- a transparent conductive film in which a layer containing a conductive material (conductive layer) is formed on a support is mainly manufactured by a sputtering method.
- a sputtering method There are various methods in the spattering method. For example, inert gas ions generated by direct current or high-frequency discharge in a vacuum are accelerated and collide with the surface of a target (conductive material or the like), and the atoms constituting the target are exposed to the surface. And a method of forming a transparent conductive layer by depositing the transparent conductive layer on the surface of the support.
- the sputtering method is excellent in that a conductive layer having a low surface electric resistance can be formed even with a relatively large area.
- problems such as the large size of the equipment and the low film formation rate.
- the scale of the device is expected to increase.
- Increasing the scale of the equipment raises technical problems, such as the need for more sophisticated control accuracy, and manufacturing efficiency problems, such as increased manufacturing costs.
- the number of targets is increased to increase the film deposition rate, but this is also one factor in increasing the scale of the equipment.
- a transparent conductive film by a coating method has also been attempted.
- a conductive paint in which conductive fine particles are dispersed in a binder resin is applied to a support and dried to form a conductive layer.
- the coating method has a larger area than the sputtering method.
- the electric layer is easily formed, the equipment is simple, the productivity is high, and the manufacturing cost is low.
- a conductive film formed by a coating method conductive particles existing in a conductive layer come into contact with each other to form an electrical path, thereby exhibiting conductivity.
- a conductive layer cannot be formed unless a large amount of a binder resin is used.
- the binder resin prevents the conductive fine particles from coming into contact with each other, resulting in a problem that the obtained transparent conductive film has a high electric resistance (poor in conductivity), and its use has been limited.
- a coating method without using a binder resin has been attempted, it has been said that in such a case, a conductive layer that can withstand practical use cannot be formed unless the conductive material is sintered at a high temperature.
- Japanese Patent Application Laid-Open No. 9-110959 discloses that a conductive paint composed of a conductive powder and a binder resin is coated on a transfer plastic film, dried, The first step of forming a conductive layer, the second step of applying pressure (5 to: L 0 kg Z cm 2 ) to smooth the surface of the conductive layer and heating (at 70 to: L 80)
- a method for producing an antistatic transparent conductive film or sheet comprising a third step of laminating a conductive layer thus treated on a plastic film or sheet and thermocompression bonding is disclosed.
- a conductive paint containing a large amount of a binder resin is used. That is, when inorganic conductive powder is used as the conductive powder, 100 to 500 parts by weight of the conductive powder is used with respect to 100 parts by weight of the binder, and when the organic conductive powder is used, the binder is used.
- the conductive powder is 0.1 to 30 parts by weight based on 100 parts by weight. Since a large amount of the binder resin is used, a transparent conductive film having a low electric resistance cannot be obtained by the technique disclosed in the above publication.
- the binder is 100 parts by weight with respect to 500 parts by weight of the inorganic conductive powder, which is based on the density of the binder disclosed in the same publication. When converted into the formula, the amount is about 110 for the binder with respect to 100 for the conductive powder.

- a method for producing a glass plate coated with a transparent conductive film is disclosed in which a paint for forming a conductive film containing no binder is applied to a glass plate and fired at a temperature of 300 ° C. or more. In this method, since no binder is used, the electric resistance of the conductive film is reduced. However, since it is necessary to perform the firing step at a temperature of 300 ° C. or higher, it is difficult to form a conductive film on a support such as a resin film. Resin film deforms, melts, carbonizes, or burns at medium to high temperatures. Depending on the type of resin film, for example, in polyethylene terephthalate (PET) film, a temperature around 130 is considered to be the limit of heating.

- the support is finally peeled off.
- the support is not particularly limited, and various supports such as a resin film, glass, and ceramics can be used.
- a support having high transparency and flexibility is preferable.
- a resin film is preferably used.
- resin films include polyester films such as polyethylene terephthalate (PET), polyolefin films such as polyethylene and polypropylene, and polycarbonate.
- PET film an acrylic film, a norpornene film (“A one ton” manufactured by JSR Corporation, etc.) and the like.
