[Prior Art] In recent years, as a display device such as a television or a personal computer, a touch display device having a touch panel in front of a display device such as a liquid crystal display device or an electroluminescence (organic EL) has been used. Since the touch panel is provided with various types of thin films on the display elements, there is a problem that a clear ring or a dark ring stripe (hereinafter referred to as "Newton's ring") occurs due to interference of light. In order to prevent such problems, various countermeasures are proposed for the display device. One of the countermeasures is a method of roughening the surface of a hard coating film used for a display device. For example, in a hard coating agent for forming a hard coat layer, a crucible is mixed, and a hard coat layer is formed to a thickness that does not reach the particle size of the crucible, so that the crucible protrudes from the surface of the hard coat layer to roughen the surface thereof. The method (for example, refer to Patent Document 1).

These are caused by scattering of light in order to prevent the uneven shape of the surface of the hard coating layer caused by the protrusion of the Newton ring. Further, the method described in Patent Document 1 limits the film thickness range in order to prevent the Newton's ring. This is because, in order to impart a concavo-convex shape to the surface of the hard coat layer, it is necessary to have a film thickness that does not reach the particle size of the crucible.

Within the range of 〇. 1~1 〇 mass%. When the content of the component (B) is less than 0.01% by mass, the hardness of the resin layer containing particles of -13 to 201127627 may be insufficient. On the other hand, when it exceeds 20% by mass, the hardness of the resin layer containing the particles may be impaired. 1-3. (C) Inorganic Particles The curable composition of the present embodiment contains (C) inorganic particles. One of the functions of the component (C) is exemplified by the formation of an aggregate on the surface of the resin layer containing the particles to form a concavo-convex shape on the surface thereof, and to prevent uneven brightness or Newton's ring of the pixel. As the inorganic particles, cerium oxide particles, alumina particles, oxidized pin particles, or the like can be used. When the difference in refractive index between the inorganic particles and the resin component in the resin layer containing the particles is large, since the haze of the resin layer containing the particles is high, it is preferred to use a difference in refractive index between the inorganic particles and the resin component at 589 nm. 0.3 or less, preferably 0.1 or less particles. For these reasons, the inorganic particles are preferably cerium oxide particles. The cerium oxide particles are usually sold in a state in which cerium oxide particles are uniformly dispersed in a hydrophilic solvent such as water or alcohol. However, in the preparation of the curable composition of the present invention, since it is not preferable from the viewpoint of compatibility with water, it is preferred to disperse in a hydrophilic organic solvent such as an alcohol. Bismuth particles are usually made of water glass. These colloidal cerium oxide particles can be easily obtained from commercial products. Further, the colloidal cerium oxide particles having a hydrophilic organic solvent dispersibility can be easily prepared by replacing the water of the water-dispersible colloidal cerium oxide particles with a hydrophilic organic solvent. Further, these hydrophilic organic solvent-dispersible colloidal cerium oxide particles can be easily obtained from commercially available products. -14 - 201127627 (c) The average primary particle diameter of the inorganic particles is preferably from 5 to 200 nm, more preferably from 5 to 150 nm. (C) The average primary particle diameter of the inorganic particles can be determined by, for example, averaging 50 particle diameters measured by a transmission electron microscope. By making the average primary particle diameter within the above range, internal scattering of light in the resin layer containing particles can be reduced, so that haze can be reduced. When the average primary particle diameter is less than 5 nm, it is difficult to form a concave-convex shape on the surface of the resin layer containing particles, so that it is difficult to prevent uneven brightness of the pixels or Newton's rings. On the other hand, when the average primary particle diameter exceeds 200 nm, the internal dispersion of light in the resin layer containing particles becomes large, so that the transparency tends to be lowered. The content of the component (C) in the curable composition of the present embodiment is preferably in the range of 0.1 to 20% by mass, more preferably in the range of 0.1 to 20% by mass, based on the total of the components other than the organic solvent (E). Within the range of 1 to 15% by mass. When the content of the component (C) is less than 0.1% by mass, the transparency of the resin layer containing particles is excellent, but it is difficult to prevent pixel brightness unevenness or Newton's ring. On the other hand, when the content is more than 20% by mass, the internal scattering of light in the resin layer containing particles tends to be large, so that the transparency tends to be lowered. 1.4. (D) Particle aggregating agent The curable composition of the present embodiment contains (D) a particle aggregating agent. One of the functions of the component (D) is that when the resin layer containing particles is formed, the (C) inorganic particles are aggregated to form an aggregate. The (D) particle aggregating agent is preferably an amine compound or a salt thereof, or a quaternary ammonium salt. The amine compound can be suitably selected from, for example, an aliphatic amine, an alicyclic amine, an aromatic amine, and a heterocyclic amine. Further, the number of nitrogen atoms in the amine compound is not particularly limited to -15-201127627. As the quaternary ammonium salt, for example, any of a cationic surfactant and an amphoteric surfactant may be used, but it is more preferably a cationic surfactant. The cationic surfactant of the quaternary ammonium salt may be suitably selected from the compounds dissolved in an organic solvent.

