Description

  The present invention relates to an information sheet capable of being adsorbed or adhered to various adherends. The present invention also relates to an information display in which the information sheet is adsorbed or adhered to the adherend.

  Conventionally, when affixing a sheet-like medium such as a poster or advertisement produced by printing on a hard adherend such as a wall surface, a glass surface, a pillar, a bulletin board, a locker, or a bookshelf, an adhesive, an adhesive tape or the like is used. It has In recent years, from the viewpoint of material recycling, there is also a demand for sheet media such as advertisements that can be easily recovered in a reusable state even after use. However, when an adhesive or a double-sided tape is used, it is not easy to separate an advertisement or the like from an adherend, and it may be broken and it can not be reused. In addition, if an adhesive or adhesive remains in an advertisement etc., it becomes difficult to recycle as a resource, and as a result, there is a problem that the majority is treated as waste after being used once. Furthermore, when a sheet-like medium such as an advertisement is attached to an adherend such as a wall surface or a column using an adhesive or double-sided tape, glue or the like may remain on the adherend side after it is peeled off, There is also a problem that the coating on the surface of the adherend may be peeled off.

  On the other hand, there has been proposed a technique for attaching a sheet-like medium such as an advertisement to an adherend by electrostatic attraction (see Patent Document 1 below). Patent Document 1 describes a sheet in which a support layer and an opaque label layer are electrostatically adsorbed to each other, and the label layer is peeled off from the support layer during use, and the surface is peeled off and exposed. It has been described that the label layer is attached and electrostatically adsorbed so that it contacts the adherend surface. According to Patent Document 1, since the sheet before peeling does not express electrostatic adsorption force to the outside before peeling, there is an advantage that troubles such as sticking to a roll or blocking of sheets are hard to occur especially in the printing process. In addition, it is said that the handling property is good and it can cope with various printing methods. Further, according to Patent Document 1, after being attached to the adherend, there is an advantage that the electrostatic adsorption force is sustained for a long period without being influenced by the environmental humidity, and it can be easily peeled off after use. It is assumed.

Unexamined-Japanese-Patent No. 2012-145935

  However, in the sheet of Patent Document 1, there is a problem that the support layer remains at hand after peeling off the label layer from the sheet to be attached to the adherend. For this reason, after sticking a label layer to a to-be-adhered body, the support body layer was collect | recovered, and the effort of carrying and processing was taken. Therefore, it has been desired to avoid the situation where a large amount of waste material is released.

  On the other hand, it is required to print various information in the label layer, but in the case of information including a map among others, printing in which various information according to the individual purpose is added based on a common map It is often required to do For example, printing that indicates a place such as a store, printing that indicates a route to a destination, etc. is performed by printing a common map and additionally printing, or modifying a common map from the original and printing ing. However, in order to meet various needs, it is inefficient and time-consuming to print a map added with information meeting each need each time. Therefore, it is convenient if there is a sheet that can easily add individual information corresponding to each need to the map while using the map itself in common. However, such convenient sheets have not been developed.

  In addition, passers and the like often touch the map displayed as a display body with a finger. For this reason, printing at specific points such as important places and destinations is often thinner or peeled off than others. Therefore, appropriate protection of the displayed map was also required.

  The present inventors diligently studied to solve the above-mentioned problems of the prior art. As a result, a sheet is prepared in which a transparent film layer and an opaque film layer printed with information are adsorbed or adhered, and the transparent film remains after peeling off the opaque film layer and attaching it to an adherend during use. We found that the problem could be solved by pasting layers on information. If the additional information is printed on the transparent film layer, the additional information is displayed on the information when the transparent film is attached on the information, and the information corresponding to the individual needs can be displayed. Further, additional information can be added to the transparent film layer by a marker or the like.

Thereby, the surface 12A of the opaque film layer 12 and the surface 16A of the first transparent film layer 16 adhere to each other via the first adhesive layer 13, the release layer 14 and the second adhesive layer 15.
As shown in FIG. 3, the opaque film layer 12 may be formed of only a single resin layer (first resin layer), or a recording layer may be separately provided on the resin layer to provide information 4 on the recording layer. It is good also as an aspect which has. In addition, the first transparent film layer 16 may be formed of only a single resin layer (second resin layer), or may be a multilayer structure configured of a plurality of resin layers and the like.

  Such an adhesive information sheet 11 may be any one of a first adhesive layer 13 provided on one surface of a first resin layer and a second adhesive layer 15 provided on one surface of a second resin layer.

The peeling surface 13A of the first adhesive layer 13 is a surface that causes the opaque film layer 12 to adhere to the adherend when the information display body is formed. Next, as shown in FIG. 4 (b), the peeling layer 14 is peeled off from the second adhesive layer 15 provided on the first transparent film layer 12. The peeling surface 15A of the second adhesive layer 15 is a surface that causes the first transparent film layer 16 to adhere on the information 4 of the opaque film layer 12 when configuring the information display body. The first transparent film layer 16 can function as a protective film for protecting the information 4 when the information sheet 11 is used as an information display body.

Next, another example of the adhesion information sheet to which the present invention is applied will be described. FIG. 5 is a cross-sectional view showing another example of the laminated structure of the adhesion information sheet to which the present invention is applied. As shown in FIG. 5, the information sheet 17 is a laminate including an opaque film layer 12, a first adhesive layer 13, a first transparent film layer 16, a second adhesive layer 15, and a release layer 14. I have a body. Information 4 is provided on one surface (surface 12 B) of the opaque film layer 12.
In this adhesive information sheet 17, the first adhesive layer 13 is provided on the surface 12A opposite to the surface 12B of the opaque film layer 12 having the information 4. Then, the surface 16A of the first transparent film layer 16 is adhered to the surface (peeling surface 13A) opposite to the surface of the first adhesive layer 13 in contact with the opaque film layer 12. Thereby, the surface 12A of the opaque film layer 12 and the surface 16A of the first transparent film layer 16 adhere to each other through the first adhesive layer 13. In addition, the second adhesive layer 15 is provided on the surface 16B opposite to the surface 16A on the opaque film layer 12 side of the first transparent film layer 16, and the first transparent film of the second adhesive layer 15 is provided. The peeling layer 14 is laminated on the surface (peeling surface 15A) opposite to the surface in contact with the layer 16. This prevents dust and the like from adhering to the peeling surface 15A of the second adhesive layer 15.
As shown in FIG. 5, the opaque film layer 12 may be formed of only a single resin layer (first resin layer), or a recording layer may be separately provided on the resin layer to provide information 4 on the recording layer. It is good also as an aspect which has. In addition, the first transparent film layer 16 may be formed of only a single resin layer (second resin layer), or may be a multilayer structure configured of a plurality of resin layers and the like.

