技术领域 FIELD

[0001] 本发明涉及触摸屏用涂布组合物、由该涂布组合物形成的涂膜、以及具有该涂膜的触摸屏。 [0001] The present invention relates to a touch screen coating composition, a coating film formed from the coating composition and the coating film having a touch screen.

背景技术 Background technique

[0002] -直以来,为了各种目的而在玻璃、陶瓷、金属、塑料等基材表面形成无机被膜。 [0002] - straight since, for various purposes to form an inorganic film on the surface of glass, ceramic, metal, plastic and other substrates. 通过在基材表面形成无机被膜,可赋予基材以电特性、光学特性、化学特性、机械特性等。 By forming an inorganic film on the substrate surface, it can be imparted to the substrate electrical properties, optical properties, chemical properties, mechanical properties and the like. 因此,这些无机被膜作为导电膜、绝缘膜、光线的选择透过或吸收膜、碱金属溶出防止膜、耐化学品膜、硬质涂膜等而实用化。 Therefore, these inorganic film as the conductive film, an insulating film, a light absorption film or permselective, an alkali metal elution preventing film, chemical resistance film, the hard coating film and the like practical.

[0003]作为形成这种无机被膜的方法,可例举CVD(化学气相沉积(Chemical Vapor Deposition))、PVD(物理气相沉积(Physical Vapor Deposition))、派射等气相法或使用醇盐化合物等的液相法。 [0003] As a method of forming such an inorganic film may include CVD (chemical vapor deposition (Chemical Vapor Deposition)), PVD (physical vapor deposition (Physical Vapor Deposition)), a gas phase method or the like to send radio using an alkoxide compound the liquid phase method.

[0004] -般来说,气相法需要真空蒸镀装置之类的高价且大规模的装置。 [0004] - In general, large-scale and expensive device like a vacuum vapor deposition apparatus fumed needs. 此外,也存在能成膜的基材的大小和形状受到限制的问题。 In addition, there is a problem of size and shape capable of forming the substrate is restricted. 另一方面,作为使用醇盐化合物等的液相法,已知所谓的溶胶一凝胶法。 On the other hand, the use of an alkoxide compound as a liquid phase method, a known so-called sol-gel method. 该方法具有能进行大面积的涂布、能应对图案形成等优点。 The coating method can be performed with a large area, and the like can cope with patterning advantages. 因此, 通过液相法制成的无机被膜被大量用作电子器件中的涂膜(例如参照专利文献1)。 Accordingly, a large number of electronic devices used by coating an inorganic film formed by liquid-phase method (e.g., refer to Patent Document 1). 特别是最近正在研究在触摸屏中的应用。 Especially recently applied in the touch screen being studied.

[0005] 近年来,随着智能手机的普及,手机的显示画面大型化。 [0005] In recent years, with the popularity of smart phones, the phone's display screen size. 因此,正在大量进行能利用显示器的显示来进行输入操作的触摸屏的开发。 Thus, the display is being done using the display can be developed touch screen input operation. 利用触摸屏,因为不需要按压式的开关等输入单元,所以能实现显示画面的大型化。 Using the touch screen, since no push type switch or the like input means, a display screen can be realized in size.

[0006] 触摸屏检出手指或笔等所触摸的操作区域的接触位置。 [0006] touchscreen detecting a contact position of the finger or a pen touches the operation area. 利用该功能,触摸屏被用作输入装置。 With this function, the touch screen is used as an input device. 接触位置的检出方式有电阻膜方式、静电电容方式等。 Detecting the position of contact with a resistive film type, capacitive type. 电阻膜方式中使用相向的两炔基板,与之相对,静电电容方式中,所用的基板可以是一块。 Resistive film method using two facing alkyne substrates, as opposed to the capacitance, the substrate used may be one. 因此,通过静电电容方式,能构成薄型的触摸屏,适合于便携式机器等,所以近年来正在大量地进行开发。 Thus, a capacitive type, can form a thin touch screen, suitable for portable machines and so on, so in recent years are a large number of development.

[0007] 专利文献2中公开了一种静电电容方式的触摸屏。 [0007] Patent Document 2 discloses a touch panel of an electrostatic capacitance method. 该触摸屏中,在透明基板的一个面上配置用于检出X方向的坐标的第一透明电极和用于检出Y方向的坐标的第二透明电极, 在各自的交叉部分隔着层间绝缘膜,从而使其不导通。 A first transparent electrode of the touch screen, on one surface of a transparent substrate configured for detecting X-coordinate direction and the second transparent electrode for detecting a Y coordinate direction, the intersection of the respective interlayer insulating film, so that it is not turned on.

