Description

  The present invention relates to an information sheet that can be adsorbed or adhered to various adherends. The present invention also relates to an information display body in which an information sheet is adsorbed or adhered to an adherend.

  Conventionally, adhesives, pressure-sensitive adhesive tapes, etc. have been used to attach printed media such as posters and advertisements to hard substrates such as walls, glass surfaces, pillars, bulletin boards, lockers and bookcases. I came. In recent years, it has been desired that such a sheet-like medium such as an advertisement can be easily collected in a reusable state after use from the viewpoint of material recycling. However, when an adhesive or a double-sided tape is used, it is not easy to peel off advertisements and the like from the adherend, and it may be torn and cannot be reused. In addition, if adhesives or adhesives remain in advertisements, recycling as resources becomes difficult, and eventually there is a problem that most of them are treated as waste after being used once. Furthermore, if a sheet-like medium such as an advertisement is attached to an adherend such as a wall surface or a pillar using an adhesive or a double-sided tape, glue or the like may remain on the adherend side after peeling it, There was also a problem that the surface of the adherend peeled off.

  On the other hand, the technique which affixes sheet-like media, such as an advertisement, to a to-be-adhered body by an electrostatic attraction force is proposed (refer the following patent document 1). 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 peeled surface is exposed. It is described that a label layer is attached so as to be in contact with the adherend surface and electrostatically adsorbed. According to Patent Document 1, since the sheet before peeling does not develop an electrostatic adsorption force to the outside before peeling, there is an advantage that troubles such as sticking to a roll and blocking between sheets are unlikely to occur particularly in a printing process. In addition, it has good handling properties and can be used for various printing methods. Further, according to Patent Document 1, after being attached to an adherend, there is an advantage that the electrostatic attraction force lasts for a long time without being influenced by the environmental humidity, and can be easily peeled off after use. It is said that.

  However, the sheet of Patent Document 1 has a problem in that the support layer remains at hand after the label layer is peeled off from the sheet to be attached to the adherend. For this reason, it took time and effort to recover, transport and process the support layer after attaching the label layer to the adherend. Therefore, it has been desired to avoid a situation in which a large amount of wasted material comes out.

  On the other hand, it is required to print various kinds of information on the label layer, but in the case of information including maps, printing with various information according to individual purposes while using a common map as a base. Is often required. For example, printing that indicates the location of a store, etc., or printing that indicates the route to the destination, etc., may be printed on a common map and overlaid, or the common map may be modified from the original and printed. ing. However, in order to respond to a wide variety of needs, it is inefficient and time-consuming to print a map to which information that matches each need is added each time. For this reason, it is convenient to have a sheet that can easily add individual information corresponding to each need to the map while using the map itself in common. However, such a convenient sheet has not been developed yet.

  Further, a map displayed as a display body is often touched by a passerby or the like with a finger. For this reason, printing at specific points such as important points and destinations frequently becomes thinner or peeled off than others. Therefore, it was also necessary to properly protect the displayed map.

  The present inventors have intensively studied in order to solve the above-described problems of the prior art. As a result, a sheet was prepared by adsorbing or adhering the transparent film layer and the opaque film layer on which information was printed, and the transparent film remaining after the opaque film layer was peeled off and adhered to the adherend during use. We found that the problem can be solved by pasting the layer on the 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 pasted on the information, and information according to individual needs can be displayed. Further, additional information can be given to the transparent film layer with a marker or the like.

(Information display)
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 a laminated structure of the information display body of the present invention. In FIG. 7, members that are the same as those in FIG. 1 and FIG. As shown in FIG. 7, the information display body has a structure in which a laminate 10 including a resin film layer 2 ′ and a first transparent film layer 3 is electrostatically adsorbed on an adherend 5. The resin film layer 2 ′ includes the first resin layer, and information 4 is given to one surface (surface 2B) of the resin film layer 2 ′. And the 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. For this reason, the 1st resin layer which comprises resin film layer 2 'may be the same as the 1st resin layer which comprises an opaque film layer.