  Such an adhesive information sheet 17 has a second resin layer in which the second adhesive layer 15 is provided on one side on the first adhesive layer 13 provided on one side of the first resin layer. A step of laminating so that the surface opposite to the surface on which the second adhesive layer 15 is provided is in contact with the first adhesive layer 13, and a surface of the second adhesive layer 15 in contact with the second resin layer Is manufactured by the steps of laminating the release layer 14 on the opposite side and applying the information 4 to the side opposite to the side on which the first adhesive layer 13 of the first resin layer is provided. it can.

  The usage method of the adhesion information sheet 17 shown in FIG. 5 is demonstrated. FIG. 6 is a cross-sectional view for explaining how to use the adhesion information sheet 17 shown in FIG. When the adhesive information sheet 17 is made to adhere to the adherend, first, as shown in FIG. 6A, from the first adhesive layer 13 of the adhesive information sheet 17 to the first transparent film layer 16 and the second transparent film layer. By peeling off the laminate composed of the adhesive layer 15 and the release layer 14, the opaque film layer 12 and the first transparent film layer 16 are separated. A first adhesive layer 13 is provided on the side 12A opposite to the information-bearing side 12B of the separated opaque film layer 12. The peeling surface 13A of the first adhesive layer 13 is a surface that causes the opaque film layer 12 to adhere to the adherend when the information display body is formed. Next, as shown in FIG. 6 (b), the peeling layer 14 is peeled off from the second adhesive layer 15 provided on the first transparent film layer 16.

The first transparent film layer 16 can function as a protective film for protecting the information 4 when the information sheet 17 is used as an information display body.

(Negative pressure adsorption information sheet)
Next, a negative pressure adsorption information sheet will be described as still another example of the information sheet of the present invention. As a laminate structure of the negative pressure adsorption information sheet, a first adsorption layer is provided on the opaque film layer 12 instead of the first adhesive layer 13, and a second adsorption layer is used instead of the second adhesive layer 13. A laminated structure similar to that of the adhesion information sheets 11 and 17 described above is employed except that it is provided in the first transparent film layer 16 and these adsorption layers and the layers in contact with these adsorption layers are adsorbed by negative pressure. be able to. In addition, the first adhesive layer 13 and the second adhesive layer 15 are also the first adsorption layer and the second adsorption layer in the production method and the usage method thereof, and adsorption by negative pressure is used instead of adhesion. Except for the above, the manufacturing method and the using method of the above-mentioned adhesion information sheets 11 and 17 are the same, and the description of these can be referred to.
A porous layer can be used as an adsorption layer which expresses negative pressure. For example, when the first transparent film layer, peeling layer, resin film layer, adherend or the like is brought into pressure contact with the porous layer, the air in each hole of the porous layer is partially exhausted and the inside of each hole is negative. It becomes pressured. Thereby, these substances are adsorbed to the porous layer by negative pressure. The material and composition of the porous layer will be described later.
The information sheet of the present invention as described above is a mode before being adsorbed to an adherend such as a wall surface, a glass surface, a pillar, a bulletin board, a locker, a bookshelf, etc. to make an information display body. This is a mode suitable for time of sale, etc.

(Information indicator)
An example of the information display body of the present invention will be described. FIG. 7 is a cross-sectional view showing an example of the laminated structure of the information display body of the present invention. The same reference numerals are given to members in FIG. 7 which are the same as in FIG. 1 and FIG. As shown in FIG. 7, the information display body has a structure in which the laminate 10 including the resin film layer 2 ′ and the first transparent film layer 3 is electrostatically adsorbed on the adherend 5. The resin film layer 2 ′ includes the first resin layer, and the information 4 is given to one surface (surface 2B) of the resin film layer 2 ′. And peeling surface 3A of the 1st transparent film layer 3 is electrostatically adsorbed on the surface (surface 2B) which has the information 4 of resin film layer 2 '. The resin film layer 2 in the information display body of the present invention may be transparent or opaque, and is a concept including the opaque film layer in the information sheet of the present invention. Therefore, the first resin layer constituting the resin film layer 2 ′ may be the same as the first resin layer constituting the opaque film layer.

  For this reason, after the first transparent film layer 3 is peeled off from the opaque film layer 2 as described above, the information display body of FIG. 7 covers the peeling surface 2A of the opaque film layer 2 charged by static electricity. It can be produced by adsorbing to the adherend 5 and further adsorbing the peeling surface 3 A of the first transparent film layer 3 charged by static electricity onto the information 4 of the opaque film layer 2. The information 4 can be visually recognized through the first transparent film layer 3 by observing from the surface 3B side. In the information display body of FIG. 7, the information 4 is protected by the first transparent film layer 3. In addition, since the laminate 10 is adsorbed to the adherend 5 by static electricity, the glue remains on the adherend 5 when it is peeled off from the adherend 5 and recovered after it plays a role as an information display. It can be easily peeled off without peeling off or peeling off the coating on the surface. Further, since the surface 3B of the first transparent film layer 3 which is the outermost surface of the laminate 10 is not charged by static electricity, it is possible to suppress adhesion of dust and the like due to the static electricity.

Another example of the information display body of the present invention will be described. FIG. 8 is a cross-sectional view showing another example of the laminated structure of the information display body of the present invention. The same reference numerals as in FIGS. 3 to 6 denote the same members in FIG. 8 and a description thereof will be omitted.
As shown in FIG. 8, in the information display body, the laminate 20 including the first adhesive layer 13, the resin film layer 12 ′, the second adhesive layer 15, and the first transparent film layer 3 is covered. It has a structure in which the adherend 5 adheres. The resin film layer 12 ′ includes the first resin layer, and the information 4 is given to one surface (surface 12B) of the resin film layer 12 ′. Then, one surface 16A (or 16B) of the first transparent film layer 16 is adhered via the second adhesive layer 15 on the surface (the surface 12B) of the resin film layer 12 'having the information 4 . The resin film layer 12 'in the information display body of the present invention may be transparent or opaque, and is a concept including the opaque film layer in the information sheet of the present invention. Therefore, the first resin layer constituting the resin film layer 12 ′ may be the same as the first resin layer constituting the opaque film layer.

