(Book seal)
<First Embodiment>
A first embodiment of the book seal sticker of the present invention will be described.
FIG. 1 shows a book seal sticker according to this embodiment. The book sealing seal 1 includes a seal body 10 in which a pseudo adhesive layer 12 and an adhesive layer 13 are sequentially formed on a surface base material 11, and a release sheet 20 laminated on the adhesive layer 13 of the seal body 10. It has.
Further, in this book seal 1, a predetermined interval is provided between the release sheet 20 and a part of the surface base material 11 on the side of the pseudo adhesive layer 12 in the seal body 10, the pseudo adhesive layer 12, and the pressure-sensitive adhesive layer 13. A pair of cuts 30 and 30 are formed by two having. Here, it is preferable that the predetermined interval is substantially equal to the thickness of the book so that the seal of the book by the sticking of the book seal 1 can be reliably released.
In this book seal 1, the reason why the cuts 30, 30 are formed also in part of the surface base material 11 on the side of the pseudo-adhesion layer 12 is to make sure that the cuts are formed in the pseudo-adhesion layer 12.

Moreover, in this book seal 1, an easy-adhesion coat layer 14 is formed on the surface of the surface substrate 11 opposite to the pseudo-adhesion layer 12 and subjected to an easy-adhesion treatment. If the easy-adhesion coat layer 14 is formed, printing can be easily performed, and the design property of the book seal sticker 1 can be improved, or a catch phrase or information of the book can be written on the book seal sticker 1. it can.
The easy adhesion coat layer 14 is a part of the seal body 10.

Hereinafter, each configuration of the book seal sticker will be described in detail.
[Surface substrate]
Examples of the surface base material 11 in the seal body 10 include a film, a nonwoven fabric, and paper. Examples of the material for the film include polypropylene, polyethylene, polyester, polystyrene, polyvinyl chloride, nylon, cellophane, and polyvinyl alcohol. Moreover, as a material of a nonwoven fabric, pulp, rayon, Manila hemp, acrylonitrile, nylon, polyester, etc. are mentioned. Examples of paper include high-quality paper, resin-coated paper, water-soluble paper, and hydrolytic paper.

  The thickness of the surface substrate 11 is preferably 10 to 150 μm. If the thickness of the surface base material 11 is less than 10 μm, the strength of the seal for sealing the book becomes low, and it may break when attached to the book, and the book may not be securely sealed. On the other hand, when the thickness exceeds 150 μm, the flexibility of the seal for book sealing is lowered and it is difficult to stick to the book.

[Pseudo adhesive layer]
The pseudo-adhesion layer 12 is a resin layer that adheres to the surface substrate 11 in a peelable manner. Further, the pseudo-adhesion layer 12 is not particularly limited except that it is a layer using resins that are not compatible with each other when the surface base material 11 is heated and laminated, but a thermoplastic resin, a thermosetting resin, an elastomer, A layer using a high molecular weight polysaccharide such as cellulose is preferred. Specifically, for example, polyolefin-based thermoplastic resins such as polyethylene and polypropylene, fluorine-containing resins such as polytetrafluoroethylene and polyvinylidene fluoride, elastomers such as polyurethane, natural rubber and synthetic rubber, and carboxymethylcellulose Examples thereof include celluloses and polysaccharides such as starch. Among these, it is more preferable to use carboxymethyl cellulose which is a water-soluble resin.

  The pseudo adhesive layer 12 preferably has an adhesive strength of 0.05 to 1 N / 25 mm with respect to the surface base material 11. If the adhesive strength is less than 0.05 N / 25 mm, the seal may be peeled off from the book only by applying a slight external force. On the other hand, if it exceeds 1 N / 25 mm, the peel strength at the time of peeling at the interface between the surface base material 11 and the pseudo adhesive layer 12 becomes too strong, and the book cannot be easily unsealed, which is not preferable.

  The thickness of the pseudo adhesive layer 12 is preferably 1 to 50 μm, and more preferably 5 to 30 μm. If the thickness of the pseudo adhesive layer 12 is less than 1 μm, it is difficult to form the pseudo adhesive layer 12, and if it exceeds 50 μm, the pseudo adhesive layer 12 becomes excessively thick, which is uneconomical.

  Further, the pseudo adhesive layer 12 may be a single layer, but may be formed of a plurality of different resin layers. When formed from a plurality of layers, when the seal is released, the pseudo-adhesion layer 12 is peeled off between layers of different resins and separated into the surface base material 11 side and the pressure-sensitive adhesive layer 13 side, respectively. It may be a mechanism.