  For this reason, the information display body of FIG. 7 covers the peeling surface 2A of the opaque film layer 2 charged by static electricity after peeling off the first transparent film layer 3 from the opaque film layer 2 as described above, for example. It can be produced by adsorbing to the adherend 5 and further adsorbing the peel surface 3A of the first transparent film layer 3 charged by static electricity on 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. Further, since the laminate 10 is adsorbed to the adherend 5 by static electricity, the paste remains on the adherend 5 side when it is removed from the adherend 5 and collected after serving as an information display body. It can be easily peeled off without peeling off or peeling off the surface coating. Moreover, 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 the adhesion of dust and the like due to static electricity.

It has a structure that adheres onto the body 5. The resin film layer 12 ′ includes the first resin layer, and information 4 is given to one surface (surface 12B) of the resin film layer 12 ′. And one surface 16A (or 16B) of the first transparent film layer 16 is adhered via the second adhesive layer 15 on the surface (surface 12B) having the information 4 of the resin film layer 12 ′. . 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. For this reason, the 1st resin layer which comprises resin film layer 12 'may be the same as the 1st resin layer which comprises an opaque film layer.

Such an information display body can be manufactured by using, for example, the information sheets (adhesive information sheets) 11 and 17 of the present invention shown in FIGS.
In order to manufacture the information display body, first, the laminate composed of the release layer 14, the second adhesive layer 15, and the first transparent film layer 16 is peeled from the first adhesive layer 13 of the adhesive information sheets 11 and 17. Thus, after separating the opaque film layer 12 and the first transparent film layer 16, the peel surface 13 </ b> A of the first adhesive layer 13 provided on the opaque film layer 12 is adhered to the adherend 5. Further, the release layer 14 is peeled off from the second adhesive layer 15 provided on the first transparent film layer 16, and the release surface 15 A of the second adhesive layer 15 is adhered onto the information 4 of the opaque film layer 12. Can be produced.

Further, when the adhesive information sheet 17 shown in FIG. 5 was used as the information sheet, the adhesive information sheet 17 was on the opaque film layer 12 side among the surfaces 16A and 16B of the first transparent film layer 16. The surface 16A forms an outer surface of the information display body (a surface opposite to the surface on the resin film layer 12 ′ side).

Such an information display body includes a first adsorbing layer instead of the first adhesive layer 13 in the adhesive information sheet shown in FIG. 3 or 5, and a second adsorbing layer instead of the second adhesive layer 15. Can be manufactured by the same process as the case of using the adhesive information sheet shown in FIG. 3 or FIG. In such an information display body, since the laminate is adsorbed to the adherend by negative pressure, the paste remains on the adherend side when it is removed from the adherend and collected after serving as the information display body. It can be easily peeled off without peeling off or peeling off the surface coating.

In addition, when the first additional information is variable information at the time of use, information that can be changed using a method such as a marker, a label, or a sticky note is attached so that a group of information is displayed when the information is superimposed. It is preferable.

The resin film layer and the adherend in the information display body of the present invention may each be made of a transparent material. By doing so, it becomes possible to visually recognize the information 4 and the first additional information 7 together with the background behind the information display body. Further, the information display body information 4 and the first additional information 7 can be viewed not only from the laminate 10 side but also from the adherend 5 side. For example, if a window made of transparent glass or transparent resin is selected as the adherend and the laminated body 10 is formed inside the window, the information 4 and the first additional information 7 are visually recognized from both the inside and outside of the window. can do. When the information display body is intended to be viewed from the adherend 5 side, the information 4 is displayed on the front surface of the first additional information 7, so that information can be obtained by adjusting the first additional information 7. It becomes easy to change the background.

[Opaque film layer]
The opaque film layer constituting the information sheet of the present invention includes the first resin layer and has information on one surface. In the present invention, the opaque film layer means a layer having an opacity of 50 to 100%.

The opacity of the opaque film layer is preferably 60 to 100%, more preferably 70 to 100%. The opacity in the present invention is displayed in accordance with JIS-P-8138, with a black and white standard plate applied to the measurement back surface, and the light reflectance ratio (black plate / white plate) expressed as a percentage. The
In addition, the resin film layer of the information display body of this invention can also be set as the structure similar to the opaque film layer in the information sheet of this invention.