When a cyclic olefin resin film is used as the transparent substrate layer 10, a melt molding method or a solution casting method (solvent casting method) can be used. In the conventional method, the cyclic olefin-based resin is formed into a film or a sheet. Among these, the solvent casting method is preferred in terms of uniformity of film thickness and surface smoothness. Further, in terms of the production cost, the melt molding method is preferred. The phase difference of the transparent substrate layer 1 is obtained.

Further, the standard deviation of the thickness per Um plane distance of the transparent substrate layer is usually preferably 10% or less, preferably 5% or less, more preferably 1% or less, still more preferably 0.5% or less. By performing the control of the thickness, unevenness in the plane of the conductive laminated film can be prevented. The transparent base material layer 1 may be a resin film which is subjected to elongation processing as needed when the touch panel is disposed in a liquid crystal display device. The resin film to be stretched can be produced by a conventional uniaxial stretching method or a biaxial stretching method. That is, a transverse uniaxial stretching method formed by a tenter method, a roll-to-roll compression stretching method, a longitudinal uniaxial stretching method using rolls having different outer diameters, or the like, or a combination of a transverse single axis and a longitudinal single axis may be used. The shaft extension method, the extension method by the expansion method, and the like. In the case of using a cyclic olefin resin film, the stretching speed in the uniaxial stretching method is usually from 1 to 5,000 % / min, preferably from 50 to 1, 000% / min, more preferably from 100 to 1,000 ° /. /min, better yet ~500%/min. In the case of the two-axis stretching method, there are cases in which the stretching is performed in two directions at the same time or in the direction in which the uniaxial stretching is performed in a direction different from the initial extending direction. In these cases, the angle of intersection of the two extension axes is usually in the range of 1 2 0 to 60 degrees. Further, the stretching speed may be the same or different in each extending direction, and is usually 1 to 5,000%/min, preferably 50 to 10! , 〇〇〇%/min, more preferably 100 to 1,000%/min' and more preferably 100 to 500%/min. -23- 201127627 The extension processing temperature is not particularly limited, but the transparent resin shift temperature (Tg) is used as a reference, and is usually Tg ± 30 ° C, preferably ° C, more preferably Tg - 5 to Tg + 10 ° C. range. Since the extension is within the above range, the occurrence of phase difference unevenness can be suppressed, and the refractive index ellipsoid can be preferably used. The stretching ratio is determined depending on the kind of the resin and the desired characteristics, but when the cyclic olefin-based polymer film is used, it is 1.01 to 10 times, preferably 1.1 to 5 times, more preferably 1.1 to 3.5 times, more than 1 time. There will be difficulty in controlling the phase difference. < The extended film can be directly cooled, but it can be allowed to stand at least for more than 10 seconds at Tg-20 °C to the atmosphere, preferably for 30 seconds to 60 minutes. 60 minutes. According to this, a phase difference film having a small phase difference characteristic and stability is obtained. In addition, the coefficient of linear expansion of the transparent substrate layer 1 is preferably less than 1 χ 1 〇 4 (W ° C ) in the range of temperature β 100 ° C, and is less than 5 ( l / ° c ), and more preferably 8xl0·5 (l/°c) or less, xl0_5 (1TC) or less.