Such an information display body can be manufactured, for example, by using the information sheet (adhesion information sheet) 11, 17 of the present invention shown in FIG. 3 and FIG.
In order to manufacture the information display body, first, the laminate including the release layer 14, the second adhesive layer 15, and the first transparent film layer 16 is peeled off from the first adhesive layer 13 of the adhesive information sheets 11 and 17. Thus, after the opaque film layer 12 and the first transparent film layer 16 are separated, the peeling surface 13A of the first adhesive layer 13 provided on the opaque film layer 12 is made to adhere to the adherend 5. Furthermore, the peeling layer 14 is peeled off from the second adhesive layer 15 provided on the first transparent film layer 16, and the peeling surface 15 A of the second adhesive layer 15 is adhered on the information 4 of the opaque film layer 12. It can be produced by Here, in the case where the adhesion information sheet 11 shown in FIG. 3 is used as the information sheet, on the side of the opaque film layer 12 in the adhesion information sheet 11 among the surfaces 16A and 16B of the first transparent film layer 16 It becomes an aspect which comprises the surface 16B on the opposite side which constitutes the outer surface (surface opposite to the surface on the resin film side) of the information display body. Moreover, when the adhesion information sheet 17 shown in FIG. 5 was used as an information sheet, it was on the opaque film layer 12 side in the adhesion information sheet 17 among each surface 16A, 16B of the 1st transparent film layer 16. The surface 16A constitutes an aspect in which the outer surface of the information display body (surface opposite to the surface on the resin film layer 12 'side) is configured.
The information 4 is viewed through the first transparent film layer 16 by observing from the side 16B (or 16A) opposite to the surface of the first transparent film layer 16 on the resin film layer 12 ′ side. Can. In the information display body of FIG. 6, the information 4 is protected by the first transparent film layer 16.

  Further, in the information display body of the present invention, in the information display body shown in FIG. 8, a first adsorption layer is provided instead of the first adhesive layer 13, and a second adsorption instead of the second adhesive layer 15. The information display body in which the layer is provided, and the negative pressure generated by each adsorption layer causes the first adsorption layer to adsorb the adherend and the second adsorption layer to adsorb on the information of the opaque film layer It may be Such an information display body is provided with a first adsorption layer instead of the first adhesion layer 13 and a second adsorption layer instead of the second adhesion layer 15 in the adhesion information sheet shown in FIG. 3 or 5. It can manufacture by the process similar to, when using the adhesion information sheet shown in FIG. 3 or FIG. 5 using the negative pressure information sheet provided. In such an information display body, since the laminate is adsorbed to the adherend by negative pressure, the glue remains on the adherend side when it is peeled off from the adherend after it plays a role as an information display body. It can be easily peeled off without peeling off or peeling off the coating on the surface.

The manufacturing method of the information display body of the present invention is not limited to the method described above, and the manufacturing method is not particularly limited as long as it has the same structure.

[Opaque film layer]
The opaque film layer which comprises the information sheet of this invention contains a 1st resin layer, and has information in one side. In the present invention, the opaque film layer means a layer having an opacity of 50 to 100%. If the opacity is 50% or more, when used as a label, there is an advantage that the coloring of an object to be deposited, a pattern or a pattern can not be seen through. The opacity of the opaque film layer is preferably 60 to 100%, more preferably 70 to 100%. In the present invention, the opacity is based on JIS-P-8138, and a black and white standard plate is applied to the back of the measurement, and the light reflectance ratio (black plate / white plate) is indicated by a percentage Ru.
In addition, the resin film layer of the information display body of this invention can also be made into the structure similar to the opaque film layer in the information sheet of this invention.

  The thickness of the opaque film layer is preferably 20 to 500 μm, more preferably 25 to 400 μm, still more preferably 30 to 200 μm, and particularly preferably 40 to 150 μm. When the thickness of the opaque film layer is 20 μm or more, when the opaque film layer is attached to the adherend, it is difficult to get wrinkles and it is easy to attach. Also, if the thickness of the opaque film layer is 500 μm or less, the weight of the opaque film layer is not too large, and it can not hold its own weight due to electrostatic adsorption force or other adsorptive force or adhesive force and falls from the adherend It is possible to prevent it.

[First resin layer]
The first resin layer in the present invention constitutes an opaque film layer. In the case where the opaque film layer is to be attached to the adherend by electrostatic adsorption, the first resin layer is further subjected to a charging treatment to hold an internal charge, and the electrostatic adsorption causes the opaque film It is possible to attach the layer as a display to the adherend.
The first resin layer of the present invention preferably contains a thermoplastic resin. In particular, by using a thermoplastic resin having excellent insulation properties as the first resin layer of the opaque film layer to be attached by the electrostatic adsorption force, it is preferable to easily retain the charge accumulated therein.

The kind in particular of the thermoplastic resin used for the 1st resin layer is not restricted, but resin illustrated below can be used suitably. These resins can be suitably used particularly for the first resin layer of the opaque film layer to be attached by electrostatic attraction. Specifically, as the resin of the first resin layer, polyolefin resin such as high density polyethylene, medium density polyethylene, low density polyethylene, propylene resin, polymethyl-1-pentene, ethylene / vinyl acetate copolymer, ethylene・ Functional group-containing polyolefin resin such as acrylic acid copolymer, maleic acid modified polyethylene and maleic acid modified polypropylene, polyamide resin such as nylon-6 and nylon-6,6, polyethylene terephthalate and copolymers thereof, polybutylene Thermoplastic polyester resins such as terephthalate and aliphatic polyester, polycarbonate, atactic polystyrene, syndiotactic polystyrene and the like can be used.

