Pigment Red 177。該顏料可 藉由機械處理容易進行微細化，另外，由於經微細化的顔 料可較爲容易分散，故爲提高對比時極爲有用（例如參照曰 本國特開平10-148712號公報）。然而，使用該顏料之彩色 濾光片’由於該顔料具有分光特性，故對於亮度之提高受 到限制》 最近，使用二酮吡咯并吡咯系紅色顏料之C.I. Pigment Red 25 4取代蒽醌系紅色顏料。由於該顏料與C.l Pigment Red 1 77相比時，於600nm附近之透過光譜移至短波長側， 背景光之紅色亮線的吸收變得更少，故可提高明度（例如參 照日本特開平11-231516號公報、特開2002-328217號公 1325879 形成紅色著色膜’且有關該紅色著色膜係使用F10光源測 定XYZ表色系之色度時，X爲0.64時之色度y在0.30〜0.35 的範圍內，且明度Y値爲23以上較佳。明度Y値以愈高 値愈佳，惟實質上其上限値約爲28。 另外，於本發明之彩色濾光片用紅色著色組成物中， 對上述3種顔料之合計重量而言佔有30〜75重量％該二酮 吡咯并吡咯系紅色顏料，佔有20〜60重量％蒽醌系紅色顔 料’佔有5〜3 0重量％偶氮系黃色顏料較佳。 此外，以上述二酮吡咯并吡咯系紅色顏料爲 C.I. Pigment Red 254,上述蒽醌系紅色顏料爲C.I. Pigment Red 177，上述偶氮系黃色顏料爲c.I. Pigment Yellow 150較 佳。 〔發明效果〕 本發明之彩色濾光片用紅色著色組成物，可形成明度 及對比性高的紅色濾光片部分。 而且，藉由使用本發明之彩色濾光片，可使液晶顯示 裝置高亮度化 '高對比化。 〔爲實施發明之最佳形態〕 首先，說明有關本發明之彩色濾光片用紅色著色組成 物。 本發明之彩色濾光片用紅色著色組成物，含有由透明 樹脂、其前驅體或此等之混合物所成的著色料載體、與紅 色著色料’且視其所需可含有分散助劑、光聚合起始劑、 增感劑 '有機溶劑，水平劑等。 1325879 本發明之彩色濾光片用紅色著色組成物中所含有的紅 色者色料’至少含有二酮吡咯并吡咯系紅色顔料、蒽醌系 紅色顏料、及偶氮系黃色顔料之3種顏料（以下稱該3種顏 料爲「3種特定顔料」）。 本發明之彩色濾光片用紅色著色組成物，由於高明度 與高對比性兩立，故至少配合3種特定顏料。總之，僅藉 由單獨使用有利於提高明度之二酮吡咯并吡咯系紅色顏 料’無法得到充分的對比性，故倂用有利於高對比化的蒽 醒系紅色顏料。然而，爲得充分的對比性時配合蒽醌系紅 色顏料時’由於背景光之紅色亮線吸收變多，故明度降低。 因此’爲維持高明度時，另外配合有利於高對比性之偶氮 系黃色顏料。 於本發明之彩色濾光片用紅色著色組成物中，添加3 種特定顏料外，爲調整色度時可含有喹吖啶酮系、茈系、 P比蒽-8，1 6 -二酮系、偶氮系等之紅色顏料、或異吲哚滿系、 喹酞酮系、蒽醌系等之黄色顏料》 本發明之彩色濾光片用紅色著色組成物，就明度與色 相之平衡性而言使用本發明之彩色濾光片用紅色著色組成 物以形成紅色著色膜，有關該紅色著色膜於使用F10光源 測定XYZ表色系之色度時，X爲0.6 4時之色度y調整爲 0.30〜0.35之範圍，且明度Y値調整爲23以上較佳。色度 y小於0.30時，透過率變低且明度降低。另外，色度y大 於0.35時，由於色相帶有黃味，無法形成色再現性之高顯 示。而且，明度Y値小於2 3時，液晶顯示裝置之亮度降低’ 1325879 不爲企求。 而且’ F10光源爲JIS規定的典型之螢光燈，具有接近 一般液晶顯示裝置之背景燈所使用的3波長範圍發光形螢 光燈之分光分布。 二酮吡咯并吡咯系紅色顏料，例如 C.I. Pigment Orange 71、C.I. Pigment Red 254、255、264 等。其中，由 於C.I. Pigment Red 2 5 4具有優異的耐光性、耐熱性、透明 性、著色力，故更適合使用。 蒽醌系紅色顏料，例如C.I. Pigment Red 177，由於其 優異的耐光性·耐熱性或透明性、著色力，故更適合使用》 偶氮系黃色顏料，例如C.I. Pigment Yellow 1、3、10、 12、13、14、17、55、81、83、93，94、95、97、150、154、 166、167、180 等。其中，由於 C.I. Pigment Yellow 150 具有優異的耐光性•耐熱性或透明性、著色力，故更適合 使用。 而且，於本發明之彩色濾光片用紅色著色組成物中， 偶氮系黃色顏料使用於調色，一般而言爲彩色濾光片用途 時大多使用 C.I. Pigment Yellow 139等之異吲哚滿系顏 料、C.I. Pigment Yellow 138等之喹酞酮系顏料等。然而， 僅使用此等顏料時，由於顏料之粒子形狀或具有分子構造 引起的去極化性（de-polarization)，故不利於筒對比化。 於本發明之彩色濾光片用紅色著色組成物中’對上述 3種特定顏料之合計重量而言，以二酮吡咯并吡咯系紅色 顔料佔有30〜75重量％，蒽醍系紅色顏料佔有20〜60重 -10- 1325879 量％，偶氮系黃色顏料佔有5〜3 0重量％較佳，另外以二酮 批咯并吡咯系紅色顏料佔有3 5〜6 5重量％，蒽醌系紅色顏 料佔有30〜50重量％，偶氮系黃色顏料佔有5〜25重量％ 更佳。二酮吡咯并吡咯系紅色顏料之比例小於3 〇重量％時 無法得到充分的明度’大於75重量％時無法得到充分的對 比性。此外，蒽醌系紅色顏料之比例小於2 0重量％時無法 得到充分的對比性’大於6 0重量％時無法得到充分的明 度。而且，偶氮系黃色顏料之比例小於5重量％時無法實 現充分的明度提高效果，大於30重量％時由於色相過於帶 有黃味，故色再現性惡化。 如上所述，於本發明之紅色著色料中，除添加3種特 定顏料外’可含有其他顏料。3種特定顏料以佔有紅色著 色料之合計重量的8 0 %〜1 〇 〇 %較佳。 本發明之彩色濾光片用紅色著色組成物中所含的3種 特定顏料，爲實現彩色濾光片之高明度化、高對比化時， 平均一次粒徑必須在10〜50nm之範圍內。顏料之平均一次 粒徑，可藉由透過型電子顯微鏡觀察測定。3種特定顏料 之平均一次粒徑大於5 Onm時，彩色濾光片之明度或對比性 降低’小於1 Onm時，顏料分散非常困難，無法確保作爲著 色組成物之流動性。結果，彩色濾光片之明度或對比性惡 化。 總之，本發明之彩色濾光片用紅色著色組成物中所含 的紅色著色料，除3種特定顏料外含有其他顏料時，其他 顏料以具有10〜50nm之平均一次粒徑較佳。 -11- 1325879 使顏料之一次粒徑變小的方法，有使顏料機械粉碎的 方法（稱爲磨碎法），使溶解於良溶劑的顔料投入貧溶劑 中’使企求的一次粒徑之顏料被析出的方法（稱爲析出 法），以及於顏料合成時製造具有企求的一次粒徑之顔料的 方法（稱爲合成析出法）等。