[Adhesive layer]
Examples of the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 13 include natural rubber, synthetic rubber, acrylic, silicone, urethane, and vinyl ether as polymer types. Examples of the form of the pressure-sensitive adhesive include solvent-based, emulsion-based pressure-sensitive adhesives, water-based pressure-sensitive adhesives, hot-melt pressure-sensitive adhesives, UV-curable pressure-sensitive adhesives, and EB-curable pressure-sensitive adhesives. It is done. Among these, a water-soluble pressure-sensitive adhesive is preferable because it can be recycled with a book seal sticker attached to a book. Examples of the water-soluble pressure-sensitive adhesive include Clariant Polymer Co., Ltd. Movinyl S-71, Soken Chemicals Co., Ltd. SK Dyne SK-1170, Big Technos Co., Ltd. AR-2090, which are a kind of acrylic pressure-sensitive adhesive. It is done.
Furthermore, in order to make it possible to visually recognize the printing of the book under the pressure-sensitive adhesive layer 13 in a state where the pressure-sensitive adhesive layer 13 is attached to the book, it is preferable to use a transparent pressure-sensitive adhesive.

  Moreover, the adhesive layer 13 may contain a tackifier in addition to the adhesive. Examples of the tackifier include C5 petroleum resin, alicyclic petroleum resin, alicyclic / aromatic petroleum resin, terpene resin, rosin resin, rosin ester resin, terpene-phenol resin, alkylphenol resin. Etc.

  The thickness of the pressure-sensitive adhesive layer 13 is preferably 10 to 40 μm, and more preferably 15 to 25 μm. If the thickness of the pressure-sensitive adhesive layer 13 is less than 10 μm, the adhesive strength to the book may be insufficient, and if it exceeds 40 μm, the pressure-sensitive adhesive layer 13 becomes excessively thick and uneconomical, as well as label processing. Sometimes the pressure-sensitive adhesive layer protrudes from the base material, which may cause troubles when performing a trimming process of margins and automatic sticking with an auto labeler.

[Easily adhesive coat layer]
The easy-adhesion coat layer 14 is made of, for example, SF Primer UGR, No. 1 manufactured by Dainippon Ink & Chemicals, Inc., which is a cellulose / urethane anchor coat agent. 930 etc. are mentioned.
The thickness of the easy-adhesion coat layer 14 is preferably 0.1 to 2 μm. When the thickness of the easy-adhesion coat layer 14 is less than 0.1 μm, the ink adhesion tends to be lowered. Moreover, when it exceeds 2 μm, it becomes too thick and uneconomical, and when the seal for book sealing is rolled up, the front surface and the back surface adhere to each other, causing a blocking phenomenon and making it difficult to feed the film. There is a risk that troubles such as adhesion of the easy-adhesion coat layer to the back surface and dropping off from the surface may occur.
The easy-adhesion coat layer 14 can be omitted when printing is not required.

[Peeling sheet]
Examples of the release sheet 20 include glassine paper, kraft paper, clay coated paper, paper laminated with a film such as polyethylene, paper coated with a resin such as polyvinyl alcohol or an acrylate copolymer, and synthetic materials such as polyester and polypropylene. Examples include a resin film or the like coated with a fluororesin or a silicone resin as a release agent. When automatic sticking is performed by a machine such as an auto-traveller, it is preferable to use glassine paper as a base substrate as a release sheet.

The shape of the book sealing seal 1 is not particularly limited as long as the book can be sealed, and may be a tape shape, a sheet (flat size) shape, or any other shape. There may be. In the case of a tape shape, it may be short enough to pass the edge portions on the front and back covers, or may be long enough to go around the book.
Further, the book sealing seal 1 may be wound in a roll shape as shown in FIG.
Further, the seal 1 for book sealing is provided with a label 10a as shown in FIG. 3 by inserting the second cuts 40, 40 into the seal body 10 and removing the seal body 10 outside the second cuts 40, 40. , 10a...

