Description

5. Description of the Invention (1) [Technical Field] The present invention relates to a transparent conductive film using a biaxially-oriented polyester film having a coating layer, and an electron light emitting (hereinafter referred to as EL) board using the same. [Prior art] A transparent conductive film that forms a transparent and low-resistance compound film on a plastic film is widely used in applications that use its conductivity, such as liquid crystal displays, flat displays for EL displays, or transparent electrodes for touch pads. , Electronics applications. Transparent conductive films are typically represented by tin oxide, indium oxide, indium-tin composite oxide, and zinc oxide. The substrate is made of various plastic films mainly composed of polyethylene terephthalate. In recent years, since portable telephones, portable data terminals, and the like have become widespread, attention has been paid to EL panels for such liquid crystal displays. In addition, since the EL panel consumes very little power when it emits light, it is suitable as a light source for portable devices. In addition, along with the enlargement of the display portion and the high definition, there is a strong demand for high luminance of the EL panel and reduction of appearance defects. Conventionally, an EL panel has been produced by a process of sequentially printing an EL light-emitting layer, an electromotive substance layer, a back electrode layer, and an insulating layer on a transparent conductive film of a transparent conductive film. Then, an alternating voltage of about 40 Hz was applied between the transparent conductive film and the back electrode, and a voltage was applied to the light-emitting layer to emit light. The higher the applied voltage, the higher the luminous luminance. In addition, the higher the light transmittance of the transparent conductive film, the higher the brightness of the EL panel. 513731 V. Description of the invention (2) For this requirement, the transparent conductive film used conventionally has the following problems. Generally, a polyester film contains particles to improve its smoothness. However, when such particles are contained in a polyester film, the light transmittance of the polyester film tends to be impaired. In addition, if the polyester film contains no particles or only a few particles in a range that does not impair the light transmittance, it is generally necessary to include particles in the coating layer to improve its smoothness. In this case, in order to ensure transparency, it is necessary to use particles having a wavelength smaller than visible light and having an extremely small average particle diameter. However, although the fine particles having an extremely small average particle size have good transparency, their smoothness is insufficient. Therefore, after the coating process, the film surface is easily injured due to the contact roller. In addition, in the production of EL panels, heat treatment must be performed at 120 to 150 ° C during printing processes such as circuit processing. However, a transparent conductive film using a conventional biaxially-oriented polyester film as a base material may cause problems such as rising of haze or white appearance after the above-mentioned heat treatment. These are the degradation of the visibility or quality of the EL panel, so it is sought to improve the above problems. In order to solve the above-mentioned conventional problems, a first object of the present invention is to provide a transparent conductive film having high light transmittance, excellent scratch resistance, and small change in transparency after heat treatment during post-processing. Furthermore, the second object is to provide an EL panel with few appearance defects such as whitening and excellent visibility. [Disclosure of the Invention] The present invention has been made in view of the above circumstances, and a transparent conductive film and an electron-emitting board using the same in order to solve the above-mentioned problems are as follows.

In the present invention, the biaxially oriented polyester film It can be used as a base material of a transparent conductive film. Raw materials of biaxially oriented polyester films, such as polyethylene terephthalate, polybutylene terephthalate, polyethylene-2,6-naphthoate, and the constituents of these resins are the main components Of these, polyethylene terephthalate is preferred. In the resin forming the biaxially oriented polyester film, when the polyester copolymer is used, the dicarboxylic acid component is, for example, an aliphatic dicarboxylic acid such as adipic acid or sebacic acid, terephthalic acid, isophthalic acid, or phthalic acid. And polyfunctional carboxylic acids such as aromatic dicarboxylic acids such as 2,6-naphthalenedicarboxylic acid, trimellitic acid and trimellitic acid. The alcohol component is, for example, an aliphatic alcohol such as ethylene glycol, diethylene glycol, 1,4-butanediol, propylene glycol, neopentyl glycol, or the like, an aromatic alcohol such as p-xylitol, or 1,4 -Cyclohexanedimethanol and other alicyclic alcohols, polyethylene glycols with an average molecular weight of 150 to 20,000, etc. The preferred copolymer ratio is less than 20%. When it is 20% or more, the film strength, transparency, and heat resistance are not good. Various additives may be contained in the polyester resin. Examples of the additives include an antistatic agent, a UV absorber, and a stabilizer. In addition, it is preferable that the biaxially oriented polyester film does not contain particles in terms of transparency. Moreover, the intrinsic viscosity of the polyester resin used as the starting material of the biaxially oriented polyester film is preferably 0.4 5 to 0.7 d 1 / g. If the intrinsic viscosity is less than 0.45 d 1 / g, the polyester film is prone to rupture in many places during stretching. In addition, if the intrinsic viscosity is greater than 0.7 d 1 / g, the higher the filtration pressure rises, the more difficult it is to filter with high precision. The biaxially oriented polyester film must be provided with a coating layer on at least one side. The above 513731 V. Description of the invention (6) The coating layer is provided on at least one side of the unstretched or uniaxially stretched polyacetate film, and is then applied by the online coating method of at least one axial stretching and heat fixing treatment. Layers are better. When the coating layer laminated by the on-line coating method contains fine particles of an appropriate particle diameter to improve smoothness, it can impart good curlability and scratch resistance. Therefore, it is not necessary to include fine particles in the biaxially oriented polyester film, and high transparency can be maintained. The resin composition constituting the coating layer preferably contains (A) a copolymerized polyester resin and (B) a polyurethane resin. Although the co-polymerized polyester film alone has sufficient adhesion to the polyester film, it does not have sufficient adhesion to the acrylic resin used in the hard coating. In addition, although the polyurethane alone has excellent adhesion to an acrylic resin, it does not have sufficient adhesion to a polyester film. The above-mentioned (A) copolymerized polyester resin is particularly preferably composed of a dicarboxylic acid component and a branched alcohol component. Examples of the branched alcohol component include 2,2-dimethyl-1,3-propanediol, 2-fluorenyl-2-ethyl-1,3-propanediol, and 2-methyl-2-butyl-1 , 3-propanediol, 2-methyl-2-propyl-1,3-propanediol, 2-methyl-2-isopropyl-1,3-propanediol, 2-methyl-2-n-hexyl-1, 3-propanediol, 2,2-diethyl-, 3-propanediol, 2-ethyl-2-n-butyl-1,3-propanediol, 2-ethyl-2-n-hexyl-1,3-propanediol , 2,2-di-n-butyl'1,3-propanediol, 2-n-butyl-2-propyl-1,3-propanediol, and 2,2-di-n-hexyl_1,3-propanediol, etc. . The above-mentioned branched alcohol component is more than 10 mole% in all the alcohol components, and more preferably 20 mole% or more. Alcohols other than the above compounds form a knife, and ethylene glycol is most preferred. In small amounts, ethylene glycol and propylene can also be used.