[0008] 触摸屏安装在液晶显示装置等显示装置中,作为能检出触摸位置的带有触摸屏功能的显示装置使用。 [0008] The touch panel mounted on a display device like a liquid crystal display device, used as a display device with a touch panel function of the touch position can be detected. 操作触摸屏的人透过触摸屏来观察显示装置,因此透明电极中使用光的透过特性优异的构件。 To the person operating the touch screen viewed through the touch-screen display device, thus using the transparent electrode having excellent light transmission characteristics member. 例如使用ΙΤ0(氧化铟锡(Indium Tin Oxide))等无机材料。 For example ΙΤ0 (indium tin oxide (Indium Tin Oxide)) and inorganic materials. 此外, 作为层间绝缘膜,使用能进行图案形成的绝缘性的丙烯酸材料等。 Further, as an interlayer insulating film, an acrylic material or the like can be performed using the insulating pattern formed.

发明内容 SUMMARY

[0013] 发明所要解决的技术问题 [0013] The invention solves the technical problem

[0014] 上述触摸屏中,因为有时操作区域会与指尖或笔尖实际接触而受到按压等,所以要求强度和高可靠性。 [0014] In the touch panel, since the operation area may actually be in contact with a fingertip or pen tip is pressed and the like, so that required strength and high reliability. 因此,正在进行在隔着层间绝缘膜重叠的第一和第二电极上设置保护膜的研究。 Thus, it is disposed on the first electrode and the second interlayer insulating film overlapping the protective film studies.

[0015] 作为保护膜,使用能进行图案形成的丙烯酸材料。 [0015] As the protective film, using acrylic material capable of pattern formation. 然而,丙烯酸材料是有机材料, 因此作为保护膜的硬度不足。 However, the acrylic material is an organic material, the hardness of the protective film as insufficient. 此外,使用ΙΤ0等作为透明电极的情况下,与ΙΤ0的密合性差, 成为使触摸屏的可靠性下降的一大因素。 In addition, like as ΙΤ0 transparent electrode, adhesion ΙΤ0 difference, the touch screen has become a major factor in lowered reliability. 而且,丙烯酸材料难以进行采用胶版印刷等印刷技术的膜形成。 Further, the acrylic film-forming material is difficult to offset printing and other printing technologies. 因此,在膜形成时,需要采用工序复杂的光刻技术。 Thus, at the time of film formation step we need complicated photolithography technique.

[0016] 因此,作为保护膜,进行了以无机材料代替丙烯酸膜作为成分的涂膜的研究。 [0016] Thus, as a protective film, an inorganic material instead of study acrylic film as a component of the coating film is. 以无机材料作为成分的膜的情况下,一般硬度高,作为触摸屏的涂膜可期待高可靠性。 In the case where an inorganic material is used as a membrane component, generally a high hardness, the coating film as a touch screen with high reliability can be expected. 因此,对于以无机材料作为成分的涂膜,要求能进行采用印刷技术的膜形成,并且显示出与上述丙烯酸材料等有机材料的层间绝缘膜的高密合性。 Thus, for a coating film to an inorganic material as a component, requires technology capable of forming a film by printing and exhibits high adhesion between the insulating film layer and the organic material is an acrylic material.

[0017]此外,静电电容方式的触摸屏中,形成有IT0等透明电极的区域和未形成透明电极的区域之间在反射率方面产生差异。 [0017] Further, the capacitive touch panel formed a difference in reflectivity between the region and the region of the transparent electrode is not formed are transparent electrodes like IT0. 因此,有可以观察到透明电极的图案、使显示性下降的问题。 Thus, there can be observed a pattern of transparent electrodes, so that the problem of decreased display.

[0018] 如上所述,在现有的触摸屏中,使用丙烯酸膜作为透明电极上的保护膜材料。 [0018] As described above, in the conventional touch screen, an acrylic film is used as the protective film on the transparent electrode material. 但是,此时,对于丙烯酸膜的折射率特性完全没有任何考虑。 However, at this time, the refractive index characteristics of the acrylic film is absolutely no consideration. 因此,无法期待丙烯酸膜有使透明电极图案不显眼的效果。 Thus, an acrylic film can not be expected with a transparent electrode pattern inconspicuous effect. 因此,使用以无机材料代替丙烯酸膜作为成分的涂膜的情况下, 该涂膜较好是使透明电极图案不显眼。 Therefore, when the inorganic material used as the coating film instead of the acrylic component, which is preferably a transparent electrode film pattern inconspicuous. 具体而言,优选使用考虑到折射率的涂膜。 Specifically, the coating film is preferably used taking into account the refractive index.