When the thickness of the opaque film layer is 20 μm or more, wrinkles are not easily formed when the opaque film layer is applied to the adherend, and it is easy to apply it well. Also, if the thickness of the opaque film layer is 500 μm or less, the weight of the opaque film layer does not become too large, and the weight of the opaque film layer falls from the adherend without being able to hold its own weight due to electrostatic adsorption force, other adsorption force, or adhesive force. Can be prevented.

[First resin layer]
The first resin layer in the present invention constitutes an opaque film layer. When the opaque film layer is affixed to the adherend by electrostatic attraction force, the first resin layer retains electric charge therein by further charging, and the opaque film layer by the electrostatic attraction force. The layer can be attached to the adherend as a display object.
It is preferable that the 1st resin layer of this invention contains a thermoplastic resin. In particular, it is preferable to use a thermoplastic resin having an excellent insulating property as the first resin layer of the opaque film layer to be attached by electrostatic attraction, so that the charges accumulated therein can be easily retained.

One or two or more of these functional group-containing monomers may be appropriately selected and copolymerized as necessary.
Furthermore, these polyolefin resins and functional group-containing polyolefin resins can be used after being graft-modified if necessary.

  A known technique can be used for graft modification, and specific examples include graft modification with an unsaturated carboxylic acid or a derivative thereof. Examples of the unsaturated carboxylic acid include acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid and the like. As the unsaturated carboxylic acid derivative, acid anhydrides, esters, amides, imides, metal salts and the like can also be used.

  Among these thermoplastic resins, it is preferable to use a polyolefin resin and a functional group-containing polyolefin resin excellent in insulation and processability. As the thermoplastic resin of the first resin layer, one type may be selected from the thermoplastic resins described above and used alone, or two or more types may be selected and used in combination. Furthermore, among these polyolefin resins, propylene resins are preferable from the viewpoints of insulation, processability, chemical resistance, cost, and the like. The propylene-based resin is a propylene homopolymer mainly composed of polypropylene or propylene having isotactic or syndiotactic and various degrees of stereoregularity, propylene, ethylene, 1-butene, 1- It is desirable to use a copolymer obtained by copolymerizing an α-olefin such as hexene, 1-heptene, 4-methyl-1-pentene as a main component. This copolymer may be a binary system or a ternary system or may be a random copolymer or a block copolymer. The propylene-based resin is preferably used by blending 2 to 25% by mass of a resin having a melting point lower than that of the propylene homopolymer. Examples of such a resin having a low melting point include high-density or low-density polyethylene.

  The thermoplastic resin used for the first resin layer in the present invention may be one to which at least one of inorganic fine powder and organic filler exemplified below is added. By adding an inorganic fine powder or an organic filler and a stretching process described later, it becomes easy to form pores in the first resin layer. The total amount of the thermoplastic resin in the first resin layer is preferably 50 to 100% by mass, and more preferably 60 to 100% by mass. When the blending amount is 50% by mass or more, the first resin layer can be easily molded, and the thermoplastic resin in the obtained first resin layer can be easily retained.

  When adding an inorganic fine powder, the average particle diameter measured with the particle size distribution meter by laser diffraction is 0.01-15 micrometers normally, Preferably 0.1-5 micrometers is used. Specifically, calcium carbonate, calcined clay, silica, diatomaceous earth, white 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 different type of resin from the thermoplastic resin that is the main component of the first resin layer. For example, when the thermoplastic resin is a polyolefin resin, the organic filler is a polymer such as polyethylene terephthalate, polybutylene terephthalate, polycarbonate, nylon-6, nylon-6,6, cyclic polyolefin, polystyrene, polymethacrylate, etc. In addition, an incompatible material having a melting point (for example, 170 to 300 ° C.) or a glass transition temperature (for example, 170 to 280 ° C.) higher than the melting point of the polyolefin resin can be used.