[Production method]
In order to manufacture the book seal 1, for example, first, an adhesive is applied to the release treatment surface side of the release sheet 20 to form the adhesive layer 13. As a method for applying the adhesive, for example, a known method using a gravure roll coater, roll coater, bar coater, comma coater, air knife coater, die coater or the like can be applied. The pressure-sensitive adhesive can also be applied by silk screen printing. When silk screen printing is applied, an arbitrary pattern or character can be formed on the adhesive layer.
Next, a thermoplastic resin melted by an extrusion laminating method is laminated on one surface of the surface base material 11, cooled to form the pseudo adhesive layer 12, and then the pressure-sensitive adhesive layer on the release sheet 20 on the side of the pseudo adhesive layer 12 13 are bonded and integrated to obtain a laminate. Then, using a slitter or the like provided with a cutting blade and a fixing means for fixing the position of the cutting blade, the cutting blade is put into the laminated body from the release sheet 20 side, and the release sheet 20 and the surface base material 11 of the seal body 10 are Cuts 30 and 30 having a predetermined interval are formed in a part of the pseudo adhesive layer 12 side and the pseudo adhesive layer 12 and the pressure-sensitive adhesive layer 13. In this way, the seal 1 for book sealing is obtained.

  In this example of the manufacturing method, the cuts 30 and 30 are formed while the release sheet 20, the pressure-sensitive adhesive layer 13, and the pseudo adhesive layer 12 are laminated. Cuts 30 and 30 may be formed in the adhesive layer 12 and the release sheet may be bonded again. However, if the cuts 30 and 30 are formed while the release sheet 20, the pressure-sensitive adhesive layer 13, and the pseudo-adhesive layer 12 are laminated, the cuts 30 and 30 can be easily formed in the pressure-sensitive adhesive layer 13 and the pseudo-adhesive layer 12.

In the book sealing seal 1 of the first embodiment described above, the release sheet 20 is peeled off, the adhesive layer 13 is exposed, and the adhesive layer 13 is adhered to the cover and back cover of the book. The book can be sealed. At that time, as shown in FIG. 4, the cuts 30, 30 formed in the pseudo adhesive layer 12 and the pressure-sensitive adhesive layer 13 in the seal body 10 are the edge 51 a of the edge 51 a of the front cover 51 of the book body 50 and the back cover 52. The seal body 10 is attached to the book body 50 along the line 52a.
When unsealing, the surface base material 11 of the seal body 10 is peeled off. At this time, in the region where the pressure-sensitive adhesive layer 13 of the seal main body 10 is adhered to the front cover 51 and the back cover 52 of the book main body 50 (hereinafter referred to as an adhesive region 10b), as shown in FIG. 11 peels from the pseudo-adhesive layer 12, and the surface base material 11, the pseudo-adhesive layer 12b and the adhesive layer 13b of the sticking part 10b are separated. Further, in the region where the pressure-sensitive adhesive layer 13 of the seal body 10 faces the small edge 53 a of the book body 50, the pseudo adhesive layer 12 a and the pressure-sensitive adhesive layer 13 a between the cuts are peeled from the book body 50 together with the surface base material 11. This is because the fore edge 53a has irregularities and is not attached to the adhesive layer 13a.
Thus, by peeling off the surface base material 11 and disassembling the seal body 10, the seal body 10 can be removed from the small edge without tearing the seal body 10, and the seal of the book can be easily released. .

  In addition, if such a seal body 10 of the seal 1 for book sealing is stuck on a winning prize or a serial number for application described on the front cover or back cover of the book body, it can be blindfolded simultaneously with the sealing of the book. Also demonstrates. The winning prize and the serial number for application can be seen when the surface base material 11 is peeled and the seal 1 of the book seal is released.

<Second Embodiment>
A second embodiment of the book seal sticker according to the present invention will be described.
FIG. 6 shows a seal for book sealing according to this embodiment. In the present embodiment, the same configurations as those in the first embodiment are denoted by the same reference numerals as those in FIG.
The book sealing seal 2 has a seal body 10 and a release sheet 20 laminated on an adhesive layer 13 of the seal body 10. Here, the seal body 10 has a pseudo adhesive layer 12 formed on the surface substrate 11, and a pair of pressure-sensitive adhesive layers 13 and 13 formed on the pseudo adhesive layer 12 at a predetermined interval. Is. Note that a space is formed between the pressure-sensitive adhesive layers 13 and 13, and when the book sealing seal 2 is attached to a book, the space is disposed in the forehead. By disposing the void portion in the fore edge, the adhesive layer 13 hardly remains in the fore edge when the seal is released.

In this book seal 2, cuts 30, 30 are formed at the boundary between a region 12 c in contact with the pressure-sensitive adhesive layer 13 and a region 12 d in contact with the pressure-sensitive adhesive layer 13 in the pseudo adhesive layer 12 of the seal body 10. .
In the book sealing seal 2, the width of the pressure-sensitive adhesive layer 13 is narrower than that of the release sheet 20 and the pseudo adhesive layer 12. If the width of the pressure-sensitive adhesive layer 13 is narrower than that of the release sheet 20 and the pseudo adhesive layer 12, the release sheet 20 and the like can be easily picked, and the release operation becomes easier.