In addition, (A) the dibasic acid component of the other components of the copolymerized polyester resin is optimal for the present mono-formic acid and isobenzoic acid. It is also possible to add a small amount of altardicarboxylic acid components, especially aromatic dicarboxylic acids such as diphenylcarboxylic acid and 2,6-naphthalenedicarboxylic acid. In addition to the above dicarboxylic acid component, in order to make it water-dispersible, it is preferable to add 1 to 10 mole% 5-sulfoisophthalic acid, such as sulfoterephthalic acid and 5-sulfoisobenzene. Dicarboxylic acid, 4-sulfonaphthalene isophthalic acid-2,7-diresidual acid, 5- (4-sulfophenoxy) isophthalic acid and its salts. The (B) polyurethane has, for example, a block-type isocyanate group-containing resin, the terminal isocyanate group is blocked with a hydrophilic group (hereinafter referred to as a block), and a thermally reactive water-soluble urethane. Esters, etc. Examples of the isocyanate-based block agent include bisulfites and sulfonic acid-containing phenols, alcohols, lactones, oximes, and reactive methylene compounds. Blocked isocyanate groups can render the urethane prepolymer hydrophilic or water-soluble. After the film is applied to the resin, the drying agent or heat-fixing treatment process is used to make the resin have thermal energy. Since the blocking agent is detached from the isocyanate group, the resin can be mixed with water-dispersible copolymers which are cross-linked by itself. The polymerized polyester resin is immobilized and reacts with a terminal group or the like of the resin. Because the resin in the coating liquid adjustment is hydrophilic, its water resistance is not good. When the thermal reaction of coating, drying and heat fixing is completed, the hydrophilic group (ie, the blocking agent) of the urethane resin is detached. Therefore, a coating film with good water resistance can be obtained. Among the above-mentioned block agents, at an appropriate heat treatment temperature and heat treatment time 513731 V. Description of the invention (8) It is preferable to use bisulfites which are widely used industrially. The chemical composition of the urethane prepolymer used in the (B) polyurethane resin is (a) an organic polyisocyanate having two or more active hydrogen atoms in the molecule, or having at least two Compounds with two active hydrogen atoms and a molecular weight of 200 to 20,000, (b) an organic polyisocyanate having more than two isocyanate groups in the molecule, or (c) a chain elongation agent obtained by reacting at least two active hydrogen atoms in the molecule Compounds with isocyanate groups at the ends. The compounds generally known as (a) above are those having two or more hydroxyl, carboxyl, amine, or thiol groups in the terminal or molecule. More preferred compounds include polyether polyols and polyether ester polyols. Wait. Polyether polyols include, for example, compounds that polymerize alkylene oxide groups such as ethylene oxide and propylene oxide, or styrene oxide and epichlorohydrin, or random polymerization, block polymerization, or addition of polyols. Into a compound obtained by polymerization. Polyether polyols and polyether ester polyols are, for example, linear or branched compounds. By using polysaturated or unsaturated carboxylic acids such as succinic acid, adipic acid, benzoic acid, and maleic anhydride, or the carboxylic acid anhydrides, etc., it can be combined with ethylene glycol, diethylene glycol, 1,4-butanediol, Polysaturated and unsaturated alcohols such as neopentyl alcohol, 1,6-hexanediol and trimethylolpropane, lower molecular weight polyethylene glycols and polyalkylene glycols such as polypropylene glycol, or the like The mixture is obtained by condensation. In addition, polyester polyols can use polyesters obtained from lactones and hydroxide acids, and polyetherester polyols can be used in addition to pre-manufactured polyesters. Ethylene oxide-10-513731 V. Description of the invention ( 9) Polyether esters of olefin or propylene oxide. The (b) organic polyisocyanate includes, for example, isoforms of methylphenylene diisocyanate, aromatic isocyanates such as 4,4-diphenylmethane diisocyanate, and aromatic fats such as phenyldimethyl diisocyanate. Alicyclic diisocyanates such as diisocyanates, isophorone diisocyanates, 4,4-dicyclohexylmethane diisocyanates, hexamethylene diisocyanates, and 2,2,4-trimethylhexanes Aliphatic diisocyanates, such as methylene diisocyanate, or polyisocyanates, such as trimethylolpropane, which are previously added to these compounds in one or more groups. (C) The chain elongating agent having at least two active hydrogens includes, for example, alcohols such as ethylene glycol, diethylene glycol, 1,4-butanediol, and 1,6-hexanediol, glycerol, Polyols such as trimethylolpropane and pentaerythritol, diamines such as ethylenediamine, hexamethylenediamine, and piperazine, alcoholamines such as monoethanolamine and diethanolamine, and disulfide diethylene glycol When the urethane is prepolymerized with alcohols or water, it is usually carried out by using the one-stage or multi-stage isocyanate polyaddition method of the above-mentioned chain extender at a temperature of 15 ° C or less (preferably 70 to 120 ° C ) At a temperature of 5 minutes to several hours. The ratio of isocyanate groups to the active hydrogen atom can be freely selected from the range of 1 or more, but free isocyanate must remain in the urethane prepolymer obtained. In addition, the content of free isocyanate groups is 10% by weight or less, and 7% by weight is preferable in consideration of the stability of the aqueous urethane prepolymer solution after block formation. The obtained amine group Formate prepolymers are carried out using bisulfite-11-513731 V. The invention (10) Blocking is preferred. Mix with bisulfite aqueous solution for about 5 minutes to 1 hour and stir uniformly for reaction. The reaction temperature is preferably 6 ° C or lower. Then, dilute with water to the appropriate Concentration to form a thermally reactive water-soluble urethane composition. When using this composition, adjust the appropriate concentration and viscosity, but usually due to the heavy sulfite of the blocker when heated around 80 ~ 200 ° C Dissociates and regenerates active isocyanate groups, so it has the property of generating a polyurethane polymer by causing a polyaddition reaction within or between molecules of the prepolymer, and causing addition to other functional groups. The above-mentioned (B Μ block-type isocyanate group-containing resins include, for example, Yara Stanlon, a trade name of Daiichi Kogyo Pharmaceutical Co., Ltd.). The Yara Stanlon system is to make isocyanate groups by sodium bisulfite Blockers have strong hydrophilicity at the molecular ends and the presence of aminomethyl sulfonate groups, so they are water-soluble. The copolymerization (Af) of the branched-chain alcohol component used in the present invention is copolymerized and polymerized. Ester resin and (B ') When the segment-type isocyanate group-containing resin is mixed to adjust the coating liquid, the weight ratio of (AJ resin to (B ') resin is (A'): (B ·) = 90: 10 to 10: 90 is better, more preferably (A '): (B') = 80: 20 ~ 20: 80. If the ratio of the (A ') resin to the weight of the solid content is less than 10% by weight, the coating property to the substrate film Poor, the adhesion between the surface layer and the film is insufficient. If the proportion of the (B ') resin is less than 10% by weight based on the weight of the solid content, it cannot be practically used in UV-curing hard coating Adhesiveness. In the present invention, an aqueous coating is used when forming a coating liquid for a coating layer. -12-513731 V. Description of the invention (11) The coating liquid is preferred. The aqueous coating liquid is in a range that does not damage the adhesiveness. Various additives such as antistatic agents, ultraviolet absorbers, plasticizers, pigments, organic fillers, and lubricants can also be mixed therein. In addition, in order to make the coating liquid water-based, other water-soluble resins, water-dispersible resins, emulsions, and the like may be added to the coating liquid as long as the adhesion is not impaired.