  A heat stabilizer (antioxidant), a light stabilizer, a dispersant, a lubricant and the like can be added to the first resin layer as necessary. When adding a heat stabilizer, it is usually added within a range of 0.001 to 1% by mass. Specifically, sterically hindered phenol-based, phosphorus-based, amine-based stabilizers, and the like can be used. When using a light stabilizer, it is normally used within the range of 0.001 to 1% by mass. Specifically, sterically hindered amine-based, benzotriazole-based, benzophenone-based light stabilizers, and the like can be used. A dispersant or a lubricant is used for the purpose of dispersing inorganic fine powder, for example. 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 acid, polymethacrylic acid 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 workability can be improved. In addition, it is less likely to wrinkle when applied to an adherend and has excellent appearance. In addition, when the thickness is 500 μm or less, the first resin layer does not become too heavy, and it is possible to prevent the first resin layer from falling off the adherend without being able to hold its own weight by the electrostatic adsorption force.

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

[Stretching]
The first resin layer preferably includes a stretched resin film layer stretched in at least one axial direction. The stretching of the resin film layer can be performed by any of various methods that are usually used.
The stretching temperature can be carried out within a known temperature range suitable for a thermoplastic resin having a temperature not lower than the glass transition temperature of the thermoplastic resin mainly used for the first resin layer 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 thermoplastic resin is high density polyethylene (melting point 121 to 136 ° C.), it is 70 to 135. It is a temperature 1 to 70 ° C. lower than the melting point. The stretching speed is preferably 20 to 350 m / min.

As stretching methods, longitudinal stretching using the difference in peripheral speed of the roll group, transverse stretching using a tenter oven, sequential biaxial stretching combining longitudinal stretching and transverse stretching, rolling, simultaneous combination of a tenter oven and a linear motor 2 Examples thereof include axial stretching and simultaneous biaxial stretching by a combination of a tenter oven and a pantograph. In addition, as a method for stretching an inflation film, simultaneous biaxial stretching by a tubular method can be exemplified.
The draw ratio is not particularly limited, and is appropriately determined in consideration of the characteristics of the thermoplastic resin used for the first resin layer. For example, when a propylene homopolymer or a copolymer thereof is used as a thermoplastic resin and is stretched in one direction, it is about 1.2 to 12 times, preferably 2 to 10 times. The area magnification is 1.5 to 60 times, preferably 4 to 50 times. When other thermoplastic resins are used and stretched in one direction, they are 1.2 to 10 times, preferably 2 to 5 times. In the case of biaxial stretching, the area magnification is 1.5 to 20 times, preferably 4 to 12 times.

The first resin layer thus obtained has a large number of fine pores inside the film, and the porosity calculated by the following formula (1) is preferably 5 to 60%, More preferably, it is 10 to 45%. Due to the presence of the pores, the number of interfaces in the resin film increases, and it becomes easier to hold charges inside. When this is compared with a resin film having no pores, the performance of accumulating charges inside is improved, so that the adsorption performance is hardly lowered even in a high humidity environment. In addition, the first resin layer with high opacity can be obtained by the effect of improving the light diffusivity by the holes.

The surface resistivity of the surface of the first resin layer on which information is not provided 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 escapes through the surface during the charging process described later, so that the efficiency of charge injection into the first resin layer is reduced and the charging process is excessive. Energy is required, or the effect of the charging process cannot be obtained and the electrostatic adsorption performance is low. 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 due to high cost. The surface resistivity of the surface of the first resin layer on which the recording layer is not provided is in a desired range by using a polyolefin-based resin having excellent insulating properties as the thermoplastic resin, or by using the inorganic fine powder blended therein. This can be achieved by adjusting the type and amount.

[Recording layer]
The opaque film layer constituting the information sheet of the present invention can be provided with a recording layer on one side of the above-mentioned opaque film layer. The recording layer improves the handling properties by imparting antistatic performance to the opaque film layer, making it difficult to cause troubles in the printing process, and improving the adhesion with the printing ink of the opaque film layer, The recordability can be improved. As a result, the information sheet of the present invention can correspond to 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 0.5 to 70% by mass of the antistatic agent. More preferably 30 to 99.5% by mass of polymer binder and 0 to 69.5% by mass of pigment particles, 1 to 50% by mass of antistatic agent, 50 to 99% by mass of polymer binder, and 0 to 0% of pigment particles. More preferably, it contains 49% by mass.
The recording layer is provided as a coating layer containing these components by direct coating on the first resin layer, or a recording layer is previously formed on another film and laminated on the first resin layer. It is preferable to form by doing.

