Field of the Invention The present invention relates to a transparent coated film and an antireflection film using the same, and more particularly to a surface protective film suitable for use as a liquid crystal display, a plasma display or the like. A film is coated and an antireflection film using the coated film. [Prior Art] A coating film coated with a hard coat layer is used for the purpose of surface protection or antireflection of various display bodies of various optical lenses, cover covers, window glass, or liquid crystal displays, plasma displays, and the like. . However, in the coated film, the reflected light on the surface of the hard coat layer and the reflected light from the interface between the hard coat layer and the film substrate interfere with each other to generate an interference color, and if there is a spot on the coated thickness portion of the hard coat layer, There is a problem that the interference color further produces a pattern called "spot", which reduces the visibility. Here, in order to improve the color unevenness, a technique of lowering the refractive index of the hard coat layer and the substrate has been reported (for example, refer to Patent Documents 1 to 3). (Patent Document 1) Japanese Patent Laid-Open No. 0 7 - 5 6 0 0 2 (Patent Document 2) Japanese Patent Laid-Open No. 0 7 - 1 5 1 9 0 2 (Patent Document 3) Japanese Patent Special Open No. 0 8 - 1 7 9 1 2 3 [Invention] [Problems to be Solved by the Invention] 5 326V total file \93\93105517\93105517 (replacement)-1 1251678 However, the technique described in the above Patent Document 1 In this case, the refractive index of the hard coat layer and the plastic substrate can be changed substantially continuously in the thickness direction to cancel the color spot. However, since the hard coat layer is formed by the CVD method, it is unsatisfactory in terms of productivity and cost. Disadvantages. Moreover, in the case of the technique described in the above Patent Document 2, the metal oxide ultrafine particles are added to the coating film so as to reduce the difference in refractive index between the coating film which becomes the hard coat layer and the base film. For this reason, the ultrafine particles scatter light to generate a haze, and the total light transmittance is lowered. Therefore, there is a drawback that a film having a low haze and a high transmission vividness cannot be obtained. On the other hand, in the technique described in Patent Document 3, a coating film having a refractive index close to the refractive index of the film substrate is formed on the surface of the film substrate. However, in the case of a coated film used for a liquid crystal display, a plasma display or the like, a cellulose ester having no optical anisotropy is often used as a film substrate because a coating having a refractive index close to that of the film substrate is selected. Difficulties, there is a disadvantage that the film substrate that can be used is limited. Further, in order to solve the thickness spot which is the cause of the stain, conventionally, the precision of the coating head, the adjustment of the coating grade, and the adjustment of the film tension during coating have been performed. However, the accuracy of the coating head is limited, and even if the coating grade or the film tension is adjusted, a film having poor flatness (large surface unevenness) produced by a casting method, for example, a film of triacetyl cellulose or the like is used. In the case of a cellulose ester film, there is a disadvantage that it is not easy to remove the thickness spot. In such a conventional technique, in order to add a fine particle to a coating film to a refractive index base film, the haze is high and the transmission brightness is lowered, or 6 326 \ total file \93\93105517\93105517 can be used ( Replacement) -1 1251678 The film substrate or hard coat is limited. Accordingly, an object of the present invention is to provide a coated film having high transmittance due to interference even in the case of a film substrate or a hard coat layer, and an antireflection film using the same. (Means for Solving the Problem) In order to solve the above-mentioned disadvantages, the inventors of the present invention have variously reviewed the coating film composed of a hard coat layer on a film substrate, and the surface of the substrate is dissolved or swollen to make the hard coat layer and the film substrate. It can prevent the stain caused by interference. Then, if it is not necessary to add fine particles to the hard coat layer, a film having a high fog transmission efficiency can be obtained, thereby completing the present invention. Therefore, the present invention is a coating film formed by coating a coating layer of a transparent resin film substrate to which an organic solvent and a resin composition are mainly composed, and characterized in that the above-mentioned organic solution or swelling of the above resin film The surface of the substrate. The coated film of the present invention can attain high transmission vividness especially in the case