[Technical Field] The present invention relates to a transparent conductive sheet in which a conductive fine line of a high-definition pattern is formed on a transparent support, and a conductive thin line for forming a high-definition pattern is formed. Photosensitive material of transparent conductive sheet, manufacturing method of transparent conductive sheet, and capacitive touch panel using the transparent conductive sheet 0 [Prior Art] In the field of touch panel, projection type capacitive touch The panel is being widely used for a Personal Digital Assistant (PDA) or a mobile phone, and has begun to try to increase the size of the touch panel. In the case of increasing the size of the panel, the transparent electrode must have a low resistance. As a technique for reducing the resistance, for example, Patent Document 1 and Patent Document 2 describe a sensing portion in which a capacitance is formed by a mesh-shaped conductive thin wire. Methods. The method of forming the mesh-like conductive thin wires described in these documents is a printing method of a conductive ink, or a thinning of indium tin oxide (ITO) or a metal thin film by photolithography, but In the printing method of the former, there is a problem that it is difficult to stably form a thin line having a line width of 2 μm or less. In the latter, there is a problem that the photolithography step includes a plurality of steps and the cost is high. On the other hand, in the field of an electromagnetic wave shielding film or a printed wiring, a method of controlling a thin wire of a low-resistance silver image by a self-chemical silver-light-reducing material is being studied. The age-type _ (four) mask exposure and subsequent processing to form various patterns, the manufacturing steps are stable 4 201234140. For example, Patent Document 3 discloses an example in which a mesh pattern having a fine line width of 20 μm and a lattice interval of 250 μm and a surface resistance of 50 Ώ/□ to 1 □ □ is described. In the method of producing the capacitance sensing portion by using the conductive thin wires, when the first electrode and the second electrode shown in FIG. 7 of Patent Document 1 are laminated to form a touch panel, it is necessary to be on the self-toucher side. When the panel is seen through, it is laminated in a uniform mesh shape as shown in FIG. If it does not have a uniform mesh shape and uneven overlap or blank is generated, it becomes a defect that the kneading surface looks uneven and the visibility is poor. Therefore, the alignment of the two conductive sheets requires high precision, which results in high-precision alignment in each touch panel, and there is a problem that the productivity of the touch panel is poor. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Laid-Open No. 2010-039537 (Patent Document 2) International Publication No. 2/〇丨4683 [Patent Document 3] Japanese Patent Application In the recent years, in order to make the sheets of the two conductive sheets bonded together, the table and the back _ == method of the transparent sheet are tried. The conductive H: the electrode formed on both sides of the front and back sides of the transparent slab body is required to be a uniform pattern as shown in FIG. 8 of Patent Document i. It is generally considered that the photosensitive material is used as the electrode forming material y for exposure and next to it. After the development process to form the electrode, however, it is known that the front and back sides of the transparent support form a contrast of the case where the surface of the 20124140 surface and the fluoroscopic image of the electrode become a uniform pattern, and a subtle color is also produced. The method of using two silver or the hue of the surface varies depending on the conditions for forming the electrode: in the case of 幵 ==). It is inferred that the phenomenon is as follows == K, that is, when a relatively thick electrode film is formed, = the fineness of the metal film in the film which has become a thick film == 