Description of the invention: [Technical test label 3] The present invention relates to a rubber coating for printing and a method for manufacturing the same. C ^tr ] 1 5 BACKGROUND OF THE INVENTION This invention relates to a blanket for printing. In particular, a blanket for printing a fine color pattern such as a color filter (hereinafter referred to as CF) φ pattern for a liquid crystal display (hereinafter referred to as LCD), or an electrode pattern for a plasma display panel (hereinafter referred to as PDP), and a manufacturing method thereof method. In recent years, the use of offset printing to implement thin line patterns has been extensively studied. For example, printing a CF pattern of an LCD on a glass substrate by using a lithography method, or printing an electrode pattern for a PDP, or printing various circuit patterns on various plastic films is widely reviewed. The reason for investigating such a printing method in the field is, for example, advantageous in terms of cost as the process is simplified and large equipment is not required. However, when the fine patterning is performed by this printing method, Lu j does not lower the performance level such as the line shape as compared with the conventional method. Further, when the fine line patterning is performed by such a printing method, it is required to achieve cost reduction. 2〇+版印刷疋 The j method of transferring the pattern to the final printed matter using a blanket is a rubber material which is placed on the soil material composed of the composite of the base fabric and the rubber as the surface rubber. And grind the surface and open it. Printing of the current method has been widely used in newspaper printing and commercial printing. However, for the thin line patterning, the conventional rubber cloth is difficult to apply for various reasons due to its rough surface and poor ink transfer rate. Therefore, in order to improve this situation, development of the surface property of the blanket and the material constituting the rubber were started. In order to perform the fine line patterning well using a blanket, it is necessary to make the blanket have a rough edge of 5 degrees which is as close as possible to the surface roughness of the body to be printed. Further, the surface rubber is particularly suitable for sililcone rubber because of its excellent release property, and can have a very high ink transfer rate as compared with other organic rubbers. The surface roughness of the rubber mat is very important when performing fine line patterning. When the surface roughness of the blanket is large, the line will be chaotic. In addition, the adhesion between the blanket and the ink material will increase and the pinhole will occur. Generally, as of now, when the fine line is patterned, the surface roughness of the blanket should be as small as possible within the range that can be processed. However, it is difficult to control the surface roughness of the blanket to be small, and if the surface roughness is to be small, it is accompanied by the fact that various other members necessary for manufacturing the blanket become expensive products and are manufactured. The program will be complicated, etc., resulting in cost increases. When the surface roughness of the blanket is too small, it is known that the printing plate or the adhesion between the printed body and the blanket is enhanced by the printing condition, and the transfer rate is lowered or the printing quality is improved. The situation of decline. So far, about the blanket used in the thin line patterning