As in the first embodiment, the book sealing seal 1 of the second embodiment is formed on the pseudo adhesive layer 12 and the adhesive layer 13 in the seal body 10 as shown in FIG. The book can be sealed by sticking the seal body 10 to the book body 50 so that the cuts 30 and 30 extend along the front edge 51a and 52a of the front cover 51 and the back cover 52 of the book body 50.
When unsealing, the surface base material 11 of the seal body 10 is peeled off. At this time, in the sticking region 10b, as shown in FIG. 8, the surface base material 11 is peeled from the pseudo adhesive layer 12, and the surface base material 11, the pseudo adhesive layer 12b and the adhesive layer 13b of the sticking part are formed. To separate. Moreover, in the area | region which faces the small edge 53a of the book main body 50 in the seal | sticker main body 10, since the adhesive layer is missing and the seal main body 10 and the small opening 53a do not adhere | attach, the pseudo-adhesion between notches with the surface base material 11 is carried out. The layer 12a peels from the book body 50.
Thus, by peeling off the surface base material 11 and disassembling the seal body 10, the seal body 10 can be removed from the small edge without tearing the seal body 10, and the seal of the book can be easily released. .

<Third Embodiment>
A third embodiment of the book seal sticker according to the present invention will be described.
FIG. 9 shows a seal for book sealing according to this embodiment. Also in this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as those in FIG.
The book sealing seal 3 includes a seal body 10 in which a pseudo adhesive layer 12 and an adhesive layer 13 are sequentially formed on a surface base material 11, and a release sheet 20 laminated on the adhesive layer 13 of the seal body 10. It has.
In the book sealing seal 3, a pair of cuts 30, 30 are formed in the pseudo-adhesive layer 12 and the pressure-sensitive adhesive layer 13 of the seal body 10, and a pair of cuts 30, 30 are formed. A non-adhesive layer 15 is formed on the surface of the agent layer 13 on the release sheet 20 side. Thus, the non-adhesion process which weakens the adhesive force of the adhesive layer 13 is performed by the non-adhesion layer 15 being formed. Here, examples of the non-adhesive layer 15 include UV curable inks, such as white and medium of Daicure RT-V manufactured by Dainippon Ink & Chemicals, Inc.
When sticking the book seal 3 to the book, the non-adhesive layer 15 at the center is placed in the forehead. By disposing the non-adhesive layer 15 in the fore edge, the adhesive layer 13 hardly remains in the fore edge when the seal is released.

Also in the book sealing seal 1 of the third embodiment, as shown in FIG. 10, it is formed on the pseudo-adhesive layer 12 and the pressure-sensitive adhesive layer 13 in the seal body 10 as in the first embodiment. The book can be sealed by sticking the seal body 10 to the book body 50 so that the cuts 30 and 30 extend along the front edge 51a and 52a of the front cover 51 and the back cover 52 of the book body 50.
When unsealing, the surface base material 11 of the seal body 10 is peeled off. At this time, in the sticking region 10b, as shown in FIG. 11, the surface base material 11 peels from the pseudo adhesive layer 12, and the surface base material 11, the pseudo adhesive layer 12b and the adhesive layer 13b of the sticking part are formed. To separate. Moreover, in the area | region which faces the small edge 53a of the book main body 50 in the seal | sticker main body 10, since the surface of the adhesive layer 13a is covered with the non-adhesive layer 15, and the seal main body 10 and the small opening 53a are not adhere | attached, surface base material 11, the pseudo adhesive layer 12 a between the cuts, the pressure-sensitive adhesive layer 13 a, and the non-adhesive layer 15 are peeled off from the book main body 50.
Thus, by peeling off the surface base material 11 and disassembling the seal body 10, the seal body 10 can be removed from the small edge without tearing the seal body 10, and the seal of the book can be easily released. .

(Book sealing method)
Next, the book sealing method of the present invention will be described.
In the book sealing method of the present invention, the release sheet is peeled off from the above-described seal for book sealing, and the adhesive layer 13 of the seal body 10 exposed thereby is attached to the cover 51 of the book body 50 as shown in FIGS. And a method of adhering to the back cover 52. The illustrated example is an example using the seal 1 for book sealing of the first embodiment.
In this sealing method, when the adhesive layer 13 of the seal body 10 is attached to the cover 51 and the back cover 52 of the book body 50, the two cuts 30 and 30 are the cover 51 and the back cover of the book body 50, respectively. The seal body 10 is disposed along the edge 51a, 52a of the edge of the fore edge 52. In the illustrated example, the fore edge is the front fore edge 53a, but the top edge 53b and the fore edge 53c may be used.