[0019] 本发明是鉴于这一点而完成的发明。 [0019] The present invention has been accomplished in view of this disclosure. 即,本发明的目的在于提供一种适用于触摸屏、能实现高可靠性、折射率得到控制的涂膜,以及能形成这样的涂膜的涂布组合物。 That is, an object of the present invention is to provide a suitable touch screen, high reliability can be achieved, controlled refractive index coating film, and a coating composition capable of forming such a coating film.

[0020] 此外,本发明的另一目的在于提供一种电极上具有折射率得到控制、能实现高可靠性的涂膜的触摸屏。 [0020] Further, another object of the present invention is to provide an upper electrode having a controlled refractive index, high reliability can be realized in a touch screen coating.

[0096](防析出剂/金属氧化物)彡1 [0096] (anti-precipitating agent / metal oxide) San 1

[0097] 如果上述比例小于1,则形成涂布被膜时的防金属盐析出的效果小。 [0097] If the above ratio is less than 1, preventing the formation of small metal film during coating deposition effect. 另一方面,大量使用防析出剂对涂布组合物不会造成任何影响,但较好为200以下。 On the other hand, the use of a large number of anti-precipitating agent to the coating composition will not have any impact, but is preferably 200 or less.

[0098] 可以于在金属盐的存在下进行水解•缩合反应时将金属醇盐、特别是硅醇盐、钛醇盐或硅醇盐和钛醇盐加入到防析出剂中,也可以在水解•缩合反应结束后添加。 [0098] This can be carried out in the presence of a metal salt • hydrolysis condensation reaction of metal alkoxide, particularly silicon alkoxide, titanium alkoxide or silicon alkoxide and titanium alkoxide is added to the anti-deposition agent, may be hydrolyzed • the end of the condensation reaction.

[0101] 如果该比例小于〇.〇1,则所得被膜的机械强度不足,因此不理想。 [0101] If the ratio is less than 〇.〇1, the mechanical strength of the resulting coating film is insufficient, such being undesirable. 另一方面,如果大于0.7,则涂膜对玻璃基板和透明电极等的基材的密合性下降。 On the other hand, if it exceeds 0.7, the coating film adhesion to the substrate to decrease a glass substrate and a transparent electrode or the like. 还有,在450°C以下的低温下烧成的情况下,也有所得涂膜的耐化学品性下降的倾向。 Further, in the case of baking at low temperatures below 450 ° C, and the resulting coating film tends to decrease in chemical resistance. 其中,该比例更好为0.01~0.6。 Wherein the ratio of preferably from 0.01 to 0.6.

[0102] 本发明的涂布组合物中,只要不损害本发明的效果,则可以含有上述成分以外的其它成分、例如无机微粒、金属氧烷低聚物、金属氧烷聚合物、均化剂、表面活性剂等成分。 [0102] The coating composition according to the present invention, as long as the effects of the present invention are not impaired, may contain other components than the above components, such as inorganic fine particles, the metal siloxane oligomer, the metal siloxane polymers, leveling agents and surfactant ingredients.

[0106] 作为胶体溶液的分散介质中使用的有机溶剂,可例举甲醇、乙醇、丙醇、丁醇、乙二醇、丙二醇、丁二醇、戊二醇、2-甲基-2,4-戊二醇、二乙二醇、二丙二醇、乙二醇单丙醚等醇类;甲基乙基酮、甲基异丁基酮等酮类;甲苯、二甲苯等芳香族烃类;二甲基甲酰胺、二甲基乙酰胺、N-甲基吡咯烷酮等酰胺类;乙酸乙酯、乙酸丁酯、γ-丁内酯等酯类;四氢呋喃、1,4_ 二tl恶:烷等醚类。 [0106] As the organic solvent used in the dispersion medium of the colloidal solution may, for example, methanol, ethanol, propanol, butanol, ethylene glycol, propanediol, butanediol, pentanediol, 2-methyl-2,4 - pentanediol, diethylene glycol, dipropylene glycol, ethylene glycol monopropyl ether alcohol; methyl ethyl ketone, methyl isobutyl ketone and the like; toluene, xylene and the like aromatic hydrocarbons; two dimethylformamide, dimethylacetamide, N- methyl pyrrolidone; ethyl acetate, butyl acetate, [gamma] butyrolactone; tetrahydrofuran 1,4_ two tl evil: ether such . 其中较好是醇类和酮类。 Wherein preferred alcohols and ketones. 这些有机溶剂可以单独或两种以上混合后作为分散介质使用。 These organic solvents may be used singly or as a mixed dispersion medium.