可視使用的顏料之合成法或化 學性質等而定，選擇有關各種顔料之適當方法予以進行。 下述中說明有關各方法。 磨碎法係爲使顏料使用球磨、砂磨或混練機等，使氯 化鈉等水溶性無機鹽等之磨碎劑及不會溶解磨碎劑之水溶 性有機溶劑同時機械性混練（以下將該工程稱爲鹽磨法 (salt milling))後，水洗除去磨碎劑與有機溶劑，且藉由乾 燥製得企求比表面積的顏料之方法。惟藉由鹽磨處理時顏 料會結晶成長，故於處理時上述水溶性有機溶劑中至少添 加部分溶解的固成份樹脂或下述之分散助劑，可有效地防 止結晶成長。 有關顏料與磨碎劑（水溶性無機鹽）之比例，磨碎劑之 比例增多時顏料之微細化效率變佳，惟顏料之處理量變少 時生產性降低。一般而言’對1重量份顏料而言磨碎劑使 用1〜30重量份，較佳者爲2〜20重量份。 此外，水溶性有機溶劑係爲使顏料與磨碎劑（水溶性無 機鹽）均勻固化時所添加者’視顏料與磨碎劑之配合比例而 定，通常使用相當於顏料之50〜300重量％之量 更詳細說明有關磨碎法時，在顔料與磨碎劑（水溶性無 機鹽）之混合物中加入少量的水溶性有機溶劑作爲濕潤 -12- 1325879 劑’以混練機等強烈混練後，使該混合物投入水中，且以 商速混合機攪拌形成漿料。然後，藉由使該漿料過濾、水 洗、乾燥，製得企求的一次粒徑之顏料。 析出法係爲使顏料溶解於適當的良溶劑後，與貧溶劑 混合，使企求的一次粒徑之顏料析出的方法，可視溶劑之 種類或量、析出溫度、析出速度等而定，控制一次粒徑之 大小。一般而言，由於顏料不易溶解於溶劑中，可使用的 溶劑有限，例如濃硫酸、聚磷酸、氯磺酸等之強酸性溶劑 或液體銨、甲基化鈉之二甲基甲醯胺溶液等的鹼性溶劑 等，係爲已知。 析出法之典型例’爲使酸性溶劑中溶解有顏料之溶液 注入其他的溶劑中，進行再析出，製得微細粒子之酸性漿 料化（acid pasting)法。就成本而言，一般於工業上使用將 硫酸溶液注入水中的方法。硫酸濃度沒有特別的限制，以 95〜100重量％較佳。對顏料而言硫酸之使用量，沒有特別 的限制，惟硫酸之量愈少時所得的溶液之黏度愈高、處理 性不佳。反之，硫酸之量過多時顔料之處理效率降低。因 此’對1份顔料而言以使用3〜10重量份之硫酸較佳。而 且，顏料不一定必須完全溶解。顏料溶解時之溫度以〇〜 5 〇°C較佳，小於0°C之溫度時硫酸恐會凍結、且溶解度亦會 降低。顔料溶解時之溫度過高時，容易引起副反應。注入 硫酸之水的溫度以1〜60°C較佳，大於60 °C之溫度時開始注 入時因硫酸之溶解熱而沸騰，作業上極爲危險。小於1 °C之 溫度時，溶液會有凍結的情形。注入所需的時間，對1份 -13- 1325879 顏料而言以〇·1〜30分鐘較佳。 顏料之一次粒徑的控制，可藉由選擇組合酸性漿料化 法等之析出法與鹽磨法等之磨碎法的方法，可考慮顏料之 整粒程度進行’另外，就可確保所得顏料之流動性，故更 佳。 於鹽磨時或酸性漿料化時，爲防止伴隨控制—次粒徑 時顏料之凝聚情形時，亦可倂用下述之色素衍生物或樹脂 型分散劑、界面活性劑等之分散助劑。而且，藉由使一次 粒徑之控制以2種以上之顏料共存的形態進行，可使單獨 使用時不易分散的顏料形成安定的分散體。 合成析出法係爲使顏料合成時同時使企求的一次粒徑 之顏料析出的方法。然而，使生成的微細化顏料自溶劑中 取出時，由於顏料粒子不會凝聚成大的二次粒子時不易進 行一般分離法之過濾，故該方法通常使用在容易引起二次 凝聚的水系中所合成的偶氮系等之顔料。 此外’控制顏料之一次粒徑的方法，藉由使顏料以高 速的砂磨等進行長時間分散時（使顔料乾式粉碎、即乾式硏 磨法），可使顏料之一次粒徑變小的同時被分散。 本發明之彩色濾光片用紅色著色組成物中所含的著色 料載體，係爲使含有3種特定顏料之紅色著色料分散者， 由透明樹脂、其前驅體或此等之混合物所構成。透明樹脂 係爲在可視光範圍之400〜700nm全波長範圍中透過率爲 80%以上（較佳者爲95 %以上）之樹脂。透明樹脂包含熱可塑 性樹脂、熱硬化性樹脂、及活性能量線硬化性樹脂，其前 -14- 1325879 驅體包含藉由活性能量線照射硬化、生成透明樹脂之單體 或低聚物，此等可單獨使用或2種以上混合使用。 著色料載體對著色組成物中之紅色著色料之合計量爲 100重量份而言爲30〜700重量份，較佳者爲60〜450重 量份》而且，使用透明樹脂與其前驅體之混合物作爲著色 料載體時，透明樹脂對著色組成物中之紅色著色料的合計 量爲100重量份而言使用20〜400重量份，較佳者爲50〜 2 5 0重量份。此外，透明樹脂之前驅體對著色組成物中之 紅色著色料的合計量爲100重量份而言使用10〜3 0 0重量 份，較佳者爲1〇〜200重量份》 熱可塑性樹脂例如丁縮醛樹脂、苯乙烯-馬來酸共聚 物、氯化聚乙烯、氯化聚丙烯、聚氯化乙烯基、氯化乙烯[Technical Field] The present invention relates to a red coloring composition for a color filter used when forming a filter portion constituting a color filter used for a liquid crystal display device and a solid-state imaging device. A color filter obtained by coloring the composition with a red color filter and a liquid crystal display device having the same. [Prior Art] In recent years, the evaluation of a liquid crystal display device, which is called a thin type of space saving or lightweight, and power saving, has recently been rapidly promoted for television use. In the liquid crystal display device for televisions, the performance such as brightness and contrast is required to be improved, and the color filter constituting the member of the liquid crystal display device is more desired to have higher brightness and higher