In the book sealing method of the present invention, since the pressure-sensitive adhesive layer 13 of the book sealing seal 1 described above is attached to the cover 51 and back cover 52 of the book body 50, the book body 50 can be sealed. Moreover, when the adhesive layer 13 of the seal body 10 is stuck to the book body 50, the two cuts 30 and 30 are sealed so as to follow the edge 51a and 52a of the front cover 51 and the back cover 52, respectively. Since the main body 10 is disposed, the seal can be released by peeling off the surface base material 11 after the seal main body 10 is adhered. That is, when the surface base material 11 is peeled off, the pseudo adhesive layer 12a and the pressure-sensitive adhesive layer 13a between the two cuts 30 and 30 are attached to the book body 50. To separate from 13b, the seal can be released. In addition, since the fore edge usually has unevenness, the pressure-sensitive adhesive layer 13a is not firmly attached to the fore edge.
Further, by releasing the seal in this manner, it is not necessary to tear or peel off the book sealing seal 1, so that the book body 50 can be prevented from being torn and the appearance of the book body 50 can be maintained. When the pressure-sensitive adhesive of the pressure-sensitive adhesive layer 13 does not have removability, the pseudo adhesive layer 12b and the pressure-sensitive adhesive layer 13b remain in the book body 50, but they remain orderly, so that the appearance is sufficiently maintained. .

(Book)
The book of the present invention is sealed by the above-described book sealing method, and as shown in FIG. 12, the seal body 10 of the seal for book sealing is attached to the cover and back cover of the book body 50. It is. The type of book body is not limited and includes, for example, a magazine, a book, a paperback book, a catalog booklet, and the like. Therefore, the magazine sealed by the book sealing method is particularly meaningful.
Since the book of the present invention is sealed by the above-described book sealing method, reading is prevented. Furthermore, since the book purchaser only has to peel off the surface base material when unsealing, it is not only easy, but part of the book is not easily peeled off, and the appearance is not easily impaired.

The present invention will be described in more detail with reference to the following examples, but the present invention is not particularly limited thereto.
Example 1
As shown in FIG. 1, the book seal seal of Example 1 has a pseudo adhesive layer 12 made of LDPE and a pressure-sensitive adhesive layer 13 made of an acrylic water-soluble pressure-sensitive adhesive on a polyester film that is a surface substrate 11 in order. The seal body 10 is formed, and a release sheet 20 made of glassine paper having one side laminated on the adhesive layer 13 of the seal body 10 is a release-treated surface. In the book seal 1, a pair of cuts 30 and 30 are formed in the pseudo adhesive layer 12 and the pressure-sensitive adhesive layer 13 of the seal body 10 with two having a predetermined interval.

Below, the manufacturing method of this seal 1 for book sealing is demonstrated.
LDPE (Sumitomo Chemical Co., Ltd.) is a transparent thermoplastic resin on the untreated surface side of the polyester film (thickness 38 μm, Cosmo Shine A4100 manufactured by Toyobo Co., Ltd.), which is a surface substrate 11 that has been subjected to easy adhesion treatment on one side. ) Sumikasen L405) was laminated in a molten state by an extrusion laminating method to form a pseudo adhesive layer 12. At that time, the resin temperature of LDPE was set to 300 ° C., and the thickness of the pseudo adhesive layer 12 was set to 20 μm by discharging from the T die. Subsequently, the surface of the pseudo adhesive layer 12 was subjected to corona discharge treatment to obtain a printing film. The adhesive strength between the polyester film (surface substrate 11) and the pseudo adhesive layer 12 was 0.2 N / 25 mm.
Next, a silicone release treatment agent was applied to one side of glassine paper (basis weight 62 g, thickness 57 g), and a release treatment surface was provided to obtain a release sheet 20. An acrylic resin-based water-soluble adhesive (AR-2090 manufactured by Big Technos Co., Ltd.) is applied on the release-treated surface of the release sheet 20 so that the thickness after drying is 25 μm, and is heated and dried at 80 ° C. for 2 minutes. Thus, the pressure-sensitive adhesive layer 13 was formed.
Next, the film in which the pressure-sensitive adhesive layer 13 is formed on the release sheet 20 and the above-described printing film are bonded so that the pressure-sensitive adhesive layer 13 and the pseudo adhesive layer 12 are in contact with each other, and then wound. A roll-shaped laminate having a width of 100 mm and a length of 200 m was obtained.