[0107] 将上述金属醇盐和金属盐换算成金属氧化物的情况下,本发明的涂布组合物中的固体成分浓度较好是在〇. 5重量%~20重量%的范围内。 In the case [0107] The above metal alkoxides and metal salts in terms of metal oxide, solid content concentration of the coating composition of the present invention is preferably in the range of% to 20 wt% of the square. 5 wt. 如果固体成分多于20重量%,则不仅涂布组合物的贮藏稳定性差,而且难以进行涂膜的膜厚控制。 If the solid content is more than 20 wt%, not only the difference in storage stability of the coating composition, but it is difficult to control the thickness of the coating film. 另一方面,固体成分少于0.5重量%的情况下,所得涂膜较薄,为了得到规定的膜厚而需要多次涂布。 On the other hand, a solid content of less than 0.5% by weight, the resulting thin film, in order to obtain a predetermined thickness and require multiple coating. 其中,固体成分浓度更好为1重量%~15重量%。 Wherein, the solid content concentration of preferably from 1 wt% to 15 wt%.

[0108] 本发明的涂布组合物中,为了将上述第一和第二金属醇盐在上述金属盐的存在下水解得到缩合物而含有水。 [0108] The coating composition according to the present invention, in order to said first and second metal alkoxide in the presence of the metal salt hydrolysis and condensation product contains water. 该水的量相对于上述第一和第二金属醇盐的总摩尔量较好为2 ~24摩尔。 The amount of water with respect to the total molar amount of the first and second metal alkoxide is preferably from 2 to 24 mol. 该(水的量(摩尔)/(金属醇盐的总摩尔数)的比例为2以下的情况下,金属醇盐的水解不充分,使成膜性下降,使所得涂膜的强度下降,因此不理想。上述比例多于24的情况下,因为缩聚持续进行,所以使贮藏稳定性下降,因此不理想。其中,该摩尔比更好为2~20。 The case where the ratio of (amount of water (mol) / (total number of moles of a metal alkoxide) is 2 or less, hydrolysis of the metal alkoxide insufficient film-forming properties lowered, the strength of the resulting coating film decrease, therefore without over the above proportion is more than 24 case, since the polycondensation is continued, so that the decline in storage stability, which is not preferable. wherein the molar ratio is preferably from 2 to 20.

[0109] 涂布组合物中含有的金属盐为含水盐的情况下,其所含的水分参与水解反应,因此涂布组合物中所含的水的量中需要考虑该金属盐所含的水分。 Metal case [0109] contained in the coating composition is an aqueous salt, which contained water participation hydrolysis reaction, the amount of water contained in the coating composition needs to be considered that the water contained in the metal salt . 例如,共存的金属盐为铝盐的含水盐的情况下,其所含的水分参与反应,因此相对于水解所用的水的量,需要考虑铝盐所含的水分。 For example, the case where the coexistence of an aqueous metal salt is a salt of aluminum, which contains water participate in the reaction, the amount of water used in hydrolysis relative to aluminum contained in the water needs to be considered.

[0110] 本发明的涂布组合物可以形成适合于触摸屏的涂膜。 [0110] The coating composition of the present invention can form a coating film suitable for a touch screen. 该涂膜是以作为无机物的金属氧化物为主要成分的涂膜,与丙烯酸材料等有机材料的膜相比具有更高的强度。 The inorganic coating film is a metal oxide film as a main component, and organic material such as acrylic material having a higher film strength compared. 而且,在下述的触摸屏中可以用作电极的保护膜。 Further, in the following may be used as a touch screen protection film electrode. 涂膜具有适度的热伸缩特性,因此即使形成在构成触摸屏的有机膜上,开裂的发生也被抑制在最小限度。 Film has moderate thermal expansion characteristics, even if the touch screen is formed in the configuration of the organic film, the occurrence of cracking is suppressed to a minimum. 此外,折射率被控制在最佳范围内,以使因为能观察到透明电极图案而导致的显示装置的显示性的下降减少。 Further, the refractive index is controlled in the optimum range, so that the deterioration in display of a display device can be observed as a result of the transparent electrode pattern reduction.

[0111] 对于涂膜的折射率的控制,可通过控制涂布组合物的组成来实现。 [0111] For controlling the refractive index of the coating film, can be achieved by controlling the composition of the coating composition. 即,本发明的涂膜是使上述涂布组合物中含有的金属醇盐水解•缩合而制成的涂膜,通过选择金属醇盐的组成,可将形成的涂膜的折射率调整至规定的范围内。 That is, the present invention is to make the coating solution the metal alkoxide salt in the coating composition contained in a coating film made of the condensation • the refractive index of the coating film by selecting the composition of the metal alkoxide, can be adjusted to a predetermined form In the range. 例如,作为金属醇盐选择硅醇盐和钛醇盐的情况下,通过调整其混合比例,可以将所得涂膜的折射率调整至下述的规定范围内, 具体而言是1.45~2.1左右的范围内。 For example, a case of selecting a metal alkoxide of silicon alkoxide and titanium alkoxide, by adjusting the mixing ratio, the refractive index of the resulting coating film may be adjusted to be within a predetermined range described later, specifically about 1.45 to 2.1 range.