提#本^5 The object of the invention is to produce a transparent conductive sheet having a hue of "==::r, which includes an electrode for developing silver". Further, the present invention provides a color tone for the control electrode of the large book, and a low resistance, which can be used for the transparent electrode of the panel. In addition, in the other eye-control panel of the present invention, the above-mentioned contact person who has improved the St-tone of i has intensively investigated the cause of the unevenness of the color tone, and the result was completed based on the following facts. invention. Electrode: the transparent cover of the sheet (4) is formed with the first panel on both sides of the front and back sides. The core 1 is turned on and cast into the (four) static 1 silk type touch panel, which also serves as the transmissive TM month support body 31, and also serves as an adhesive layer 41. 201234140 = the thin line 21, the transparent support 32 for the electrode, and the structure of the adhesive layer 41 which is also used as the insulating layer, and the contact person (the figure of the fish line (10) of the thin line 21 will be The conductivity of the upper electrode is the same. Further, the conductive thin wires 22 of the J electrodes are discriminated from each other in a direction other than bi. Shown 'for the conductive thin lines 21, from the surface of the arrow. The conductive thin wire 21 of the trap (10) is adjacent to the transparent wire 22' to recognize the surface of the conductive thin wire 2 2 located on the side of the support from the direction of the arrow b2. When the distance dl is a person's turn _ from the case of the majority (^.1_), it is not easy to feel the unevenness of the hue. [When a plurality of conductive thin wires are used to form one electrode (for example, the sensing portion of the electric capacitance is a mesh shape or a long lattice shape), as shown in Fig. = a plurality of conductive thin wires on the surface of the transparent support The area of the array 3 and the area on which the plurality of conductive thin lines are connected on the other side and the length of the d3 are usually recognized by a person, and the color is not recognized according to the formation conditions of the electrodes as shown in FIG. The following inventions were thus completed. In addition, Fig. 2 is a view schematically showing a cross section when the square lattice of Fig. 9 is cut parallel to the long side of the lattice.

由光罩110與光罩120對感光材料進行。因光罩11〇與光 罩120是用於藉由顯影銀來形成後述的圖7與圖8的電極 圖案的遮罩,故光罩110與光罩12〇是相當於圖7與圖8 的電極的細線部分透光的遮罩。因此,光罩11〇與光罩12〇 24 201234140 是圖案不同而非相同的遮罩。如以上的說明般,111與121 是遮罩的開口部,112與122是遮罩的遮光部。透過了遮 罩的開口部的光於感光層的131、141的部分的鹵化銀乳劑 中形成潛像。形成有該潛像的131與141的部分藉由其後 的顯影處理而形成顯影銀的圖案。於因遮罩的遮光部而未 得到曝光的感光材料的未感光部132、未感光部142中, 因疋影處理而未感光的鹵化銀乳劑粒子溶解並自層内流 出,而成為透明的膜152、膜162。 如上所述,當使用圖案不同的遮罩進行自感光材料的 兩面的曝光時,會產生如下的問題。雖然透過了光罩11〇 的開口部111的光於感光材料的13〗的部分形成潛像,但 剩餘的光亦透過透明支撐體,而於相反面的感光層61中亦 形成預料不到的潛像。此種問題僅靠曝光量的調節難以解 決’可藉由將具有吸收透過了感光層51的光的光學濃度的 防光暈層57及防光暈層67設置於感光材料中來應對。作 為其他方法,亦有利用增感色素改變感光層51與感光層

The layer), the second photosensitive layer (also layer), and the third photosensitive layer (layer) are coated as a three-layer photosensitive layer. The method in which the mercerized layer is divided into such a plurality of layers is the same as the method in which the emulsion layer of the silver halide photographic light-sensitive material is formed into a 〇 layer, an m layer, and a u layer in the order of sensitivity from 咼 to low, as described above. By performing multi-layering, sensitivity, gradation, and the like can be easily adjusted. In the present invention, in order to facilitate understanding of the layer, it is also abbreviated as a ruthenium layer, a m layer, and a u layer, but it does not indicate the level of sensitivity. The ruthenium layer as the third photosensitive layer is the photosensitive layer farthest from the transparent support, and the u layer as the first photosensitive layer is the photosensitive layer closest to the transparent support.