To promote the thermal crosslinking reaction in the aqueous coating solution, various chemicals such as inorganic substances, salts, organic substances, alkaline substances, acid substances, and metal-containing organic compounds may be added. When adjusting the pH of the aqueous solution, an alkaline substance or an acidic substance may be added. When the above-mentioned aqueous coating solution is applied to the surface of a substrate film, in order to improve the wettability of the film and uniformly apply the coating solution, a necessary amount of a conventional anionic surfactant and a non-ionic interface are added. Active agents are preferred. The solvent used in the coating liquid may be mixed with alcohols such as ethanol, isopropyl alcohol, benzyl alcohol, and the like in a proportion of less than 50% by weight of the entire coating liquid, in addition to water.

When it is less than 10% by weight, organic solvents other than alcohols may be mixed in a soluble range. However, the total amount of the alcohols and other organic solvents in the coating liquid is preferably less than 50% by weight. When the organic solvent is added in an amount of less than 50% by weight, the drying property after coating can be improved, and the appearance of the coating layer is better when compared with that with only water. If it is 50% by weight or more, the evaporation rate of the solvent will be high, the concentration of the coating solution will change, the viscosity will increase, and the coatability will decrease, which may cause the appearance of the coating film to be poor, and there may be dangers of flooding, etc. Sex. In addition, the coating amount (the solid content weight per unit area of the film) is preferably from 0.05 to 513731. V. Description of the Invention (彳 2) to 0.50 g / m2 is preferred. If the coating amount is less than 0.05 g / m2, the adhesion is not good. When the coating amount is more than 0.50 g / m2, the total light transmittance is reduced and it is not desirable. The total light transmittance of the biaxially oriented polyester film must be more than 90%, more preferably 91% or more, and more preferably 92% or more. If the total light transmittance is less than 90%, the total light transmittance as a transparent conductive film is insufficient, so it is not desirable. When the total light transmittance of the biaxially oriented polyester film is 90% or more, it is preferred that particles are not included in the base film. When particles are not contained in the base film, it is preferable to include appropriate particles in the coating layer in order to improve the scratch resistance of the coating layer and the curlability of the film. Examples of the particles include inorganic particles such as calcium carbonate, calcium phosphate, silicon dioxide, glass filler, kaolin, talc, titanium dioxide, aluminum oxide, barium sulfate, calcium fluoride, lithium fluoride, zeolite, and molybdenum dioxide. Organic particles such as polymer particles, siloxane resin particles, calcium oxalate, etc. Among them, silicon dioxide particles are preferable because they have a refractive index close to that of a polyester resin, and it is easy to obtain a high transparent film. It is preferable that the coating layer of the biaxially oriented polyester film contains two kinds of particles (particle A and particle B). The average particle diameter of the particles A is preferably 20 to 300 nm, and more preferably 30 to 100 nm. If the average particle diameter of the particles A is less than 2 nm, the scratch resistance tends to be poor. In addition, if the average particle diameter of the particles a is larger than 300 nm, the total light transmittance tends to be too low. In the present invention, particle B is used in particle A to further improve scratch resistance. -14- 513731 5. Description of the invention (13). The average particle diameter of the particles B is preferably 300 to 100 nm, and more preferably 400 to 800 nm. If the average particle diameter of the particles B is less than 300 nm, the scratch resistance tends to be poor. In addition, if the average particle diameter of the particles B is more than 100 nm, the total light transmittance tends to be too low. Further, the aggregated particles in which the particles B are aggregated as primary particles are preferable. The average particle diameter of the particles B in the aggregated state is 6 times or more the ratio of the average particle diameter of the primary particles, so it is desirable in terms of scratch resistance. In addition, the content ratio (A / B) of particles A to particles B in the coating layer is 5 to 30, and the content of particles B is 0.1 to 1% by weight based on the solid content of the coating layer. The average surface thickness (SRa) of the secondary center plane of the layer surface is preferably 0.002 to 0.010 // m, and the content of each particle must be set within the above range. Especially for the resin composition of the coating layer, when the content of the particles B is more than 1% by weight, the total light transmittance is significantly reduced. The resin composition of the coating layer described above refers to the solid content of resin A, resin B, particles A, and particles B. In addition, when the total light transmittance of the biaxially oriented polyester film is 90% or more, the foreign matter in the coating liquid and the substrate polyester film can be effectively removed, and the entire sheet when the unstretched sheet is made. (Especially the surface that is not in contact with the chill roll). In order to precisely filter the coating liquid, the particle size (initial filtration efficiency: 95%) is preferably 25 # m or less. If the filter particle size is larger than 2 5 # m, the effect of removing coarse aggregates is insufficient. Therefore, the coarse aggregates that cannot be removed by filtration will be enlarged due to the tensile stress of the uniaxial stretching or biaxial stretching process after coating and drying, and the aggregation is 100 # m or more -15- 513731 V. Description of the invention (14 The reason is that the total light transmittance of the film is reduced. The type of the filter material for precise filtration of the coating liquid is not particularly limited as long as it has the above-mentioned properties, such as a monofilament type, a felt type, and a screen type. The material of the filter medium for precise filtration of the coating liquid is not particularly limited as long as it has the above-mentioned properties and does not adversely affect the coating liquid, such as stainless steel, polyethylene, polypropylene, and nylon. When the base polyester film is to remove foreign matter contained in the raw polyester resin, the molten polyester resin is maintained at an arbitrary state of about 280 ° C during melt extrusion and filtered with high precision. The filter material used for high-precision filtration of molten polyester resin is not particularly limited, but it is not a condensate (catalyst) containing Si, Ti, Sb, Ge, Cu as the main component when filtering materials for steel baking products. Or cause of