[0010]
The polyanion is a polymer with two or more monomer units with an anion group in the molecule. The anion group of the polyanion functions as a dopant with respect to the π-conjugated conductive polymer to improve the conductivity of the π-conjugated conductive polymer,

Among these polyanions, a polymer with a sulfonic acid group is preferred, and polystyrene sulfonic acid is more preferred because it is possible to further improve the conductivity.
The polyanion can be used as a single type alone, or two or more types can be used in combination.
The mass weighted average molecular weight of the polyanion is preferably 20,000 or more and 1,000,000 or less, more preferably 100,000 or more and 500,000 or less.

[0013]
The epoxy compound used in the present embodiment is a compound having an epoxy group and the epoxy group reacts with the anion group of the polyanion to form a chemical bond. Specifically, the epoxy compound is able to coordinate a bond or covalent bond to anion groups of the polyanion, in particular, to excess anion groups that do not contribute to the doping, to render the conductive composite hydrophobic.

As the addition-curable silicone, silicone dissolved or dispersed in an organic solvent is preferably used,
In addition-curable silicone, curing inhibition occurs due to the presence of the amine compound. However, in the coating material for forming a conductive removable layer of the present embodiment, since the conductive composite is dispersible in an organic solvent due to the epoxy compound, it is not necessary to mix an amine compound to make the anion group non-hydrophilic to make. Therefore, it is possible to add the addition-curable silicone in the coating material to form one

A method of making a coating material to form a conductive removable layer to obtain the above-described coating material to form a conductive removable layer comprises a precipitation recovery step and an addition step.
[0043]
The precipitate recovery step is a step of adding an epoxy compound to the aqueous dispersion of the conductive polymer, depositing a conductive composite to obtain a precipitate, and then recovering the precipitate by filtration,
When an epoxy compound is added to the aqueous dispersion of the conductive polymer, at least a portion of the epoxy groups of the epoxy compound react with the anion group of the polyanion. As a result, because the conductive composite becomes hydrophobic, it becomes difficult to stably disperse the conductive composite in the aqueous dispersion, and the conductive composite precipitates in a precipitate.
The aqueous dispersion of the conductive polymer is a dispersion in which a conductive composite containing a π-conjugated conductive polymer and a polyanion forms part of an aqueous dispersion medium,
For example, the aqueous dispersion of the conductive polymer can be obtained by chemically oxidizing and polymerizing a monomer to form a π-conjugated conductive polymer in an aqueous solution of a polyanion. In addition, commercially available aqueous dispersions of conductive polymers can be used.
BE2017 / 5472 [0045]
It is preferred that the water content of the precipitate obtained by the precipitation recovery step is as small as possible and it is most preferred that it contains no moisture at all, but from a practical point of view, there may be a moisture content in the range of 10 mass% or less.
Examples of a method of reducing the water content include a method of washing away precipitation with an organic solvent, a method of drying precipitation and the like,
The addition step is a step of adding an organic solvent, a curable silicone, and a polyester resin to the recovered precipitate.
After the addition of the organic solvent, the curable silicone and the polyester resin to the precipitate, it is preferable to carry out a dispersion treatment by stirring. There is no particular limitation on the stirring method, and the stirring may be low shear stirring such as a stirrer, or the stirring may be performed using a high shear disperser (such as a homogenizer).
In a case where a strong conductive agent, triallyl isocyanurate, additives and the like are contained in the coating material to form a conductive removable layer, the strong conductive agent, triallyl isocyanurate, additives and the like are preferably added after the addition of the organic solvent .
[0047]
In the coating material for forming a conductive removable layer of the present embodiment, it is because the anion group of the polyanion is produced by the
Αν!
epoxy compound non-hydrophilic has been made possible to disperse the conductive composite in the organic solvent with high dispersibility.
The polyester resin is a resin with low air permeability. Therefore it is possible
BE2017 / 5472 to prevent oxidative deterioration of the conductive composite that is part of the conductive removable layer formed from the coating material to form a conductive removable layer and suppress deterioration in conductivity over time in air.
In addition, since the coating material for forming a conductive removable layer comprises the polyester resin, the conductive removable layer formed from the coating material for forming a conductive removable layer, strong adhesion does not have the film base material. In particular, in a case where a polyethylene terephthalate film is used as the film base material of the conductive removable film, the adhesion of the conductive removable layer with the film base material becomes greater.
Because the silicone (polyorganosiloxane) has a lower specific gravity than the polyester resin, the silicone near the surface in the conductive removal layer formed from the coating material to form a conductive removable layer is unevenly distributed, and the polyester resin near the film base material is unevenly distributed. Therefore, for the conductive removable layer formed from the coating material to form a conductive removable layer, it is possible to sufficiently demonstrate a removal property and show strong adhesion with the film base material.
<Conductive film and a method of making it>
A method of making a conductive film according to one embodiment of
BE2017 / 5472 the present invention has a coating step for applying the coating material to form a conductive removable layer on at least one surface of a film base material to form a coated film, and a drying step for heating and drying the applied coating material to form a conductive removable layer.
The conductive film obtained by this production process includes a film base material and a conductive removable layer formed on at least one surface of the film base material, the conductive removable layer containing a conductive composite formed by bonding an epoxy compound, a silicone and a polyester resin.
[0049]
The average thickness of the conductive removable layer is preferably 10 nm or more and 20,000 nm or less, more preferably 20 nm or more and 10,000 nm or less, and even more preferably 30 nm or more and 5,000 nm or less. When the average thickness of the conductive removable layer is the lower limit value or more, it is possible to show sufficiently high conductivity, and at the upper limit value, or less, it is possible to easily form the conductive removable layer.
[0050]
Examples of the film base material used in the coating step of the present embodiment include a plastic film.
Examples of the resin for the film base material constituting the plastic film include ethylene methyl methacrylate copolymer resin, ethylene vinyl acetate copolymer resin, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyvinyl alcohol, polyethylene terephthalate, polybutylene acrylate polythylene, polythylene polyethylene naphthalate, polyethylene naphthalate, polyethylene naphthalate, polyethylene ,
BE2017 / 5472 polyetherimide, polyetheretherketone, polyphenylene sulfide, polyimide, cellulose triacetate, cellulose acetate propionate and the like. Among these resins for a film base material, polyethylene terephthalate and cellulose triacetate are preferred from the viewpoint of inexpensive and excellent mechanical strength, and polyethylene terephthalate is more preferred.
The resin for a film base material can be amorphous or crystalline.
In addition, the film base material can be unstretched or stretched.
In addition, the film base material can be subjected to a surface treatment such as corona discharge, plasma treatment, coating or the like to improve the adhesion of the conductive removable layer formed from the coating material to form a conductive removable layer.
The average thickness of the film base material is preferably 10 µm or more and 500 µm or less, and more preferably 20 µm or more and 200 µm or less. When the average thickness of the film base material is the lower limit value or more, breakage is unlikely to occur, and at the upper limit value or less, it is possible to ensure sufficient flexibility as a film.
The thickness in the present specification is a value obtained by measuring the thickness at random locations and averaging the measured values.
[0052]
As a method of applying the coating material to form a conductive removable layer, it is possible to apply a coating method using a coater such as a gravure coating, a roller coating, a curtain flow coating, a spin coating, a bar coating, an inverse coater, a kiss coater, a fountain coater, a rod coater, an air-doctor coater, a knife coater, a blade coater, a cast coater, a screen coater or the like, a spraying method using a sprayer such as air spraying, airless spraying and rotor damping, an immersion method such as immersion or the like.
Of these, a barcoater can be used because a simple application is possible.
BE2017 / 5472
In the barcoater, the coating thickness varies depending on its type, and in the commercially available barcoater a number is given for each type, and if the number is greater, a thicker coating is possible.
The amount of coating material of the coating material to form a conductive removable layer on the film base material is not specifically limited, but is preferably in the range of 0.1 g / m or more and 10.0 g / m or less in solid content.
[0053]
In the drying step, the coating material to form a conductive removable layer is dried and the curable silicone is cured.
As a heating method in the drying step, it is possible, for example, to adopt conventional methods such as hot air heating and infrared heating. The heating temperature is preferably 50 ° C or higher and 200 ° C or lower, and more preferably
80 ° C or higher and 170 ° C or lower. When the heating temperature is the lower limit value or more, it is possible to sufficiently dry the coating material to form a conductive removable layer and sufficiently cure the curable silicone, and when the heating temperature is the upper limit value or less, it is possible to melt of the film base material.
[0054]
Because the conductive removable film of the present embodiment is formed by applying the coating material to form a conductive
BE2017 / 5472 removable layer on a film base material, the conductive removable layer has strong adhesion to the film base material and suppresses conductivity degradation in air over time. In addition, the conductive removable layer has a sufficient removal property.
According to the method of making a conductive removable film of the present embodiment, it is possible to easily manufacture the conductive removable film described above.

