BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a secret reciprocal postcard in which a pressure-sensitive adhesive layer is formed on a concealing surface of a base material, and a secret information entry field having confidentiality by concealing secret information at the time of outgoing communication. In addition, it is a secret reciprocal postcard with a large number of information entry fields that can print variable data on the front and back sides such as the general information entry fields for outgoing and reply.

[0002]

2. Description of the Related Art In the past, a round-trip postcard was generally used for notification of attendance at meetings, reply to questionnaires, etc. In addition, a letter was used for a confidential notice from a financial institution such as a securities company or a bank, or a government agency, and a reply postcard was enclosed for those requiring a reply.

[0003]

However, since the personal information described in the postcards can be read from the outside, it cannot be used for the contents related to privacy. Therefore, a letter is used for a confidential notice from a financial institution such as a securities company or a bank, or a government agency, and a reply postcard is enclosed for those requiring a reply. If the envelope and the reply postcard are included in the envelope and sent by mail, the concealment of the notification content can be maintained, but at the time of creating the envelope or correspondence form, the envelope address and confidential information Ordinary information is printed separately, these forms are matched with the address and private information for each individual, sealed, mailed, and other complicated operations are added, resulting in poor efficiency, easy mismatch, and high cost. There was such a drawback.

An object of the present invention is to provide a variable data section on all six sides of a three-fold mail form, and arrange it so that more information including an outgoing mail address, a reply address, and confidential information can be written, Both sides can be printed simultaneously, and the confidential information entry field at the time of outgoing communication can be concealed and concealed. Also, at the time of opening, the protrusion provided on the side end of the concealed paper sheet or the back surface of the second paper sheet An easy-to-release adhesive layer of a pressure-sensitive adhesive layer from a non-adhesive portion is provided, which improves efficiency when creating a form, and provides an inexpensive and highly reliable reciprocating postcard.

[0005]

In order to solve the above-mentioned problems, a mail form according to the present invention has a postcard-sized first sheet, a second sheet, and a third sheet on the long side. In almost all of the planned contact surface of the base material to be a reciprocating postcard that is continuously provided via a folding line, a pressure-sensitive adhesive layer is formed by pressure, and secret information is printed on the surface of the pressure-sensitive adhesive layer, A mail form characterized by being able to be peeled off from the pressure-sensitive adhesive layer after the base material is bent and the pressure-sensitive adhesive layers on the opposite surfaces are brought into close contact with each other to conceal the printed surface. A reply address entry field on the surface of the paper sheet, a general information entry field on the second paper surface, a contact address entry field on the third paper surface,
A reply information entry field is provided on the back surface of the first paper sheet, a confidential communication information entry field is provided on the back surfaces of the second and third paper sheets, and the third paper sheet is wider or narrower than the second paper sheet. Then, when the pressure-sensitive adhesive layers on the surfaces to be adhered are brought into close contact with each other by folding in three folds, the third paper sheet side edge protrudes from the first paper sheet and the second paper sheet folding section, or A mail form characterized in that a non-adhesive portion that does not adhere to the third paper sheet is provided on the back surface of the second paper sheet.

There is.

Next, the layer structure will be specifically described. The base material 11 is usually white fine paper,
If the surface is roughened by corona treatment or matte treatment, synthetic resin films such as PET, PE, PP and vinyl chloride can be used. The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 12 is adjusted so as to facilitate the adhesion and re-peeling of the contact surface, and the adhesive main agent, the adhesive strength adjusting agent, the additives, etc. described below are Mixed in proportion. Adhesive main agent 100 parts by weight Adhesion control agent In the case of needle-shaped substances 10-100 (preferably 10-50) parts by weight In the case of fine-grained substances 0-50 (preferably 5-30) parts by weight When the above substances are mixed 10 to 100 parts by weight Additive wax 0.01 to 20 parts by weight Ultraviolet absorber Small amount defoaming agent Small amount defoaming aid Small amount emulsifying component Water 100 to 500 (preferably 200 to 300) parts by weight Emulsifier 0.5 to 2 Parts by weight resin 1 to 50 parts by weight