contamination) and high-melting polyesters are preferred. The filter particle size (initial filtration efficiency: 95%) of the filter material used for high-precision filtration of the molten polyester resin is preferably 15 or less. If the particle size of the filter material is greater than 1 5 // m, it is not easy to sufficiently remove foreign matter above 20 0 m. By using a filter material with a filter particle size (initial filtration efficiency: 95%) of 15 / zm or less, high-precision filtration of molten polyester resin is used to reduce productivity, which is extremely suitable for obtaining biaxial alignment with high total light transmittance. Polyester film. In the above-mentioned high-precision filtration, even if there is a fine foreign substance passing through the filter material, during the cooling filtration during the manufacture of the unstretched polyester sheet, the surrounding crystals are crystallized, and this substance may cause stretching in the stretching process. Uniformity, and it is a state of a lens that produces a minute thickness difference. Here, tortuosity or scattering occurs when there is light, which is larger than the actual foreign matter when viewed with the naked eye. The difference between this tiny foreign body can be observed the height of the convex portion and the depth of the concave portion, and the height of the convex portion

-16- 513731 V. Description of the invention (彳 5) When the shape is 1 // m or more and the depth of the recess adjacent to the convex part is 0.5 or more, even if the size is 2 0 // m, the shape object When viewed with the naked eye, a size of 50 / zm or more can be seen. In addition, it can be seen that there are also optical defects of a size of 100 // m or more. In order to obtain a highly transparent film, it is desirable to not include particles in the base film to make the particles slippery, but the smaller the amount of particles added, the higher the transparency, and the optical defects due to the small unevenness will be worsened. Sharp tendency. In addition, since the surface of a thick film is harder to be rapidly cooled than a film and tends to crystallize, the entire film must be rapidly cooled when an unstretched sheet is formed. The method of quenching an unstretched sheet is a conventional method of making a molten resin from a mold on a rotary cooling tube to the sheet, and tightly contacting the sheet-like molten material to the rotary cooling tube and quenching. The method of cooling the air surface (the surface opposite to the contact surface of the cooling tube) of the sheet-like object is effective by cooling by blowing high-speed air. Next, the manufacturing method of the biaxially-oriented polyester film used as the base material of the transparent conductive film of the present invention can be explained by using polyethylene terephthalate (hereinafter referred to as PET) as an example, but it is not limited by these . The PET resin pellets substantially free of particles are fully vacuum-dried and then supplied to an extruder, melted and extruded into a sheet shape at about 28 ° C., and cooled and solidified to form an unstretched PET sheet. At this time, the molten resin is maintained at an arbitrary state of about 280 ° C, and the above-mentioned high-precision filtration is performed to remove foreign substances contained in the resin. The obtained unstretched PET sheet is heated to 80 to 120 It is stretched by 2 · 5 ~ 5 · 0 times in the direction of ° C to obtain a uniaxially stretched PET film. In addition, the ends of the film are fixed with paper clips and heated to 80 ~ -17-513731 V. Description of the invention (16) In the hot air zone of 180C, it is stretched 2.5 to 5.0 times in the direction of visibility after drying. Then, the heat treatment zone of 160 to 240 ° C is continuously introduced, and the heat treatment is performed for 1 to 60 seconds. Crystallization alignment is completed. In this heat treatment process, a relaxation treatment of 1 to 12% in the width direction or the length direction can be applied as required. In any stage of the process, the above-mentioned copolymerization is coated on one or both sides of the PET film. Polyester and polyurethane resin aqueous solution. Apply the above-mentioned aqueous coating liquid It can be performed by any conventional method, for example, reversible roll, coating method, gravure coating method, contact coating method, roll brush method, spray coating method, air blade coating method, wire rod coating method, tubular blade method , Impregnation coating method, curtain coating method, etc. These methods can be used alone or in combination. The process of coating the above-mentioned aqueous coating solution can be a general coating process, that is, heat fixing by biaxial stretching The process of coating the base PET film is preferably the in-line coating method applied in the process of manufacturing the PET film. The more preferred is coating on the base PET film before the crystal alignment is completed. Water-based coating The solid content concentration of the liquid is preferably 30% by weight or less, more preferably 10% by weight or less. The PET film coated with the aqueous coating liquid is unstretched and heat-fixed, introduced into a tenter, and then heated. In order to form a more stable film by thermal cross-linking reaction, a laminated PET film is formed. In addition, when other layers are laminated on the coating layer, in order to obtain good adhesion with other layers, the coating amount applied to the PET film is 0.05g / m2 or more, must be heat treated at 100 ° C for more than 1 minute The average surface roughness (SRa) of the three-dimensional center plane of the coating layer surface of the biaxially oriented PET film must be 0.002 ~ 0.010 / im, preferably 0.0025

If the SRa is less than 0.002 β m, the scratch resistance of a smooth surface deteriorates, which is not desirable. In addition, when the right SRa is greater than 0.010 // ΓΠ, the total light transmittance is reduced and the transparency is not good, so it is not desirable to use it as a base material of a transparent conductive film. When the content and ratio of particles A and particles B and the coating amount are within the above-mentioned ranges, the ranges of SRa and total light transmittance specified in the present invention are suitable, which is extremely effective in achieving both transparency and scratch resistance. . The thus obtained biaxially oriented PET film with a coating layer is characterized by excellent transparency, adhesion, and excellent scratch resistance in a post-processing process. The thickness of the biaxially oriented PET film is preferably 10 // m to 300 #m, and more preferably 70 to 260 / zm. When the thickness of the film is less than 10 // m, the waist (stiffness) of the film is insufficient, and the durability tends to be poor. In addition, if it is more than 300 / ζιώ, the light transmittance is too high, which is not desirable. Moreover, the characteristics of a lightweight film are not seen. The biaxially oriented PET film may be subjected to a surface treatment such as a corona discharge