, in order to protect the personal information (privacy), a label called a secret label is attached to a portion where the personal information is described.

This label completely protects and conceals the surface of the postcard during mailing, and the recipient can see the contents written on the surface of the postcard only after peeling off the label. As shown in FIG.
1), a film 103 made of polyethylene or the like is laminated on the lower side of the aluminum foil 102, and a transparent film 104 made of polyester or the like extruded under the temperature adjusted to a temperature at which the film 103 is not completely adhered. ) Is laminated, the pressure sensitive adhesive (105) is applied under this, and it is covered with a release paper (106).

At the time of use, the release paper (106) is peeled off, and the postcard on which personal information (having privacy) is displayed is attached by a pressure sensitive adhesive (105) so as to cover at least this display portion. Put on. Since the aluminum foil (102) exists in this state, the surface of the postcard can be concealed because the aluminum foil does not pass through the light when the postcard is viewed through the light, not to mention the usual case. Will be mailed. When the recipient peels off the label, it peels between the film (103) and the transparent film (104), and the transparent film (104) remains on the postcard so that the film (104) is not sticky. Because it is transparent, the contents displayed on the postcard can be read.

The paper (101) and the aluminum foil (102)
And two perforations (10
7) is provided, and a peeling varnish having a width slightly wider than the width of the two perforations (107) is formed on the film (103).
And a transparent film (104).
This is for facilitating the peeling of the adjacent portion by peeling off the perforation (107) portion when peeling the label.

[0006]

In the above-mentioned conventional label, since the peeling is performed between the two kinds of films, the label is not peeled off from the postcard at the time of mailing, and when the recipient peels the label, the surface of the postcard is removed. In order to surely separate the films without damaging the film, it is necessary to have a high level of technology to control the temperature at which the synthetic resin forming the film (104) is extruded, and the device is also large-scale. There's a problem. In addition, since aluminum foil is used for concealment, the cost is high, and the incineration process cannot be performed for disposal, which is not preferable.

[0007]

SUMMARY OF THE INVENTION In view of the above problems, the present invention simplifies processing by forming a peeling surface by using a printing processing technique rather than using a peeling surface between two kinds of synthetic resin films. It is a postcard with a concealment label using the concealed label.

[0008] As a constitution, a base material mainly made of a paper having a concealing property, a transparent ink layer having poor adhesiveness, a pressure sensitive adhesive layer, and a release paper are laminated in this order, and the base material is formed. A postcard with a concealment label, which is a concealment label that can be peeled between the transparent ink layer and the transparent ink layer, and in which the release paper is peeled off and the pressure-sensitive adhesive layer is applied onto the display portion of the postcard.

[0009]

According to the postcard with the concealment label of the present invention, when the release paper of the concealment label is peeled off and attached to the display portion of the postcard with the pressure-sensitive adhesive, the content of the postcard display by the base material having the concealment property is provided. Is completely hidden. When the concealment label is to be peeled from the postcard, the transparent ink layer has poor adhesion, so it peels between the base material and the transparent ink layer, and this peeled surface is formed by the ink layer and is completely dried. Since it does not adhere to itself again, it cannot be restored to its original state, and the trace of unsealing becomes clear.

[0010]

The present invention will be described in detail below with reference to the drawings. FIG. 1 shows an example of a hiding label. In order to impart hiding properties to the base material (1), solid ink is printed on the back surface of the base material (1) made of paper or the like. To form a black ink layer (2), and a transparent ink (3) having poor adhesion to the black ink layer on the lower surface of the black ink layer (2).
Is printed on the entire surface to form a transparent ink layer (3), then the pressure sensitive adhesive (4) is applied to the lower surface of the transparent ink layer (3), and the transparent ink layer (3) is covered with a release paper (5).

The release paper (5) to which a pressure-sensitive adhesive has been applied and dried in advance may be attached so as to face the transparent ink layer (3) side of the substrate (1).

Next, FIG. 2 shows how to use the postcard with the concealment label. First, the release paper (5) of the concealment label is peeled off, and the pressure sensitive adhesive is applied so as to cover the display portion (6) of the postcard (7) and mailed. As long as the label is not peeled off, the display portion (6) is completely hidden, and even if the postcard is seen through the light, the black ink layer (2) does not pass through the light so that it cannot be seen through.

When the recipient peels off the label, a separation surface is formed between the black ink layer (2) and the transparent ink layer (3), and as shown in FIG. 3, the base material (1) and the black ink layer (2). It is possible to read the hidden display part (6) through the transparent ink layer (3) and the pressure-sensitive adhesive layer (4). At this time, the transparent ink layer (3) is completely dry and does not have adhesiveness (viscosity), which is convenient for storing postcards.

Further, even if it is illegally opened, it is impossible to attach it again between the black ink layer (2) and the transparent ink layer (3), and if the original state is restored. Since the trace remains, it is effective in preventing unauthorized opening.

FIG. 4 shows another embodiment of the concealment label, which comprises a substrate (1), a black ink layer (2), a transparent ink layer (3), a pressure sensitive adhesive layer (4) and a release paper (5). ) Are laminated in order, and the basic constitution up to this point is the same as that of the embodiment of FIG. 1, and in this embodiment, the black ink layer (2) is provided on the back surface of the base material (1). Perforations (8) having a desired width are formed in a laminated state, and then a release agent (9) having a wider width than the perforations (8) is spot-printed on the lower surface of the black ink layer (2). Is. The perforation (8) and the release agent (9) serve as a trigger for facilitating peeling on the peeling surface (p).

The black ink layer (2) used in the present invention for enhancing the hiding property is composed of a pigment of any color, a resin binder, a solvent, and other additives (eg tackifier, etc.). System, chlorinated rubber system, urethane system, nitrified cotton, vinyl chloride acetate system, chlorinated PP system, etc. can be used or a fatty amide or silicon system etc. can be added to these for easy adjustment, The thickness is preferably in the range of 0.5 to 5 μm.

The transparent ink layer (3) is also composed of a resin binder, a solvent, and other additives (such as tackifier, etc.), and it has a poor adhesiveness with the black ink layer (2). Generally called OP varnish, using nitrified cotton, polyamide system, chlorinated rubber system, urethane system, vinyl chloride system, chlorinated PP system, curable urethane system, phenol system, melamine alkyd system, epoxy system, etc. Alternatively, a fatty amide or a silicon-based material may be added to these to adjust the peeling easily, and the layer thickness is preferably in the range of 0.5 to 5 μm.

In order to reduce the adhesive force between the black ink layer (2) and the transparent ink layer (3) among the above-mentioned types of ink, either black ink or transparent ink is used as described above. On the other hand, it is also effective to add and use a fatty amide or a silicon-based component to both or both, and with a resin binder and a solvent contained in the black ink layer,
It is also preferable to select a combination in which the resin binder and the solvent contained in the transparent ink layer are mutually insoluble. Specifically, a chlorinated rubber type is selected as the black ink layer (2) and the transparent ink layer (3) is selected. When a nitrified cotton + polyamide system was selected and produced, excellent results were obtained.

[0019]

According to the present invention, which has the above-mentioned structure, the postcard has a concealing property which is excellent as a postcard in which the display unit is concealed and cannot be restored to its original state when it is illegally opened, so that confidentiality and safety are secured. it can. In addition, since the peeling surface of the concealment label is formed with an ink layer, the manufacturing process is simpler and the cost can be reduced compared to the conventional label having a structure in which two kinds of films are used as the peeling surface. It is a postcard with a concealment label that is extremely excellent in practical use without any problems.