where J I S - K 7 1 0 5 is 0.1 to 3%. In the case where the resin composition is a thermosetting resin composition curable resin composition or the resin film base ester film, and the organic solvent is a polymer having a molecular weight of 100 or less or an ester organic solvent, In particular, in the case where the difference between the refractive index of the coating layer and the resin film ratio is 0.01 or more, the above aspect of the present invention can be effectively prevented. Film coating 326\total file\93\93105517\93105517 (replacement)-1 With all kinds of thin spots, at the same time, the result is that the film-based interface is integrated, because the degree is low and there is less single-sided, coating The haze or ultraviolet light which is soluble in a transparent solvent is a cellulose ketone organic soluble L·stain. Refractive spot of the matrix. On the cladding layer, by using a layer having a refractive index lower than that of the coating layer by 71251678, it is possible to achieve an antireflection film having a refractive index difference of 0.001 or more. [Embodiment] Hereinafter, the present invention will be specifically described. The coated film of the present invention has a feature of forming a transparent coating layer on at least one side of a transparent resin film substrate, by coating a coating material containing an organic solvent and a resin composition as described below as a main component. In this case, the organic solvent dissolves or swells the surface of the resin film substrate, and integrates the interface between the coating layer and the resin film substrate. Therefore, it is considered that the color unevenness caused by the interference can be prevented. The resin film substrate of the present invention may be any resin film which is transparent as long as it is, for example, a triacetone cellulose film, a diethylcellulose film, a butyl cellulose film, a polyethersulfone film, or a polypropylene may be used. Phytosanitary film, polyamino phthalate resin film, polyester film, polycarbonate film, polysulfone film, polyether film, triterpene terpene film, polyether ketone film, (fluorenyl) Acrylonitrile film and the like. In particular, since triacetyl cellulose film and one-axis stretch polyester have excellent transparency and no optical anisotropy, they are suitable for use. The thickness of the film is usually preferably from 8 to 1 0 0 // m. The above coating material is mainly composed of an organic solvent and a resin composition, and the organic solvent used herein is required to dissolve or swell the surface of the resin film substrate. Here, the dissolving or swelling means that the composition of the surface of the resin film substrate can be dissolved in the organic solvent by applying a coating to the resin film substrate, and the coating is analyzed by X-ray analysis or infrared analysis. In the case of the layer, the above-mentioned dissolved component can be detected from the coating layer. 8 326\总档\93\93105517\93105517 (replacement)-1 1251678 When the cross section of the coating layer and the resin film substrate obtained by coating the coating is observed by an electron microscope or the like, an organic solvent in which the resin film substrate is not dissolved is used. In the case of the above, the above interface can be clearly confirmed, but in the case of the present invention, the interface becomes unclear or disappears. This is considered to be because the coating layer and the resin film substrate are integrated in such a manner that the refractive index difference between the two is continuously changed without being steep, so that the stain due to interference can be prevented. From this point of view, in the present invention, since it is not necessary to select a coating having a small difference in refractive index between the coating layer and the resin film substrate, or to add fine particles to the coating layer, it is possible to select various films. As the substrate, a coated film having low haze and high transmission vividness can also be obtained. In particular, the cellulose ester film such as the above-mentioned triacetyl cellulose film is produced by a laundering method, and its flatness is poor, and the surface unevenness is large. Therefore, the coating layer formed thereon is likely to have a thickness spot. Therefore, it is also easy to produce stains, so it is preferable to eliminate the thickness spots, but it is technically difficult to eliminate the thickness spots themselves. However, in the case of the present invention, since the refractive index change of both the interface between the coating layer and the resin film substrate is not steep but continuous, as described above, the color unevenness can be prevented even if the thickness spot is not eliminated. The organic solvent to be used in the present invention is not particularly limited, and for example, a known solvent such as a ketone organic solvent, an ester organic solvent, an aromatic compound, an alcohol or a solvent can be used. In particular, when the resin film substrate is a