contrast. Conventionally, the coloring material constituting the red filter portion of the color filter has been C.I. Pigment Red 177 which is a lanthanide red pigment. The pigment can be easily refined by mechanical treatment, and the finely divided pigment can be easily dispersed. Therefore, it is extremely useful for improving the contrast (for example, see Japanese Patent Application Laid-Open No. Hei 10-148712). However, the color filter using the pigment has a limitation on the improvement of brightness because the pigment has spectral characteristics. Recently, C.I. Pigment Red 25 4 using a diketopyrrolopyrrole red pigment was used instead of the lanthanide red pigment. When the pigment is compared with Cl Pigment Red 1 77, the transmission spectrum near 600 nm shifts to the short wavelength side, and the absorption of the red bright line of the background light becomes less, so that the brightness can be improved (for example, refer to Japanese Patent Laid-Open No. 11- In the case of measuring the chromaticity of the XYZ color system using the F10 light source, the chromaticity y of X is 0.60 to 0.35 when the red coloring film is used to measure the chromaticity of the XYZ color system using the F10 light source. In the range, the brightness Y値 is preferably 23 or more. The higher the brightness Y値, the better, but the upper limit is substantially 28. In addition, in the red coloring composition of the color filter of the present invention, The total weight of the above three pigments accounts for 30 to 75% by weight of the diketopyrrolopyrrole red pigment, and 20 to 60% by weight of the ruthenium red pigment occupies 5 to 30% by weight of the azo yellow pigment. Further, the above diketopyrrolopyrrole red pigment is CI Pigment Red 254, the above lanthanide red pigment is CI Pigment Red 177, and the above azo yellow pigment is preferably cI Pigment Yellow 150. [Effect of the invention] this The color filter of the bright color is colored with a red coloring composition to form a red filter portion having high brightness and contrast. Moreover, by using the color filter of the present invention, the liquid crystal display device can be made highly brightened. [Best Mode for Carrying Out the Invention] First, a red coloring composition for a color filter according to the present invention will be described. The coloring filter of the present invention uses a red colored composition containing a transparent resin, a precursor thereof or the like. The color carrier of the mixture and the red coloring material 'and may contain a dispersing aid, a photopolymerization initiator, a sensitizer' organic solvent, a leveling agent, etc. as desired. 