Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a label for temporarily hiding characters, patterns, etc. attached to the surface of an adherend or the back surface of the label itself.

[Conventional technology]

Recently, because insurance fees, electric telephone charges, etc. are automatically transferred,
The money transfer notice is sent by postcard. This postcard is problematic from a privacy standpoint because it can be seen by others. Therefore, various labels have been conventionally provided so as to conceal a part of a postcard.

For example, Japanese Patent Publication No. 55-15035 discloses a label having a configuration in which paper, a transparent film, a pressure-sensitive adhesive layer, and a release paper are formed in order from the top layer, and can be peeled between the paper and the transparent film (hereinafter referred to as a peel portion). It has been disclosed. Moreover, in Japanese Utility Model Application No. 63-35455, paper, a Sumi ink layer, a transparent ink layer,
A concealing label having a pressure-sensitive adhesive layer and a release paper and having a peel portion between a smear ink layer and a transparent ink layer is provided.

[Problems to be solved by the device]

However, when the label disclosed in Japanese Examined Patent Publication No. 55-15305 is attached to a postcard and used, there are the following drawbacks. That is, when the label is peeled off, the transparent film remains on the postcard side, so that the paper is warped due to the difference in elasticity between the film and the paper (postcard), and because of its thickness, the flexibility of the paper disappears. It is difficult to adjust the adhesive strength of the peeling part between the paper and the transparent film. Since only one piece of paper is concealed,
It may not be completely hidden.

In Japanese Utility Model Application No. 63-35455, in order to overcome the above-mentioned drawbacks, a transparent film is eliminated and a smear ink and a transparent ink are used. That is, by eliminating the transparent film, the warpage of the paper was eliminated, and the flexibility of the paper was maintained. Further, the use of Sumi Ink makes the concealing property perfect, and the peeling between the Sumi Ink layer and the transparent ink layer facilitates the adjustment of the adhesive force. However, the surface of the ink portion is rough, and if you apply transparent ink to this surface and try to peel it between them,
There is a fear that peeling unevenness may occur.

The present invention has been made in view of such circumstances, and provides a label with good hiding property and peeling property, such as perfecting hiding property and not causing peeling unevenness when peeling the label. To aim.

Another object of the present invention is to provide a concealment label that can have a hidden character, a symbol, or the like on the back surface of the label itself, thereby expanding the range of use.

[Means for solving the problem]

In order to solve the above problems, this invention has a transparent film and a transparent ink layer which are laminated so as to face each other, and a peeling portion is provided between them to improve the releasability, and an opaque colored paint is applied to the back surface of the base paper. Applying two layers of white paint to improve the hiding property, and by adding hiding characters and symbols on the back of this white paint layer, it is possible to add hiding characters and symbols to the label itself. It is the one.

That is, the invention is based on a base paper, an opaque colored paint layer applied to the back surface of the base paper, a white paint layer applied to the back surface of the colored paint layer, and an adhesive on the back surface of the white paint layer. A laminated body comprising a transparent film adhered; a transparent ink layer applied to the transparent film side of the laminated body; releasable to the transparent ink layer via a pressure-sensitive adhesive The present invention provides a concealable label comprising an adhesive release paper, wherein the laminate and the transparent ink layer can be peeled off from each other.

A pattern layer to be hidden may be provided on the back surface of the white paint layer. In this case, it is preferable from the viewpoint of hiding property that the pattern layer has a color similar to that of the opaque colored coating layer, for example, a black color.

[Action]

The opaque colored paint layer and the white paint layer applied to the back surface of the base paper can completely hide the pattern of characters, symbols, etc. on the adherend, and the laminate can be peeled from the transparent ink layer once. In that case, this laminate cannot be adhered again onto the ink layer. This makes it possible to prevent falsification.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 schematically shows a cross section of a concealing label according to an embodiment of the present invention.
And an opaque colored paint layer 2 applied to the back surface of the base paper 1.
And a white paint layer 3 applied to the back surface of the colored paint layer 2.
The transparent film 5 adhered to the back surface of the white paint layer 3 via the adhesive 4, the transparent ink layer 6 applied to the back surface of the transparent film 5, and the back surface of the transparent ink layer 6 It is composed of a release paper 8 which is detachably attached via a pressure-sensitive adhesive 7.

A laminated body which is integrally peeled from the transparent ink layer 6 (from the portion indicated by "a" in the figure) at the time of peeling by the base paper 1, the opaque colored paint layer 2, the white paint layer 3, the adhesive 4 and the transparent film 5. 10 are configured.

