Description

  The present invention relates to a pressure-bonded postcard sheet, and more particularly, to a pressure-bonded postcard sheet that mixes a stress luminescent material in a releasable and non-re-stickable adhesive that adheres by pressurization and emits light in a predetermined area when peeled off from an adhesive portion .

Postcards using paper with adhesive that can be re-removable and non-re-pasteable are used as mailings for financial institutions and public institutions, but in recent years, private information has also been printed by private companies due to its simplicity and cost Used as direct mail.
These postcards have a high opening rate when used as a notification means for the above financial institutions, but are often discarded without being opened when a company or the like is used for direct mail or the like.
Therefore, in order to increase the opening rate, companies that send direct mails include useful information on the recipients of postcards and devices that make them want to open them.
Conventionally, there was a mechanism that pops out when opening as a mechanism to increase the opening rate of direct mail, but when a mechanism that pops out on the crimping surface is included, there are problems such as being unable to be handled as a postcard by the current postal code there were.
2. Description of the Related Art In recent years, a technique for using a stress-stimulated luminescent material (for example, see Patent Document 1) that emits light by simply touching it with a hand or a finger for artificial skin, a light emitting system, a display system or the like has been disclosed.

It is a figure for demonstrating an example of the crimping postcard sheet | seat of this Embodiment. It is a figure for demonstrating other examples of the pressure-bonded postcard sheet | seat of this Embodiment. It is the sectional view on the AA line of FIG. It is a figure for demonstrating the procedure from which the crimping postcard sheet | seat of this Embodiment is folded and becomes a postcard. It is a figure for demonstrating the state which opened the adhesion part in order to see the communication information of a postcard.

With reference to FIG. 1, an example of the pressure-bonded postcard sheet | seat of this Embodiment is demonstrated.
The pressure-bonded postcard sheet 1 according to the present embodiment has two or three folded postcard-sized paper pieces connected to each other at the scheduled folding portions 11 and 12, folded together, and bonded on opposite surfaces to be postcards. A type of postcard sheet.
The example of the pressure-bonded postcard sheet 1 shown in FIG. 1 is an example of a three-fold pressure-bonded postcard sheet in which three pieces of postcard-sized paper pieces are connected by the scheduled folding portions 11 and 12, but on the left side of the folded portion 11 in FIG. There is a case of a “two-fold crimped postcard sheet” without a piece of paper.
In the case of the “two-fold crimped postcard sheet”, as described above, the destination information is displayed on the back side of the piece of paper that is composed of two pieces of paper and sandwiched between the planned folding part 11 and the planned folding part 12 in FIG. It becomes the form (not shown) made.
Therefore, when printing the outgoing information 22 on the inner side to be bonded, it must be printed by a printing device (printer) capable of printing on the front and back.

In the following description of the embodiment, an example of a three-fold type crimped postcard sheet 1 will be described.
In the case of the “three-fold type crimped postcard sheet”, unlike the above-described “two-folded crimped postcard sheet”, the destination information 21 and the outgoing information 22 are printed on the same surface in a state before being bonded. The destination information 21 and the transmission / reception information 22 can be printed simultaneously by a single-sided printer.

In FIG. 1, among the three paper pieces of the pressure-bonded postcard sheet 1, a peelable and non-re-stickable adhesive containing a stress-stimulated luminescent material on the entire surface of at least one of two adjacent paper pieces connected by the planned folding portion 12 ( (Hereinafter also referred to as a pressure-sensitive adhesive) 31 is formed, and a non-light emitting region 14 is formed on the outermost surface of any of the surfaces to be bonded with an ink that prevents adhesion (hereinafter also referred to as a peelable ink).
Although not shown in the drawings, pressure is also applied to at least one of the back surfaces on which the destination information 21 of the adjacent paper pieces connected by the scheduled folding portion 11 is printed in order to form a “single-layer postcard” in a stacked state. An adhesive is formed.
When bonded with a pressure-sensitive adhesive, there may be a case where the adhesive surfaces are bonded together, or an adhesive surface and a pressure-sensitive postcard sheet base material surface, and any form may be selected.

