Description

  The present invention relates to a concealment label applied to an information entry member such as a postcard in which personal information is described.

  With the enactment of the Personal Information Protection Law from 2005, it is necessary to protect personal information described in reply postcards mailed by customers in industries such as correspondence education and credit sales.

  Conventionally, in order to protect personal information in relation to mailing, a form that returns personal information in a sealed envelope can be re-peeled to a place where personal information on a postcard is written. A method in which a sticker is attached and sent back (for example, see Patent Document 1, Patent Document 2, and Patent Document 3), or a seal in which two films are pseudo-bonded to a place where personal information of a postcard is described. A method of attaching and replying (for example, see Patent Document 4) has been used as appropriate.

  However, the method using a sealed letter has a problem that the mailing cost is high.

In addition, even if a method using a re-peelable seal or a method of attaching and replying with a seal in which two films are pseudo-bonded, even if a third party peels off the seal during mailing and steals personal information, The third party could re-apply the sticker without leaving any trace, and the contents described on the postcard could be tampered with, so personal information could not be completely protected. Furthermore, in the method of attaching and returning a sticker in which two films are pseudo-bonded, the glossiness of the seal is high, so the part where the seal is attached (the part covered with the seal) under white light Because the angle at which the information described in the above can be read is limited, it is very inconvenient.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a concealment label having low manufacturing cost and excellent confidentiality.

  The present invention mainly comprises an emulsion-type re-peeling adhesive comprising a first member, a second member made of color ink sequentially laminated on one surface of the first member, and a water-soluble powder dye. A third member made of a pressure-sensitive adhesive as a component, a fourth member made of release ink provided on a surface of the third member opposite to the surface in contact with the second member, and the first member of the fourth member There is provided a concealing label comprising: a fifth member affixed to a surface opposite to a surface facing the member and a surface of the third member opposite to the surface in contact with the second member.

  According to such a configuration, when the concealment label is affixed to the adherend, the water-soluble powder dye does not migrate to the adherend from the region where the fourth member of the third member is provided. On the surface to which the concealment concealment label is affixed, a white pattern is formed which consists of a region where the water-soluble powder dye is transferred and colored, and a region which is not colored.

  The concealing label of the present invention comprises a release ink on the surface opposite to the surface in contact with the second member of the third member made of a pressure-sensitive adhesive containing a water-soluble powder dye as a main component. Since the fourth member formed in a predetermined pattern is provided, when pasted on the adherend, from the region of the third member where the fourth member is provided, the adherend is soluble in water. Since the powder dye does not migrate, an area where the water-soluble powder dye migrates and is colored and an area which is not colored are formed on the surface of the adherend having the concealing label attached. As a result, a white pattern composed of the two regions is formed on the surface of the adherend on which the concealment label is attached. Therefore, according to the concealment label of the present invention, since a trace of fraud by a third party can be left, fraud by a third party can be suppressed and the confidentiality of personal information can be enhanced. Furthermore, since the concealment label of the present invention can be manufactured mainly by a coating process using various inks, it can be manufactured at a lower cost than a conventional concealment label formed by laminating sheet-like base materials. In addition, since the process can be simplified, the manufacturing cost can be reduced as a result.

  Hereinafter, the concealment label which implemented this invention is demonstrated in detail.

(First embodiment)
FIG. 1 is a schematic sectional view showing a first embodiment of a concealment label according to the present invention.
The concealment label 10 of this embodiment includes a first member 11, a second member 12 and a third member 13 that are sequentially stacked on one surface 11 a of the first member 11, and a second member 12 of the third member 13. The fourth member 14 provided on the opposite surface (hereinafter referred to as “one surface”) 13a and the surface opposite to the first member 11 of the fourth member 14 (hereinafter referred to as “the one surface”). 14a and a fifth member 15 affixed to one surface 13a of the third member 13.

