DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive seal capable of appropriately binding and collecting not only a seal body but also a release sheet which is usually discarded.

[0002]

2. Description of the Related Art A seal body having a pressure-sensitive adhesive layer formed on a back surface and a printed portion on which characters, designs and the like are printed on a front surface,
2. Description of the Related Art A pressure-sensitive adhesive seal comprising a release sheet which is removably polymerized on the pressure-sensitive adhesive layer of the seal body has been widely known. In such an adhesive seal, various characters such as slogans and various designs, for example, designs of popular anime characters are printed on a printing portion of the seal main body, and the seal main body is provided at a desired place or tool by a user. Used by pasting. On the other hand, the release sheet protects the pressure-sensitive adhesive layer of the seal main body, and ends its role when the seal main body is peeled off.

[0003]

As described above, the release sheet in the conventional pressure-sensitive adhesive seal protects the pressure-sensitive adhesive layer of the seal body and stops its function when the seal body is peeled off. It was just something. Also, even if each seal has a small area of about several centimeters, a seal on which various designs and patterns are printed is formed on one sheet, and it can be half-cut and separated independently. Such a configuration is well known in magazine appendixes and the like. However, it is difficult to use up all kinds of seals at once, and the work itself is not fun. Therefore, even if only some of the various types of seals are used and the rest are to be preserved, the sheets themselves are easily lost, and if they are handled sloppyly, they often adhere to undesired places and become wasteful. Was. Therefore, by making the configuration of the release sheet different from that of the conventional release paper, not only does the release sheet have a commercial value, but also the commercial value of the entire pressure-sensitive adhesive seal is significantly improved. The purpose is to improve the properties.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above, and has a seal having a pressure-sensitive adhesive layer formed on a back surface and a first printed portion on which characters and designs are printed on the front surface. It consists of a main body and a release sheet formed with a second printed part on the surface of which characters, designs and the like are printed, and a release layer formed on the upper surface thereof. The adhesive layer of the seal body and the release layer of the release sheet are attached. An adhesive seal comprising: a second printed portion of a release sheet exposed on the surface of the adhesive seal through a seal body; and a binding means formed at an end of the adhesive seal. is there.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The seal body of the pressure-sensitive adhesive seal of the present invention has a pressure-sensitive adhesive layer on the back surface and a first surface on the front surface as described above.
This is a configuration in which a printed portion is formed, and is basically the same as the seal body of the conventional adhesive seal. Therefore,
With respect to the configuration of the adhesive layer, the configuration of the base material forming the seal body, the configuration of the first printing unit, and the method of manufacturing them, any known configuration and manufacturing method may be adopted. For example, characters or the like may be described by a writing instrument such as a pen as appropriate by appropriately selecting a printing ink or a surface treatment of a base material for forming the first printing section. Further, since the adhesive seal of the present invention is configured such that the second printed portion of the release sheet located on the back side of the seal body is exposed to the surface through the seal body, at least the base material forming the seal body is peeled. The second printed portion of the sheet is made of a film having such transparency as to be visible. Further, the first printing portion formed on the surface of the seal body is usually provided only in a part so that the second printing portion is exposed from a surface other than the first printing portion. When formed with ink or the like having a low concealing property, the second printed portion can be exposed through the first printed portion even if the first printed portion is provided on the entire surface.

The release sheet in the pressure-sensitive adhesive seal of the present invention has a structure in which the second printed portion is formed on the surface and a release layer is formed on the upper surface as described above, and its base material (base material before printing) For example, blank paper, art paper, coated paper,
Fine paper, bleached kraft paper, bleached kraft paper, paperboard, hologram processed paper, aluminum transfer processed paper, cellophane, etc., or vinyl chloride (PVC), polyester (PET), nylon, polystyrene (PS), polyethylene (P
E), various plastic films such as polypropylene (PP), plate-like plastic molded products, hologram processed films, aluminum transfer processed films, nonwoven fabric, synthetic leather, synthetic paper, foamed plastic materials, and the like.
Further, for example, a paper material having a rough surface may be appropriately subjected to a sealing treatment.