cellulose ester film such as a triacetyl cellulose film, it is preferable to use a ketone organic solvent or an ester organic solvent, and in particular, a ketone system having a molecular weight of 1,000 or less can be used. Organic solvent or / and ester organic solvent. If the molecular weight of the above-mentioned molecular weight setting 326\total file\93\93] 05517\93105517 (replacement) > 1 1251678 is 1 Ο 0 or less, the effect of dissolving the surface of the cellulose ester film is large. Examples of the ketone having a molecular weight of less than 100 include acetone, acetophenone, decyl-η-acetone, diethyl ketone, and cyclohexanone. Examples of the ester having a molecular weight of less than 100 include a mercapto acetate group, an ethyl acetate group, and a mercapto propionate group. In this case, the organic solvent is preferably cycloethyl ketone and ethyl acetate. Further, when the resin film substrate is the cellulose ester film, the ketone organic solvent or/and the ester organic solvent having a molecular weight of 100 or less is preferably 50% by weight or more, and most preferably the entire organic solvent. It is 60% by weight or more. If it is less than 50% by weight, the dissolution or swelling of the resin film substrate becomes insufficient, and the effect of preventing the stain due to interference is not easily obtained. However, if the ratio of the ketone-based organic solvent or the ester-based organic solvent is too large, since the resin film substrate is dissolved or swollen by the transition, the resin film substrate becomes opaque or the material eluted from the surface of the resin film substrate is mixed and coated. The layer is reduced in hardness. Here, the hardness of the coating layer is referred to as the degree of hardness of the coating layer, and the hardness is good means that it is wiped by a hard object such as steel wool, and it is not easy to cause scratches on the surface of the coating layer. Therefore, it is generally preferred that the ratio of the ketone organic solvent or the ester organic solvent in the organic solvent is 80% by weight or less, but the ratio of the organic solvent in the coating is reduced as compared with the resin composition. In the method of increasing the solid content concentration of the coating material, etc., if the degree of dissolution of the resin film substrate to the organic solvent is adjusted, the ratio of the ketone organic solvent or the ester organic solvent in the organic solvent is preferably 80% by weight or more. . The ratio of the organic solvent of the coating used in the present invention is preferably from 3 5 to 60 % by weight. If the concentration of the organic solvent is less than 35 % by weight, then the resin film substrate 10 326 \ total file \93\93105517\93105517 (replace; the dissolution or swelling of l·1 1251678 becomes insufficient, and it is difficult to obtain the color caused by the interference prevention. On the other hand, if the concentration of the organic solvent in the coating exceeds 60% by weight, since the resin film substrate is dissolved or swollen, the resin film substrate becomes opaque or the substance eluted from the surface of the resin film substrate is mixed. The coating layer is coated to reduce the hardness of the coating layer. The resin composition for the coating used in the present invention may be transparent, and the thermoplastic resin, the thermosetting resin, and the free radiation may be used singly or in combination. A curable resin, etc. In particular, in order to impart hardness to the coating layer, it is preferred to use a curing resin, and it is more preferable to use a free light-radiating curable resin composition which does not require heat during curing. The resin composition is cured by irradiation with an electron beam or ultraviolet rays, and the refractive index after curing is good as long as the solubility in the organic solvent is good. Any of them can be used as the composition of the free radical curable resin, and can be suitably selected from the group consisting of amino phthalate acrylate resin, polyester acrylate resin, and epoxy acrylate resin, and the like. Preferably, it is composed of an ultraviolet curable polyfunctional acrylate having two or more (fluorenyl) acrylonitrile groups in the molecule. Specific examples of the polyfunctional acrylate include (fluorenyl) Neopentyl glycol diacrylate, (methyl)-1,6-hexanediol diacrylate, (mercapto) tri-propyl propyl propyl triacrylate, (methyl) bis-three warp Polypropylene polyacrylic acid such as propyl acrylate, (mercapto) pentaerythritol tetrapropyl acrylate, (mercapto) pentaerythritol triacrylate, (meth) dipentaerythritol hexaacrylate, etc. A diglycidyl diacetic acid vinegar, neopentyl glycol diglycidyl ether diacrylate, (mercapto)-1,6-hexanediol 11 326\total file\93\93105517\93105517 (replacement)-1 1251678 epoxide of diglycidyl ether A mercapto acrylate, a polyester (meth) acrylate obtainable by esterifying a polyvalent alcohol with polyvalent carbonic acid and/or an anhydride thereof and acrylate, by making a polyvalent alcohol, a