For example, each controllable surface "I degree can be used. Further, the matting agent is preferably one which remains after the film, does not impede transparency, and dissolves in the processing step. In the photosensitive layer of the present invention, a protective composition (not shown) may be provided. The term "protective layer" means a coating containing a clear or high-molecular polymer, and in order to prevent scratches or improve mechanical properties. The axis is in the photosensitive layer of the device. The thickness is preferably Μ 23 ϋ 201234140 μηη or less. The coating method and the formation method of the protective layer are not particularly limited, and a known coating method and formation method can be appropriately selected. An antihalation layer 57 and an antihalation layer 67 may be provided between the photosensitive layer of the present invention and the transparent support.

Although the optical density of the antihalation layer differs depending on the intensity or wavelength of the exposure light, it is preferably about 0 5 to 3 Torr. Next, a process for producing the transparent conductive sheet of the present invention using the material of the present invention described above will be described with reference to Figs. 4(a) to 4 . 4(a) is a transparent support 32, and FIG. 4(b) shows the photosensitive material of the present invention in which the upper photosensitive material layer 50 and the lower photosensitive material layer 60 are provided on both surfaces of the transparent support by coating. 5, FIG. 4(c) shows a view in which the photosensitive material of the present invention is exposed by a photomask, and FIG. 4(d) shows a developed silver electrode formed by a development fixing process immediately after exposure. Hereinafter, each step after exposure will be described. [Exposure] The photosensitive material 05 of the present invention is a photosensitive material in which a photosensitive layer is formed on both sides of a support. Therefore, in the present invention, as shown in FIG. 4(c), both sides of the photosensitive material are irradiated with l〇2a and l〇. 2b to expose. The light irradiation is performed on the photosensitive material via the photomask 110 and the photomask 120. Since the mask 11 and the mask 120 are masks for forming the electrode patterns of FIGS. 7 and 8 to be described later by developing silver, the mask 110 and the mask 12 are equivalent to those of FIGS. 7 and 8. A mask that transmits light through the thin line portion of the electrode. Therefore, the reticle 11 〇 and the reticle 12 〇 24 201234140 are masks that are different in pattern but not the same. As described above, 111 and 121 are openings of the mask, and 112 and 122 are light shielding portions of the mask. The light that has passed through the opening of the mask forms a latent image in the silver halide emulsion of the portions 131, 141 of the photosensitive layer. The portions of the latent images 131 and 141 are formed into a pattern of developed silver by subsequent development processing. In the non-photosensitive portion 132 and the non-photosensitive portion 142 of the photosensitive material which is not exposed by the light-shielding portion of the mask, the silver halide emulsion particles which are not photosensitive due to the shadowing treatment are dissolved and flow out from the layer to form a transparent film. 152. Film 162. As described above, when exposure of both surfaces of the photosensitive material is performed using masks having different patterns, the following problems occur. Although the light transmitted through the opening portion 111 of the mask 11 形成 forms a latent image on the portion of the photosensitive material, the remaining light also passes through the transparent support, and the photosensitive layer 61 on the opposite side also forms an unexpected image. Latent image. Such a problem is difficult to solve by merely adjusting the exposure amount. The antihalation layer 57 and the antihalation layer 67 having the optical density of light absorbed through the photosensitive layer 51 can be disposed in the photosensitive material. As another method, there is also a method of changing the color sensitivity of the silver halide emulsion of the photosensitive layer 51 and the photosensitive layer 61 by using a sensitizing dye.曰 Figure 5 is a model diagram of an exposure apparatus in the present invention. Light from both the light source 1a and the light source 100b is parallel light by the lens, and both surfaces of the photosensitive material are exposed through the mask. The exposure device portion including the light source from the light source in Fig. 5 is strictly positioned by the two exposure devices. The silver image formed by the mask 11 and the mask 12A having the pattern of Figs. 7 and 8 is strictly positioned so as to have a uniform pattern as shown in Fig. 9. In the form of FIG. 1〇25 201234140 to FIG. 12, the two conductive sheets are combined to form a touch panel, and the two conductive sheets are arranged in the same manner as the two-sided type of the present invention. As a light source for exposure, productivity is extremely poor. We can cite visible light and material (four) Wei. As the electromagnetic wave, for example, the exposure can also be carried out with a long amount of money. Further, the light source. The light source of the cloth may also be a specific wavelength exposure method, which may be as shown in FIG. 5, except that the conductive sheet formed in the above manner is a conduction direction of the surface and the conduction of the back surface of the through-pole. The directions are exposed to each other in an orthogonal manner, and then developed by a development process. 'Setting (Developing Process) In the present embodiment, the photosensitive layer is exposed and then processed.