In the subsequent printing (second printing section), the printing ink, the printing method, the design, and the like to be used are not limited. For example, various types of printing can be performed on the base material using a known in-line printing apparatus. Multicolor characters, colors and the like may be sequentially printed, or may be printed using an offset type or screen type printing device. When printing is performed using a multicolor printing apparatus, an OP varnish, a clear varnish, a general-purpose sealing material, or the like may be printed for the first time, or the printing ink may be printed thickly. A sealing effect may be obtained. In addition, any known printing ink may be used. For example, precision printing that looks like a photograph may be performed. Further, such printing may be performed not only on the front side but also on the back side of the base material.

Alternatively, a printing film or the like already provided on the market as a product may be used as the peeling substrate on which the second printed portion is formed.

The release sheet substrate on which the second printed portion is formed may be subjected to a step of forming a release layer as it is,
If necessary, an intermediate intervening layer may be provided for the purpose of imparting folding resistance (flexibility), imparting rigidity, or filling. The coating material for forming the intermediate intermediate layer preferably has excellent adhesion to the base material and the printed portion, and more preferably has excellent adhesion to the release layer described later. In addition, as a coating material for the intermediate intermediate layer, a transparent resin paint (ink) is usually used.
Etc., but may be colored as long as the printed surface is not concealed. However, if a release layer described later is provided without providing an intermediate intervening layer, it can be collected and recycled as recycled paper, contributing to resource saving. On the other hand, the conventional release paper cannot be recycled as recycled paper because the release layer is formed on the laminate after being subjected to a polylaminating process (laminating process of polyethylene resin of about 20 μm).

The release layer in the present invention is not particularly limited as long as it is a film having transparency and releasability at the time of completion of curing, but has a break resistance (flexibility). It is desirable. The transparency may be such that the second printed portion can be visually observed through the release layer, and may be colored as long as the second printed portion is not concealed. The release layer preferably has excellent adhesion to the second printed portion. In the case where the second printed portion is formed only on a part of the base material, not on the entire surface, it is preferable that the second printed portion has excellent adhesion to the base material. When the intermediate layer is formed, it is preferable that the intermediate layer has excellent adhesion to the intermediate layer. For example, a silicone-based paint is generally used as a coating material for forming the release layer, but a silicone resin and a natural or synthetic resin may be used in combination. As the natural or synthetic resin, acrylic, vinyl chloride-vinyl acetate (vinyl chloride vinyl chloride)
System, nitrifying cotton system, styrene system, polyester system, urethane system, vinylidene chloride system, vinyl acetate system, acryl-vinyl chloride system, styrene-acryl system, aminoalkyd system, polyolefin system, etc. Can be used for Further, any configuration such as a heat-drying resin composition and an ultraviolet-curing resin composition may be used. The UV-curable resin includes one or more monomers or prepolymers having a radical polymerizable unsaturated double bond, a sensitizer as an essential component, and various additives such as other resins, colorants, and waxes. And a monomer having a radical polymerizable unsaturated double bond of the ultraviolet-curable resin, such as ethylene glycol, polyethylene glycol, trimethylolpropane, and pentaerythritol. Esterified acrylic acid, phthalic acid, maleic acid, isocyanuric acid, etc. esterified with allyl alcohol, or glycidyl (meth) acrylate esterified one is used.