It is preferably 7 and the extension 1/°C). The above phase is changed by using the time difference or the laminate is made by 0*5 (l/°c). -24 - 201127627 The extended film as described above can be aligned by the extension and impart a phase difference to the transmitted light, but the phase difference can be obtained by the phase difference 値 and the stretching ratio, the extension temperature, and the extended alignment of the film before stretching. The thickness of the film is controlled. Here, the phase difference is defined as the product of the refractive index difference (A η ) of the birefringent light and the thickness (d ) (Δ nd ).

When a cyclic olefin resin film is used The corona treatment condition is preferably 1 to 1,0 0 OW/m 2 /min as the irradiation amount of the corona discharge electrons, more preferably 10 to 100 W/m 2 /min. Below the irradiation amount, there may be no When the surface modification effect is obtained, when it is higher than the irradiation amount, there is a treatment effect and the inside of the transparent substrate layer 10, and the film itself is deteriorated. The corona treatment not only protects the particles from the particles. The layer 20 may be applied to the surface on which it is abutted, or may be applied to the surface on the opposite side. Alternatively, it may be applied immediately after application of corona treatment, or may be applied after self-elimination, thereby changing the appearance of the protective layer containing particles. From a good point of view, it is preferred to apply it after de-energization. 2.1.2. Resin layer containing particles - 25, 276, 276 A resin-containing layer 20 containing particles is formed on one side of the above-mentioned transparent substrate layer ι. The resin layer 20 contains an aggregate of inorganic particles. The resin layer 20 containing particles can have an uneven shape on the surface thereof by an aggregate containing inorganic particles, whereby excellent anti-Newtonian properties can be formed without pixel brightness. A heterogeneous resin layer containing particles. The average primary particle diameter of the inorganic particles is preferably from 5 to 200 nm, more preferably from 5 to 150 nm, and the average primary particle diameter can be obtained by, for example, an average of 50 particle diameters measured by a transmission electron microscope. When the primary particle diameter falls within the above range, the internal scattering of light in the resin layer containing the particles can be reduced, so that the haze of the electroconductive laminate can be reduced. When the average primary particle diameter is less than 5 nm, it is difficult to contain particles. Since the uneven shape is formed on the surface of the resin layer, it is difficult to prevent uneven brightness of the pixel and the Newton's ring. On the other hand, when the average particle diameter exceeds 200 nm, the internal scattering of light in the resin layer containing the particles becomes large, so that the conductive layer is provided. The tendency of the transparency of the fit to decrease. The aggregate content of the inorganic particles in the resin layer 20 containing particles is preferably in the range of 0.1 to 20% by mass, more preferably 1 to 10% by mass. When the content of the inorganic particles is less than 0.1% by mass, the resin layer is excellent in transparency, but it is difficult to prevent pixel brightness unevenness and Newton's ring. On the other hand, when it exceeds 20% by mass, the internal scattering of light in the resin layer becomes large, and the transparency tends to be lowered. The resin layer 20 containing particles can be formed using a curable composition containing inorganic particles. A preferred specific example of the curable composition is a curable composition described in the section "1. Curable composition". The thickness of the resin-containing resin layer 20 is preferably from 0.5 to 20 μm, more preferably from -26 to 201127627, and from 1 to 15 μm, preferably from 2 to ΙΟμπι. Hereinafter, a method of forming the resin-containing resin layer 20 will be described. First, a curable composition containing inorganic particles is applied to one surface of the transparent substrate layer 10 to form a coating layer, which is dried. The coating method is not particularly limited, and for example, bar coating, air knife coating, gravure coating, reverse gravure coating, reverse roll coating, film lip coating, die coating, dip coating, lithography can be used. Conventional methods such as soft board printing and screen printing. The thickness of the coating layer can be controlled by calculating the solid content concentration contained in the curable composition and the density of the resin-containing resin layer 20 after curing, and calculating the coating amount of the curable composition. After coating, the organic solvent contained in the curable composition is volatilized by drying. According to this, the aggregation of the inorganic particles can be further promoted. The drying treatment is preferably carried out at a temperature of 50 to 120 ° C for about 0.5 to 4.0 minutes. The longer the drying time, the easier it is to move the inorganic particles and promote their aggregation. Then, the dried coating layer is irradiated with ultraviolet rays to be hardened, and the aggregate of the inorganic particles can be fixed to the surface or inside of the resin-containing resin layer 20. The ultraviolet irradiation device is not particularly limited, and a conventional high-pressure mercury lamp, a xenon lamp, a metal halide lamp, a fusion xenon lamp, or the like can be used. The amount of ultraviolet radiation is usually about 300 to 800 mJ/cm2. As described above, by using a method of forming an aggregate of inorganic particles as a method for imparting anti-Newtonian ring properties, the shape, film thickness, and interval of the resin layer containing particles can be precisely controlled, and transparency and anti-Newtonian ring properties can be obtained. , and there is no good resin layer with uneven pixel brightness. -27- 201127627 The uneven structure of the surface of the resin layer containing particles formed by the aggregate of inorganic particles also prevents the Newton's ring from being formed by forming a concave-convex structure on the outer surface of the transparent conductive layer of the film. Moreover, since the uneven structure of the surface of the particle-containing resin layer formed by the aggregate of the inorganic particles does not largely change depending on the film thickness, it can be prevented in a wide range of film thickness compared with the conventional anti-glare film. Newton ring. Further, the conductive laminate 100 may be provided with an anchor coat and an antireflection layer between the transparent base material layer 10 and the resin layer 20 containing the particles. According to this, the conductive laminate 100 having excellent gas barrier properties and adhesion and improved transparency in the visible light region is obtained. 2.1. 3.