treatment or a light emitting discharge treatment without impairing the object of the present invention. When a transparent conductive film using a biaxially oriented PET film as a substrate is used as a transparent electrode of an EL panel, heat treatment is performed at 100 to 150 ° C in a printing process such as circuit processing. By this heat treatment, there are cases where the appearance of mist or turbidity rises or the appearance is white. Here, the inventors focused on the heating of the biaxially oriented PET film, the main reason for the increase in haze and whiteness is the oligomer. • 19-513731 V. Description of the invention (18) Cyclic terpolymers, and the results of in-depth investigations, it was found that the content of cyclic terpolymers contained in the raw material PET resin and the retention time up to the mold in the film-making process of the PET film were significant The effect of polymer content is greatest. As a result, it was found that the content of the cyclic terpolymer contained in the film is preferably 5,000 ppm or less, and more preferably 4500 ppm or less, and it is possible to suppress an increase in haze after heat treatment. In order to reduce the typical amount of oligomers of cyclic trimers, it is better to first make the PET resin in the inert gas atmosphere such as nitrogen under a specific pressure and temperature range to perform oligomerization treatment for a specific time. The pressure condition is preferably 1 to 2 atmospheres, and more preferably 1 to 1.4 atmospheres. The heating temperature is 180 ° C to 250 ° C, and more preferably 200 ° C to 230 ° C. The processing time is preferably 12 hours to 36 hours. At this time, when there is oxygen in the atmosphere, the coloration problem occurs due to the oxidation reaction; when water vapor is present, the degree of polymerization of PET is reduced due to the hydrolysis reaction and the film strength is reduced. When the atmospheric pressure in the inert gas atmosphere is lower than 1 atmosphere, a specially designed device must be installed in order to prevent outside air, oxygen, and water vapor from entering. In addition, even when the air pressure in the inert gas atmosphere is greater than 2 air pressure, the reduction effect of the oligomer remains unchanged. When the temperature of the oligomerization treatment is higher than 250 ° C, the PET resin may cause problems such as melting or discoloration. In addition, when the temperature is lower than 18 ° C, the reduction effect of the oligomer tends to be insufficient. In addition, even if the processing time is longer than 36 hours, the effect of increasing the haze due to the heat treatment of the film will not be affected. 20- V. Description of the invention (19) After the low oligomer treatment of PET resin, it is better to use inactivation treatment to reduce catalyst activity. For example, by chemical treatment such as oxidation, reduction, hydration, and / or sonication, Physical treatment such as electromagnetic wave irradiation to reduce catalyst activity or inactivation. In addition, chemical modification such as etherification is applied to the alcohol end of PET to suppress oligomer regeneration reaction such as cyclic trimer. When the catalyst is deactivated or oligomer regeneration inhibited, the raw material PET resin is melted during the production of the film, and the oligomer is regenerated at the same time as the time elapses. Therefore, the PET resin is melted until it is extruded. The cooling residence time is controlled within 20 minutes, preferably within 12 minutes, which can suppress the content of the cyclic terpolymer in the biaxially oriented PET film to be less than 5000 ppm, and can produce haze after heating. rise In addition, the oligomers on the surface of the film are segregated by heat-fixing treatment during film formation, so that the amount of oligomers on the surface of the film is 0.5 mg / m2 or less. Heat treatment causes the haze to rise or produce a white appearance defect. When the amount of oligomer on the surface is 0.5 mg / m2 or less, the heat-fixing treatment temperature during film formation is 2 3 5 t or less. The temperature is preferably 230 ° C or lower. In addition, in order to prevent the haze from rising due to heat treatment, a cross-linked resin is provided on the surface of the transparent conductive film where the transparent conductive layer is not formed. The thin film layer is an extremely effective means. With this thin film layer made of a crosslinked resin, the oligomer block precipitated from the film by heating can be prevented from being used in printing processes such as circuit processing. Heat treatment -21-513731 V. Description of the invention (20) The appearance of haze and rising or white appearance defects may occur. In order to make the oligomer block with low molecular weight, it is necessary to cross-link the resin The mesh structure is smaller than that of oligomers. In the case of a mesh structure, a cross-linked resin having a large number of cross-linking points and a low molecular weight is preferred. In other words, the thin-film layer formed of the cross-linked resin is a multi-functional cross-linking having three or more functions. It is formed by a type resin, and the functional groups are formed between the functional groups and / or the functional group and the bifunctional resin added to the film layer in advance or as a result of reaction with water. The film layer formed from the crosslinked resin mainly contains A polyfunctional isocyanate-based resin and / or a polyfunctional epoxy-based resin as a polyfunctional cross-linked resin component are preferred. A polyfunctional isocyanate-based resin and / or a polyfunctional ring used in a film layer made of a cross-linked resin. The oxygen-based resin is preferably a resin having an initial molecular weight of 2,000 or less equivalent to a trifunctional group. The more preferable is 1500 or less, and the most preferable is 1,000 or less. A resin having a minimum number of chemical bonds between functional groups of 50 or less is preferred. More preferably, it is 30 or less, and the most preferable is 20 or less. When the initial molecular weight or the number of chemical bonds between functional groups is too large, the mesh structure of the crosslinked mesh formed by the reaction is too large, and the whitening inhibitory effect is insufficient. The polyfunctional isocyanate-based resin includes, for example, a low-molecular or high-molecular aromatic, an aliphatic isocyanate, and a trivalent or higher polyisocyanate. Polyisocyanates having a trivalent or higher value include, for example, tetramethylene diisocyanate, hexamethylene diisocyanate, tolyl diisocyanate, diphenyl diisocyanate-22-513731 5. Description of the invention ( 21) Alkyl esters, hydrogenated diphenylmethanyl diisocyanate, xylyl diisocyanate, xylyl hydrogenated diisocyanate, isophorone diisocyanate, and other isocyanate compounds Trimer. In addition, the excess of these isocyanate compounds is related to low-molecular active cyanides such as ethylene glycol, propylene