  The antistatic agent is added to impart antistatic performance to the recording layer, and is represented by, for example, stearic acid monoglyceride, alkyldiethanolamine, sorbitan monolaurate, alkylbenzene sulfonate, alkyl diphenyl ether sulfonate, and the like.

Id, quaternary ammonium salt type copolymers such as polydimethylaminoethyl methacrylate quaternized compounds, and charge represented by alkali metal salt-containing polymers such as alkali metal ion additives to alkylene oxide group and / or hydroxyl group-containing polymers Examples thereof include a polymer having a prevention function.

Each of these antistatic agents has its characteristics, and low molecular weight organic compound-based antistatic agents are highly susceptible to the antistatic performance due to environmental humidity, resulting in a decrease in printing ink transferability and ink adhesion due to bleeding out. There are disadvantages such as. When the conductive inorganic filler is added in a small amount, the fillers do not come into contact with each other, and thus there is a drawback that the antistatic effect cannot be sufficiently obtained. 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 is remarkably reduced, so that it is difficult to achieve both the ink adhesion and the antistatic effect. Electronically conductive polymers generally have black, green, or blue-gray coloration due to the color derived from the conjugated system, and if this is used, an excellent antistatic effect can be obtained, but it becomes a dull color label for printing. There are disadvantages such as being unsuitable as a base paper.
A polymer having an antistatic function is preferable as the polymer having the antistatic function of the present invention because it has little influence on the adhesion and transferability of the ink and is hardly colored.
Among them, quaternary ammonium salt type copolymers and alkali metal salt-containing polymers are more preferable because they have good antistatic performance and have little influence on the antistatic performance of environmental humidity.

Examples of the substituent include a hydroxyl group and an alkyl group. Examples of the arylene group substituted with an alkyl group include a tolylene group and a xylylene group.
Moreover, as a coupling group selected from <Group 2>, a urethane group and an ester group can be preferably selected.

  As the linking group in which one or more linking groups selected from <Group 1> and one or more linking groups selected from <Group 2> are alternately bonded, “(the linking group selected from Group 1” is used. )-(Linking group selected from group 2) "or" (linking group selected from group 1)-(linking group selected from group 2)-(selected from group 1) Linking group)-(linking group selected from Group 2) "and the like.

Although n represents the integer of 1-100, 2-50 are preferable and 3-50 are more preferable.

In the above general formula (Formula 12), M is an alkali metal, and examples thereof include Li, Na, and K. It is preferable to use Li having a small ionic radius from the viewpoint of conductivity.

It is desirable to add a polymer having an antistatic function so that a sufficient antistatic effect cannot be obtained when the alkali metal ion concentration is less than 0.01% by weight. Although the effect is obtained, the adhesion with the printing ink is lowered due to the increase of metal ions.

(Copolymerization)
The alkali metal salt-containing polymer that can be used in the present invention includes a polyalkylene oxide compound monomer structural unit (d) represented by the general formula (Formula 12) and a hydrophobic property represented by the general formula (Formula 6). It can be produced by copolymerizing the monomer structural unit (b) and the monomer structural unit (c) such as the above general formulas (Chemical Formula 7) to (Chemical Formula 11) copolymerizable therewith. .
The method for producing the alkali metal salt-containing polymer is not particularly limited, and can be appropriately used alone or in combination with known polymerization techniques. However, like the quaternary ammonium salt copolymer, the radical initiator is used. It is preferable to employ a known polymerization method such as bulk polymerization, solution polymerization or emulsion polymerization using

  Among these, a more preferable polymerization method is a solution polymerization method. Specifically, in a nitrogen stream, a polyalkylene oxide compound monomer structural unit (d) used as a raw material, a hydrophobic monomer structural unit (b), a copolymerizable monomer structural unit (c), etc. 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, After dissolving in butyl cellosolve, propylene glycol monoethyl ether, etc. and adding a radical polymerization initiator to this, it is usually carried out by stirring while heating at 65 to 150 ° C. The polymerization time is usually set to 1 to 24 hours. The monomer solid 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 set at an arbitrary level depending on the polymerization conditions such as the polymerization temperature, the polymerization time, the type and amount of the polymerization initiator, the amount of solvent used, and the chain transfer agent.