表面相'糙度及其製造方法已有各種提案。例如，為了PDP 的電核基板印刷，已有建議使用具有算術平均粗糙度Ra在 0.1n 111以上不滿20nm，十點平均粗糙度Rz在O.lnm以上不滿 200948625 5 ❹ 10 15 e 20 l〇〇nm的表面橡膠之橡皮布者（特開2〇〇519〇969號公報）。 另外，為了高分子電致發光材料的印刷，以使用具十點平 均粗糙度以下，算術平均粗糙度2nm以下的 表面橡膠層之橡皮布為佳（特開2005-310411號公報）。另 外，有建議在模具内平行配置基材與平滑構件，並對其注 入橡膠原料使之硬化，藉剝除平滑部以施行表面橡膠的成 形之橡皮布製造方法(特開平8-112981號公報）。另外，有建 礅在水平架台上貼合基材，在該基材上倒入液態橡膠原料 使其進行自調平（self-leveling)直接依原狀硬化 ，藉以施行 表面橡膠成形的橡皮布製造方法（特開2003_136856號公 報）。 而’因為特開2005-190969號公報及特開 2005-310411號公報僅限定表面平滑度，所以會發生依被印 刷體的狀態而更為要求平滑性的情形，而即使是這些文獻 中所規定的表面平滑度也有不充分的情况。另外，特開平 8-112981號公報有必須細心注意不要產生薄膜表面的髒 污、損傷等’在作業效率方面上的問題。另外，特開 2003-136856號公報即使得到與基材表面的平滑度相關聯 的表面性狀，也無法製造與被印刷體的表面性狀有關聯性 的表面性狀之橡皮布。 C發明内容3 發明概要 本發明是無論被印刷體的表面性狀如何，都想要獲得 具有最適合其表面性狀的表面性狀之橡皮布，並且做成橡 5 200948625 皮布表面橡膠的算術平均粗糙度相對於被印刷體表面的算 術平均粗糙度Ra(p)，具有〇.〇5x Ra(p)〜4.5x Ra(p)之值的算 術平均粗糙度的印刷用橡皮布。亦即，橡皮布表面橡膠的 算術平均粗糙度以被印刷體表面的算術平均粗糙度尺畸卩) 5 為基準’其值訂在〇.〇5xRa(p)〜4.5xRa(p)的範圍。另外， 該種印刷用橡皮布的製造方法是，準備好相對於被印刷體 的算術平均粗糙度Ra(p)具有0_ 1 xRa(p)〜3 xRa(p)的範圍之 算術平均粗糙度的基板(模子；），在該基板表面注入液態橡 膠’之後依原狀使其硬化。然後，在該已硬化的橡膠表面 10 塗布黏著劑形成黏著劑層，在該黏著劑層之上貼合橡皮布 的基材。接著’於表面橡膠層硬化之後’自上述基板(模子) 剝掉橡皮布，製造印刷用橡皮布。 依據本發明所得到的橡皮布，因為與被印刷體的表面 性狀有關係，所以橡皮布的表面性狀優異，同時還可以廉 15價且簡單的製造。另外，藉使用此橡皮布，可以在被印刷 體上無晝線混沌且精確度極高地印刷微細的細線圖案。另 外’可以得到無針孔的印刷體。其結果，即使使用液晶顯 不器用彩色濾光片也不會産生色斑。另外，因為沒有針孔， 故亦可做到不發生漏光。此外，如果利用此方法，則基板(模 20 子）的大型化亦可容易地達成。 圖式簡單說明 第1圖為本發明之一實施例的橡皮布之部份斷面。 第2圖為本發明之另一實施例的橡皮布之部份斷面。 第3(A)、（B)圖是使用本發明實施例的橡皮布對被 200948625 體轉印畫線圖案的狀態之概略性示意說明。 第4圖為實施例1之印刷體的畫線形狀之部份外觀的顯 示相片。 第5圖為比較例1之印刷體的畫線形狀之部份外觀的顯 5 示相片。 C實方方式]1 較佳實施例之詳細說明 本發明的橡皮布是相對於被印刷體表面的算術平均粗 糙度Ra(p)具有0.05 xRa(p)〜4.5 xRa(p)的算術平均粗糖度之 10 橡皮布。發明人研究了最適合用在細線圖案化之橡皮布的 表面粗糙度，發現該橡皮布的表面粗糙度可以透過用其與 被印刷體的關聯來決定的方式而予以最適化。並且，發現 藉使用該橡皮布來印刷具優異的畫線形狀之印刷物的結 果。此時之橡皮布表面粗糙度，被發現並不限於與被印刷 15 體的表面粗縫度相同，合適的是使用相對於被印刷體之表 面的算術平均粗糙度Ra(p)，具有從〇.〇5xRa(p)到4.5xRa(p) 之範圍之算術平均粗糙度Ra的橡皮布。 相對於被印刷體之表面的算術平均粗糖度，不滿 0.05xRa(p)時’會因印刷條件而導致轉印不良(部份畫線潼 20 亂）。另外，使用相對於被印刷體表面的算術平均粗糙度 Ra(p)，有超過4.5xRa(p)之值的大算術平均粗糙度的橡皮布 時，表面橡膠的表面粗糙度大，畫線湲亂。另外，發現油 墨和橡皮布的密著力增强，有生成針孔等的缺陷之情形。 發明人重複多次實驗’發現使用相對於被印刷體的表面粗 200948625 糙度Ra(p) ’具有0 〇5xRa(p)〜4 5xRa(p)的算術平均粗糙度 之橡皮布來印刷於前記被印刷體時，可使畫線形狀良好， 且無針孔等的缺陷。 另外，可知獲得該表面粗縫度之橡皮布的製造方法是 5使相對於被印刷體的算術平均粗糙度Ra(p)具有〇.lxRa(p) 〜3xRa(p)的算術平均粗糙度的構件(模子），保持接觸橡皮 布的表面橡膠原料的狀態直接使之硬化，然後將其剝掉以 施行表面橡膠之成形時，該橡皮布的算術平均粗糙度會成 為0_05xRa(p)〜4.5xRa(p)。 10 關於前記橡皮布及橡皮布製造用構件(模子），尤其以使 用相對於被印刷體表面的算術平均粗糙度Ra(p)，具有 O-lxRa(p)〜3xRa(p)的算術平均粗糙度之構件(模子）為佳。 較佳的是具有〇.2xRa(p)〜2xRa(p)的數值之算術平均粗糙 度的構件(模子）。 15 使被印刷體的表面粗縫度轉印到橡皮布之表面橡膠上 的方法是，透過在水平架台上水平貼合相對於被印刷體表 面的算術平均粗糙度Ra(p)具有從〇.lxRa⑻到3xRa⑻之表 面粗糙度的構件(模具材）’用各種方法將液態橡膠原料塗布 於其上，使之硬化，然後將黏著劑塗布到橡膠表面，貼合 20 橡皮布基材，再從模具材將其剝除以製造轉印了表面形狀 的橡皮布之方法是有效的。除此之外，也可以在模具内平 行配置橡皮布基材和被印刷體(模具材），在該橡皮布基材和 模具材之間注入液態橡膠原料，保持原狀使之硬化後從模 具材剝除，藉以製造橡皮布。無論被印刷體(模具材）的種類 200948625 可以製造的觀點上看’以不使用模具而用水平架 台之前述方法為佳。 第圖疋本發明之一例的橡皮布，由表面橡膠^與其下 :土材2λΕ成。基材12由表面橡膠η正下方的聚對苯二甲 5 S文乙一酯薄膜（p〇lyethylene terephthalate，以下稱 pet 薄 膜）m與壓縮層122和其下之最下層的聚醋布 123組成。基 材由、神搞布、尼龍布等公知的織布，或PE丁薄膜、聚 蔡甲酸乙—醇醋薄膜(以下稱pEN薄膜）、聚醯亞胺薄膜等 的各種塑料薄膜單體，或者這些織布和塑料薄膜及橡膠材 1〇料等的複合材料構成。合適的是在該基材部分的層中配置 3有獨立或連續氣泡的壓縮層。