As a more specific example of a functional group containing polyolefin resin, the copolymer of the said olefins and the functional group containing monomer which can be copolymerized is mentioned. Such functional group-containing monomers include styrene, styrenes such as α-methylstyrene, vinyl acetate, vinyl alcohol, vinyl propionate, vinyl butyrate, vinyl pivalate, vinyl caproate, vinyl laurate, vinyl stearate, benzoic acid Vinyl, carboxylic acid vinyl esters such as vinyl butylbenzoate, cyclohexanecarboxylic acid vinyl, acrylic acid, methacrylic acid, methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, hexyl (meth) acrylate, octyl (Meth) acrylate, 2-ethylhexyl (meth) acrylate, stearyl (meth) acrylate, benzyl (meth) acrylate, cyclohexyl (meth) acrylate, isobonyl (meth) acrylate, dicyclo (Meth) acrylic esters such as ntanyl (meth) acrylate, (meth) acrylamide, N-metalol (meth) acrylamide, methyl vinyl ether, ethyl vinyl ether, propyl vinyl ether, butyl vinyl ether, cyclopentyl vinyl ether, cyclohexyl vinyl ether, benzyl vinyl ether, phenyl Vinyl ethers such as vinyl ethers are particularly representative. Among these functional group-containing monomers, one or two or more kinds may be appropriately selected and copolymerized as needed.
Further, these polyolefin resins and functional group-containing polyolefin resins can be graft-modified and used if necessary.

  A known technique can be used for graft modification, and specific examples include graft modification with unsaturated carboxylic acid or its derivative. Examples of the unsaturated carboxylic acid include acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid and the like. In addition, acid anhydrides, esters, amides, imides, metal salts and the like can also be used as the above-mentioned derivatives of unsaturated carboxylic acids. Specifically, maleic anhydride, itaconic anhydride, citraconic anhydride, methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, glycidyl (meth) acrylate, monoethyl maleate maleic acid Maleic acid diethyl ester, fumaric acid monomethyl ester, fumaric acid dimethyl ester, itaconic acid monomethyl ester, itaconic acid diethyl ester, (meth) acrylamide, maleic acid monoamide, maleic acid diamide, maleic acid-N-monoethylamide, maleic acid -N, N-diethylamide, maleic acid-N-monobutylamide, maleic acid-N, N-dibutylamide, fumaric acid monoamide, fumaric acid diamide, fumaric acid-N-monoethylamide, fumaric acid -N, N- Diethylamide, fumaric acid-N-mo Butylamide, fumaric acid -N, N- dibutylamide, maleimide, N- butyl maleimide, N- phenylmaleimide, (meth) sodium acrylate, and (meth) potassium acrylate. The graft modified product is generally a graft monomer graft modified with 0.005 to 10% by weight, preferably 0.01 to 5% by weight based on the polyolefin resin and the functional group-containing polyolefin resin.

  Among these thermoplastic resins, it is preferable to use a polyolefin resin excellent in insulation and processability, and a functional group-containing polyolefin resin. As a thermoplastic resin of a 1st resin layer, 1 type may be selected from said thermoplastic resins, and may be used independently, and 2 or more types may be selected and combined and used. Furthermore, among these polyolefin resins, propylene resins are preferable from the viewpoint of insulation, processability, chemical resistance, cost and the like. The propylene-based resin is a propylene homopolymer, polypropylene that exhibits isotactic or syndiotactic and various degrees of stereoregularity, and propylene as a main component, together with ethylene, 1-butene, 1- It is desirable to use a copolymer obtained by copolymerizing an alpha-olefin such as hexene, 1-heptene and 4-methyl-1-pentene as the main component. The copolymer may be a binary system, a ternary system or more, and may be a random copolymer or a block copolymer. It is preferable to mix and use 2-25 mass% resin whose melting | fusing point is lower than a propylene homopolymer to propylene-type resin. As such low melting point resin, high density to low density polyethylene can be exemplified.

  The thermoplastic resin used for the first resin layer in the present invention may be one to which at least one of the inorganic fine powder and the organic filler exemplified below is added. By the addition of the inorganic fine powder and the organic filler and the stretching step described later, it becomes easy to form pores inside the first resin layer. The total amount of the thermoplastic resin blended in the first resin layer is preferably 50 to 100% by mass, and more preferably 60 to 100% by mass. If the compounding amount is 50% by mass or more, it is easy to form the first resin layer, and the charge is easily held in the thermoplastic resin in the first resin layer to be obtained.

  When an inorganic fine powder is added, one having an average particle diameter of usually 0.01 to 15 μm, preferably 0.1 to 5 μm, which is measured by a particle size distribution analyzer by laser diffraction is used. Specifically, calcium carbonate, calcined clay, silica, diatomaceous earth, clay, talc, titanium oxide, barium sulfate, alumina, zeolite, mica, sericite, bentonite, sepiolite, vermiculite, dolomite, wollastonite, glass fiber Etc can be used.

  When an organic filler is added, it is preferable to select a type of resin different from the thermoplastic resin that is the main component of the first resin layer. For example, when the thermoplastic resin is a polyolefin resin, as the organic filler, polymers such as polyethylene terephthalate, polybutylene terephthalate, polycarbonate, nylon-6, nylon-6,6, cyclic polyolefin, polystyrene, polymethacrylate, etc. It is possible to use one having a melting point (for example, 170 to 300 ° C.) to a glass transition temperature (for example, 170 to 280 ° C.) higher than the melting point of the polyolefin resin and being incompatible.

  If necessary, a heat stabilizer (antioxidant), a light stabilizer, a dispersant, a lubricant and the like can be added to the first resin layer. When a heat stabilizer is added, it is usually added in the range of 0.001 to 1% by mass. Specifically, sterically hindered phenol type, phosphorus type, amine type stabilizers and the like can be used. When a light stabilizer is used, it is usually used in the range of 0.001 to 1% by mass. Specifically, light stabilizers such as sterically hindered amines, benzotriazoles, and benzophenones can be used. Dispersants and lubricants are used, for example, for the purpose of dispersing inorganic fine powders. The amount used is usually in the range of 0.01 to 4% by mass. Specifically, silane coupling agents, higher fatty acids such as oleic acid and stearic acid, metal soaps, polyacrylic acids, polymethacrylic acids or salts thereof can be used.

  The thickness of the first resin layer is preferably 20 to 500 μm, more preferably 30 to 400 μm, and still more preferably 40 to 300 μm. When the thickness of the first resin layer is 20 μm or more, when handling the first resin layer alone, it is difficult to stick to the hand or the like due to charging, and the workability can be improved. Moreover, when it affixes to a to-be-adhered body, it does not become wrinkled easily, and it is excellent in external appearance. In addition, when the thickness is 500 μm or less, the weight of the first resin layer is not too large, and it is possible to prevent the first resin layer from falling from the adherend without being able to hold the weight by electrostatic attraction.