The thickness of the transparent conductive layer 30 is preferably from 30 to 3,000 angstroms, more preferably from 50 to 2,000 angstroms. When the surface resistance is less than 30 angstroms, the surface resistance becomes 1, 〇〇〇 Ω / □ or less, so that it is difficult to form a continuous film having good conductivity. On the other hand, when it exceeds 3,000 angstroms, the surface unevenness of the resin layer containing particles does not easily affect the uneven structure of the outer surface of the transparent conductive layer, so that it is difficult to effectively prevent the Newton's ring, and the transparency may be lowered. . The transparent conductive layer 30 is a layer obtained by dispersing an indium oxide containing tin oxide, indium oxide containing titanium oxide, tin oxide, titanium oxide, polythiophene, inorganic nanoparticles, or the like into an inorganic/organic composite tantalum material.

When it is Tg or more, the resin film is deteriorated. Further, a small amount of oxygen is introduced into the argon gas of the atmosphere gas at the time of film formation of ITO, and the volume of the mixed gas of argon gas and oxygen gas is preferably 0.05 to 20% by volume, more preferably 0 to 01 to 10 times. %, and more preferably 0.1 to 3 volume% of oxygen, the transparency and conductivity of the IT 0 film can be made good. As a method of forming the transparent conductive layer 30, any of the conventional techniques such as a vacuum deposition method, a sputtering method, and an ion plating method can be used, but the uniformity of the film and the adhesion of the film to the transparent substrate are considered. In other words, it is preferred to form a film by sputtering. Further, in addition to the above, a film material such as tin oxide containing antimony or the like may be used, and gold, silver, rhodium, palladium, copper, aluminum, nickel, chromium, titanium, cobalt, tin or the like may be used.