將該壓縮層導人基材中， 藉以防止印刷時產生凸起’並可期待提高印刷物的尺寸精 確度。 表面橡膠層可以使用丙烯腈一丁二烯、乙丙橡膠 15 (ethyleneProPylene rubber)、天然橡膠、石夕橡膠(silicon rubber) 等既存的橡膠材料。其中尤以石夕橡膠的橡膠表面之油墨轉 印率為優。該矽橡膠以使用易於轉印加工被印刷體(模子） 的表面形狀之液態原料為佳。 表面橡膠層的厚度以0.1到1mm為佳，較佳的是從0.3 20 到〇.8mm。表面橡膠層的厚度小於0.1mm時，下層基材的影 響也會反映在表面橡膠上，會在表面平坦性上產生問題。 表面橡膠層的厚度如果比1mm厚，橡皮布使用時會因為對 表面橡膠層發生溶劑溶脹導致表面橡膠層的體積變化加 大，結果就發生印刷精確度惡化的問題。 9 200948625 被印刷體的材質雖無特殊限制，但是玻璃基板被使用 在LCD的CF用或PDP的電極用等，作為施行細線圖案化的 基板是最廣受研究的。另外，各種塑料薄膜也成為電路圖 案化的對象，PET薄膜、PEN薄膜、聚醜亞胺薄膜等既存的 5 薄膜單體之外，可以使用在這些塑料薄膜上塗布丙烯酸樹 脂或聚酯樹脂，將表面做得平滑或提高油墨密著性的材料 等。 製造橡皮布時所使用的模具材宜為被印刷體本身，不 過’即使不是被印刷體本身’還是可以應用具備與被印刷 10 體同等的表面粗糙度的材料。這些模具材使用於橡皮布的 製造時’宜施以離型處理以增加其可使用次數。應用於離 型處理的材質可使用含氟材料、含矽材料的液態原料等材 料，通過浸塗、擦拭、喷塗等方法在模具材上均勻塗布。 藉使用該模具材，如前所述地實施橡皮布的表面橡膠之形 15 成，可以製造低成本且容易具備被印刷體所要求之表面粗 糙度的橡皮布。 第2圖為本發明另一實施例的橡皮布。在第2圖中，21 爲表面橡膠 TSE3453T(Momentive Performance MaterialsVarious proposals have been made for the surface phase 'roughness and its manufacturing method. For example, for the nuclear substrate printing of PDP, it has been proposed to use an arithmetic average roughness Ra of 0.1 n 111 or more and less than 20 nm, and a ten point average roughness Rz of more than 0.1 nm or less than 200948625 5 ❹ 10 15 e 20 l〇〇 The rubber of the surface rubber of nm (Japanese Patent Publication No. 2〇〇519〇969). In addition, a blanket having a surface rubber layer having an arithmetic mean roughness of 2 nm or less and having a ten-point average roughness or less and an arithmetic mean roughness of 2 nm or less is preferably used for the printing of the polymer electroluminescent material (JP-A-2005-310411). In addition, it is proposed to produce a blanket manufacturing method in which a base material and a smoothing member are arranged in parallel in a mold, and a rubber material is injected and hardened, and a smoothing portion is removed to perform surface rubber molding (JP-A No. 8-112981) . In addition, there is a method for manufacturing a blanket which is formed by laminating a substrate on a horizontal stand, pouring a liquid rubber material onto the substrate, and performing self-leveling to directly harden it as it is, thereby performing surface rubber forming. (Japanese Patent Laid-Open Publication No. 2003_136856). In addition, since the surface smoothness is limited only in the case of the publication, the smoothness is required depending on the state of the printed body, and even if it is specified in these documents, The surface smoothness is also insufficient. Further, Japanese Laid-Open Patent Publication No. Hei 8-112981 is required to pay careful attention to problems such as contamination of the surface of the film, damage, and the like. Further, in JP-A-2003-136856, even if a surface property associated with the smoothness of the surface of the substrate is obtained, it is not possible to produce a blanket having a surface property which is related to the surface properties of the substrate to be printed. C SUMMARY OF THE INVENTION 3 SUMMARY OF THE INVENTION The present invention is intended to obtain a blanket having a surface property most suitable for its surface properties regardless of the surface properties of the printed body, and to achieve the arithmetic mean roughness of the surface rubber of the rubber 5 200948625 A blanket for printing having an arithmetic mean roughness of a value of 〇.5x Ra(p) to 4.5x Ra(p) with respect to the arithmetic mean roughness Ra(p) of the surface of the object to be printed. That is, the arithmetic mean roughness of the rubber on the surface of the blanket is based on the arithmetic mean roughness of the surface of the printed body. 5 The value is set in the range of 〇.