Similarly, in the vicinity of the conductive thin line of the right-side eight-electrode conductive lattice portion (10), the same as the dotted line 19 (22), the conductive lattice portion 14B is not turned on. The line 22 is also non-conducting, and is imaginary; ::: -rt: rr == is formed on the extension line of the both ends of the long line of the square lattice and is preferably used for the large screen, the present invention] 2 ITO has a high resistance value and a mesh or lattice forms a diamond-shaped portion, and contains a low-resistance thin wire. Hereinafter, the description will be made by using a square square with a low square resistance and a bright square lattice, but it does not hinder the use of the long square 32 201234140. The line width of the conductive thin wires forming the conductive lattice portion is preferably 1 μm or more and 10 μm or less, more preferably 2 μm or more and 6 or less. When the range is Ιμηη or more and 10 μηη or less, an electrode having a low resistance can be formed relatively easily. The thickness of the conductive thin wire forming the conductive lattice portion is preferably 〇1 μm or more and 1.5 μπι or less, more preferably 〇 2 μmη or more, and 〇8 瓜瓜以下以下. When the right side is in the range of 0.1 μηι or more and 1.5 μηι or less, it is relatively easy to form an electrode having low resistance and excellent durability. The length of the side of the conductive lattice portion 14A and the conductive lattice portion 14A is preferably 3 mm to 10 mm, more preferably 4 mm to 6 mm. If the length of the side is 3 mm to 1 Gmm, it is less likely to cause the same problem as the problem that the detection is not caused by the shortage of the sensed electrostatic capacitance (4), or the position detection accuracy is lowered. ^2 = τ: μηι . When the length of the side of the unit lattice is in the above-described range, and the front side of the transparency can be favorably maintained, the display can be recognized without any sense of discomfort. 4 Furthermore, the upper and lower electrodes of the touch panel of Fig. 8 are orthogonal, but as long as the decision touch == sigh is set to be arbitrary. _ private does not make a mistake, then the thin line: two = rY: = r sub-guided control panel has the following characteristics: If the panel of this 33 201234140 = the direction of the electric display of the image display device (four), The conductive sheet in which the patterned electrode of the stack = 2 is less likely to be produced can significantly reduce the electric resistance as compared with the configuration using one sheet of 1το ❹田*. Therefore, although the conductive wire of the present invention is applied to, for example, a touch panel, the response speed can be increased, and the touch == size can be promoted. "Two-sided conductive sheet with improved color tone difference" As described in the means for solving the problem, the conductive sheet of the present invention is capable of reducing the upper electrode formed on both sides of a transparent support for improving productivity. A conductive sheet having a poor hue of the lower electrode. The improvement of the color difference can be achieved by a transparent conductive sheet having a surface electrode of a conductive sheet (also referred to as a double-sided conductive sheet) formed on both surfaces of the one transparent support and the lower electrode (away from the double-sided conductive sheet) away from the transparent support The transparent conductive sheet having an absolute value of the difference between the reflection chromaticity b!' of the electrode surface on the side of the electrode and the reflection chromaticity b2* of the electrode surface on the side of the transparent column body on the side of the electrode is substantially equal to or less than 2, and thus substantially Coordinate the face with a sense of coordination. Further, the color tone at the time of observation is preferably such that it is easily recognized as black on the visual field. The measured values of b/ and b/ are neutral in the vicinity of 〇. However, in the present invention, if it is set as follows, the recognizer can easily recognize black. In the present invention, 'as b/' is preferably 2. 2. 〇 < b/SO ' is more preferably -1.5 < br$-0.3, particularly preferably -l.Ocb/s-OJ. Preferably, b2#' is -10<b2, i.〇, more preferably -0.7<34 201234140 4U^y/pif b2 $〇·5 ’ is particularly good - 〇.5<b2 $0.2.