Various additives and chemicals may be added to the intermediate layer and the release layer according to the purpose. For example, the release layer may have an antibacterial effect. In the conventional adhesive seal, since the release paper was discarded after the seal body was peeled off in a plain color, such an antibacterial effect was unnecessary, but the release sheet in the present invention can be collected and enjoyed itself. Thus, the second printing unit is formed. Therefore, the release sheet in the present invention, after peeling the seal body, it is assumed that the hands and fingers frequently contact,
It is desirable to have excellent antibacterial properties. Specifically, in order to impart an antibacterial effect to the release layer, an inorganic antibacterial agent or a less toxic organic antibacterial agent is added in a range of 0.1 to 10%. If the amount of this antibacterial agent is less than 0.1%, a sufficient antibacterial effect cannot be exhibited. Further, when the addition amount is more than 10%, gloss, gloss, and transparency as commercial values are impaired even when the antibacterial agent is finely dispersed. More preferably, it is 0.6 to 2.5%. It should be noted that many organic antibacterial agents have toxicity, and have a drawback that they are eluted during use and the antibacterial effect is not maintained for a long time. Therefore, inorganic antibacterial agents and organic antibacterial agents having low toxicity are used. This inorganic antibacterial agent uses the antibacterial power of silver and zinc, and has antibacterial calcium phosphate (a substance in which antibacterial metal ions such as silver and zinc are exchanged and adsorbed on calcium phosphate and immobilized). Zeolite (a porous synthetic zeolite using alumina and silica as raw materials, in which sodium ions are replaced by silver and zinc ions of antibacterial metal), antibacterial silica gel (silica gel alone, and after carrying a silver thiosulfato complex, A part or all of the surface of which is coated with a coating material such as tetraethoxysilane or tetramethoxysilane) or the like is used, but the present invention is not particularly limited thereto. In this case, the release layer is
It is desirable that the thickness be 0.5 to 10 μm (dry thickness). When the thickness is less than 0.5 μm, a sufficient antibacterial effect is not exhibited due to the relationship with the content of the inorganic antibacterial agent.
When the thickness is more than 10 μm, the transparency is impaired also in relation to the content of the inorganic antibacterial agent.

Further, a binding means having an appropriate structure is formed at an end of the adhesive seal of the present invention. The binding means may have any known configuration, such as a configuration in which a plurality of holes are arranged in a column. Although not particularly limited, the adhesive seal of the present invention usually has a structure in which a single sheet-shaped seal body is divided into various types, that is, a single seal body is subjected to printing of various patterns and patterns. In many cases, a configuration is employed in which a large number of seal pieces can be independently peeled off by half blanking.

As described above, since the binding means is formed on the adhesive seal of the present invention, it can be bound appropriately, without being lost or deteriorating the commercial value. Can be used.
Therefore, for example, in a state where several sheets of the adhesive seal of the present invention are bound to form a seal album, or for example, in recent years,
Multifunctional notebooks (system notebooks) equipped with storage pockets for banknotes and cards, etc., are commercially available. In such a notebook that can be added, several sheets of the adhesive sticker of the present invention are bound, and appropriately. The seal piece can be peeled off and used.

Further, printing on a release sheet (second printing section)
, The design can be enjoyed before and after the seal is removed. Further, the visual change can be enjoyed. In particular, when the second printed portion of the release sheet is configured to be exposed on the surface through the seal body, the combined image of the first printed portion and the second printed portion can be enjoyed. For example, when various characters are printed in the form of dots as a release sheet print (second print section), and a frame-shaped pattern is printed so as to surround each of the characters as a seal body print (first print section). Such an adhesive seal has an appearance as if the character is written in a frame-shaped pattern, so that even when not in use before peeling off the seal body, it is possible to give the user a taste of hobby, and to motivate collection. Can be evoked. Also, in this case, the seal body is usually composed of a transparent base material, and a frame-shaped pattern is printed, so for example, if this is pasted on a face photograph or a snap photograph of a size that fits in the frame, The appearance is as if it were printed on a photo mount in which a frame-shaped pattern is drawn in advance, and it is possible to satisfy the user's taste. Furthermore, as a printing (first printing portion) of the seal body, not only a frame-shaped pattern but also a pattern such as a beard, eyebrows, glasses, and the like are applied, and the sticker piece is attached to an image of a snap photograph and enjoyed. It is expected that various types of play will be devised.