polyvalent isocyanate An amino phthalate propyl acrylate obtained by reacting an acid salt with a hydroxyl acrylate, a polyoxylated polyoxy acrylate, etc. The above ultraviolet ray curable polyfunctional acrylate may be used alone or in combination. When two or more types are used, all of the resin compositions used for the coating material may be used as the polymerizable acrylic acid S. In particular, it is preferable to set the ratio of the polymerizable acrylate to 95 to 50% by weight. In addition to the polyfunctional acrylic acid S, 2-hydroxy(indenyl)acrylate or 2-hydroxypropionyl (meth) acrylate may be added in an amount of 10% by weight or less of the entire resin composition. A monofunctional acrylate such as glycidyl (mercapto) acrylate. Further, as a purpose of adjusting the hardness of the coating layer, a polymerizable oligomer can be added to the coating material. Examples of such a polymerizable oligomer include terminal methacrylate polyacrylate, terminal styryl polyacrylic acid 6, terminal methacrylate polystyrene, and terminal mercaptopropionic acid. Macromonomers such as ester polyethylene glycol, terminal mercapto acrylate acrylonitrile/styrene copolymer, terminal mercapto acrylate styrene/methyl methacrylate copolymer. The content ratio of the polymerizable oligomer is preferably from 5 to 50% by weight based on the entire resin composition. Further, as a coating for pressure-proof bonding or the like, fine particles can be added to the coating material. However, when the fine particles are excessively added, the haze described later becomes high and the color spots become inconspicuous, but the transmittance and the transmission sharpness are lowered. Therefore, it is preferable to limit the amount of the fine particles to be added so that the haze does not become high. Moreover, the crimping means that when the coating film of the 12 326\total file \93\93105517\93105517 (replacement)-1 1251678 is formed into a take-up roll shape, the coating layer and the base film adhere to each other, in part When a roller that is crimped is produced, if the winding is loose or wound, or if it is expanded or contracted by the storage temperature, the film is deformed when the roller is released. The fine particles are not particularly limited as long as they can be dispersed on the coating material. For example, an organic or inorganic pigment can be used. Specifically, in addition to inorganic pigments such as cerium oxide, oxidized oxidized, and oxidized, etc., examples thereof include a propylene baking resin, a polyphenylene baking resin, a polyvinyl chloride resin, a polycarbonate resin, a Μ Μ A resin, and a stone. A polymer glass bead such as a resin or a polyurea resin. Further, in the range which does not impair the effects of the present invention, an antifoaming agent, a leveling agent, a rocking agent, a tackifier, a particle dispersing agent, a generation preventing agent, an oxidation preventing agent, and an ultraviolet absorber may be contained in the coating material. , light stabilizer, polymerization inhibitor, etc. A defoaming agent, a rocking agent, a tackifier or the like may be added in the case where the solid content concentration in the coating material is low and the applied liquid film produces a large thickness spot during drying and has a suspense of color spots. As the coating material adjusted as described above, a coating device such as a micro gravure coater, a gravure coater, a precision bar coater, a composite coater, or the like can be used. The coating amount may be adjusted so that the dried coating layer is about 2 to 12 g / m 2 . The coating layer can be formed by drying the coated coating or hardening the cured resin. The haze of the coated film thus produced is preferably from 0.1 to 3%, especially preferably from 0.1 to 1%, as measured according to J I S _ K 7 1 0 5 . When the haze exceeds 3%, the transmittance of the coated film is lowered, and a coating film having high transmission and vividness cannot be obtained. On the other hand, the lower limit of the haze of 13 326\total file \93\93105517\93105517 (replacement)-1 1251678 is set to less than 0.1%, because the haze of the resin film substrate is about 0.1%. Difficulties. In the coated film of the present invention, even if the difference between the refractive index of the coating layer and the refractive index of the resin film substrate is Ο 13 3 or more, the characteristics of the stain can be effectively prevented. That is, in the prior art, the difference in refractive index between the hard coat layer and the substrate is reduced and interference is not easily generated, thereby suppressing the color unevenness. In this case, according to the above-mentioned Patent Document 2', when the refractive index difference between the two is 0. 