By doing so, the unevenness of the color of the electrode surface and the hue (neutral) which is close to black can be removed, and the visibility is further improved. Here, the reflection chromaticity bi of the electrode surface on the side of the surface electrode away from the transparent support is measured when the reflection chromaticity of the electrode surface of the region of d2 of FIG. 2 is measured from the discriminator side of the upper portion of the figure. y value. In addition, the reflection chromaticity h of the surface of the electrode of the transparent support is measured, and the reflection chromaticity of the surface of the electrode of the ubiquitous region of Fig. 2 is measured from the discriminator side of the upper part of the figure. *value. The *, *, * reflection chromaticity b* is the characteristic value defined by the ιΛγ color system. The Lab color system is a method of coloring established by the International Commission on Illumination (intemati〇nai Comrmssion on Illuminati〇n, αΕ) in 19-6. The L value, a value, and b* value in the present invention are by jIS_z8729. : 1994 = The value obtained by the method of measurement is the measurement method of the muscle survey 9 /", there is a measurement method using reflection, and a measurement method using transmission, and the value measured by reflection is used in the present invention. * The L* value, the a* value, and the b value in the _b color system are as well known. The L value represents the brightness, and the a* value and the b* value represent the hue and chroma. Specifically, if the number is taken, it means the hue of red. If it is a negative sign, it does not show a green hue. If the b* value is positive, it is a yellow hue, and if it is negative, it is a blue hue. In addition, the greater the value of a, the b* value of the value of b* 35 201234140 both indicate that the color of the color is larger and brighter, and the smaller the absolute value, the smaller the chroma. In the present invention, the 'a* value is small in the observation direction (bi direction and b2 direction). On the other hand, the change in the b* value caused by the observation direction of the electrode is larger than the value of a, and specifically, it is easy to be color unevenness by changing from yellow to blue, or from blue to yellow. identify. The details of the measurement method are described in the examples. The improvement of the color tone of the electrode surface of the above-mentioned double-sided conductive sheet is achieved by the photosensitive material of the present invention which has been described. Hereinafter, a preferred embodiment of each layer of the photosensitive layer for reflection chromaticity adjustment described above will be briefly described. In the system for increasing the amount of silver for lowering the resistance and increasing the density of silver in order to impart conductivity to the silver image formed by development as in the present invention, the surface of the electrode of the silver electrode which is away from the side of the transparent support is developed. The hue tends to be blue, and the hue of the electrode surface of the developing silver electrode near the side of the transparent support tends to be yellowish. As a cause of the hue phenomenon, it is considered that in a system having a large amount of silver and a high silver density, the photosensitive layer is separated from the side of the photosensitive layer away from the transparent support, and the development is formed on the surface side by a fresh developing solution. In contrast, as the developer penetrates into the lower layer in the photosensitive layer, the accumulation of the shadowing material occurs, and the development of the developer is suppressed, and the surface layer is consumed. Therefore, the solution is composed of a solution having a small amount of the inhibitor. Development is carried out. Along with this, the shape of the filament of the developed silver was different on the upper layer side (the side of the enamel layer side)/the lower layer side of the photosensitive material, and it was estimated that it was observed as a color product. Based on such inference, the preferred form of the present invention is described in items [1] to [30] of the means for solving the problem. The above two-sided conductive sheet of the present invention can be preferably used for a touch panel, particularly an electrostatic capacitive touch panel. Further, the present invention can be used in appropriate combination with the techniques of the publications and the international publications described in Table 1 below.