glycol, trimethylolpropane, glycerol, sorbitol, ethylenediamine, monoethanolamine, diethanolamine, and triethanolamine. Or a compound having an isocyanate group at the end obtained by the reaction of a polymer active hydride such as polyester polyols, polyether polyols, polyamines, and the like. Polyfunctional epoxy resins such as diglycidyl ether of bisphenol A and its oligomers, diglycidyl ether of hydrogenated bisphenol A and its oligomers, diglycidyl orthophthalate, isopropyl Diglycidylphthalate, Diglycid terephthalate, Diglycidyl para-benzoic acid, Diglycidyl tetrahydrophthalate, Diglycidyl hexahydrophthalate Esters, diglycidyl succinate, diglycidyl adipate, diglycidyl sebacate, ethylene glycol diglycidyl ester, propylene glycol diglycidyl ester, 1,4-butadiene Alcohol diglycidyl, 1,6-hexanediol diglycidyl and polyalkylene glycol diglycidyl, triglycidyl trimellitic acid, triglycidyl isocyanate, 1,4-Diglycidyloxybenzene, Triglycidylpropylene urea, Glycerol Triglycidyl, Trimethylolpropane Triglycidyl, Pentaerythritol Triglycidyl, Glycerol Triglycidyl ethers of alkenyl oxide adducts, etc. In addition, when the number of chemical bonds between functional groups is 7 or less, when the thin film layer formed of the crosslinked resin to be formed is bent, cracks and curls are liable to occur. To ease it, you can mix other tree moon purposes. The blending amount of other resins is preferably 70% by weight or less for cross-linked resins made of isocyanate-based resins and / or epoxy. If it is more than 70% by weight, the crosslinked mesh is too large, and the whitening suppression effect during heating is insufficient. Examples of the resin to be mixed in the above-mentioned crosslinked resin include polyester resin, acrylic resin, methacrylic resin, urethane resin, melamine resin, and polysiloxane resin. Among these, copolymerized polyester resins are the best. The copolymerized polyester resin is composed of an alcohol component and a dicarboxylic acid component. The alcohol component is best with ethylene glycol. It may also contain diethylene glycol, propylene glycol, butanediol, neopentyl alcohol, hexanediol, 1,4-cyclohexanedimethanol, and the like. The dicarboxylic acid component is preferably terephthalic acid and isophthalic acid. It is also possible to add a small amount of other dicarboxylic acids (especially diphenyl dicarboxylic acids and aromatic dicarboxylic acids such as 2,6-fluorenedicarboxylic acid) for copolymerization. The thickness of the thin film layer made of the crosslinked resin is preferably 0.05 to 3.0 // m in order to prevent the oligomer from precipitating. More preferably, it is 0.1 to 2.0 // m. If the thickness of the thin film layer is more than 3.0 # m, the bending resistance is insufficient; while if it is less than 0.05 // m, the effect of preventing the oligomer precipitation is insufficient. A method in which a film made of a crosslinked resin is laminated on a biaxially oriented PET film is preferably a coating method. In addition, the coating liquid containing a cross-linked resin may be added with a catalyst for promoting a thermal cross-linking reaction, such as various chemical substances such as inorganic substances, salts, organic substances, basic substances, acid substances, and metal-organic compounds. The coating method can be air blade coating method, knife coating method, iron coating method, forward rotation roller coating method, reversible coating method, gravure coating -24- 513731

V. Description of the invention (23) method, contact coating method, bead coating method, longitudinal slit hole coating method, mold coating method, etc. In the case of having a crosslinked structure, energy is applied by heating, ultraviolet rays, or electron beam irradiation after coating. In addition, when a coating solution containing a crosslinked resin is applied to a film, in order to improve the adhesion, the film may be subjected to a surface treatment such as a corona discharge treatment, a light emission discharge treatment, or the like in advance. The transparent conductive film of the present invention is not particularly limited as long as it has transparency and conductivity. Typical examples include indium oxide, zinc oxide, tin oxide, indium-tin composite oxide, tin-antimony composite oxide, and zinc- Thin film of aluminum composite oxide, indium-zinc composite oxide, etc. These compound films are produced under appropriate production conditions and are known to be transparent conductive films having transparency and conductivity. Methods for forming transparent conductive films include vacuum evaporation, sputtering, CVD, ion plate, and spray methods, which are known. Depending on the type of the materials and the required film thickness, appropriate conventional methods can be used. . In the case of a sputtering method, for example, a general sputtering method using a compound or a reactive sputtering method using a metal target can be used. At this time, oxygen, nitrogen, water vapor, and the like of the reactive gas are introduced, and ozone is added and ions are assisted. In addition, a bias voltage such as DC, AC, or high frequency is applied to the substrate. The same applies to other preparation methods such as the vapor melting method and the CVD method. In order to reduce the surface resistance of the transparent conductive film, generally, the film thickness of the transparent conductive film is increased, and conversely, there is a problem that the light transmittance is decreased. In addition, if the film thickness of the transparent conductive film is too thick, it is likely to be curled due to the heat treatment at the time of making the plate when EL -25-513731 V. Description of the Invention (24) The problem that the productivity may be lowered may occur as a result. Furthermore, the present inventors have found that when the transparent conductive film has a certain thickness, the light transmittance can be improved. For example, in the case of an indium-tin composite oxide, a film thickness of 80 nm or more can improve light transmittance. The reflected light on the surface of this transparent conductive film interferes with the reflected light at the interface of the biaxially oriented PET film and the transparent conductive film to cancel each other out, weakening the reflected light, and increasing the transmitted light by reducing the reflected light. , And then increase the light transmittance. In other words, when the refractive index of the transparent conductive film is N, the film thickness of the transparent conductive film is D, and the wavelength at which the light transmittance is highest is λ, NXD = (λ / 2) X η satisfies the above formula to adjust the transparent conductivity The thickness of the thin film. Here, η is an integer of 1 or more. For example, when the light transmittance of 550nm is the highest, the film thickness is 137.5nm, 275.Onm, 412 · 5nm (corresponding to n = 1, 2, 3), etc. when using an indium-tin composite oxide with a refractive index of 2. . The wavelength with the highest light transmittance is preferably 450 nm to 600 nm. Since the wavelength of less than 450nm is shorter than the wavelength of visible light, it is not