[0112] 即,将涂布组合物涂布成膜、较好是在干燥后进行烧成而形成的涂膜中,在所要求的折射率已经确定的情况下,可以确定金属醇盐、例如硅醇盐和钛醇盐的组成摩尔比,以实现该折射率。 Coating film [0112] That is, the coating film-forming coating composition, baking is preferably performed after the drying formed in the case where the refractive index required has been determined, a metal alkoxide may be determined, e.g. silicon alkoxide and titanium alkoxide molar composition ratio, to achieve the refractive index. 例如,由仅将硅醇盐水解而得的涂布组合物形成的涂膜的折射率为1.45左右的值。 For example, the refractive index of the coating film formed from a silicon alkoxide solution coating composition obtained by only a value of about 1.45. 另外,由仅将钛醇盐水解而得的涂布组合物形成的涂膜的折射率为2.1左右的值。 The refractive index of the coating film formed from titanium alkoxide hydrolysis coating composition obtained by only a value of about 2.1. 因此,欲将涂膜的折射率设定为约1.45~2.1之间的特定的值的情况下,可以以规定的比例使用硅醇盐和钛醇盐来制造涂布组合物,以实现该折射率值。 Accordingly, the refractive index of the coating film wishing the case of setting a specific value of between about 1.45 to 2.1, the ratio may be predetermined using silicon alkoxide and titanium alkoxide coating composition produced, to achieve the refractive values.

[0113] 此外,通过使用其它金属醇盐,也能进行所得涂膜的折射率的调整。 [0113] Further, by using other metal alkoxides, can be performed to adjust the refractive index of the resulting coating film. 另外,对于本发明的涂膜的折射率,除了组成条件以外,也可以通过选择成膜条件来调整。 Further, the refractive index of the coating film of the present invention, in addition to the conditions of the composition, may be adjusted by selecting the film forming conditions. 由此,能实现涂膜的高硬度,并且能实现所要的折射率值。 This makes it possible to achieve a high coating hardness, and to achieve the desired refractive index value.

[0114] 由本发明的涂布组合物得到涂膜的情况下,如上所述,较好是将涂布组合物的涂膜干燥,然后烧成。 [0114] the case where the coating composition obtained from the coating film of the present invention, as described above, the coating film is preferably dried coating composition, and then calcined. 干燥较好是在室温~150 °C下进行,更好是在40~120 °C下进行。 Drying is preferably carried out at room temperature ~ 150 ° C, preferably carried out at 40 ~ 120 ° C. 干燥时间较好是30秒~10分钟左右,更好是1~8分钟左右。 The drying time is preferably about 30 seconds to 10 minutes, preferably about 1 to 8 minutes. 作为干燥方法,优选使用加热板或热风循环式烘箱等。 As a drying method, preferably using a hot plate or a hot air circulating oven.

[0115] 考虑到触摸屏的其它构成构件的耐热性,烧成较好是在100°C~300°C下进行,更好是在150°C~250°C下进行。 [0115] Considering the heat resistance of the other member constituting a touch screen, the firing is preferably carried out at 100 ° C ~ 300 ° C, preferably carried out at 150 ° C ~ 250 ° C. 烧成时间较好为5分钟以上,更好为15分钟以上。 The firing time is preferably at least 5 minutes, more preferably at least 15 minutes. 作为烧成方法,优选使用加热板、热循环式烘箱、红外线烘箱等。 As the firing method, preferably using a hot plate, a thermal cycle oven, an infrared oven or the like.

[0116] 对涂布组合物的涂膜进行烧成来制造涂膜的情况下,所得涂膜的折射率根据烧成温度的不同而变化。 In the case [0116] The film coating composition is fired to manufacture a coating film, the refractive index of the resulting coating film varies depending on the firing temperature. 此时,烧成温度越高,越能提高涂膜的折射率。 At this time, the higher the firing temperature, the refractive index of the coating film can be improved. 因此,通过将烧成温度选定为适度的值,能进行所得涂膜的折射率的调整。 Accordingly, the firing temperature is selected to a moderate value, can be adjusted to the refractive index of the resulting coating film.