On the other hand, since the release sheet from which the adhesive seal has been peeled is also subjected to printing (second printing section), a large number of seal pieces are peeled and used (there are few remaining seal pieces). However, the binding page is always lively, and for some users, the release sheet itself is to be collected and stored, and the product value can be maintained as it is. In particular, the second printed part of the release sheet is printed with excellent design such as a trading card, so that many buyers can collect
You may make it a storage object.

Further, in recent years, a photo printing apparatus called a so-called three-minute photograph is digitized, and a printing base material supplied is labeled, and a device for simultaneously printing a flower pattern or the like on an image surface (trade name "Print Club") ], Commonly known as Pulikura, has been developed, and the seal photographed with this device (also known as Pulikura seal) has become popular among younger generations, especially female students. May be made to stick a pre-cleaner seal as described above. With Purikura, you can obtain a sticker with many identical images formed on one sheet, so you can stick it on your belongings or stationery instead of writing your name or use it for sealing envelopes The most common use is to exchange a photo sticker between friends, carry the sticker on a commercially available sticker album so that the function as a sticker is not lost, and show off each other. However, the sticker albums that are already on the market are nothing more than those made of plain release paper in the form of notebooks, and especially when starting to use, there are few stickers of stickers, so they are not very visually interesting. Therefore, when a plurality of release sheets in the adhesive seal of the present invention are collected and bound and used as a sticker album, the release sheet itself is printed (second printing section), so that the bound pages are visually lively. It will be. Further, since a release sheet obtained by binding several adhesive stickers to the system organizer and appropriately peeling off the seals can be used as a backing sheet for sticking the pre-cleaner sticker, it is not necessary to carry the sticker album. There is also an advantage. As described above, the release sheet has a high commercial value as an album (backing sheet) for a pre-closure seal, and is an article that female students and the like desire to collect. As described above, the purpose of collecting the release sheet is not necessarily limited to the value as a printed matter, and the release sheet may be collected and stored as an album (backing sheet) for a pre-class seal.

Further, although the present invention is not limited to the product form of the adhesive seal, the adhesive seal is provided with a binding allowance, and a folding page (folding appendix) of a magazine, a book, a notebook, or the like is provided.
It may be. This binding margin is usually provided at the end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings.

An adhesive sheet was produced as shown below. Various patterns such as various characters (6) on A2 coated paper (9) with a basis weight of 175 g by UV offset printing machine
Was printed. Is composed of 5% extender pigment, 20% photosensitive polymer (polyester resin), 15% photosensitive monomer (acrylic monomer), 45% photopolymerization initiator, and 15% auxiliary (silicone and wax). A UV-curable OP varnish (7) was applied to produce a release sheet (8) having releasability. Adhesive 2 by the print laminator shown in FIG.
(Trade name “BPS-5569” manufactured by Toyo Ink Co., Ltd.) is diluted in an equal amount with ethyl acetate, and a 38 μm polyester film (5) is prepared by a reverse roll method (A is a coating roll).
About 20 g / m ² · dry, and the thinner is evaporated (C is exhausted) by a dryer B (Erofin), and then bonded to the release sheet 8 prepared in (D is a hot roll,
E was an impression cylinder), and immediately thereafter, it was dropped into a single sheet by a continuous cutter machine F. A variety of patterns (such as a pattern paired with the pattern of the release sheet 8 prepared in) were printed again on the single-sheet adhesive tacky film manufactured in, using an offset printing machine. Finally, cutting, punching and perforation were performed to obtain an adhesive seal 1 (product) as shown in FIG.