  In the concealment label 10, the fourth member 14 is formed on one surface 13 a of the third member 13 in a predetermined pattern such as a character or a pattern. As the characters formed by the fourth member 14, for example, the label 10a formed by peeling the fifth member 15 from the concealment label 10 is attached to the adherend such as a postcard, and then the label 10a is peeled off from the adherend again. Inverted images such as “opened”, “VOID”, “OPEN” and the like that clearly indicate the left and right characters are listed.

  Moreover, in the concealment label 10, one surface 13a of the third member 13 and one surface 14a of the fourth member 14 form an adhesive surface to be attached to an adherend such as a postcard.

  Examples of the first member 11 include substrates such as paper, fine paper, synthetic paper, coated paper, sealing paper (such as those coated with polyvinyl alcohol), polypropylene film, PET film, and the like. In addition, as the release agent and the base material, known ones can be used as appropriate.

  Examples of the material forming the second member 12 include ultraviolet curable color inks. Among the color inks, indigo-colored and black-based ones are preferable.

  Examples of the material forming the third member 13 include a pressure-sensitive adhesive containing a water-soluble powder dye and mainly composed of an emulsion-type re-peeling pressure-sensitive adhesive. The amount of the water-soluble powder dye contained in the pressure-sensitive adhesive is preferably 0.01% by mass or more and 5% by mass or less, and more preferably 0.1% by mass or more and 1% by mass or less.

  If the amount of the water-soluble powder dye contained in the pressure-sensitive adhesive forming the third member 13 is within the above range, this water-soluble powder can be used when the label 10a is attached to an adherend such as a postcard. Not only does the dye easily migrate (elute) to the surface of the adherend (the area in the vicinity of the surface to which the label 10a is applied), but also the water-soluble powder dye migrates (elutes). The characters and patterns formed on the surface affixed with the label 10a become clear.

  The water-soluble powder dye is not particularly limited as long as it has a property of easily transferring (eluting) to the adherend when the adherend such as a postcard is made of plain paper, and any material can be used. . Note that plain paper generally has a moisture content of 3 to 7% by mass, and the water-soluble powder dye used in the present invention has such a property that it can be easily dissolved in moisture slightly contained in plain paper. It is.

  Examples of the re-peeling adhesive include acrylic adhesives and rubber adhesives containing microspheres.

  Examples of the material forming the fourth member 14 include a release ink made of an ultraviolet curable ink containing about 1% by mass or more and 10% by mass or less of reactive silicone or silicone oil.

  Examples of the fifth member 15 include release substrates made of substrates such as paper, synthetic paper, coated paper, polypropylene film, and PET film, to which a release agent such as silicone or non-silicone is applied. In addition, as the release agent and the base material, known ones can be used as appropriate.

Next, with reference to FIG. 2 and FIG. 3, the usage method of this concealment label 10 is demonstrated.
After peeling off the fifth member 15 from the concealment label 10, the label 10 a provided with the fourth member 14 formed on the reverse image 14 </ b> A in which the left and right of the pattern of characters and patterns are reversed is attached to an adherend 20 such as a postcard. If it sticks so that the area | region 21 in which the personal information etc. in one side 20a of the side was described may be covered (refer FIG. 2, FIG. 3 (a)), it will be water-soluble to the to-be-adhered body 20 from one side 13a of the 3rd member 13. Active powder dye migrates (elutes).

  At this time, since the water-soluble powder dye does not migrate (elution) from the region where the fourth member 14 is provided on the one surface 13a of the third member 13 to the adherend 20, On one surface 20a, a region 22 colored by migration of a water-soluble powder dye and a region 23 not colored are formed. As a result, a white normal image 14B is formed (transferred) on one surface 20a of the adherend 20 which is inverted from the reverse image 14A of the fourth member 14 (see FIG. 3B). ). That is, for example, as described above, if the reverse image 14A of the fourth member 14 is formed in a pattern in which the left and right characters such as “opened”, “VOID”, and “OPEN” are reversed, the adherend 20 A regular image 14B of characters such as “opened”, “VOID”, “OPEN”, and the like is formed (transferred) on one surface 20a.