  The polymerization initiator used for copolymerization is preferably fat-soluble, and examples of suitable polymerization initiators include organic peroxides and azonitriles. Organic peroxides include alkyl peroxides (dialkyl peroxides), aryl peroxides (diaryl peroxides), acyl peroxides (diacyl peroxides), aroyl peroxides (diaroyl peroxides), ketone peroxides, peroxides Carbonates (peroxydicarbonates), peroxycarbonates, peroxycarboxylates, hydroperoxides, peroxyketals, peroxyesters and the like are included.

The molecular weight of the alkali metal salt-containing polymer that 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 difficult to ooze out from the formed coating layer, so that sufficient water resistance tends to be obtained. If the molecular weight is 1,000,000 or less, it tends to be miscible with the binder component, so that coating defects are less likely to occur and a uniform antistatic effect tends to be obtained.

The recording layer in the invention may contain a polymer binder as necessary. The polymer binder can be appropriately used for the purpose of improving the adhesion to the printing resin and the first resin layer on which the recording layer is provided or to another film.
Specific examples of the polymer binder include polyethyleneimine, alkyl-modified polyethyleneimine having 1 to 12 carbon atoms, poly (ethyleneimine-urea), an ethyleneimine adduct of poly (ethyleneimine-urea), polyamine polyamide, and polyamine polyamide. Polyethyleneimine-based polymers such as ethyleneimine adducts and epichlorohydrin adducts of polyamine polyamide, acrylic ester copolymers, methacrylic ester copolymers, acrylic amide-acrylic ester copolymers, acrylic amide-acrylic acids Addition of ester-methacrylic acid ester copolymer, polyacrylamide derivative, acrylic acid ester polymer such as oxazoline group-containing acrylic acid ester polymer, polyvinylpyrrolidone, 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 A copolymer etc. are mentioned.

  Any one of these polymer binders may be used alone, or two or more thereof may be mixed and used. These polymer binders can be used in the form diluted or dispersed in an organic solvent or water. Among these, urethane resins such as polyether urethane, polyester polyurethane, and acrylic urethane, or acrylic acid ester copolymers have good compatibility (compatibility) with the above-described ionic polymer-based polymer having an antistatic function, It is stable when mixed and used as a paint, and is easy to apply and preferable.

The recording layer in the invention may contain pigment particles as necessary. The recording layer can contain pigment particles in the range of 0 to 70% by mass. That is, it may or may not contain 70% by mass or less of pigment particles.
Pigment particles improve the fixability of printing inks due to their oil absorption, improve the texture and gloss of the surface as extender pigments, improve the whiteness as white pigments, improve the anti-blocking performance by imparting surface irregularities, and light and weather resistance as UV reflectors In view of imparting performance such as improvement in performance, it can be appropriately selected and used.

  As pigment particles, organic and inorganic fine powders are used. Specific examples 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 diameter 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 easily fall off from the formed coating layer, and a 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 pigment particle content exceeds 70% by weight, the binder resin is relatively insufficient, the cohesive force of the recording layer is insufficient, and the printing ink tends to be peeled off.

The recording layer can be provided as a coating layer by preparing a coating solution containing the above components, coating it on an opaque film layer or the like, and drying and solidifying the coating layer. For coating, a conventionally known method or apparatus 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 in advance may be prepared and laminated on the opaque film layer. Lamination can be performed by a technique such as ordinary dry lamination or melt lamination.
The recording layer is preferably placed on the opaque film layer before the below-described charging process is performed. The antistatic performance of the recording layer makes it possible to suppress the electrostatic adsorption force on the recording layer surface side even after the charging process.