[0117] 由涂布组合物得到涂膜的情况下,如果在烧成前对涂膜照射紫外线(UV),则所得涂膜的折射率发生变化。 [0117] the case where the coating film obtained from the coating composition, if the coating film irradiated with ultraviolet rays (UV), the refractive index changes in the resulting coating film before firing. 具体而言,紫外线照射量越多,越能提高涂膜的折射率。 Specifically, the more the amount of ultraviolet irradiation, the refractive index of the coating film can be improved. 因此,为了实现所要的折射率,可以选择紫外线照射的有无。 Thus, to achieve a desired refractive index may be selected or absence of ultraviolet radiation. 特别是涂布组合物中含有的金属醇盐包含钛醇盐、锆醇盐或钽醇盐的情况下,通过对烧成前的涂膜的紫外线(UV)照射,所得涂膜的折射率发生变化,紫外线照射量越多,越能提高涂膜的折射率。 In particular a metal alkoxide contained in the coating composition comprises a titanium alkoxide, a zirconium alkoxide or a case where a tantalum alkoxide, irradiation of the refractive index, the resultant coating film to UV coating film before burning (UV) occurs changes, the more the amount of ultraviolet irradiation, the refractive index of the coating film can be improved. 涂膜能通过组成等条件的选择而实现所要的折射率的情况下,可以不进行紫外线照射。 Case selection conditions through a coating composition or the like to achieve the desired refractive index can not ultraviolet irradiation.

[0118]进行紫外线照射的情况下,通过选择其照射量,能调整涂膜的折射率。 [0118] case of ultraviolet irradiation, by selecting the irradiation amount thereof, the refractive index of the coating film can be adjusted. 涂膜为了得到所要的折射率而需要进行紫外线照射的情况下,例如可以使用高压汞灯。 For the case where the coating film is a refractive index to be required for the ultraviolet irradiation, for example, high pressure mercury lamp. 使用高压汞灯的情况下,以365nm换算,较好是总光照射100OmJ/cm 2以上的照射量,更好是300OmJ/cm2~ lOOOOmJ/cm2的照射量。 The case where high pressure mercury lamp, in terms of 365nm, irradiation amount is preferably 2 or more, the total light irradiation 100OmJ / cm, preferably irradiation amount 300OmJ / cm2 ~ lOOOOmJ / cm2 of. 作为紫外线的光源,除了高压汞灯外,可以使用低压汞灯、金属卤化物灯、氙灯、准分子灯等。 As the ultraviolet light source, in addition to high pressure mercury lamp, a low pressure mercury lamp, a metal halide lamp, a xenon lamp, an excimer lamp or the like. 使用高压汞灯以外的其它光源的情况下,可以照射与使用上述高压汞灯时等量的累积光量。 Other than the case of using a high pressure mercury lamp of the light source, the amount of integrated light may be irradiated with the same amount of time using the high pressure mercury lamp. 进行紫外线照射的情况下,也可以在干燥工序和烧成工序之间进行紫外线照射工序。 Case of ultraviolet irradiation, ultraviolet irradiation step may be performed between the drying step and the firing step.

[0119] 特别是涂布组合物中含有钛醇盐成分的情况下,具有在室温保存下粘度缓缓升高的性质。 In the case [0119] In particular the coating composition containing a titanium alkoxide component, having a viscosity at room temperature storage properties at elevated gradually. 这样的话,虽然不用担心在实用方面有很大问题,但精密地控制涂膜的厚度的情况下,较好是对温度等进行慎重的管理。 The case where this is the case, though do not worry there is a big problem in practical terms, but precisely control the thickness of the coating, it is preferred to temperature, etc. prudent management. 这样的粘度升高随着涂布组合物中的钛醇盐的组成比例的增多而变得显著。 Such viscosity increases with the increase of the composition ratio of the titanium alkoxide in the coating composition becomes remarkable. 认为其原因在于,钛醇盐与硅醇盐等相比水解速度更快,缩合反应也更快。 The reason is that, compared to the rate of hydrolysis of titanium alkoxide and silicon alkoxide faster and faster the condensation reaction.

[0120] 涂布组合物含有钛醇盐成分的情况下,为了减少粘度变化,优选下述两种制法(1) 和制法(2)。 [0120] case of coating composition containing a titanium alkoxide component, in order to reduce the viscosity change, preferably made of the following two methods (1) and production method (2).