[Multilayer]
The first resin layer may have a two-layer structure or a multilayer structure of three or more layers, and the number of stretching axes of this multilayer structure is uniaxial / uniaxial, uniaxial / biaxial, biaxial / biaxial , 1 axis / 1 axis / 2 axes, 1 axis / 2 axes / 1 axis, 2 axes / 1 axis / 1 axis, 1 axis / 2 axes / 2 axes, 2 axes / 2 axes / 1 axis, 2 axes / 2 It may be an axis or an axis. The multi-layering of the first resin layer makes it possible to improve the withstand voltage performance and to add various functions such as writability, abrasion resistance, and secondary processing suitability.
When making a 1st resin layer into multilayer structure, well-known various methods can be used and the method illustrated below can be used suitably. Specific examples thereof include a multilayer die system using a feed block and a multi manifold, and an extrusion lamination system using a plurality of dies. It is also possible to use a combination of multilayer die and extrusion lamination.

[Stretch]
The first resin layer preferably includes a stretched resin film layer stretched at least in one axial direction. Stretching of the resin film layer can be performed by any of various methods commonly used.
The stretching temperature can be carried out within a known temperature range suitable for thermoplastic resins mainly used in the first resin layer but not lower than the glass transition temperature of the thermoplastic resin and not higher than the melting point of the crystal part.
Specifically, when the thermoplastic resin of the first resin layer is a propylene homopolymer (melting point 155 to 167 ° C.), it is 100 to 166 ° C., and when the high density polyethylene (melting point 121 to 136 ° C.) is 70 to 135 It is a temperature which is 1 ° C to 70 ° C lower than the melting point. The stretching speed is preferably 20 to 350 m / min.

As a stretching method, longitudinal stretching using circumferential speed difference of rolls, transverse stretching using a tenter oven, sequential biaxial stretching combining longitudinal stretching and transverse stretching, rolling, simultaneous 2 by combination of a tenter oven and a linear motor Axial stretching, simultaneous biaxial stretching by a combination of a tenter oven and a pantograph, and the like can be mentioned. Moreover, as a stretching method of an inflation film, the simultaneous biaxial stretching by a tubular method can be mentioned.
The stretching ratio is not particularly limited, and is appropriately determined in consideration of the characteristics and the like of the thermoplastic resin used for the first resin layer. For example, when using a propylene homopolymer or copolymer as a thermoplastic resin and stretching it in one direction, it is about 1.2 to 12 times, preferably 2 to 10 times, and in the case of biaxial stretching The ratio is 1.5 to 60 times, preferably 4 to 50 times in area magnification. When another thermoplastic resin is used and stretched in one direction, it is 1.2 to 10 times, preferably 2 to 5 times, and in the case of biaxial stretching, 1.5 to 10 in area ratio It is 20 times, preferably 4 to 12 times.

The first resin layer thus obtained has a large number of fine pores in the film, and the porosity calculated by the following formula (1) is preferably 5 to 60%, More preferably, it is 10 to 45%. By the presence of the pores, the number of interfaces in the resin film is increased, and the charge can be easily held inside. When this is compared with a resin film having no pores, the performance capable of accumulating electric charge is improved, so that the decrease in the adsorption performance is small even in a high humidity environment. In addition, it is possible to obtain the first resin layer having high opacity by the effect of improving the light diffusivity by the holes.

The surface resistivity of the surface of the first resin layer not provided with information is preferably in the range of 1 × 10 ^{13 to} 9 × 10 ¹⁷ Ω. The surface resistivity is more preferably in the range of 5 × 10 ^{13 to} 9 × 10 ¹⁶ Ω, and still more preferably in the range of 1 × 10 ^{14 to} 9 × 10 ¹⁵ Ω. If the surface resistivity is less than 1 × 10 ¹³ Ω, the charge travels through the surface and escapes during the charging process described later, so the efficiency of charge injection to the first resin layer is reduced and the charge is excessive for the charging process. Energy is required, or the effect of the charging process can not be obtained, resulting in low electrostatic adsorption performance. On the other hand, if it exceeds 9 × 10 ¹⁷ Ω, there is no problem as a function of the first resin layer, but it is difficult to form such a highly insulating surface using currently known materials, Even if it can be realized, it is not realistic because of high cost. To make the surface resistivity of the first resin layer not provided with the recording layer a desired range, it is possible to use a polyolefin resin excellent in insulation as a thermoplastic resin, and to use inorganic fine powder to be blended with this. This can be achieved by adjusting the type and amount.

[Recording layer]
The opaque film layer which comprises the information sheet of this invention can provide a recording layer in the single side | surface of the above-mentioned opaque film layer. The recording layer imparts antistatic properties to the opaque film layer, thereby making it difficult to cause troubles in the printing process to improve the handling property and improve the adhesion of the opaque film layer to the printing ink, The recording aptitude can be improved. As a result, the information sheet of the present invention can cope with various printing methods. The recording layer preferably contains 0.1 to 100% by mass of an antistatic agent, 0 to 99.9% by mass of a polymer binder, and 0 to 70% by mass of pigment particles, and the antistatic agent is 0.5 to 70% by mass. It is more preferable to contain 30 to 99.5% by mass of a polymer binder and 0 to 69.5% by mass of pigment particles, and 1 to 50% by mass of an antistatic agent and 50 to 99% by mass of a polymer binder More preferably, it contains 49% by mass.
The recording layer is provided by direct coating on the first resin layer as a coating layer containing these components, or the recording layer is formed in advance on another film and laminated on the first resin layer. It is preferable to form by carrying out.

  The antistatic agent is added to impart antistatic properties to the recording layer, and is exemplified by, for example, stearic acid monoglyceride, alkyl diethanolamine, sorbitan monolaurate, alkyl benzene sulfonate, alkyl diphenyl ether sulfonate and the like.

These antistatic agents have their respective characteristics, and low-molecular-weight organic compound-based antistatic agents are likely to be greatly affected by the environmental humidity, and their printing ink transferability and ink adhesion are degraded due to bleed out. There are drawbacks such as The conductive inorganic filler has a disadvantage that the antistatic effect can not be sufficiently obtained because the fillers do not contact with each other when added in a small amount. In addition, when the conductive inorganic filler is added in such an amount that the fillers come into contact with each other, the amount of the binder becomes extremely low, so that it is difficult to achieve both the adhesion of the ink and the antistatic effect. The electroconductive polymer generally has a black, green or blue-gray color due to the color derived from the conjugated system, and when it is used, an excellent antistatic effect can be obtained, but it becomes an oblong color label for printing There is a disadvantage that it is not suitable as a base paper.
The polymer having an antistatic function is preferable as the polymer having an antistatic function of the present invention because it has a small influence on the adhesion and transferability of the ink and almost no coloring.
Among them, quaternary ammonium salt type copolymers and alkali metal salt-containing polymers are more preferable because they have good antistatic performance and little influence of environmental humidity on antistatic performance.