possible to increase its luminous brightness when used in an EL panel. When designing a long wavelength longer than 600 nm, the transmittance at 500 nm is insufficient, so it is still not possible to improve the luminous brightness when used in an EL panel. In addition, the transmittance at the design wavelength is preferably 80% to 97%. In order to make the light transmittance high, the above reflected light is designed because of the interference effect. -26- 513731 V. Description of the invention (25) is minimized, so the absorption of the transparent conductive film must be small. Therefore, it is necessary to increase the oxidation degree of the transparent conductive film as much as possible. However, when the light transmittance is greater than 97%, the degree of oxidation is increased, so that the surface resistance becomes extremely small, making it unsuitable as a transparent electrode for an EL panel. The surface resistance of the transparent conductive film is preferably 10 to 100 Ω / □. When the surface resistance is less than 10 Ω / □, the thickness of the transparent conductive film must be made extremely thick, and characteristics such as bending processing are insufficient. If the surface resistance is greater than 100Ω / □, the effect of increasing the luminous brightness when used in an EL panel is insufficient. In addition, when the thickness of the transparent conductive film is simply set to a thickness of 80 nm or more as much as possible, curling tends to occur during the heat treatment in the printing process of the post process. As a result, the engineering passability is not good and productivity is reduced. Therefore, after the transparent conductive film is heat-treated at 150 ° C. for 3 hours, a bending amount of 30 mm × 30 mm is preferably 2 mm or less. When the bending amount is 2 mm or less, the dimensional shrinkage of the transparent conductive film is preferably 0.2% or less after heat treatment at 150 ° C for 3 hours. When the dimensional shrinkage after heat treatment at 150 ° C for 3 hours is greater than 0.2%, curling is likely to occur in the printing process when manufacturing an EL panel. Therefore, there is a tendency that the engineering passability is not good and the productivity is lowered. In order to reduce the dimensional change due to the heat treatment, it is preferable to perform heat treatment on the transparent conductive film in advance or to provide a thin film layer made of the above-mentioned crosslinked resin. When heat-treating a transparent conductive film of a transparent conductive film, it is preferable to perform an on-line treatment at a temperature of 200 to 240 ° C in a heat-fixing process for manufacturing a biaxially oriented PET film. If the heat-fixing treatment is less than 200 ° C, -27- 513731 V. Description of the invention (26) The effect of reducing the heat treatment size shrinkage during post-processing is not sufficient. In addition, when it is higher than 240 ° C, it is not easy to stabilize the biaxially oriented PET film and form a film. Moreover, the coating agent containing a cross-linking resin may be coated on the biaxially oriented PET film when not on the line, and a heat treatment for drying and hardening the coating agent may be applied, and simultaneously performed by the heat Low shrinkage processing. In order to dry, harden, and reduce the size shrinkage of the transparent conductive film of a thin film layer made of a crosslinked resin, the temperature of the drying furnace is preferably 120 to 240 ° C. If it is less than 120 ° C, the effect of reducing the dimensional shrinkage after heat treatment is insufficient. If it is higher than 240 ° C, the planarity of the biaxially-oriented PET film tends to decrease. In the transparent conductive film of the present invention, a thin film of an attractor is laminated on the transparent conductive film to prevent the transparent conductive film from becoming black when a transparent electrode used in an EL panel is used. This blackening mechanism is caused by a voltage applied to the light-emitting layer when used in an EL panel to move electrons, thereby reducing and darkening the transparent conductive film. Examples of the electromotive materials used in the present invention include boron oxide, magnesium oxide, aluminum oxide, sand oxide, titanium oxide, oxide pins, oxide oxide, manganese oxide, iron oxide, cobalt oxide, nickel oxide, copper oxide, zinc oxide, and oxide. Iridium, zirconia, niobium oxide, molybdenum oxide, lead oxide, tin oxide, antimony oxide, barium oxide, bell oxide, hafnium oxide, tungsten oxide, platinum oxide, bismuth oxide, barium titanate, lead titanate, potassium niobate, Lithium niobate, lithium giant acid, lead sulfate, carbowate, thorium sulfate, zinc sulfide, sand nitride, silver bromide, silver chloride, etc. These can be used alone or in combination of two or more. -28- 513731 V. Description of the invention (27) Titanium oxide is suitable for these materials. The non-inductive rate of titanium oxide is 170, which is extremely high. When the transparent conductive film of the present invention in which titanium oxide is laminated is used in an EL panel, it can effectively apply external power to the light-emitting layer, so that it does not cause a decrease in luminous brightness. Situation. The above-mentioned electrophoretic thin film forming systems are known by vacuum evaporation, sputtering, CVD, ion plate, spraying, etc. Depending on the type of the above materials and the necessary film thickness, appropriate conventional techniques can be used. method. In the case of a sputtering method, for example, a general sputtering method using a compound or a reactive sputtering method using a metal target can be used. At this time, oxygen, nitrogen, water vapor, etc. of the reactive gas are introduced, and means such as ozone addition and ion assist are used. At this time, a bias voltage such as DC, AC, or high frequency is applied to the substrate. The same applies to other preparation methods such as the vapor melting method and the CVD method. The film thickness of the electromotive substance film is preferably 1 to 300 nm. When the film thickness is less than 1 nm, the effect of suppressing the blackening of the transparent conductive film is insufficient. If it is larger than 300 nm, it has no effect on the optical design of improving the light transmittance of the transparent conductive film. An EL panel using the transparent conductive film of the present invention is produced by sequentially stacking a light-emitting layer, an electromotive substance layer, a planar electrode layer, and an insulating layer on a transparent conductive film of a transparent conductive film. For each layer, a dry process method such as a vapor deposition method or a sputtering method may be used, and a wet printing method may also be used. The printing method is preferred in terms of manufacturing cost. The light-emitting layer is one in which the light-emitting body powder is dispersed in an adhesive resin. The resin must be a tree with excellent moisture resistance in order to prevent the luminous body from moisture.