The recording layer of the present invention has antistatic performance. 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, more preferably 1 × 10 ^{6 to} 9 × 10 ¹⁰ Ω. It has been adjusted.
If the surface resistivity of the recording layer exceeds 9 × 10 ¹² Ω, the electrostatic adsorption force of the opaque film layer cannot be sufficiently suppressed, and the information sheet is stuck to a roll or between sheets in the printing process. There are cases where troubles such as blocking are likely to occur. On the other hand, when the surface resistivity of the recording layer is less than 1 × 10 ⁻¹ Ω, the electrostatic adsorption force of the opaque film layer may be impaired, and a recording layer having such high conductivity is formed. This is not practical because it is technically difficult, or even if it can be formed, it is 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. When 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 the thickness exceeds 50 μm, the recording layer becomes heavy, and the adsorption force due to static electricity of the opaque film layer cannot support its own weight and easily peels off, making it 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 includes a second resin layer and is adsorbed or adhered to a surface opposite to the one surface having the information of the opaque film layer. The first transparent film layer is formed by, for example, subjecting an opaque film layer to a charging process to be described later and bringing the opaque film layer into contact with the first resin layer of the opaque film layer in which electric charges are accumulated so as to be laminated by electrostatic adsorption. Alternatively, an adhesive layer or an adsorption layer, which will be described later, is provided on the opaque film layer, and the adhesion surface of the adhesion layer or the adsorption surface of the adsorption layer is adhered to or adsorbed on the first resin layer. In the present invention, the transparent film layer means a layer having an opacity of less than 50%. When the opacity of the transparent film layer exceeds 50%, it becomes difficult to observe information through the transparent film layer when the information sheet of the present invention is used as an information display body.
Moreover, when the 1st transparent film layer which comprises the information sheet of this invention contains the resin film similar to the opaque film layer mentioned above, this was charged and the 1st which accumulated the electric charge inside After forming the 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 has an antistatic performance on one side thereof, so that the information sheet combined with the opaque film layer can be configured to have an antistatic performance on both sides. . As a result, in particular, when electrostatic adsorption force is used for adsorption between the opaque film layer and the first transparent film layer, the information sheet that is a laminate does not exhibit electrostatic adsorption force to the outside, Troubles such as sticking to the surroundings and blocking of information sheets during handling such as storage and printing are unlikely to occur, and handling properties are good.

The first transparent film layer is appropriately selected from known materials in consideration of adsorption or adhesion with the opaque film layer and imparting antistatic performance.
The first transparent film layer may have a single layer structure or a multilayer structure composed of two or more layers. In particular, when electrostatic adsorption force is used for adsorption between the opaque film layer and the first transparent film layer, as described above, the first transparent film layer can be electrostatically adsorbed by contacting one side with the opaque film layer. In addition, since the opposite surface is configured to have antistatic performance, it preferably has a multilayer structure.

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, the first transparent film layer is preferably composed of these materials, or has a relative dielectric constant in the range of 1.1 to 5.0 due to processing to form voids therein. When the opaque film layer and the first transparent film layer are laminated, the relative dielectric constant of the first transparent film layer is preferably 1.1 to 5.0, and 1.2 to 4.0. More preferably, it is more preferably 1.5 to 3.0. When the relative permittivity of the first transparent film layer is 5.0 or less, the opaque film layer can retain a charge for a long period of time, and the electrostatic attractive force is unlikely to decrease. 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 having excellent insulating properties from the viewpoint of reducing charge transfer, and the surface resistivity of the surface of the first transparent film layer that contacts 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 difficult to escape to the outside (in the atmosphere, etc.) through the same surface, the opaque film layer can hold the charge for a long time, and the electrostatic adsorption force is 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 that comes to the outer layer of the information sheet for the purpose of imparting antistatic performance to one side.
For imparting antistatic performance to the first transparent film layer, a method of providing the same recording layer (B) used for the opaque film layer, a method of providing a conductive layer by applying a conductive paint, Examples thereof include a method of providing a metal thin film by direct vapor deposition, transfer vapor deposition, lamination of a vapor deposition film, and a method of kneading an antistatic agent into the resin constituting the first transparent film layer.

It is preferable that the surface resistivity of the surface which comes to the outer layer of the information sheet of a 1st transparent film layer exists in the range of 1 * 10 < ^-1 > -9 * 10 < ¹² > (ohm) by the said method. 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 on the outer layer of the information sheet is 9 × 10 ¹² Ω or less, the antistatic performance is sufficient, and the information sheet is attached to the periphery of the information sheet. Troubles such as blocking are unlikely to occur. On the other hand, the surface resistivity is preferably 1 × 10 ⁻¹ Ω or more from the technical viewpoint.
The thickness of the first transparent film layer is preferably 20 to 500 μm, more preferably 25 to 400 μm, still more preferably 30 to 200 μm, and particularly preferably 35 to 150 μm.