(Copolymerization)
The alkali metal salt-containing polymer which can be used in the present invention has a polyalkylene oxide compound monomer structural unit (d) represented by the above general formula (Chem. 12) and a hydrophobicity represented by the above general formula (Chem. 6) It can be produced by copolymerizing a monomer structural unit (b) and a monomer structural unit (c) such as the above general formulas (7) to (11) copolymerizable with these. .
The method for producing the alkali metal salt-containing polymer is not particularly limited, and any known polymerization method can be suitably used alone or in combination, but like the quaternary ammonium salt type copolymer described above, a radical initiator It is preferable to adopt a known polymerization method such as bulk polymerization, solution polymerization, emulsion polymerization and the like.

  Among these, the more preferred polymerization method is solution polymerization. Specifically, a polyalkylene oxide compound monomer structural unit (d), a hydrophobic monomer structural unit (b), a copolymerizable monomer structural unit (c), etc., used as a raw material under nitrogen stream Monomers of an inert organic solvent such as n-hexane, n-butanol, 2-propanol, toluene, xylene, methyl ethyl ketone, acetone, methyl isobutyl ketone, cyclohexanone, ethyl acetate, isopropyl acetate, butyl acetate, tetrahydrofuran, ethyl cellosolve, It melt | dissolves in butyl cellosolve, a propylene glycol monoethyl ether etc., and after adding a radical polymerization initiator to this, it implements by stirring, heating at 65-150 degreeC normally.

The monomer solid content concentration during polymerization is usually 10 to 60% by weight, and the concentration of the polymerization initiator is usually 0.1 to 10% by weight with respect to the monomer. The molecular weight of the alkali metal salt-containing polymer can be any level depending on the polymerization conditions such as polymerization temperature, polymerization time, kind and amount of polymerization initiator, amount of solvent used, chain transfer agent and the like.

The molecular weight of the alkali metal salt-containing polymer which can be used in the present invention is gel permeation,
The weight average molecular weight measured by chromatography (GPC) is preferably in the range of 10,000 to 1,000,000. If the molecular weight is 10,000 or more, the polymer is less likely to exude from the formed coating layer, and thus sufficient water resistance tends to be easily obtained. If the molecular weight is 1,000,000 or less, there is a tendency that coating defects are less likely to occur and a uniform antistatic effect is likely to be obtained since the resin is easily mixed with the binder component.

The recording layer in the present invention may contain a polymer binder, if necessary. The polymer binder can be suitably used for the purpose of having adhesion to the first resin layer provided with the recording layer or another film and improving adhesion to the printing ink.
Specific examples of the polymer binder include polyethyleneimine, alkyl modified polyethyleneimine having 1 to 12 carbon atoms, poly (ethyleneimine-urea), ethyleneimine adduct of poly (ethyleneimine-urea), polyamine polyamide, polyamine polyamide Polyethyleneimine polymers such as ethyleneimine adducts and epichlorohydrin adducts of polyamine polyamides, acrylic acid ester copolymers, methacrylic acid ester copolymers, acrylic acid amide-acrylic acid ester copolymers, acrylic acid amide-acrylic acid Acrylic acid ester polymers such as ester-methacrylic acid ester copolymer, derivative of polyacrylamide, and oxazoline group-containing acrylic acid ester polymer, polyvinyl pyrrolidone, polyethylene glycol etc. , Vinyl acetate resin, urethane resin, polyether resin, polyester resin, urea resin, terpene resin, petroleum resin, ethylene-vinyl acetate copolymer, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, vinylidene chloride resin, Vinyl chloride-vinylidene chloride copolymer resin, chlorinated ethylene resin, chlorinated propylene resin, butyral resin, silicone resin, nitrocellulose resin, styrene-acrylic copolymer resin, styrene-butadiene copolymer resin, acrylonitrile-butadiene resin Copolymer etc. are mentioned.

  Any of these polymer binders may be used alone or in combination of two or more. These polymeric binders can be used in the form of being diluted or dispersed in an organic solvent or water. Among these, polyether urethanes, polyester polyurethanes, urethane resins such as acrylic urethanes, or acrylic acid ester copolymers have good compatibility (compatibility) with the above-mentioned ionic polymer-based polymers having an antistatic function, It is stable when mixed and dissolved to make a coating, and it is easy to coat and preferable.

The recording layer in the present invention may contain pigment particles as required. The recording layer can contain pigment particles in the range of 0 to 70% by mass. That is, 70 mass% or less of pigment particles may or may not be contained.
The pigment particles improve the fixability of the printing ink by oil absorption, improve the texture and gloss of the surface as an extender pigment, improve the whiteness as a white pigment, improve the blocking prevention performance by imparting surface irregularities, and improve the light resistance and weather resistance as an ultraviolet reflector. It can be appropriately selected and used in consideration of performance addition such as property improvement.

  Organic and inorganic fine powders are used as pigment particles, and specific examples thereof include silicon oxide, calcium carbonate, calcined clay, titanium oxide, zinc oxide, barium sulfate, diatomaceous earth, acrylic particles, styrene particles, polyethylene particles, Polypropylene particles and the like can be used. The particle size of the pigment particles is preferably 20 μm or less, more preferably 15 μm or less. When the particle diameter of the pigment particles exceeds 20 μm, the pigment particles are easily detached from the formed coating layer, and the powder blowing phenomenon occurs. The pigment particle content in the recording layer is preferably in the range of 0 to 70% by weight, more preferably 0 to 60% by weight, and still more preferably 0 to 45% by weight. When the content of the pigment particles exceeds 70% by weight, the binder resin is relatively insufficient, and the cohesion of the recording layer is insufficient, and the printing ink tends to be easily peeled off.