Next, the laminate is delivered from the roll-like laminate, and a slitter provided with a cutting blade and a fixing means for fixing the position of the cutting blade is used. Cuts 30 and 30 were formed in the pressure-sensitive adhesive layer 13 and the pseudo adhesive layer 12 of the main body 10 and part of the surface base material 11 (about 1 to 2 μm in depth from the surface of the pseudo adhesive layer 12 side). The cuts 30 and 30 were formed at two positions 45 mm inside from both ends in the width direction.
Next, printing of an arbitrary design was provided on the easy-adhesion treated surface of the surface substrate 11 with a printing machine. Thereafter, a punching blade was put into the seal body 10 to form a label having an arbitrary shape, and after trimming a blank portion, the seal was wound into a roll to continuously produce a seal for book sealing.

  The release sheet 20 is peeled from the book seal seal 1 obtained in this way, and as shown in FIG. 4, the adhesive layer 13 of the seal main body 10 exposed thereby is formed with notches 30, 30 as a cover 51 and a back cover. The book main body 50 was partially sealed by being attached to the book main body 50 along the edge edges 51a and 52a of the fore edge of 52.

(Example 2)
As shown in FIG. 6, the seal for book sealing of Example 2 includes a seal body 10 and a release sheet 20 made of glassine paper having one side laminated on the adhesive layer 13 of the seal body 10 and having a release-treated surface. It is what you have. In this book seal 2, two seal bodies 10 are formed by forming a pseudo-adhesion layer 12 made of LDPE on an OPP film as a surface base material 11, and having a predetermined interval on the pseudo-adhesion layer 12. Thus, pressure-sensitive adhesive layers 13 and 13 made of a pair of acrylic water-soluble pressure-sensitive adhesives are formed. Further, incisions 30 and 30 are formed at the boundary between the region 12 c in contact with the pressure-sensitive adhesive layer 13 and the region 12 d in non-contact with the pseudo adhesive layer 12 of the seal body 10.

Below, the manufacturing method of this seal 2 for book sealing is demonstrated.
As the surface base material, an OPP film (thickness 50 μm, Oji Paper Co., Ltd. Dialite 50CL-01A), which is a surface base material 11 that has been subjected to easy adhesion treatment on one side, is peeled off. A laminate was produced in the same manner as in Example 1 except that the strip was applied to the release treatment surface of the sheet in a striped manner at a predetermined interval. The adhesive strength between the surface base material 11 and the pseudo adhesive layer 12 was 0.5 N / 25 mm.
Next, after the release sheet 20 was peeled from the laminate, a cut was formed at the boundary between the region 12c in contact with the pressure-sensitive adhesive layer 13 and the region 12d in contact with the pressure-sensitive adhesive layer 13 in the pseudo adhesive layer 12. And the peeling sheet 20 and the adhesive layer 13 were again bonded together, this was wound up, and the seal for book sealing was manufactured continuously.
And the book was sealed like Example 1 using this seal | sticker for book sealing.

(Example 3)
As shown in FIG. 9, the book seal seal of Example 3 has a pseudo adhesive layer 12 made of LDPE and a pressure-sensitive adhesive layer 13 made of an acrylic water-soluble pressure-sensitive adhesive successively on a polyester film that is a surface substrate 11. The seal body 10 is formed, and a release sheet 20 made of glassine paper having one side laminated on the adhesive layer 13 of the seal body 10 is a release-treated surface.
In the book sealing seal 3, a pair of cuts 30, 30 are formed in the pseudo-adhesive layer 12 and the pressure-sensitive adhesive layer 13 of the seal body 10, and a pair of cuts 30, 30 are formed. A non-adhesive layer 15 is formed on the surface of the agent layer 13 on the release sheet 20 side.