The composition of the photosensitive layer coating liquid was used as a standard, and the volume ratio of the silver to the binder in Table 2 was adjusted to adjust the type and amount of the sulphur compound, and the surface layer was prepared. (U layer, m layer, layer) and a coating liquid of three layers (u layer, 111 layer, layer) on the back surface. ^, 100 μΐη of the polyethylene terephthalate (PET) film was subjected to corona discharge treatment on both sides, and a gelatin primer having a thickness of 〇丨μιη was disposed on both sides to set an optical density on the undercoat layer. 1G and including the antihalation layer of the (four) material by the test of the f liquid, thereby forming a branch body. The photosensitive layer coating liquid prepared and prepared above was applied to both sides of the remote support. In the coating, the amount of silver is set as a reference so that the total amount of silver contained in the three layers (u layer, added layer, and 0 layer) of the photosensitive layer becomes the thickness of the silver image in Table 2 and Table 3 (unit The shape of the way is μιη). In the present case, the developed silver image thickness was calculated on the condition that the applied emulsion + all of the impurities were converted into developed silver ' and the developed silver density (indicating the silver/binder volume ratio) was 1 〇 5 201234140. Further, the film thickness of each layer of the photosensitive layer (u layer, m layer, and ruthenium layer) is set so that the film thickness becomes 1 · 2 · 1 in the photosensitive material 1 to the photosensitive material 15 in the photosensitive material 16 to The photosensitive material 31 is set so as to have a film thickness ratio recorded in () of the silver density row of the formulation value of Table 3. Further, a value of 1 in () indicates a single layer, and a value of 0.2 in () indicates that the film thickness of the layer is 20% of the entire photosensitive layer. Therefore, in Table 3, the total thickness of the silver and the binder of the photosensitive layer 3 layer is 0.7 μm in the surface other than the surface and the back surface of the photosensitive material 19 and the surface of the photosensitive material 31, respectively. The thickness of the photosensitive material 31 is set such that the silver and the binder are each 1.5 μm thick. The surface and the back surface of the photosensitive material 19 are the same as the silver/adhesive volume ratio of the ruthenium layer to the surface and the back surface of the photosensitive material 16. That is, the ruthenium layers of the two have the same coating thickness of the binder, and only the thickness of the silver is different. In the comparison of the photosensitive material 19 and the photosensitive material 18, in the photosensitive material 18, the amount of silver which is produced by setting the silver/binder volume ratio of the ruthenium layer to 〇.3 in the m layer and the binder In contrast, since the amount of decrease in the amount of silver in the ruthenium layer is not adjusted in the photosensitive material 19, the thickness of the developed silver image in Table 3 is thinner than that of the other photographic materials. The silver bromide content of the emulsion was from the photosensitive material 1 to the photosensitive material 15, and all the layers were set to 30 mol%, and the photosensitive material 16 to the photosensitive material 31 are described in Table 3. The volume of the silver and the binder in Table 2 was converted into a volume by the conditions of the development of the 201234140 male and the density of the adhesive of the silver (3) as described above. Further, the f ^ degree is 1.34, which is a density which can be _, and when # other high molecular compounds are used, the conversion corresponding to the compound is required. In addition to f, the amount of the sulfhydryl compound added to the photosensitive layer coating liquid is expressed as mg in an amount of 1 g of the silver base. The structure of the Wei group compound used is described after Table 3. Further, a protective layer containing a gelatin containing a preservative as a coating of 〇·15 μηι was provided on the above-mentioned enamel layer. The three layers of the photosensitive layer and the protective layer of the three layers were simultaneously coated by a coater to prepare a photosensitive material photosensitive material 31. ~ (exposure and development treatment) Next, the above-mentioned photosensitive material 1 to photosensitive material 31 were subjected to double-sided exposure using a high-pressure mercury lamp using the double-sided exposure machine of Fig. 5, and the mask for pattern formation of Fig. 7 was used as a surface. On the side mask, the mask for pattern formation of FIG. 8 was used as a back cover for exposure. The window for light transmission of the mask to be used is the same pattern as that of Figs. 7 and 8, and the unit square lattice (10) forming the lattice is 3 divisions, and the side length of the lattice is · μηι 〇 after exposure, using the following The developer is developed, and the solution (product name: N3X_R: manufactured by Fujifilm Co., Ltd., CN16X) is subjected to development treatment, then rinsed with pure water, dried, and then subjected to rolling treatment of the sample.