The pressure sensitive adhesive 31 formed on two adjacent paper pieces connected at the planned folding portion 12 and the destination information 21 of the adjacent paper pieces connected at the planned folding portion 11 (not shown) are printed on the back side. The formed pressure sensitive adhesive need not necessarily have the same properties.
When the amount of outgoing information is sufficient in FIG. 1, the pressure-sensitive adhesive formed on the back surface on which the destination information 21 of the paper pieces connected by the scheduled folding portion 11 is printed does not need to be peeled off.
In addition, information common to all of the postcards is printed on the surface on which the pressure-sensitive adhesive 31 of FIG. 1 is formed, or on the back surface of the paper piece on which the destination information 21 is printed and the adjacent paper piece. In some cases, outgoing information 22 including personal information that differs depending on the recipient is printed.

The non-light emitting area 14 may be printed with a free color or may be printed with a peelable ink having the same color as the pressure-sensitive adhesive 31 (usually the same color as the postcard sheet base material).
If the non-light emitting area 14 is printed in a free color, the contents can be visually recognized even after opening, but if it is printed in the same color as the pressure-sensitive adhesive 31, the surrounding light emitting area only when opening Is visually recognized as a non-light-emitting region.
In addition, the pressure-sensitive adhesive layer can be formed after a pattern or character is printed on the postcard sheet base material, and a pressure-sensitive adhesive (removable and non-re-adhesive adhesive layer = pseudo adhesive layer) 31 is formed. The finished surface can be given a variety of designs by combining the light-emitting part of the pressure-sensitive adhesive layer and the non-light-emitting part of the release ink.

When the pressure-bonded postcard sheet 1 is folded in three at the planned folding parts 11 and 12, and is made into a postcard, the peeling-scheduled part 13 is provided so as to be easily peeled off at the surface bonded with the pressure-sensitive adhesive 31. There is.

With reference to FIG. 2, another example of the pressure-bonded postcard sheet according to the present embodiment will be described.
The example of the pressure-bonded postcard sheet 1 shown in FIG. 2 is an example in which a pattern is printed on the non-light emitting area 140 with a peelable ink.
In the example shown in FIG. 2, the non-light emitting area 14 is printed in a free color, and the design can be finely printed separately on the issuing part and the non-light emitting part.
In this case, a rich design can be imparted to the design, and impact can be given to the person who opens it.

With reference to FIG. 3, the AA line cross section of FIG. 1 is demonstrated.
The crimping postcard sheet 1 according to the present embodiment is a three-fold type crimping postcard in which three postcard-sized paper pieces are joined at the scheduled folding parts 11 and 12 and are folded and bonded to each other on the opposite surface. Sheet.
A pressure-sensitive adhesive 31 containing a stress-stimulated luminescent material is formed on the entire surface of the postcard sheet base material 10 of two adjacent paper pieces connected by the planned folding portion 12 among the three paper pieces of the pressure-bonded postcard sheet 1, and the planned folding portion. A non-light-emitting region 14 made of a releasable ink is formed on the exposed surface of the pressure sensitive adhesive on the right side of the paper 12.
Moreover, the pressure sensitive adhesive 32 is formed also on the back side (the reverse side where the pressure sensitive adhesive 31 was formed) of the adjacent paper piece connected by the scheduled folding part 11 of the postcard sheet base material 10.
Recipient's destination information is printed on the surface of the left side of the adjacent paper pieces connected by the planned folding portion 12 on which the pressure sensitive adhesive 31 is not formed.

As described above, the pressure-sensitive adhesive 31 and the pressure-sensitive adhesive 32 do not necessarily have the same characteristics. The pressure-sensitive adhesive formed on the back surface on which the destination information 21 of the paper pieces connected by the scheduled folding part 11 is printed may or may not need to be peeled off.
When the amount of outgoing information is sufficient in FIG. 1, the pressure-sensitive adhesive formed on the back surface on which the destination information 21 of the paper pieces connected by the scheduled folding portion 11 is printed does not need to be peeled off.
In this case, the pressure-sensitive adhesive 32 does not need to contain a stress luminescent material.