Hereinafter, a method for manufacturing the book seal 3 will be described.
After manufacturing a laminated body like Example 1, the peeling sheet 20 is peeled from the laminated body, a cutting blade is put in from the adhesive layer 13 side using a slitter, and the adhesive layer 13 of the seal body 10 is used. In addition, cuts 30 and 30 were formed in the pseudo adhesive layer 12 and a part of the surface base material 11 (depth of about 1 to 2 μm). The cuts 30 and 30 were formed at two positions 45 mm inside from both ends in the width direction.
Next, UV curable offset ink (Dai-Cure RT-V White, manufactured by Dainippon Ink & Chemicals, Inc.) was printed between the cuts 30 and 30 in the pressure-sensitive adhesive layer 13 and on the surface of the release sheet 20 at the end. Thereafter, the release sheet 20 and the pressure-sensitive adhesive layer 13 were bonded to each other after being irradiated with ultraviolet rays and cured to form a non-sticky layer 15 to perform a non-sticking treatment that weakens the pressure-sensitive adhesive force of the pressure-sensitive adhesive layer.
Next, printing of an arbitrary design was provided on the easy-adhesion treated surface of the surface base material with a printer. Thereafter, a punching blade was inserted into the seal body 10 to form a label having an arbitrary shape, and after trimming the blank portion, the seal was wound into a roll to continuously produce a seal for sealing a book.
The release sheet is peeled from the book seal seal thus obtained, and the adhesive layer of the seal body exposed thereby is attached to the book so that the cut is along the edge of the front cover and the back cover. Partially sealed the book.

Example 4
The book seal seal of Example 4 has the same layer structure as that of Example 2, but the adhesive layer 13 is formed by silk screen printing. That is, patterns 13c and 13d are formed on the adhesive layer 13 as shown in FIG.

A printing film was produced in the same manner as in Example 1, and cuts 30 and 30 were formed in the pseudo adhesive layer 12 of the printing film and part of the surface base material 11 (depth of about 1 to 2 μm). The cuts 30 and 30 were formed at two positions 45 mm inside from both ends in the width direction.
Next, after the printed film was processed into a flat (sheet) shape having a predetermined size, a mesh silk screen on which an arbitrary pattern or character pattern was formed was placed on the pseudo adhesive layer 12. Next, an adhesive for silk screen printing (CAT-1300S manufactured by Teikoku Ink Manufacturing Co., Ltd.) was applied from the through hole of the silk screen so that the thickness after drying was 25 ± 5 μm, and heated at 80 ° C. for 2 minutes. It dried and the adhesive layer 13 was formed. However, no adhesive was applied to the pseudo adhesive layer 12 between the two cuts 30 and 30.
Next, double-sided polyethylene laminated kraft paper (basis weight 110 g) having a release treatment on one side was bonded to the pressure-sensitive adhesive layer 13.
Further, the surface of the surface substrate 11 opposite to the pseudo-adhesive layer 12 was subjected to arbitrary printing or glossing processing (varnish coating or PP dry laminating) with a silk screen printing machine or a sheet-fed offset printing machine. Thereafter, a punching blade was put into the seal body 10 to form a label having an arbitrary shape, and after trimming a blank portion, the seal was wound into a roll to continuously produce a seal for book sealing.
Then, like Example 1, the book was partially sealed using the obtained seal for sealing a book.

(Example 5)
As an adhesive of an adhesive layer, the isocyanate type hardening | curing agent L-45 and 1.5 mass part are contained with respect to 100 mass parts of acrylic adhesives (SK Dyne "SK-1717" by Soken Chemical Co., Ltd.). A seal for book sealing was produced in the same manner as in Example 1 except that the pressure-sensitive adhesive composition was used.
And the book was sealed like Example 1 using this seal | sticker for book sealing.

(Example 6)
An OPP film (thickness 50 μm, Oji Paper Co., Ltd. Dialite 50CL-01A), which is a surface base material 11 that has been subjected to easy adhesion treatment on one side, was prepared in advance on its untreated side. A 5% aqueous solution of carboxymethyl cellulose “Sunrose FT-3” manufactured by Nippon Paper Chemical Co., Ltd. was applied so that the film thickness after drying was 5 μm, and dried at 100 ° C. for 8 minutes to form a pseudo adhesive layer 12. Thus, a film for printing was obtained. The adhesive strength between the surface base material 11 and the pseudo adhesive layer 12 was 0.1 N / 25 mm. Then, the subsequent steps were performed in the same manner as in Example 1 to obtain a book sealing seal 1.
And the book was sealed like Example 1 using this seal | sticker for book sealing.

(Comparative Example 1)
One side of glassine paper (basis weight 62 g, thickness 57 g) is subjected to a release treatment with a silicone release treatment agent to form a release treatment surface, and an acrylic resin water-soluble adhesive (Big Technos Co., Ltd.) is formed on the release treatment surface. AR-2090) was applied so that the thickness after drying was 25 μm to form an adhesive layer. Then, the pressure-sensitive adhesive layer is bonded to the untreated surface side of a polyester film (thickness 38 μm, Cosmo Shine A4100 manufactured by Toyobo Co., Ltd.), which is a surface base material that has been subjected to easy adhesion treatment on one side, and no cut is formed. Produced a seal for book sealing.
The release sheet was peeled from the book seal seal, and the pressure-sensitive adhesive layer thus exposed was stuck to the book so that the sticking areas on the front cover and the back cover were substantially uniform, and the book was partially sealed.