In the same manner as in Comparative Example 1, Comparative Example 2 and Comparative Control Panel, Example i to Example 28 were produced. of. (Evaluation) 43 201234140 The following evaluation was carried out using the double-sided electrode type transparent conductive sheet 1 to the transparent conductive sheet 31 produced above. (1) Measurement of reflection chromaticity b/ and reflection chromaticity b2* The sample for measurement was placed on a BCRA black tile (glossy plate), and the measurement was carried out from the direction of 0° at 45. The spectral reflectance of the light received in the direction. A preferred tile is a BCRA black tile (glossy version) manufactured by SAKATA INX ENG Co., Ltd., which has a reflection chromaticity of l* of 3.6 and a* of -0.9 ′b* of -0.6. As a reflection densitometer, a Spectro Eye LT manufactured by GretagMacbeth can be used. Furthermore, for the measurement sample of the reflected chromaticity, the mask 110 for surface exposure is a mask using a window having a size capable of performing reflection chromaticity measurement, instead of a normal mask for pattern exposure, and is exposed on the back side. The exposure of the entire face without the use of a mask is implemented. The measurement of the reflection chromaticity is performed from the surface side, and the reflection chromaticity of the exposed portion of the surface on which the silver image is formed is defined as the reflection chromaticity b/', and the reflection of the unexposed portion of the surface is measured. The chromaticity is set to the reflection chromaticity b2*, and the absolute value of the difference Δ!/ (also expressed as jb*) is calculated from the obtained reflection chromaticity b/ and the reflected chromaticity V. (2) Evaluation of the visibility The two-sided electrode type transparent conductive sheet produced by observing the oblique direction of the respective directions in the vertical direction is characterized by unevenness in the color of the reflected light, shaking of the reflected light, and contour of the electrode.

The double-electrode-type transparent conductive sheet of Comparative Example 1 in which no compound is used in any of the photosensitive layers on the front surface and the back surface has a sufficient resistance value unevenness as an electrode constituting the i-type capacitive touch panel. Poor identification. Further, if Α π^ hue 2 and Comparative Example 3, the silver and the binder were increased as in the comparative example, and the color unevenness was further deteriorated. The volume ratio, that is, the increase in silver density, and on the other hand, in the photosensitive layer on either side of the surface or the back surface, in the examples 1 to 12 in which the 2012 20120140 mercapto compound is used, it can be reduced without increasing the resistance value with respect to the comparative example. The color is uneven and the recognition is improved. Regarding the surface on which the mercapto compound was used, although the radical compound was added only to the back surface in the present experiment, it was preferably added on the back side. Among the back surfaces, it is preferably added to the u layer as a photosensitive layer close to the support, as compared with the comparison of Example 1 and Example 11, or the comparison of Example 5 and Example 12, it is preferable to limit the radical compound. In the lower layer (ie, the layer near the support). Further, the effect of improving the color tone differs depending on the kind of the mercapto compound, and in the examples 7 to 9 in which the monocyclic compound C, the mercapto compound d, and the mercapto compound E are used, compared with the case where no mercapto compound is not used. In Example 1, the effect of color tone improvement is extremely small. On the other hand, it is understood that the use of the compound A, the compound B, the compound F, and the compound G as examples of the condensed ring compound, and the examples 4 to 6 show a large improvement effect of uneven color tone, and it is particularly preferable to use it in 2_酼. Examples 1 and 5 of Compound F having a sulfo group and a carboxyl group at the 4- to 7-position of the benzimidazole and Compound G. Further, in order to further reduce the resistance, the silver density was set to 2, and the color unevenness of Example 3 in which the compound F was added to the back surface photosensitive layer u was small, and the resistance was lowered. Further, in Example 10, although the fluorenyl compound F was added to the photosensitive layer on the back surface, and the thickness of the silver image was increased from 〇·7 to 15, the display was able to reduce the resistance of the lower electrode of the _ surface (four). The sensing ability of the electrostatic capacitance is improved, and the unevenness of the color of the electrode at the time of recognition can be improved. Further, the following can be seen from the results of Table 3. 