The recording layer can be provided as a coating layer by preparing a coating liquid containing the above-mentioned components, coating it on an opaque film layer or the like, drying it and solidifying it. For coating, conventionally known methods and apparatuses can be used.
The recording layer can also be provided on the opaque film layer by lamination. In this case, another film provided with a recording layer may be prepared in advance and laminated to an opaque film layer. Lamination can be performed by methods such as ordinary dry lamination or melt lamination.
It is preferable to set the recording layer on the opaque film layer before carrying out the charging process described later. The antistatic performance of the recording layer makes it possible to suppress the electrostatic adsorption force on the recording layer side even after the charging process.

The recording layer of the present invention has antistatic properties. The surface resistivity of the recording layer surface is in the range of 1 × 10 ^{−1 to} 9 × 10 ¹² Ω, preferably 1 × 10 ^{3 to} 9 × 10 ¹¹ Ω, and more preferably 1 × 10 ^{6 to} 9 × 10 ¹⁰ Ω. It has been adjusted.
When the surface resistivity of the recording layer exceeds 9 × 10 ¹² Ω, the electrostatic adsorption force of the opaque film layer can not be sufficiently suppressed, and the information sheet adheres to the roll in the printing step or between the sheets. Problems such as blocking may easily occur. On the other hand, when the surface resistivity of the recording layer is less than 1 × 10 ^-1 Ω, the electrostatic adsorption power of the opaque film layer may be impaired, and a recording layer having such high conductivity is formed. Things are technically difficult, or even if they can be formed, they are not realistic because they become expensive.

  The film thickness of the recording layer is preferably 0.01 to 50 μm, more preferably 0.05 to 30 μm, still more preferably 0.1 to 10 μm, and 0.3 to 8 μm. Is particularly preferred. If the film thickness is less than 0.01 μm, it is difficult to maintain the uniformity of the recording layer, and the adhesion of the printing ink may be reduced. On the other hand, if it exceeds 50 μm, the recording layer becomes heavy, and the adsorption power of the opaque film layer due to static electricity can not support its own weight, it becomes easy to be peeled off, and it is difficult to achieve the desired performance of the present invention.

[Transparent film layer]
(First transparent film layer)
The first transparent film layer constituting the information sheet of the present invention contains a second resin layer and is adsorbed or adhered to the side of the opaque film layer opposite to the one side having the information. In the first transparent film layer, for example, the opaque film layer is subjected to charging treatment described later, and brought into contact with the first resin layer of the opaque film layer in which the electric charge is accumulated therein, and laminated by electrostatic adsorption. Alternatively, a pressure-sensitive adhesive layer or an adsorption layer to be described later is provided on the opaque film layer, and the pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer or the adsorption surface of the adsorption layer is adhered to or adsorbed on the first resin layer. In the present invention, a transparent film layer means a layer having an opacity of less than 50%. When the transparency of the transparent film layer exceeds 50%, when the information sheet of the present invention is used as an information display, it becomes difficult to observe information through the transparent film layer.
In addition, in the case where the first transparent film layer constituting the information sheet of the present invention contains a resin film similar to the above-mentioned opaque film layer, the first transparent film layer is subjected to a charging treatment to accumulate charges therein. After forming a transparent film layer, it can be brought into contact with the first resin layer of the opaque film layer and laminated by electrostatic adsorption to form the information sheet of the present invention.
Like the opaque film layer, the first transparent film layer can be configured such that the information sheet combined with the opaque film layer has antistatic performance on both sides by having antistatic performance on one side . As a result, particularly when electrostatic attraction is used to adsorb the opaque film layer and the first transparent film layer, the information sheet, which is a laminate, does not express electrostatic attraction to the outside, and transports the information sheet, It is difficult to cause troubles such as sticking to the surroundings or blocking between information sheets at the time of handling such as storage, printing, etc., and the handling property becomes good.

The first transparent film layer is suitably selected from materials known in the art in consideration of adsorption or adhesion with the opaque film layer, and provision of antistatic performance.
The first transparent film layer may have a single layer structure or a multilayer structure of two or more layers. In particular, when electrostatic adsorption is used to adsorb the opaque film layer and the first transparent film layer, as described above, the first transparent film layer can be electrostatically adsorbed with one side thereof in contact with the opaque film layer. It is preferable to have a multi-layered structure because the opposite surface is configured to have antistatic performance.

Moreover, when using an electrostatic adsorption force for adsorption | suction with an opaque film layer and a 1st transparent film layer, it is preferable that a 1st transparent film layer has the following characteristics.
First, it is preferable that the first transparent film layer has a relative dielectric constant in the range of 1.1 to 5.0 by being formed of these materials, or by processing such as forming an air gap inside. When laminating an opaque film layer and a first transparent film layer, the relative dielectric constant of the first transparent film layer is preferably 1.1 to 5.0, and 1.2 to 4.0. It is more preferable that the ratio be 1.5 to 3.0. When the relative dielectric constant of the first transparent film layer is 5.0 or less, the opaque film layer can hold the charge for a long time, and the electrostatic adsorption force is unlikely to be reduced. On the other hand, the relative dielectric constant is preferably 1.1 or more from the technical viewpoint.

Furthermore, the first transparent film layer is made of a resin excellent in insulation from the viewpoint of reducing charge transfer, and the surface resistivity of the first transparent film layer in contact with the opaque film layer is 1 × 10 ^13. It is preferable to be in the range of -9 × 10 ¹⁷ Ω. The surface resistivity is more preferably in the range of 5 × 10 ^{13 to} 9 × 10 ¹⁶ Ω, and still more preferably in the range of 1 × 10 ^{14 to} 9 × 10 ¹⁵ Ω. When the surface resistivity is 1 × 10 ¹³ Ω or more, the charge of the opaque film layer is unlikely to escape to the outside (in the air, etc.) along the same surface, and the opaque film layer can hold the charge for a long time, It becomes difficult to decrease. On the other hand, the surface resistivity is preferably 9 × 10 ¹⁷ Ω or less from the viewpoint of cost and technology.

On the other hand, the first transparent film layer can be provided with antistatic performance on the surface coming to the outer layer of the information sheet, for the purpose of providing antistatic performance on one side thereof.
The addition of the antistatic property to the first transparent film layer can be achieved by a method of providing the same as the recording layer (B) used for the opaque film layer, a method of applying a conductive paint and providing a conductive layer, The method of providing a metal thin film by direct vapor deposition, transfer vapor deposition, lamination of a vapor deposition film etc., the method of kneading an antistatic agent to resin which comprises a 1st transparent film layer, etc. are mentioned.