〇5xRa(p) to 4.5xRa(p). Moreover, the manufacturing method of the printing blanket is prepared to have an arithmetic mean roughness of a range of 0_1 x Ra(p) to 3 xRa(p) with respect to the arithmetic mean roughness Ra(p) of the to-be-printed body. The substrate (mold;) is hardened as it is after the liquid rubber is injected into the surface of the substrate. Then, an adhesive is applied to the hardened rubber surface 10 to form an adhesive layer, and a substrate of the blanket is attached to the adhesive layer. Then, after the surface rubber layer was hardened, the blanket was peeled off from the above substrate (mold) to produce a blanket for printing. The blanket obtained according to the present invention is excellent in the surface properties of the blanket because of its relationship with the surface properties of the object to be printed, and can be manufactured inexpensively and simply. Further, by using this blanket, it is possible to print fine fine line patterns on the printed body without chaos and chaos with high precision. In addition, a pinhole-free print can be obtained. As a result, no color spots are generated even if a color filter for a liquid crystal display is used. In addition, since there is no pinhole, it is possible to prevent light leakage. Further, if this method is used, the enlargement of the substrate (the mold 20) can be easily achieved. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a partial cross-sectional view of a blanket according to an embodiment of the present invention. Figure 2 is a partial cross-sectional view of a blanket of another embodiment of the present invention. Figs. 3(A) and (B) are schematic illustrations showing the state in which the line pattern is transferred by the 200948625 using the blanket of the embodiment of the present invention. Fig. 4 is a view showing a part of the appearance of the shape of the line of the printed body of the first embodiment. Fig. 5 is a photograph showing the appearance of a part of the shape of the line of the printed body of Comparative Example 1. C. The preferred embodiment of the present invention is a detailed description of the preferred embodiment of the present invention. The blanket of the present invention has an arithmetic mean roughness of 0.05 x Ra(p) to 4.5 xRa(p) with respect to the arithmetic mean roughness Ra(p) of the surface of the body to be printed. 10 of the blanket. The inventors studied the surface roughness of a blanket which is most suitable for use in fine line patterning, and found that the surface roughness of the blanket can be optimized by means of its association with the object to be printed. Further, it was found that the result of printing a printed matter having an excellent line shape by using the blanket was obtained. The surface roughness of the blanket at this time was found to be not limited to the same as the surface