1325879 Color filter of the present invention The red coloring matter contained in the red coloring composition of the sheet contains at least three pigments of a diketopyrrolopyrrole red pigment, an anthraquinone red pigment, and an azo yellow pigment (hereinafter referred to as the three pigments) "3 kinds of specific pigments"). The color filter of the present invention uses a red coloring composition, and since it has two high-definition and high contrast properties, at least three kinds of specific pigments are blended. In short, only The diketopyrrolopyrrole red pigment which is used to improve the brightness alone cannot be sufficiently contrasted, so that the red pigment which is advantageous for high contrast is used. However, in order to obtain sufficient contrast, the ruthenium is used. When the red pigment is used, the red light absorption of the background light is increased, so the brightness is lowered. Therefore, in order to maintain the high brightness, an azo yellow pigment which is advantageous for high contrast is additionally blended. In the red coloring composition, three kinds of specific pigments may be added, and in order to adjust the chromaticity, a red color such as a quinacridone type, an anthraquinone type, a P ratio 蒽-8, a 16-diketone type or an azo type may be contained. Pigment, or yellow pigment such as isoindane, quinophthalone, or fluorene. The color filter of the present invention uses a red colored composition, and the color filter of the present invention is used in terms of the balance between lightness and hue. The light sheet is colored in red to form a red colored film, and when the chromaticity of the XYZ color system is measured using the F10 light source, the chromaticity y is adjusted to a range of 0.30 to 0.35 when X is 0.6 4 , and Brightness Y値 is adjusted to 23 or more is preferred. When the chromaticity y is less than 0.30, the transmittance is lowered and the brightness is lowered. Further, when the chromaticity y is larger than 0.35, since the hue has a yellowish taste, high display of color reproducibility cannot be formed. Further, when the brightness Y 値 is less than 2 3 , the brightness of the liquid crystal display device is lowered by '1325879. Further, the 'F10 light source is a typical fluorescent lamp specified by JIS, and has a spectral distribution of a three-wavelength range fluorescent lamp which is used near a backlight of a general liquid crystal display device. A diketopyrrolopyrrole red pigment such as C.I. Pigment Orange 71, C.I. Pigment Red 254, 255, 264, and the like. Among them, C.I. Pigment Red 254 is more suitable for use because of its excellent light resistance, heat resistance, transparency, and coloring power. Lanthanide red pigments, such as CI Pigment Red 177, are more suitable for use because of their excellent light fastness, heat resistance, transparency, and tinting strength. For example, azo yellow pigments such as CI Pigment Yellow 1, 3, 10, 12 13, 14, 14, 55, 81, 83, 93, 94, 95, 97, 150, 154, 166, 167, 180, and