- PET film is particularly preferred.
- the thickness of the support is not particularly limited, but is preferably about 10 to 200 / xm.
- the method for producing the transparent conductive film is not particularly limited, but is preferably produced, for example, by the following method.
- the method includes applying a coating material in which conductive fine particles are dispersed on a support, drying the coating to form a conductive fine particle-containing layer, and compressing the conductive fine particle-containing layer to obtain a conductive fine particle compressed layer. And a method for producing a transparent conductive film.

- organic conductive fine particles may be used.
- the particle size of these fine particles varies depending on the degree of scattering required according to the application of the conductive film, and varies depending on the shape of the particles, but cannot be unconditionally determined, but is generally 1 m or less and 0.5 or less. ⁇ m or less is preferable, and 5 to: L00 nm is more preferable.
- the liquid (dispersion medium) in which the conductive fine particles are dispersed is not particularly limited, and various known dispersion media can be used.
- saturated hydrocarbons such as hexane; aromatic hydrocarbons such as toluene and xylene; alcohols such as methanol, ethanol, propanol and butanol; acetone, methylethylketone, methylisobutylketone, and diisobenzene Ketones such as butyl ketone; esters such as ethyl acetate and butyl acetate; ethers such as tetrahydrofuran, dioxane and getyl ether; N, N-dimethylformamide, N-methylpyrrolidone (NMP), N, N— Amides such as dimethylacetamide; halogenated hydrocarbons such as ethylene chloride and chlorobenzene; Above all, dispersion medium with polarity Those having an affinity for water, such as alcohols
- Water can also be used as a dispersion medium. If water is used, the support must be hydrophilic. Resin films are usually hydrophobic and thus repel water easily, making it difficult to obtain a uniform layer. When the support is a resin film, it is necessary to mix alcohol with water or to make the surface of the support hydrophilic.
- the amount of the dispersion medium to be used is not particularly limited as long as the dispersion of the conductive fine particles (paint, conductive paint) has an appropriate viscosity suitable for application. More specifically, the dispersion medium is preferably about 100 to 100,000 parts by weight with respect to 100 parts by weight of the conductive fine particles, but may be appropriately changed depending on the types of the conductive fine particles and the dispersion medium. I can do it.
- Dispersion of the conductive fine particles in the dispersion medium can be performed by a known dispersion means such as a sand grinder mill method. At the time of dispersion, it is also preferable to use a medium such as zirconia beads in order to loosen the aggregation of the conductive fine particles. Also, be careful not to mix impurities such as dust during dispersion.
- the liquid (paint) in which the conductive fine particles are dispersed is expressed by the volume of the resin for the binder by the volume before the dispersion, and when the volume of the conductive fine particles is 100, it is preferable to use the liquid in a range of less than 25. It is preferably less than 20, more preferably less than 3.7, most preferably 0. Resin has the effect of reducing scattering of the conductive film, but on the other hand, increases the electrical resistance of the conductive film. This is because the insulating resin inhibits the contact between the conductive fine particles, and when the amount of the resin is large, the contact between the fine particles is hindered, and the electron transfer between the fine particles is inhibited. Therefore, it is preferable to use the resin within the above-mentioned volume range in consideration of both improvement of transparency and securing of conductivity between the conductive fine particles.
- the volume of the conductive fine particles and the volume of the binder resin are not apparent volumes but true volumes.
- the resin is not particularly limited, and a thermoplastic resin having excellent transparency or a polymer having rubber elasticity can be used alone or in combination of two or more.

- ethylene-tetrafluoroethylene copolymer examples include an ethylene copolymer.
- a fluorine-containing polymer in which hydrogen in the main chain is substituted with an alkyl group can also be used. The higher the density of the resin, the more the volume does not increase even when the amount used increases, so that the requirements of the present invention are easily satisfied.
- additives may be added to the dispersion of the conductive fine particles as long as the conductivity is not impaired. Examples of these additives include an ultraviolet absorber, a sur
- the dispersion (paint) of the conductive fine particles is coated on a support and dried to form a conductive fine particle-containing layer.