[Adhesive Main Agent] The adhesive main agent is a natural rubber (N
R), esterified natural rubber, styrene butadiene rubber (SBR), chloroprene rubber, polyvinyl acetate, polymethylmethacrylate (PMMA) and the like, or a mixture thereof. In mixing these adhesive main agents, by appropriately adjusting the mixing ratio, the adhesiveness to the base material can be made higher than the adhesiveness while maintaining the self-adhesiveness between the pressure-sensitive adhesives. Preferably, a natural rubber having a high property of exhibiting self-adhesiveness between pressure-sensitive adhesives under pressure is added with polymethylmethacrylate or styrene-butadiene rubber for the purpose of enhancing the adhesiveness with a base material, that is, the anchor effect. Is mentioned. Polymethylmethacrylate is preferably used as a mixture with another adhesive main agent rather than used alone. As such an adhesive main agent, fine particles having a particle size of about 0.1 μm to 3 μm are usually used.

[Adhesive Strength Adjusting Agent] The adhesive strength adjusting agent is mixed in order to adjust the adhesive strength of the adhesive main agent, and a needle-like substance or a fine particulate substance or a mixture thereof is used. Needle-like substance As the needle-like substance, any of an inorganic substance and an organic substance may be used, as long as the shape thereof is substantially needle-like, flat, spiral,
Although it is arbitrarily selected from those having various forms such as scales, a needle-shaped substance is particularly preferable. The needle-shaped substance has an average length of 10 μm to 20 μm and an average diameter of 0.2.
It is preferably about μm to 0.5 μm. Needle-like substances
It is preferable that the pressure-sensitive adhesive be an emulsion and have an apparent specific gravity of 0.05 to 0.6 in order to reduce the sedimentation property when it is used as a coating agent. Further, in consideration of printing processing and NIP suitability, a needle-shaped substance Has an elastic modulus of 10000 kg / mm ²
It is preferably about 40,000 kg / mm ² . Examples of such needle-like substances include glass fiber, carbon fiber, P
AN-based fibers, metal crystals, metal compound crystals, and the like,
The adhesive main agent may be one that has no affinity (compatibility). A preferable acicular substance is a crystal of potassium 6-titanate (K ₂ O.6TiO ₂ ), which has no compatibility with water but has an affinity and has an apparent specific gravity of 0.2.
(True specific gravity = 3.3), elastic modulus 28,000 kg / mm ²
And is suitable as a pressure-sensitive adhesive component.

Fine particulate materials The fine particulate materials include micro silica, synthetic zeolite, activated alumina gel, calcium carbonate, zinc oxide, titanium oxide, talc, clay, kaolin, activated clay, acrylic beads, starch, cellulose, silas balloons, etc. The particles having a particle size of 10 mμm to 30 μm, preferably 0.5 μm to 10 μm are suitable.
Further, by adding together with the needle-shaped substance, it is possible to reduce the addition amount of the fine-grained substance and prevent the fine-grained substance from falling off.

[Additives] As additives, waxes such as polyethylene wax and carnauba wax are used to improve handling properties, slipperiness such as NIP transport performance and blocking resistance, and ammonia for preventing deterioration. UV absorbers such as ethanolamine may be added. Further, as an antifoaming agent, a nonionic surfactant,
An anionic surfactant (mineral oil type) may be added, or silica or the like may be added as a defoaming aid.

[Emulsifying Component] The above-mentioned tackifying main agent, tackiness adjusting agent, and additives are dispersed in a medium such as water and applied to a substrate in an emulsion state. When emulsifying, an emulsifier is added if necessary. As the emulsifier, oleic acid soap, potassium castor oil soap, casein, glue, gelatin and the like can be used. Further, in order to prevent secondary aggregation of the adhesive main agent when emulsified, a resin having no affinity with the adhesive main agent can be added. As this resin, a water-dispersible polymer polyester,
Thermoplastic elastomer, low molecular weight polyethylene such as low density polyethylene, ionomer, vinyl acetate-olefin copolymer and the like can be preferably used.

The coating amount of such pressure sensitive adhesives, after drying ^{0.1g / m 2 ~10g / m 2} , preferably 1.0g
/ M ^{2 to} 3.0 g / m ² is preferable. Within this range, when printing or printing from the pressure-sensitive adhesive, the ink can penetrate through the pressure-sensitive adhesive and reach the substrate, and transfer of the printing layer when peeled off can be prevented. . Furthermore, blocking, piling (powder drop), etc. can be prevented, and sufficient adhesion and printability can be obtained.