[0121 ] (1)将钛醇盐在金属盐的存在下水解时,预先将二元醇类和钛醇盐充分混合后,根据需要与硅醇盐混合,在有机溶剂的存在下水解。 [0121] (1) a titanium alkoxide in the presence of a metal salt during hydrolysis, the glycols previously and sufficiently mixed titanium alkoxide, the hybrid needs silicon alkoxide, organic solvent in the presence of hydrolysis. 由此能得到粘度变化小的涂布组合物。 Thus a small change in viscosity can be obtained a coating composition. 认为该(1)的制法有效的原因在于,因为在将钛醇盐与二元醇类混合时有发热,所以在钛醇盐的烷氧基和二元醇类之间发生酯交换反应,对于水解•缩合反应稳定化。 Considered (1) an effective manufacturing method that reason, because the fever, the transesterification reaction occurs between the titanium alkoxide and alkoxy titanium alkoxide glycols when mixed with dihydric alcohols, • the condensation reaction for the hydrolysis stabilization.

[0122] (2)预先使硅醇盐在金属盐的存在下进行水解反应后,将其混合在与二元醇类混合的钛醇盐溶液中,进行缩合反应,得到涂布组合物。 After [0122] (2) pre-hydrolyzing the silicon alkoxide in the presence of metal salt, which is mixed in a mixing with diols titanium alkoxide solution, a condensation reaction, to give a coating composition. 由此能得到粘度变化小的涂布组合物。 Thus a small change in viscosity can be obtained a coating composition.

[0123] 认为该(2)的制法有效的原因是下述理由。 [0123] reason that the active (2) was prepared by the following reason. 即,虽然硅醇盐的水解反应以较快的速度进行,但随后的缩合反应与钛醇盐相比较慢。 That is, although the hydrolysis reaction of silicon alkoxide at a faster speed, but the subsequent condensation reaction as compared with a titanium alkoxide slower. 因此,在水解反应结束后,如果迅速地添加钛醇盐,则水解反应后的硅醇盐的硅烷醇基与钛醇盐均匀地反应。 Thus, after the end of the hydrolysis reaction, if the titanium alkoxide is added quickly, the reaction of the silanol group after the reaction of silicon alkoxide with a titanium alkoxide uniformly hydrolysis. 藉此,认为水解后的硅醇盐使钛醇盐的缩合反应性稳定化。 Thereby, that the silicon alkoxide of titanium alkoxide hydrolysis condensation reactive stabilized.

[0124] 已经尝试了将预先水解的硅醇盐和钛醇盐混合的方法。 [0124] A method has been tried previously hydrolyzed silicon alkoxide and a titanium alkoxide mixed. 但是,反应中使用的有机溶剂中不含二元醇类的情况下,无法得到贮藏稳定性优异的涂布组合物。 However, when the organic solvent used in the reaction of the free glycols, having excellent storage stability can not be obtained a coating composition. 2)所示的方法在由具有较快的水解速度的其它金属醇盐和硅醇盐得到涂布组合物的情况下也有用。 2) the method shown is also useful in the case where the coating composition obtained by salts and other metal alkoxides silicon alkoxide has a faster rate of hydrolysis.

[0125] 本发明的涂布组合物采用通常实施的涂布法将涂膜成膜,然后制成涂膜。 The coating composition [0125] The present invention employs a coating film forming method is usually implemented, then formed coating film. 作为涂布法,可采用例如浸涂法、旋涂法、喷涂法、刷毛涂布法、辊转印法、丝网印刷法、喷墨法或胶版印刷法等。 The coating method may be used such as dip coating, spin coating, spray coating, brush coating, roller transfer method, a screen printing method, an inkjet method or a flexo printing method. 其中特别优选适合于图案印刷的喷墨法和胶版印刷法。 Wherein particularly preferably suitable for inkjet printing method and the pattern offset printing method.

[0126] 〈涂膜〉 [0126] <coating film>

[0127] 本发明的涂膜用上述本发明的涂布组合物形成。 [0127] The present invention is a coating film-forming coating composition of the present invention. 而且,可以作为触摸屏的电极保护膜用于下述本发明的触摸屏。 Further, as an electrode protective film for a touch panel of the touch panel of the present invention described below.

[0128] 本发明的涂膜是含有作为无机物的金属氧化物作为成分的涂膜,与由丙烯酸材料等有机材料构成的涂膜相比,硬度更高,具有更高的强度。 [0128] The present invention is a coating film containing metal oxide coating film of an inorganic substance as a component, compared to the film made of organic material such as acrylic material, higher hardness, higher strength. 即,机械强度优异,保护透明电极不受手指等的多次按压的影响。 I.e., excellent mechanical strength, protective transparent electrode finger or the like from the influence of multiple presses.