  Further, as shown in FIG. 3B, the label 10a is peeled off from the adherend 20 by a third party, and the personal information described on one surface 20a of the adherend 20 is stolen, and then the label is displayed. Even if 10a is affixed again, the normal image 14B is formed in duplicate on one surface 20a of the adherend 20 unless the label 10a is reapplied accurately with an accuracy of 0.1 mm. From this, it can be seen that the label 10a has been removed. Therefore, if the concealment label 10 is used, since a trace of fraud by a third party can be left, fraud by a third party can be suppressed and the confidentiality of personal information can be increased.

  Further, the normal image 14B is formed (transferred) on the end of the area where the label 10a is attached on the one surface 20a of the adherend 20, that is, the peripheral edge of the one surface 13a of the third member 13 If the fourth member 14 is provided in the part, even if the label 10a affixed to the adherend 20 is slightly wound, the trace can be left.

Next, with reference to FIG. 1, the manufacturing method of the concealment label of this embodiment is demonstrated.
First, an ultraviolet curable color ink is applied to the entire surface of one surface 11 a of the first member 11, and this color ink is dried to form the second member 12.
Next, the surface of the second member 12 opposite to the surface in contact with the first member 11 contains a water-soluble powder dye by a comma coater, gravure coater, roll coater, etc. the pressure-sensitive adhesive mainly composed ^5g / ^{m 2 ~20g} / m 2 was applied, the adhesive by hot-air drying to form a third member 13.

  Next, a release ink made of an ultraviolet curable ink containing reactive silicone or silicone oil is applied to one surface 13a of the third member 13 in a predetermined pattern, and the ultraviolet curable ink is dried, The fourth member 14 having the pattern is formed.

  Finally, the fifth member 15 is attached to one surface 13a of the third member 13 and one surface 14a of the fourth member 14 to obtain the concealment label 10.

  Thus, since the concealment label 10 can be manufactured mainly by a coating process using various inks, it can be manufactured at a lower cost than a conventional concealment label formed by laminating sheet-like base materials. . Moreover, since the manufacturing method of the concealment label 10 mainly includes an application process, the process can be simplified, and as a result, the manufacturing cost can be reduced.

Next, the concealment postcard to which the above-described concealment label 10 is applied will be described with reference to FIG.
FIG. 4 is a schematic cross-sectional view showing an embodiment of a concealment postcard to which the concealment label of the present invention is applied. FIG. 4A is a diagram showing a state where the label is attached to the postcard, and FIG. 4B is a diagram showing the label removed from the postcard. FIG.
In FIG. 4, the same components as those of the concealment label 10 shown in FIG.

  The concealing postcard 30 of this embodiment is roughly composed of a postcard 31 and a label 10a attached so as to cover an area where personal information on one surface 31a of the postcard 31 is described.

  In this concealed postcard 30, as shown in FIG. 4A, a label 10 a is attached to one surface 31 a of the postcard 31 so as to cover an area where personal information or the like is written, From the area where the fourth member 14 is provided on the surface 13a, water-soluble powder dye does not migrate (elute) to the postcard 31, and from other areas the water-soluble powder to the postcard 31 The dye has migrated (eluted). Therefore, the surface layer of the postcard 31 (the region in the vicinity of the one surface 31a to which the label 10a is attached) is formed with a region A in which the water-soluble powder dye has been transferred and a region B in which it is not colored. Yes.

  Therefore, as shown in FIG. 4B, when the label 10 a is peeled off from the postcard 31, white letters or patterns formed by the area A and the area B formed on one surface 31 a of the postcard 31 appear.