- the application of the conductive fine particle dispersion (paint) on the support is particularly limited. Instead, it can be performed by a known method. For example, it can be performed by a coating method such as a reverse roll method, a direct roll method, a blade method, a knife method, an extrusion nozzle method, a curtain method, a gravure roll method, a bar coat method, a dip method, a kiss coat method, and a squeeze method. Further, the dispersion liquid can be attached to the support by spraying or spraying.
- a coating method such as a reverse roll method, a direct roll method, a blade method, a knife method, an extrusion nozzle method, a curtain method, a gravure roll method, a bar coat method, a dip method, a kiss coat method, and a squeeze method.
- the dispersion liquid can be attached to the support by spraying or spraying.
- the drying temperature depends on the type of the dispersion medium used for dispersion, but is preferably in the range of 10 to 150, and when the temperature is lower than 10 ° C, dew condensation of moisture in the air is likely to occur. If it exceeds, the resin film (support) may be deformed. Also, care should be taken so that impurities do not adhere to the surface of the fine particles during drying.
- the thickness of the conductive fine particle-containing layer after coating and drying depends on the compression conditions in the next step and the use of the transparent conductive laminate to be finally applied, but if it is about 0.1 to 10 / xm, Good.
- the conductive fine particles are dispersed in a dispersion medium, applied, and dried, a uniform layer is easily formed.
- a dispersion of these conductive fine particles is applied and dried, the fine particles form a layer even if no binder is present in the dispersion.
- the reason why a layer can be formed without containing a binder is not always clear, but when dried and the amount of liquid in the coating film decreases, the fine particles gather together due to capillary force, and further, the fine particles It means that a layer is formed because the specific surface area is large and the cohesion is strong. However, the strength of the layer at this stage is weak. Further, the resistance value of the conductive film is high, and the resistance value varies widely.
- the formed conductive fine particle-containing layer is compressed to obtain a conductive fine particle compressed layer.
- the strength of the coating film can be improved. That is, the compression increases the contact points between the conductive fine particles and increases the contact surface, thereby increasing the strength of the coating film. Since the fine particles originally tend to agglomerate, compressing them forms a strong layer. In a conductive film, as the strength of the coating increases, the electrical resistance decreases.
- NZmm 2 or more compressive force more preferably 1 3 5 NZmm 2 or more, especially 1 8 0 NZ mm 2 or more. If it is less than 44 N / mm 2 , the conductive fine particle-containing layer cannot be sufficiently compressed, and it is difficult to obtain a conductive film having excellent conductivity.
- the higher the compression force the higher the pressure resistance required for the device.
- a compression force of up to 100 ON / mm 2 is appropriate. Further, it is preferable that the compression is performed at a temperature near normal temperature (15 to 40 ° C). The compression operation at a temperature near room temperature is one of the advantages of the present invention.
- the compression means is not particularly limited, and can be performed by a sheet press, a roll press, or the like, but is preferably performed using a roll press machine.
- Roll pressing is a method of sandwiching a film to be compressed between rolls, compressing the film, and rotating the roll. Roll presses are suitable for high productivity because they can apply high pressure uniformly and can be produced in rolls and toe rolls.
- the roll temperature of the roll press is preferably room temperature (15 to 40).
- a heated atmosphere or in a compression (hot press) in which a roll is heated if the compression pressure is increased, the resin film may be stretched and other problems may occur. If the compression pressure is reduced in order to prevent the resin film of the support from stretching under heating, the mechanical strength of the coating film decreases. In the case of conductive films, the mechanical strength of the coating decreases and the electrical resistance increases.
- a heated atmosphere may be used to reduce the relative humidity of the atmosphere, but the temperature must be within the temperature range where the film does not easily stretch. Generally, the temperature range below the glass transition temperature (secondary transition temperature) is preferred. The temperature should be slightly higher than the required humidity, taking into account the fluctuations in humidity. In the case of continuous compression by a roll press machine, it is also preferable to adjust the temperature so that the roll temperature does not rise due to heat generation.