roughness of the surface to be printed, and it is suitable to use the arithmetic mean roughness Ra(p) with respect to the surface of the object to be printed, having A blanket of 算术5xRa(p) to an arithmetic mean roughness Ra in the range of 4.5xRa(p). With respect to the arithmetic mean coarse sugar content of the surface of the object to be printed, when it is less than 0.05xRa(p), the transfer may be poor due to the printing conditions (partial line 潼 20 chaos). Further, when a blanket having a large arithmetic mean roughness exceeding a value of 4.5×Ra(p) with respect to the arithmetic mean roughness Ra(p) of the surface of the object to be printed is used, the surface roughness of the surface rubber is large, and the line is drawn. Chaos. Further, it has been found that the adhesion between the ink and the blanket is enhanced, and there are cases where defects such as pinholes are generated. The inventors repeated a number of experiments to find that a blanket having a surface roughness of 200948625 roughness Ra(p) 'with an arithmetic mean roughness of 0 〇5xRa(p) 〜4 5xRa(p) was printed on the surface of the printed object. When the object is printed, the shape of the line can be made good, and there is no defect such as a pinhole. Further, it is understood that the method for producing the blanket having the rough surface degree is 5 such that the arithmetic mean roughness Ra(p) of the object to be printed has an arithmetic mean roughness of 〇.lxRa(p) to 3xRa(p). The member (mold) maintains the state of the rubber material on the surface of the blanket and hardens it, and then peels it off to form the surface rubber. The arithmetic mean roughness of the blanket becomes 0_05xRa(p)~4.5xRa. (p). 10 Regarding the pre-recorded blanket and the fabric manufacturing member (mold), in particular, using the arithmetic mean roughness Ra(p) with respect to the surface of the object to be printed, the arithmetic mean roughness of O-lxRa(p) to 3xRa(p) The component (mold) of degree is preferred. Preferred is a member (mold) having an arithmetic mean roughness of a value of 2.2xRa(p) 2 2xRa(p). 15 The method of transferring the rough surface of the printed body onto the surface rubber of the blanket is to have a radial average roughness Ra(p) with respect to the surface of the printed body by horizontally fitting on the horizontal gantry. The surface roughness component (mold material) of lxRa(8) to 3xRa(8) is applied to the liquid rubber material by various methods to harden it, and then the adhesive is applied to the rubber surface, and the 20 blanket substrate is bonded to the mold. The method of stripping the material to produce a blanket to which the surface shape is transferred is effective. In addition, a blanket substrate and a to-be-printed body (mold material) may be disposed in parallel in the mold, and a liquid rubber material may be injected between the blanket substrate and the mold material to maintain the original shape and harden the mold material. Stripping to make a blanket. Regardless of the type of printed body (mold material) 200948625, it is preferable to use the above-described method of using a horizontal stand without using a mold. The blanket of an example of the present invention