  Even in the concealed postcard 30, as described above, after the label 10 a is peeled off from the postcard 31 by a third party and the personal information described on one surface 31 a of the postcard 31 is stolen, the label 10 a Even if affixed again, unless the label 10a is reapplied accurately with an accuracy of 0.1 mm, a white character or pattern is formed twice on one surface 31a of the postcard 31. From this, it can be seen that the label 10a has been removed. Therefore, if the concealment postcard 30 is used, a trace of fraud by a third party can be left, so that fraud by a third party can be suppressed and the confidentiality of personal information can be increased.

(Second embodiment)
FIG. 5 is a schematic cross-sectional view showing a second embodiment of the concealment label according to the present invention, wherein (a) is a diagram showing a state before the concealment label is used, and (b) and (c) are concealment labels. It is a figure which shows the usage method.
The concealment label 40 of this embodiment includes a first member 41 composed of one piece 41A and another piece 41B with a polygonal line 50 as a boundary, a second member 42 and a third member 43 stacked in order on one surface 41a of the one piece 41A, The fourth member 44 provided on the surface (hereinafter referred to as “one surface”) 43a opposite to the surface of the third member 43 in contact with the second member 42, and the first member 41 of the fourth member 44 It is schematically configured from a surface (hereinafter referred to as “one surface”) 44 a opposite to the opposing surface and a fifth member 45 attached to one surface 43 a of the third member 43.

  In the concealment label 40, the fourth member 44 is formed on the one surface 43 a of the third member 43 in a predetermined pattern such as letters and patterns. As a character which the 4th member 44 forms, for example, after sticking the label 40a which peels the 5th member 45 from the concealment label 40 to a to-be-adhered body (here other piece 41B), it is a label from an to-be-adhered body again. Examples include reverse images in which the left and right characters of “opened”, “VOID”, “OPEN”, etc., which clearly indicate that 40a has been removed, are reversed.

As the 1st member 41, the thing similar to said 1st member 11 is mentioned.
As the material forming the second member 42, the same material as that forming the second member 12 is used.
As the material forming the third member 43, the same material as that forming the third member 13 is used.

As the material forming the fourth member 44, the same material as that forming the fourth member 14 is used.
As the adhesive forming the fifth member 45, the same adhesive as that forming the fifth member 15 is used.

  In the concealment label 40, as shown in FIG. 5 (b), the first member 41 is bent at the folding line 50, and the label 40a formed by peeling the fifth member 45 from the concealment label 40 is replaced with one of the other pieces 41B. When affixed to the surface 41a, the water-soluble powder dye does not migrate (elute) from the region where the fourth member 44 is provided on one surface 43a of the third member 43 to the other piece 41B. From this area, the water-soluble powder dye migrates (elutes) to the other piece 41B. Therefore, the surface layer of the other piece 41B (the region in the vicinity of the one surface 41a to which the label 40a is attached) and the region in which the water-soluble powder dye is transferred and colored (region C shown in FIG. 5C) and An uncolored region (region D shown in FIG. 5C) is formed (see FIG. 5B).

  Therefore, as shown in FIG. 5C, when the label 40a is peeled off from the other piece 41B, a white character or pattern formed by the region C and the region D formed on one surface 41a of the other piece 41B is obtained. appear.

  Even in the concealment label 40, as described above, after the label 40a is attached to the other piece 41B, the label 40a is peeled off from the other piece 41B by a third party, and is described on one surface 41a of the other piece 41B. Even if the label 40a is affixed again after the personal information is stolen, white characters are not printed on the one surface 41a of the other piece 41B unless the label 40a is affixed accurately with an accuracy of 0.1 mm. Alternatively, since the pattern is formed twice, it can be seen that the label 40a has been peeled off. Therefore, if the concealment label 40 is used, since a trace of fraud by a third party can be left, fraud by a third party can be suppressed and the confidentiality of personal information can be increased.

  The concealment label 40 can also be used as a concealment postcard.

  Further, the concealment label 40 of this embodiment can be manufactured in the same manner as in the first embodiment described above.

  The concealment label of the present invention can also be applied to election ballots, lotteries, and seals for seal protection.