On the contrary, when the thickness is 500 μm or less, the obtained information sheet can also be reduced in thickness, 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 is appropriately selected from a known material in consideration of adsorption or adhesion with the second resin film and imparting antistatic performance when electrostatic adsorption is used. The second resin film may be a third transparent film layer. The same material as the first transparent film layer can be used for the second and third transparent film layers, and the adhesive sheet containing the second transparent film layer is manufactured by the same manufacturing method as the information sheet, for example, It can manufacture by the method as described in 2012-145935 gazette.

[Charging treatment]
In the information sheet of the present invention, the opaque film layer is subjected to a charging treatment, and then the first transparent film layer is electrostatically adsorbed by contact with the first transparent film layer, or the first transparent film layer is subjected to a charging treatment and then opaque. It includes a laminate that is brought into contact with the film layer and electrostatically adsorbed.
The method for the charging treatment is not particularly limited, and can be performed according to various known methods. For example, after forming an opaque film layer, a method of applying a corona discharge or a pulsed high voltage to the surface of the opaque film layer, a method of holding both surfaces of the opaque film layer with a dielectric, and applying a DC high voltage to both surfaces (electro Electretization method) and a method of electretization by irradiating an opaque film layer with ionizing radiation such as γ rays and electron beams (radio electretization method).
As a more specific example of the electroelectretization 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 source and a ground electrode (batch type, see FIGS. 12 and 13). ) Or a passing method (continuous, see FIGS. 14 and 15) is desirable. When this method is used, it is desirable to arrange a number of needle-like main electrodes at equal intervals or use metal wires, and use a flat metal plate or metal roll for the counter electrode.
In the present invention, the charging treatment is preferably a direct current corona discharge treatment. The DC corona discharge treatment that can be used in the present invention means that a needle-like or wire-like main electrode (applied electrode) and a plate-like or roll-like counter electrode (ground electrode) are DC-high voltage as illustrated in FIGS. Using a device connected to a power source, an opaque film layer or a first transparent film layer is placed on the counter electrode, and an opaque film layer is generated by corona discharge generated by applying a DC high voltage between the main electrode and the counter electrode. Alternatively, the charge is injected into the first 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 a uniform charging process in the width direction may not be obtained. On the other hand, when the thickness exceeds 50 mm, corona discharge hardly occurs and the opaque film layer or the first transparent film layer may not be uniformly charged.
The voltage applied between the two electrodes is determined by the electrical characteristics 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. Is preferably 1 to 100 KV, more preferably 3 to 70 KV, still more preferably 5 to 50 KV, and particularly preferably 10 to 30 KV. The polarity of the main electrode may be positive or negative, but it is preferable to set the main electrode side to a negative polarity 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 is preferably made of metal such as iron, stainless steel, copper, brass, tungsten, or carbon.
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, it is preferable to set the applied voltage so high that the opaque film layer or the first transparent film layer does not break down.

The charging treatment for the opaque film layer is preferably performed by a method of applying the corona discharge or a high voltage to the surface on the side where the recording layer is not provided. It is preferable that the recording layer has antistatic performance, and such a charging process on the surface is not effective because the applied charge is likely to dissipate to the surroundings through the recording layer. Such a problem does not occur particularly when the recording layer is in contact with the ground side (metal plate or metal roll).
The information sheet, opaque film layer, or first transparent film layer of the present invention can be subjected to a charge removal process after the charging process. By performing the charge removal process, it is possible to avoid troubles in the printing process, the label processing process, and the like. For the charge removal process, a known method such as a voltage application charge remover (ionizer) or a self-discharge charge remover can be used. These general static eliminators can remove charges on the surface, but cannot remove charges accumulated in the resin layer. Therefore, the electrostatic adsorption force of the opaque film layer or the first transparent film layer is not greatly affected by the charge removal treatment.