[0129] 用由有机材料构成的膜构成触摸屏的情况下,例如配置于触摸屏的电极间的层间绝缘膜由丙烯酸材料等有机材料构成的情况下,本发明的涂膜特别有效。 [0129] The case where the touch panel constituting a film made of an organic material, such as a case where an interlayer disposed between the electrodes of the touch screen an insulating film made of organic material such as acrylic material, coating film of the present invention is particularly effective. 即,即使在由有机材料构成的膜上形成本发明的涂膜,也能进行成分组成的选择,以使其不会因为与有机膜在热伸缩性方面的差异而发生开裂。 That is, even if the coating film formed from an organic film material of the present invention, the chemical composition can be selected so that it will not differ in the organic film of the thermal cracking occurs scalability.

[0130] 本发明的涂膜也适合作为下述触摸屏的电极的保护膜。 [0130] a coating film according to the present invention are also suitable as an electrode below the touch screen protection film. 即,藉由该涂膜,可抑制能观察到透明电极图案的现象(电极图案可见现象)。 That is, by the film, can be suppressed observed phenomenon (the phenomenon of electrode patterns visible) of the transparent electrode pattern. 因此,藉由用该涂膜形成的触摸屏,能减少显示装置的显示性的下降。 Thus, by using the touch panel formed coating film, can reduce the deterioration in display of a display device.

[0131] 在触摸屏中观察到透明电极图案的原因在于,位于基板的操作区域内的透明电极图案的折射率与基板的折射率不同。 [0131] Cause transparent electrode pattern was observed in a touch screen comprising a substrate different from the refractive index of the transparent electrode pattern in the operating region of the substrate. 触摸屏的透明电极图案通常由作为无机金属氧化物的ΙΤ0(氧化铟锡(Indium Tin Oxide))构成。 The transparent electrode pattern of a touch screen usually consists ΙΤ0 an inorganic metal oxide (indium tin oxide (Indium Tin Oxide)). ΙΤ0的折射率为1.8~2.1左右。 ΙΤ0 refractive index is about 1.8 to 2.1. 另一方面,玻璃基板的折射率为1.4~1.5左右,因此与ΙΤ0的折射率有很大差异。 On the other hand, the refractive index of the glass substrate is about 1.4 to 1.5, and therefore differs significantly from the index of refraction ΙΤ0. 该折射率的差异使得在形成有透明电极图案的区域和未形成透明电极图案的区域之间产生光反射特性的差异。 This difference in refractive index region is formed such that a transparent electrode pattern is not formed and the reflection characteristic difference between the light generating region of the transparent electrode pattern. 即,伴随干涉的界面反射特性在形成有透明电极图案的区域和未形成透明电极图案的区域之间有差异,因而导致在画面显示时电极图案显眼的结果。 That is, as the interference of the interface reflection characteristic difference is formed between the region and the region of the transparent electrode pattern is not transparent electrode pattern is formed, thereby causing display screen results when the electrode pattern visible.

[0132] 于是,本发明人为了使透明电极图案不显眼而反复进行了认真研究,结果发现,有效的是在配置于基板上的透明电极图案上设置折射率和膜厚被控制在所希望的范围内的层。 [0132] Accordingly, the present invention in order to make inconspicuous the transparent electrode pattern is repeated extensive studies, found that it is effective to set the refractive index and the film thickness is controlled on a substrate disposed on the transparent electrode pattern desired layer is within the range. 具体而言,可知通过将透明电极图案的保护层的折射率和膜厚控制在最佳范围内,能抑制触摸屏中的透明电极图案不经意地被观察到的现象。 Specifically, it was found by the refractive index and thickness of the protective layer, the transparent electrode pattern is controlled in an optimum range, the phenomenon can be suppressed transparent electrode pattern of a touch screen inadvertently be observed.

[0133] 特别是欲抑制能观察到透明电极图案的现象的情况下,将本发明的涂膜的折射率控制在1.50~1.70的范围内、优选1.52~1.70的范围内。 [0133] For the case where particularly observed suppression to the transparent electrode pattern, the refractive index of the coating film of the present invention is controlled in the range of 1.50 to 1.70, preferably in the range of 1.52 to 1.70. 对于折射率的控制方法,除了如上所述控制涂布组合物的成分组成以外,也能通过成膜方法的控制来实现。 A method for controlling the refractive index, as described above in addition to the control content of the coating composition to composition, but also by controlling the film forming method to achieve.

[0134] 作为涂膜的形成方法,可例举应用胶版印刷等通常实施的涂布法将本发明的涂布组合物在触摸屏的电极上涂布成膜而制成涂膜的方法。 [0134] As a method for forming a coating film, or offset printing applications include coating methods generally embodiment of the present invention, the coating composition is coated on the deposition electrode is made of the touch screen coating method.