[Measurement of surface resistance value]
The surface resistivity value R _o of the conductive removable layer of the conductive removable film or the conductive layer of the conductive film was obtained immediately after using a Weather Stand Meter (Hiresta, manufactured by Mitsubishi
Chemical Analytech Co., Ltd.) measured under conditions of an applied voltage of 10
V.
In addition, the conductive removable film or the conductive film remained in a condition for 1 day where air the surface of the conductive removable layer or the conductive layer in an environment with a temperature of 25 ° C and a relative humidity of
50% hit, and then the surface resistance value Rj was enjoyed in the same manner as described above.
The measurement results and the values of Rj / Ro are shown in Tables 1 to 3. The smaller the value of Ri / Ro, the smaller the deterioration in conductivity over time in the air.
BE2017 / 5472 [Measurement of release force]
Polyester adhesive tape (No, 3IB, manufactured by Nitto Denko Corporation) with a width of 25 mm was placed on the surface of the conductive removable layer or the conductive layer, and then a load of 1,976 Pa was applied to the adhesive tape and subjected to a heat treatment at 25 ° C for 20 hours to bond the polyester adhesive tape to the conductive removable layer or the conductive layer. Using a tensile tester, the polyester adhesive tape was peeled (pull-out speed: 0.3 m / min) at an angle of 180 ° from the conductive removable layer or the conductive layer, and the release force was measured. The measurement results are shown in Tables 1 to 3, the smaller the release force, the higher the removal property of the conductive removable layer or the conductive layer.
In addition, for comparative purposes, in Comparative Examples 5 and 6, the release force of the removable layer that did not include PEDOT-PSS was measured.