is composed of a surface rubber and a soil material 2λ. The substrate 12 is composed of a polyethylene terephthalate film (hereinafter referred to as a pet film) m directly below the surface rubber η and a compression layer 122 and a lowermost layer of the polyester cloth 123. a known woven fabric such as a substrate, a god cloth, a nylon cloth, or a plastic film film such as a PE film, a poly-cabbard film (hereinafter referred to as a pEN film), a polyimide film, or the like, or These woven fabrics are composed of a composite material such as a plastic film and a rubber material. It is suitable to arrange 3 a compression layer having independent or continuous bubbles in the layer of the substrate portion. The compression layer is introduced into the substrate to prevent the occurrence of protrusions during printing, and it is expected to increase the dimensional accuracy of the printed matter. As the surface rubber layer, an existing rubber material such as acrylonitrile-butadiene, ethylene-Propylene rubber, natural rubber, or silicon rubber can be used. Among them, the rubber surface of the stone rubber of Shixi rubber is excellent. The tantalum rubber is preferably a liquid material which is easy to transfer and process the surface shape of the printed body (mold). The thickness of the surface rubber layer is preferably from 0.1 to 1 mm, preferably from 0.320 to 〇.8 mm. When the thickness of the surface rubber layer is less than 0.1 mm, the influence of the underlying substrate is also reflected on the surface rubber, which causes a problem in surface flatness. If the thickness of the surface rubber layer is thicker than 1 mm, the use of the blanket causes a change in the volume of the surface rubber layer due to solvent swelling of the surface rubber layer, and as a result, the printing accuracy is deteriorated. 9 200948625 The material of the printed material is not particularly limited, but the glass substrate is used for the CF or the PDP electrode of the LCD, and the substrate which is patterned by the thin line is the most widely studied. In addition, various plastic films are also the object of circuit patterning. In addition to the existing 5 film monomers such as PET film, PEN film, and poly-imide film, it is possible to apply an acrylic resin or a polyester resin to these plastic films. A material that is smooth on the surface or that improves ink adhesion. The mold material used in the production of the blanket is preferably the body itself, and it is possible to apply a material having the same surface roughness as that of the body 10 to be printed, even if it is not the body itself. These mold materials are used in the manufacture of blankets. The release treatment should be applied to increase the number of times they can be used. The material used for the release treatment can be uniformly coated on the mold material by dip coating, wiping, spraying or the like using a material such as a fluorine-containing material or a liquid material containing a ruthenium material. By using the mold material, the surface rubber of the blanket is formed as described above, and a blanket which is low in cost and easily has the surface roughness required for the printed body can be manufactured.