According to the above method, the surface resistivity of the surface of the first transparent film layer which comes to the outer layer of the information sheet is preferably in the range of 1 × 10 ^{−1 to} 9 × 10 ¹² Ω. The surface resistivity is preferably in the range of 1 × 100 to 9 × 10 ¹¹ Ω.
When the surface resistivity of the surface of the first transparent film layer coming to the outer layer of the information sheet is 9 × 10 ¹² Ω or less, the antistatic performance is sufficient, and adhesion to the periphery of the information sheet, information sheets It is hard for troubles such as blocking to occur. On the other hand, the surface resistivity is preferably 1 × 10 ⁻¹ Ω or more from the technical viewpoint.

Further, when the thickness is 500 μm or less, the thickness of the obtained information sheet can be reduced, and the workability in the printing process and the cutting process can be improved.

(Second and third transparent film layers)
The second transparent film layer constituting the information sheet of the present invention includes the third resin layer and is adsorbed or adhered to the second resin film layer to constitute a sticking sheet. As the second transparent film layer, those made of known materials are appropriately selected in consideration of adsorption or adhesion with the second resin film, and provision of antistatic performance in the case of using electrostatic adsorption. The second resin film may be a third transparent film layer. For the second and third transparent film layers, the same material as the first transparent film layer can be used, and the adhesive sheet containing the second transparent film layer is produced by the same method as the information sheet, for example, JP-A It can manufacture by the method as described in the 2012-145935 gazette.

[Charging process]
In the information sheet of the present invention, the opaque film layer is subjected to charging treatment, and then the laminate obtained by electrostatically adsorbed in contact with the first transparent film layer or the first transparent film layer is subjected to charging treatment, and then opaque. It includes a laminate which is electrostatically adsorbed in contact with a film layer.
The method of the charging treatment is not particularly limited, and can be performed according to various known methods. For example, after an opaque film layer is formed, corona discharge or pulsed high voltage is applied to the surface of the opaque film layer, or both surfaces of the opaque film layer are held with a dielectric and a direct current high voltage is applied to both sides (electro Electretization method, a method (radio electretization method) of irradiating the opaque film layer with ionizing radiation such as γ-ray and electron beam, and the like (radio electretization method) may be mentioned.
As a more specific example of the electro-electretization method, a method of fixing an opaque film layer or a first transparent film layer between an application electrode connected to a DC high voltage power supply and a ground electrode (batch method, see FIGS. 12 and 13) Or a method of passing (continuous, see FIGS. 14 and 15) is desirable. In the case of using this method, it is desirable to arrange needles in an infinite number at equal intervals or to use metal wires, and to use a flat metal plate or a metal roll as a counter electrode.
In the present invention, the charging treatment is preferably a direct current type corona discharge treatment. The DC corona discharge treatment that can be used in the present invention includes a needle or wire main electrode (application electrode) and a flat or roll counter electrode (earth electrode) as shown in FIGS. An opaque film layer is formed by corona discharge generated by placing an opaque film layer or a first transparent film layer on the counter electrode using a device connected to a power supply, and applying a high DC voltage between the main electrode and the counter electrode. Or it is the process which injects an electric charge into a 1st transparent film layer.

The distance between the main electrode and the counter electrode is preferably 1 to 50 mm, more preferably 2 to 30 mm, and still more preferably 5 to 20 mm. If the distance between the electrodes is less than 1 mm, it is difficult to keep the distance between the electrodes uniform, and uniform charging may not be obtained in the width direction. On the other hand, if it exceeds 50 mm, corona discharge is less likely to occur, and in some cases, the charging process to the opaque film layer or the first transparent film layer may be uneven.
The voltage applied between both electrodes is determined by the electrical properties of the opaque film layer and the first transparent film layer, the shape and material of the main electrode and the counter electrode, and the distance between the main electrode and the counter electrode. 1 to 100 KV is preferable, 3 to 70 KV is more preferable, 5 to 50 KV is more preferable, and 10 to 30 KV is particularly preferable. The polarity of the main electrode may be positive or negative. However, it is preferable to use a negative polarity on the main electrode side because a relatively stable corona discharge state is obtained.
The material of the main electrode and the counter electrode is appropriately selected from conductive materials, but metals such as iron, stainless steel, copper, brass, tungsten and the like or carbon are preferable.
The amount of charge introduced into the opaque film layer or the first transparent film layer by these charging treatments depends on the amount of current flowing between the main electrode and the counter electrode during the treatment. Since the amount of current increases as the voltage between both electrodes increases, the applied voltage is preferably set high enough to prevent dielectric breakdown of the opaque film layer or the first transparent film layer.

It is preferable to carry out the charging process to the opaque film layer by a method of applying the above-mentioned corona discharge or high voltage to the surface on which the recording layer is not provided. It is preferable that the recording layer has an antistatic performance, and such surface electrification is not effective because there is a high possibility that the applied charge may be dissipated to the periphery through the recording layer. Such a problem does not particularly occur when the recording layer is in contact with the ground side (metal plate or metal roll).
The information sheet, the opaque film layer or the first transparent film layer of the present invention can also be subjected to charge removal treatment after charge treatment. By performing the static elimination process, it is possible to avoid problems in the printing process, the processing process for the label and the like. A known method such as a voltage application type static elimination (ionizer) or a self-discharge type static elimination can be used for the static elimination processing. These general static eliminators can remove the charge on the surface, but can not remove the charge accumulated inside the resin layer. Therefore, the electrostatic adsorption power of the opaque film layer or the first transparent film layer is not greatly affected by the static elimination treatment.

[Stacking]
The information sheet of the present invention comprises a laminate in which the opaque film layer constituting the same is brought into contact with the first transparent film layer, or these two layers are laminated via an adsorption layer or an adhesive layer.

To perform charging processing, and separately wind the second resin layer (first transparent film layer) as a long roll-up (42), and press-bond the both with a pressure roll (49) Can be done by
Also, for example, the lamination of an opaque film layer provided with a first adsorptive layer or a first adhesive layer and a first transparent film layer is a manufacturing apparatus excluding the electrodes 45 and 46 in FIG. The two layers can be formed by pressure-adhering the layers at the points of the rolls (48) and (49), with the adsorption layer or the adhesive layer interposed between the two layers.