0 0 or more, color spots are generated. Actually, it has been found from the review by the inventors of the present invention that when the refractive index difference between the two is Ο 3 1 3 or more, significant color spots are generated. However, the case of the present invention suppresses the stain by a method of dissolving the surface of the resin film substrate and substantially eliminating the interface between the coating layer and the resin film substrate by a completely different principle from the above-described conventional technique, and thus no adjustment coating is applied. The difference in refractive index between the layer and the resin film substrate is necessary, so that even if the refractive index difference between the two is Ο 3 1 3 or more. Thereby, the degree of freedom in the selection of the film substrate or the coating layer can be increased. Further, a low refractive index layer may be further provided on the coating layer of the coated film of the present invention to constitute an antireflection film. In this case, in order to impart antireflection energy, it is necessary to set the refractive index of the low refractive index layer to be lower than the refractive index of the coating layer, and to set the difference to be 0.01 or more. It is also possible to provide a high refractive index layer on the coating layer and a low refractive index layer on the surface of the high refractive index layer, but in this case, the refractive index of the low refractive index layer and the refractive index of the high refractive index layer are still The difference is set to 0. 0 1 or more. As a material for forming the low refractive index layer, an organic ruthenium compound, a fluorine compound, a boron compound or the like can be used. As a material for forming the high refractive index layer, a titanium oxide such as titanium oxide or an alkoxy 14 326, a total of \93\93105517\93105517 (replacement)-1 1251678 base titanium, a high refractive index metal oxide fine particle and Resin mixer, etc. (Examples) Hereinafter, the present invention will be described in more detail by way of Examples and Comparative Examples, but the invention is not limited thereto. In addition, unless otherwise specified, the "parts" and "%" listed below indicate "weight" and "% by weight", respectively. 1. Preparation of Coating Material Using the resin composition shown in Table 1, an organic solvent, and other additives, each of the examples and the comparative examples was prepared into a coating material having a different composition. In the resin composition, a UV-curable resin Η 601 (a main component of a pentaerythritol monomer, a trade name of Sanyo Chemical Co., Ltd.) was used, and in addition to the above organic solvent, the liquid was added in a portion of 0 to 0. 0 The ratio of 5 parts is matched with the leveling agent BY Κ - 3 0 0 (trade name of BIC Chemical Co., Ltd.). Further, in the case of Comparative Examples 8 and 9, the cerium oxide fine particles having a particle diameter of 1.6 and 1.5 mM were mixed in the coating material. The mixing ratio of the resin composition, the organic solvent, and the fine particles is shown in Table 1. Also, the IPA in the table is isopropanol. 2. Preparation of coated film The above coating was applied to one surface of the film substrate shown in Table 1 using a precision rod. After the application, the diluted solvent in the coating was evaporated by a dryer at 60 ° C, and the resin was cured by irradiation with UV light to form a coating layer. The thickness of the coating layer was 6 / / m. Further, in Table 1, a TAC-based triacetonitrile cellulose film having a thickness of 80 μm (trade name: FT-8O UZ: Fujifilm) was used, and AC was propylene having a thickness of 1.25 μm.

First, a precision rod is used on one side of the above TAC to separate the components. The coating was applied in the same ratio as the upper side of "/" in Table 1, and a coating film was produced in the same manner as in the respective examples. The thickness of the coating layer at this time was 3 // m, and the surface roughness Ra was 0. 3 5 / m. On the surface of the coating layer, a coating material was applied at a mixing ratio in which the respective components were set to the lower side of "/" in Table 1, and a coating film was produced in the same manner as in the respective examples. The thickness of the second coating layer was 3 // m, and the coating thickness of the coating layer of the two layers was 6 / / m. Further, on the coating layer of the coating film of Example 1, the alkane was blended. Hydroxy citrate 1 0 0 (L 1 0 0 1 : manufactured by Seiko Chemical Co., Ltd.) and ethanol 300 (manufactured by Kanto Chemical Co., Ltd.), adjusted to a solid concentration by precision rod coating The anti-reflective film was obtained by drying with a blowing desiccant at 6 (TC, 1 minute) to form a low refractive index layer having a film thickness of 110 nm. This is taken as an example 16. The average regular reflectance (wavelength: 4 0 0 to 70 nm) of the obtained antireflection film is 3% or less because the lower refractive index layer is less than that of the first embodiment. The average positive reflectance of the coated film is 5.6 %, so that the antireflection film has a sufficient antireflection effect. Further, the reflectance is measured by a spectrophotometer (U - 3 3 1 0 by Hitachi, Ltd.). 