50 201234140 Examples 1 to 12 of Table 2 above are examples of a composition in which a silver halide emulsion is used with a silver bromide emulsion containing 30 mol% of silver bromide and a volume ratio of silver to a binder (silver density) is used. The photosensitive layer is fixed, and the layer (u layer) of the photosensitive layer close to the branch body contains a composition example of a sulfhydryl compound. In contrast, Examples 13 to 28 of Table 3 are used to have a silver bromide content. Changed to 50% by mole or 70% by mole, or the volume ratio (silver density) of the silver and the binder in the photosensitive layer in the thickness direction of the photosensitive layer (changing the specificity of the bismuth layer, the m layer, and the u layer) The example of the electrode formed by the photosensitive material of the silver density of the layer and the touch panel was improved as compared with the examples 1 to 12, and the result of the absolute value of the difference in reflected chromaticity was improved. Examples 13 to 19 have the feature that the electrodes on both sides of the transparent support are designed to use a double-sided conductive sheet formed of the same photosensitive material. Each of the samples has a feature that the observed color tone does not change even if the direction of the conductive sheet is changed, and has the following advantages: it is easy to recognize in the formation of the touch panel, and the back surface of the watch is not generated. problem. The common points of Examples 13 to 16 are that the development inhibitor F (the sulfhydryl compound) of the present invention is added to the layer (u layer) of the side of the transparent support which is adjacent to the support on both sides, Example 13 and Examples 14 is a sample in which the silver bromide ratio of all layers was changed from 30 mol% to 50 mol% or 70 mol%. Example 15 and Example 16 are silver/adhesive layers of the tantalum layer to which the developing treatment liquid was initially contacted. The sample whose volume ratio was changed from 1.0 to 0.3 was obtained as the absolute value of the difference in reflection chromaticity (also expressed as |ΔΙ/| or |zlb*|), and the sample of 201234140 was re-conducted with no problem. The volume of the ί rate averages the silver and the thick money is less. _Π5^ ^The recording of the conductive layer _body ^!^, must help the case, if it contributes to conductivity, but the thickness of the silver/binder of the u layer); & For the melon layer and the improvement of the guide material, it is also possible to provide a layer having a wide color and a thickness of preferably 々Μ2. It is preferable that the contribution of the conductivity is less than 30%^the thickness of the silver-containing __thickness, and the ratio of the layer = the ratio of the layer is increased. Also, the volume fraction of human and an, the development inhibitor layer is added ΐ::=ίσΓ and is a sample according to Example 18, Example 19, Example (4) f slightly = clever blue side. By grouping the above three elements 5, the desired uneven color tone is obtained. Examples 20 to 28 have the following features: The two sides of the transparent slab body are made of a two-sided guide (also referred to as an asymmetrical type) formed of different photosensitive materials. Each of these samples has the advantage of independently controlling the color tone of the surface electrode and the back surface electrode, i.e., independently making the color tone of the surface electrode and the back surface electrode close to an optimum value. Examples 20 to 28 can be avoided by the content of the surface, the back, or the enamel layer, u 52 201234140. : body =; ===, silver/adhesive, and must be based on the surface of the surface.