About the said Examples 1-6 and the comparative example 1, it evaluated as follows. The evaluation results are shown in Table 1.
<Measurement method of adhesive strength of pseudo adhesive layer>
In accordance with JIS Z 0237 (2000 version), five test specimens having a width of 25 mm and a length of about 120 mm were cut out. The cut sample piece was allowed to stand in an environment of 23 ° C. × 50% for 1 hour or longer to adjust to the atmosphere. Then, using a Tensilon universal tester “RTA-100” manufactured by A & D as a measuring machine, the pseudo adhesive layer was peeled from the surface base material at a rate of 300 mm / min in the direction of 180 degrees, and the stress at that time was measured. The average value was obtained.

<Measurement method of adhesive strength of pressure-sensitive adhesive layer>
In accordance with JIS Z 0237 (2000 version), five test pieces having a width of 25 mm and a length of about 100 mm with an adhesive on the entire surface were cut out. The cut sample piece was allowed to stand in an environment of 23 ° C. × 50% for 1 hour or longer and acclimatized to the atmosphere, and then attached to the adherend and left at 23 ° C. × 50% for 30 days. Then, using a Tensilon universal testing machine “RTA-100” manufactured by A & D as a measuring machine, the test piece was peeled off from the adherend at a rate of 300 mm / min in the direction of 180 degrees, and the stress at that time was measured. The average value was obtained.
In addition, since the measurement of adhesive strength is difficult for a test piece with a pseudo-adhesive layer, it was performed using a material in which an adhesive was directly applied to the surface substrate 11.

<Removability>
The release sheet was peeled off from each book-sealing seal, and the exposed adhesive layer of the seal body was attached to a weekly magazine so that the cut edge would be along the edge of the front and back cover as well as across the front edge and sealed. . Then, the weekly magazine sealed with the seal for book sealing was left for 30 days in an environment of 23 ° C. × 55%, and then the surface base material of the seal body was peeled off by hand. At that time, in Examples 1 to 6, the pseudo adhesive layer and the pressure-sensitive adhesive layer between the cuts were separated while peeling at the interface between the surface base material and the pseudo adhesive layer. On the other hand, in the comparative example 1, it peeled between the adhesive layer of the seal for book sealing, and the cover and back cover of a weekly magazine.
In this peeling, the case where the weekly magazine was not torn was evaluated as ◯, and the case where it was broken was evaluated as x. Moreover, when the weekly magazine was not contaminated by the seal for sealing the book, it was evaluated as “good”, and when the weekly magazine was contaminated, it was evaluated as “poor”.

<Method for testing water solubility of adhesives>
A seal specimen for sealing a book with a known pressure-sensitive adhesive mass was prepared, and a seal for book sealing was pasted on the cover and back cover of a weekly magazine that had been printed with ink on the paper, and left at 23 ° C. for 30 days. Then, immerse the cover of the weekly magazine with the book seal sticker in the tap water adjusted to a temperature of 25 ± 5 ° C with the cover, and make sure that the stirring blade does not come into contact with the cover with a lab stirrer. The mixture was stirred for 1 hour at the rotation speed. At that time, the pressure-sensitive adhesive-coated surface of the removed book seal seal was visually observed. And after taking out the taken-out seal | sticker test piece with the dryer around 80 degreeC for 1 hour, seal mass was measured and the residual rate of the adhesive was calculated.

In Examples 1, 5, and 6 that satisfy the scope of claim 1 of this application, Examples 2 and 4 that satisfy the scope of claim 2 of this application, and Example 3 that satisfies the scope of claim 3 of this application, the adhesive strength of the adhesive layer is Because it is secured enough, the weekly magazine can be sealed. Moreover, since the adhesive strength between the surface base material and the pseudo adhesive layer is weak, the surface base material can be easily peeled off and the seal can be released. Furthermore, in Examples 1-6, damage and contamination of the weekly magazine were prevented. Moreover, in Examples 1 to 3 and 6, water-soluble adhesives are used, so that the recyclability is excellent.
On the other hand, in Comparative Example 1 having the same configuration as that of a general pressure-sensitive adhesive sheet, although sealing is possible, it was difficult to peel off the pressure-sensitive adhesive sheet from the weekly magazine.