16 326\总档\93\93105 517\93 ] 05517 (replacement)-1 1251678 [Table 1] Film base organic solvent 1 Weight part organic solvent 2 Weight part resin composition (weight part) Microparticle (weight part) Example 1 TAC toluene 9 cyclohexanone 36 55 - Example 2 TAC toluene 9 Ethyl ketone 36 55 - Example 3 TAC toluene 9 Acetic acid ethyl 36 55 - Example 4 TAC toluene 9 propionate decyl group 36 55 - Example 5 TAC IPA 9 cyclohexanone 36 55 - Example 6 TAC ethyl cellosolve 9 cyclohexanone 36 55 - Example 7 TAC IPA 9 Acetate ethyl 36 55 - Example 8 TAC Ethyl Solution Fibril 9 Acetate Ethyl 36 55 - Example 9 TAC - - Ethyl Ethyl Ketone 45 55 - Example 10 TAC - —ethyl acetate 45 55 — Example 11 TAC toluene 22.5 cyclohexanone 22. 5 55 — Example 12 TAC toluene 7 cycloethyl ketone 28 65 — Example 13 TAC toluene 12 Cycloethyl ketone 48 40 — Example 14 TAC toluene 13 Cycloethyl ketone 52 35 - Example 15 AC Benzene 9 Cycloethyl ketone 36 55 - Comparative Example 1 TAC Benzene 9 Hydrylisobutyl ketone 36 55 - Comparative Example 2 TAC Benzene 9 Acetic Acid Isopropanol 36 55 - Comparative Example 3 TAC toluene 27 cyclohexanone 18 55 - Comparative Example 4 TAC toluene 36 cyclohexanone 9 55 - Comparative Example 5 TAC toluene 45 - 55 - Comparative Example 6 TAC toluene 6 Cyclohexane ketone 24 70 - Comparative Example 7 PE Benzene 9 Cycloethyl ketone 36 55 - Comparative Example 8 TAC Benzene 9 Cycloethyl ketone 36 55 5 Comparative Example 9 TAC Benzene 9 Hydrylisobutyl ketone 36 48/55 7 /0 3 . Evaluation (1) State of the interface A cross-sectional photograph of each of the coated films was photographed by a scanning electron microscope, and the interface between the coating layer and the resin film substrate was clearly observed as (the film substrate was) "undissolved" When the interface is not clear, it is evaluated as "dissolved". (2) Color spot The surface of the non-coated side of the coated film was wiped by steel wool, and the surface was colored by a black spray paint to be completely dried. The coated film was visually observed from the side of the coated surface under a 3-wavelength type fluorescent lamp in a dark room, and the color spot at this time was evaluated. 17 326\总档\93\93105517\93 ] 055 ] 7 (replace)-1 1251678 〇: no color plaque △: slightly colored spots X: obvious spots XX: most noticeable spots (3) scratch resistance On the surface of the coating layer coated with the film, a steel wool of 8000 g of weight #0 0 0 was placed, and the surface of the coating layer was wiped by moving the steel wool to visually judge the degree of the occurrence of the flaw. 〇: no scratch △: slightly scratched X: scratched clearly (4) haze The haze of the coated film was measured according to J I S - K 7 1 0 5 .

This confirms the excellent performance through the excellent image. Further, in Example 14, the ratio of the organic solvent was 65 wt%, and although the scratch resistance was lowered, the anti-staining and haze which were able to achieve the object of the invention were lowered. Further, in each of the examples, the dissolution of the resin film substrate was confirmed at any of the interfaces. On the other hand, in the case of Comparative Examples 1 and 2, since the organic solvent system uses decyl isobutyl ketone and isopropyl alcohol acetate in place of cyclohexanone, the resin film substrate of the interface is not dissolved, and color resistance cannot be obtained.

In particular, in the case of Comparative Example 5 in which cyclohexanone was not blended, the effect of preventing color spots was confirmed to be the worst. In the case of Comparative Example 6, since organic The ratio of the solvent was 30% by weight and was low, so that the resin film substrate at the interface was not dissolved, and the effect of preventing the color unevenness was not obtained. In the case of Comparative Example 7, although the acryl film was used as the resin film substrate, the coating was Since the selection of the organic solvent is not appropriate, the resin film substrate of the interface is not dissolved, and the effect of preventing the color unevenness cannot be obtained. In the case of Comparative Examples 8 and 9, since the fine particles are added to the coating layer, the effect of the anti-staining effect is obtained. Good, but since the haze is more than 3%, the transmittance or the transparency of the film is lowered. Further, in each of the embodiments of the present invention, the ratio of the ketone-S is 50 to 100% by weight. Scope, again, in addition to implementation In addition, the ratio of the organic solvent is in the range of 3 5 to 60% by weight. From such a case, it is apparent that the ratio of the ketone-S is preferably set to 50 to 100% by weight, and further, organic The ratio of the solvent is set to 3 5 to 60% by weight. (Effect of the Invention) In the present invention, since the organic solvent in the coating dissolves or swells the surface of the film substrate, color unevenness due to interference can be prevented, and at the same time, Transmissive film with high transmittance and high transparency. 20 326\总档\93\93105517\93105517 (replacement)-1