The material of the base paper 1 is not particularly limited and may be appropriately selected depending on the purpose. The opaque colored paint layer 2 is preferably a black paint having high opacity, but may be any other color system such as brown, silver, or dark blue as long as it can provide opacity. In this case, it is preferable that the characters and symbols to be concealed provided on the adherend (or provided on the white paint layer 3 of the label as described later) have a similar color to the concealing property.

The white paint layer 3 is made of a paint containing a white pigment and the like, and in particular, clay, kaolin, calcium carbonate,
It is preferable to add a filler such as titanium white, den powder, or SBR to allow the printing ink to permeate to some extent.

As the transparent film 5, a thermoplastic having good transparency, for example, polyvinyl chloride, polyethylene, polypropylene or the like can be appropriately selected. As the transparent ink layer 6, an ordinary transparent varnish, for example, an acrylic resin, a urethane resin, a vinyl chloride / vinyl acetate copolymer, or a mixture thereof can be used.

The method for producing the concealing label is not particularly limited, but it can be produced, for example, by the following steps.

First, an opaque colored paint layer is formed by printing an opaque colored paint layer on one entire main surface of a base paper 1 (for example, a coated paper having a basis weight of 80 g / m ² ), and then white clay is placed on the opaque colored paint layer 2. On the whole surface to form a white paint layer 3, and then the white paint layer 3 or the transparent film 5 (for example, a thickness of 30 μm)
Coating the two-component urethane resin adhesive on top,
These are adhered and laminated to each other, and then a transparent ink (release varnish) is coated on the transparent film 5 side to form a transparent ink layer 6 (for example, a thickness of 5 to 8 μm). On the other hand, the release paper 8 is coated with, for example, 7 g / m ^{2 of a} pressure sensitive adhesive 7 (for example, rubber-based or acrylic resin-based) and dried, and then the pressure-sensitive adhesive 7-coated surface and the transparent ink layer 6 surface are coated. Overlap and join. This completes the concealment label.

When actually using this label on a postcard, for example,
The release paper 8 is peeled off and attached to the portion to be concealed. In this state, the characters written on the postcard are hidden and cannot be seen from outside. Next, when the recipient of the postcard tries to remove this label, the adhesive strength between the transparent ink layer 6 and the transparent film 5 is smaller than the adhesive strength between the postcard and the pressure-sensitive adhesive layer 7. , The label peels off naturally at the peel part "a". Then, the recipient can read the pattern 11 such as characters in the concealed portion (see FIG. 2). In addition, 12 in FIG. 2 shows a postcard.

FIG. 3 is a sectional view showing the structure of a concealment label according to another embodiment of the present invention. The basic structure is exactly the same as that shown in FIG. It is composed of a colored paint layer 2, a white paint layer 3, an adhesive 4, a transparent film 5, a transparent ink layer 6, a pressure sensitive adhesive 7 and a release paper 8. Here, the only difference from the embodiment shown in FIG. 1 is that, as shown in FIG. 3, a pattern 13 such as arbitrary characters and symbols to be concealed is attached to the back surface of the white paint layer 3.

After the white paint layer 3 is formed, the pattern 13 is printed on the back surface of the white paint layer 3.

The method of manufacturing and using the concealment label of FIG. 3 is basically the same as that of the concealment label of FIG. 1, but in this case, the pattern such as characters and symbols to be concealed on the peeled laminate 10 side. Since the reference numeral 13 is attached, the pattern 13 can be confirmed from the transparent film 5 side of the laminated body 10 after the laminated body 10 is peeled off.

In any of the above-mentioned examples, when the transparent film 5 and the transparent ink layer 6 are once peeled off, since they originally have no adhesive property, they cannot be bonded again. Therefore, if the third party strips it off, it will be immediately known.

[Effect of device]

As described in detail above, according to the concealment label of the present invention,
Since the two layers of the opaque colored paint layer and the white paint layer are provided on the back surface of the base paper in layers, it is possible to improve the concealability of concealment characters and the like on the adherend (for example, a postcard), and By using the white paint layer, it becomes possible to apply a character or symbol to be concealed on the concealment label side as well.

Therefore, the range of use of the concealment label can be broadened, and, for example, in addition to confidential stickers, secret labels,
It has become possible to use it as a seal for hiding lottery and concealing.

In addition, since the peel portion is formed between the transparent film and the transparent ink, smooth delamination can be obtained without causing uneven peeling. In addition, the adjustment of the delamination strength is facilitated. Further, since the film layer does not remain on the adherend (postcard) after peeling as in the related art, it is possible to prevent warpage of a postcard or the like and loss of flexibility. The label of the present invention has excellent concealing properties, and since the peel part cannot be re-bonded once it has been peeled off, it is possible to prevent tampering.