With reference to FIG. 4 and FIG. 1, the procedure for folding the pressure-bonded postcard sheet of the present embodiment to become a postcard will be described.
First, it is folded so that the destination information is outside on the planned folding portion 11 shown in FIG. 1, and the pressure sensitive adhesive 31 is folded inside on the planned folding portion 12.
Next, pressure is applied in the direction of the arrow to bond the pressure sensitive adhesives together. Since the pressure-sensitive adhesives are bonded in a pseudo-bonded state, the pressure-sensitive adhesive can be peeled off from the pseudo-bonded surface if a peeling force is applied for opening.

With reference to FIG. 5 and FIG. 1, a state where the adhesive part is opened in order to see the postcard transmission information will be described.
When the postcard is received, the integrated three-layer postcard is peeled off from the “part to be peeled off” 13. At this time, the peeling stress acts on the surface of the “pressure-sensitive adhesive” 31, and the portions other than the non-light emitting region 14 become “fluorescent emission state”.
As a result, the recipient pays attention to the “non-light emitting area” 14 together with an instant surprise, and confirms the content displayed there.

With reference to a part of FIG. 3, the material used for the crimping postcard sheet 1 of this Embodiment is demonstrated.
As the postcard sheet base material 10, fine paper, coated paper, art paper, synthetic paper, milk white PET, milk white PLA (polylactic acid), or the like can be used.
In Japan, a standard for postcards (postcards) has been decided, and it is necessary to make it according to this plan (size: long side 14.0 to 15.4 cm, short side 9) 0.0 to 10.7 cm, weight: 2 to 6 g).
In either case of folding in two or three, the above-mentioned standard must be satisfied in a finished state as a “postcard”. For this purpose, the weight of the postcard sheet substrate (the weight or the continuous weight) is selected in consideration of the standard.

The stress luminescent material is, for example, a material in which an element serving as a luminescent center is added to an inorganic crystal skeleton whose structure is highly controlled, and can be obtained in the form of fine powder particles.
Materials that emit light at various wavelengths from ultraviolet to visible to infrared have been obtained by selecting the kind of inorganic material or emission center.
Stress luminescent materials can be divided into stress luminescent fluorescent materials and stress luminescent phosphorescent materials according to the decay time of light emission by given energy.
Examples of the fluorescent material include CaMgSiO ₇ : Ce, SrNb ₂ O ₆ : Eu (see, for example, Japanese Patent Application Laid-Open Nos. 2007-55144 and 2008-55639).

The pressure-sensitive adhesive 31 includes a styrene-butadiene rubber and microsilica, and a pressure-sensitive adhesive in which these are dispersed in water, for example, an adhesive described in JP-A-8-176526. In a composition in which an inorganic filler is added at a ratio of 5 to 100 parts by weight with respect to 100 parts by weight of the main agent, an acid-modified polyvinyl alcohol having no compatibility with the adhesive main agent at a ratio of 3 to 21% by weight. An added pressure-sensitive adhesive (described as a pressure-sensitive adhesive in the publication) is used.

The ratio of the stress-stimulated luminescent material in the pressure-sensitive adhesive as the luminescent region varies depending on the coating method, but it is preferable to prepare in the range of 5 to 20% by mass from the viewpoint of necessary adhesive strength, luminescent intensity, and economy. .

As the releasable ink used in the non-light emitting region, a commercially available UV curable ink for offset printing added with silicone oil or added with silicone acrylate is used.
Commercially available screen printing, gravure printing, flexographic printing, offset printing, and relief printing ink are used as ink for postcard design printing and wording printing.

The pressure-bonded postcard sheet of the present invention can be used for mailed items used in financial institutions, public institutions, credit card companies, distribution industries, and the like.