The fluorine-based elastomer is preferably a monomer or a copolymer of fluorinated ethylene, hexafluorinated propylene, ethylene tetrafluorinated ethylene, perchloromethyl vinyl ether, and the like. In addition, in order to enhance the adhesion to the transparent conductive film or the electro-attractor layer, polyester resin, acrylic resin, epoxy resin, melamine resin, methacrylic resin, urethane acrylic resin, and polysilicon can be mixed. Oxane resin, etc. It is preferred that the luminescent powder contains ZnS as the main component. The added light can select the emission wavelength in the visible light range. The added impurities are preferably selected from Cu, Ag, Cl, I, Al,. Mn, PrF3, NdF3, SmF3, EuF3, TbF3, DyF3, HoF3, ErF3, TmF3, YbF3, and the like. The luminous wavelength λE of these luminous body powders and the wavelength λ I with the highest light transmittance of the transparent conductive film of the present invention used for transparent electrodes can be provided. The design satisfies the following formula, and the electron emission has a very high luminous luminance. board. λ I -50nm ^ λ λ I + 50nm When the difference between λE and λΐ is greater than 50 nm, the effect of increasing the luminous brightness is insufficient. In order to improve the moisture resistance of the light-emitting powder, it is preferable to form a moisture-proof coating such as aluminum oxide, titanium oxide, silicon oxide, and magnesium oxide on the surface. Moreover, for 1 g of the adhesive resin of the light-emitting layer, the light-emitting body powder is preferably dispersed at a ratio of 0.1 to 100 g. If it is less than 0.1 g, the luminous brightness is not sufficient, and if it is more than 100 g, the adhesion effect by the adhesive is insufficient. The thickness of the light-emitting layer is preferably 1 to 100 // m. If the thickness is less than l # m, the luminous brightness is still insufficient, and if it is more than 100 / zm, it is not easy to use -30-513731. V. Description of the invention (29) It is not desirable for productivity to be printed in one process. In the same manner as the light-emitting layer, the electromotive substance layer is laminated on a fluorine-based elastomer to disperse powders having high electromotive power, such as titanium oxide, barium titanate, lead titanate, potassium niobate, and lithium tantalate. The thickness of the electromotive body layer is preferably 1 to 1 00 // m. If the thickness is less than 1 // m, the reflow current from the back electrode to the light-emitting layer is excessive, and the luminous brightness is reduced. If the thickness is larger than that, it is not easy to print in one process, which is not desirable in terms of productivity. The back electrode is printed by dispersing carbon and / or silver powder in a polyester resin. The thickness of the printed layer is preferably 1 to 100 # m. If the thickness is less than 1 // m, the surface resistivity of the back electrode is too high, and the luminous brightness is reduced. If the thickness is more than 100, it is not easy to print in one process, which is not desirable in terms of productivity. The surface resistivity of the back electrode is preferably 0.1 to 500 Ω / □. If it is less than 0.1 Ω / □, the thickness of the back electrode must be quite thick, which is not desirable in terms of productivity. If it is more than 500 Ω / □, it is impossible to effectively apply an external voltage to the light-emitting layer with a high surface resistivity, thereby reducing the luminous brightness. The insulation layer is made of polyester resin, acrylic resin, epoxy resin, melamine resin, methacrylic resin, urethane acrylic resin, polysiloxane resin, etc. as the main component with 1 ~ 1 00 # m. The printer is better. If the thickness is less than 1 # m, the insulation effect is not good. When the thickness is more than 100 μm, it is not easy to print in one process, and it is not desirable in terms of productivity. In addition, in the present invention, on the surface where the transparent conductive film is not formed with a transparent conductive film, in order to prevent scratches during the process of manufacturing the EL panel -31-513731 V.

The hard coating layer is used to crosslink a hardening resin such as a polyester resin, an acrylic resin, an epoxy resin, a melamine resin, a methacrylic resin, a urethane acrylic resin, or a polysiloxane resin, alone or in combination. Type resin hardened layer. The thickness of the hard coating treatment layer is preferably 3 to 50 // m, and more preferably 4 to 30 // m. If the thickness is less than 3 //, the function of hard coating treatment is not. If it is larger than 50 #m, the coating speed of the above-mentioned hardening resin-containing coating liquid on the transparent conductive film needs to be significantly slowed down, which is not desirable in terms of productivity. The method for laminating a hard-coating treatment layer is to apply the coating solution containing a hardening resin on the reverse side of a transparent conductive film provided with a transparent conductive film by a gravure method, a reversible method, a mold method, or the like. It is hardened by applying energy such as heating, ultraviolet rays, and electronic wires. The uneven surface treatment layer is formed by coating and drying a hardening resin, and then forming unevenness on the surface of the coating layer with an embossing roll, an embossed film, or the like, and then applying energy such as heat, ultraviolet rays, and electron rays to harden it. The hardening resin is a polyester resin, an acrylic resin, an epoxy resin, a melamine resin, a fluorene-based acrylic resin, a urethane acrylic resin, a polysiloxane resin, a polyimide-based resin, or the like, alone or in combination. Those are better. Or inorganic or / and organic fillers can be mixed in the resin. The anti-reflection treatment layer is a laminated single layer or two or more layers with a refractive index different from that of the biaxial -32- 513731. (31) Alignment PET film is preferred. In the case of a single-layer structure, a material having a lower refractive index than that of a biaxially oriented PET film can be used. In addition, in a multilayer structure of two or more layers, a material adjacent to the biaxially oriented PET film may use a material having a larger refractive index than the uniaxially oriented PET film, and a material having a lower refractive index than that of the layer may be selected on the layer. . The material constituting the anti-reflection treatment layer may be any organic material or inorganic material as long as it satisfies the above-mentioned refractive index relationship, and is not particularly limited. For example, CaF2, MgF2, NaAlF4, Si0, ThF4, Zr. 2, Nd203, SnO2, Ti02, Ce02, ZnS, ln203 and other electromotive substances are preferred. The method of laminating the anti-reflection treatment layer may be a dry coating process such as a vacuum evaporation method, a sputtering method, a CVD method, an ion plate method, or a wet method such as a gravure coating method, a reversible method, and a mold method Coating procedure.