The pressure-sensitive adhesive sheet 1 of the present invention shown in FIG. 2 has a pressure-sensitive adhesive layer 2 formed on the back surface, a seal body 4 (transparent substrate 5) having a first printed portion 3 formed on the front surface, and a pressure-sensitive adhesive layer 2 formed on the front surface. 2. A release sheet 8 (base material 9) on which a printed portion 6 is formed and a release layer 7 is formed on the upper surface thereof, and the adhesive layer 2 of the seal body 4 and the release layer 7 of the release sheet 8 are bonded together. It is configured. The adhesive seal 1 has a binding margin 10 formed at the left end and a cutting perforation 11 for separating from the binding margin 10, and a binding means 12 having six holes at the left and right ends. However, a perforation 13 for cutting / bending is formed on the slightly right side of the center. And
The second printed portion 6 of the release sheet 8 is exposed on the surface of the adhesive seal 1 through the seal body 4. The adhesive seal 1 not only enhances the decorative effect when the seal main body 4 is attached to a desired portion, but also has a desired effect even when the seal main body 4 and the release sheet 8 are not used when they are superposed. It can enhance the decorative effect and motivate consumers to collect.

Further, since the binding margin 10 is formed on the adhesive seal 1 as described above, it can be used as a folding appendix of magazines 14 as shown in FIG.

Further, since the binding means 12 is formed in the adhesive seal 1, the adhesive seal 1 can be appropriately bound in a notebook as shown in FIG. 15 can be used as a backing sheet on which to paste.

When the adhesive seal 1 shown in FIG. 1 is bound as shown in FIG. 4, the perforation 13 is cut as shown in FIG. May be used as the binding sheet. Alternatively, as shown in FIG. 5B, the perforations 13 may be bent and bound. In the former case, the page located on the right side of the facing portion becomes the peeling (printing) surface, and the page located on the left side becomes the non-processed surface. In the latter case, all pages become the peeling (printing) surface.

In FIG. 2B, the cross-sectional structure is schematically shown, and the printing layer 72 is not necessarily provided on the entire surface, but may be provided on a part.

With respect to the release sheet 8 obtained as described above, a sample was prepared and a sheet was prepared under the conditions shown in FIG. As a comparison, a release paper having a configuration in which a silicone release layer was formed on a conventional poly-laminate processing was similarly tested. The test equipment and test method were instructed at the Saitama Paper Industry Laboratory.

As shown in FIG. 7A, the release sheet 8 according to the embodiment of the present invention has a structure in which the silicone itself constituting the release layer is mixed in a resin and cured as described above. As a result, the whole was disintegrated (fine) by the pulper and finally did not remain until the sheet was formed, so that sufficient results were obtained as recycled paper. On the other hand, as shown in FIG. 7 (b), in the conventional release paper, the polyethylene resin is laminated about 20 μm under the silicone constituting the release layer, so that the pulper does not become too fine and the sheet finally becomes thin. Until the time of preparation, a piece of polyethylene (a film shape, which is indicated by hatching in the figure) was mixed, and a sufficient result was not obtained as recycled paper.

Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and can be implemented in any manner unless the configuration described in the claims is changed. it can. For example, in the illustrated embodiment, an example in which the release layer 7 is formed immediately above the second print portion 6 of the release sheet 8 has been described. An intermediate intermediate layer may be provided for the purpose of imparting properties and the like.

[0028]

As described above, the adhesive seal of the present invention not only enhances the decorative effect when the seal main body is attached to a desired portion, but also can be used in a release sheet after the seal main body is peeled off. This also enhances the desired decorative effect and motivates the consumer to collect. In addition, since the binding means is formed on the adhesive seal of the present invention, it can be appropriately bound, without loss or loss of commercial value, and when necessary, the seal body can be peeled off and used as desired. Can be. Furthermore, since the second printed portion is also formed on the release sheet after the adhesive seal has been peeled off, the bound pages are always busy even when many seal pieces are peeled and used (there are few remaining seal pieces). In addition, for some users, the release sheet itself is collected and stored, and the product value can be maintained as it is. In addition, it is assumed that the album is to be collected and stored as an album for a pre-class seal (backing sheet), thereby maintaining the product value.

Particularly, since the second printed portion of the release sheet is configured to be exposed on the surface through the seal body, the first printed portion is formed.
It can be configured so that the combined image of the printing unit and the second printing unit can be enjoyed.

When a binding margin is provided on the adhesive seal,
It can be a folding page (folding appendix) for magazines, books, notes, etc.