Next, a method of using the mail form of the present invention will be described. First, the mail forms 10 and 20 of the first and second embodiments will be described.
NIP (non-impact printer) on the front and back of each sheet
Print at once using a double-sided printer such as. In addition, fixed information such as explanatory notes, figures, ruled lines, and general questions may be printed before printing. Further, the information to be printed is the address, name, etc. of the outgoing address information U and the reply address information V (however, the reply address information need not be printed when the replyee fills in), and as the confidential information X. Is personal information such as a maturity notification of a financial institution or a reminder letter.
In addition, in the communication confidential information entry fields (third paper sheet back surface 3 ′ and second paper sheet back surface 2 ′ shown in FIG. 1 (b)), individual question items such as a questionnaire to the recipient should be printed. You can also Further, in this case, an answer column is printed on the first paper back surface 1 '. After that, fold the mail form 10 or 20 from the planned folding line p to make a Z fold,
The surfaces coated with the adhesive layer 12 are brought into close contact with each other and pressed to form a confidential reciprocal postcard. (Shown in FIGS. 4 and 5)

If mailed in this state, the postage will be treated as a postcard. When the recipient tries to open the sheet, the adhesive layer 12 on which the paper sheet on which the confidential information of the outgoing message is printed adheres is peeled off and opened. At this time, the mail form 10 described with reference to FIG. 4 uses the protrusion α on the side edge of the third paper sheet as a trigger for peeling, so that the pressure-sensitive adhesive that adheres closely between the second paper sheet and the third paper sheet. The layers of the layer 12 can be easily peeled off and opened. Similarly, in the case of the mail form 20 shown in FIG. 5, the non-adhesive portion β of the second paper sheet that does not adhere to the third paper sheet
With the effect of, the adhesive layer can be easily peeled off and the confidential information can be opened without damaging it. Furthermore, as mentioned above,
Communication secret information entry field (the third sheet back surface 3 ′ shown in FIG. 1,
In the case where individual question items such as questionnaires to recipients are printed on the second paper back surface 2 ') and an answer field is printed on the reply information entry field (first paper back surface 1') Is
The recipient is a question field such as a questionnaire from the sender (the third sheet back surface 3 ′ and the second sheet back surface 2 ′ shown in FIG. 1)
Then, since the reply column from the replyee (the first sheet back surface 1 ′ shown in FIG. 1) is on the same surface, the reply can be entered while comparing and referring. Also, as a similar usage,
Even if a special product information is printed or printed in the confidential communication information entry field and the reply information information entry field such as a purchase application is in the reply information entry field, the product should be compared while comparing the contents on the same surface. Since it is possible to select and fill in, it is possible to further enhance the commercial characteristics of the return postcard.
And when replying to the confidential information or replying to the questionnaire, the respondent who is the recipient of the postcard is
If the reply address information is not printed in the reply address entry field, the reply address information can be filled in by itself and the first sheet can be separated from the reciprocating postcard and mailed as a reply postcard. Next, the mail form 30 of the third embodiment will be described. It is almost the same as the method of using the mail forms of the first and second embodiments described above, but the folding method in the case of a reciprocating postcard is Z. It is different from the point that it is not a fold but a roll fold and the positional relationship of each information entry column.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the present invention. The print area and print information are not particularly limited. It is desirable that the size and weight when folded are ordinary reciprocal postcards defined by the Postal Law, but they are not particularly limited in consideration of the usage form. The mail form may be continuous paper or single-cut paper when printing information, and the printer is not limited to NIP, and a dot impact printer or the like may be used. Information or the like that does not require confidentiality can be appropriately printed on this mail form.

[0020]

As described in detail above, according to the present invention, since the items to be described at the time of outgoing communication are concealed, there is no concern that the described information will be leaked to a third party, and the address information, confidential information, Since general information can be printed on both sides at the same time, the matching of the address and confidential information can be surely achieved, which is efficient, and the mailing cost is lower than that of the sealed letter. In addition, since the outgoing communication secret information entry field and the reply information entry field appear on the same surface, the replyer can enter the reply information while referring to the information in the outgoing communication secret information entry field. Further, by providing the protruding portion or the non-contact portion, the contact portion can be easily peeled off. Furthermore, by providing a non-contact part,
High reliability evaluation can be obtained without the trouble of transporting the automatic zip code reader at the post office. Furthermore, the present mail form creation has an advantage that the processing machine and process of the tri-fold mail form, which is widely used at present, can be used as it is.