the like. Among them, C.I. Pigment Yellow 150 is more suitable for use because of its excellent light resistance, heat resistance, transparency, and coloring power. Further, in the red coloring composition for a color filter of the present invention, an azo yellow pigment is used for coloring, and in general, a color filter is used, and a CI Pigment Yellow 139 or the like is often used. A pigment, a quinophthalone pigment such as CI Pigment Yellow 138, or the like. However, when only such pigments are used, the contrast of the cylinder is disadvantageous due to the particle shape of the pigment or the de-polarization caused by the molecular structure. In the red colored composition of the color filter of the present invention, 'the total weight of the above three specific pigments is 30 to 75% by weight of the diketopyrrolopyrrole red pigment, and the lanthanide red pigment is 20%. ～60重量-10- 1325879% by volume, azo yellow pigment occupies 5 to 30% by weight, and diketone-b-pyrrolopyrene red pigment occupies 3 5 to 65% by weight, lanthanide red pigment It accounts for 30 to 50% by weight, and the azo yellow pigment accounts for 5 to 25% by weight. When the proportion of the diketopyrrolopyrrole red pigment is less than 3% by weight, sufficient lightness cannot be obtained. When it is more than 75% by weight, sufficient contrast cannot be obtained. Further, when the proportion of the lanthanide red pigment is less than 20% by weight, sufficient contrast cannot be obtained. When it is more than 60% by weight, sufficient brightness cannot be obtained. Further, when the proportion of the azo yellow pigment is less than 5% by weight, a sufficient brightness improving effect cannot be obtained, and when it is more than 30% by weight, the hue is excessively yellowish, so that the color reproducibility is deteriorated. As described above, in the red coloring material of the present invention, other pigments may be contained in addition to the addition of three specific pigments. It is preferable that the three specific pigments occupy 80% to 1 〇 〇 % of the total weight of the red coloring materials. In the color filter of the present invention, the three specific pigments contained in the red colored composition are required to have a uniform primary particle diameter of 10 to 50 nm in order to achieve high definition and high contrast of the color filter. The average primary particle size of the pigment can be determined by observation through a transmission electron microscope. When the average primary particle diameter of the three specific pigments is more than 5 Onm, the brightness or contrast of the color filter is lowered. When the average density is less than 1 Onm, the pigment dispersion is extremely difficult, and the fluidity as a colored composition cannot be ensured. As a result, the brightness or contrast of the color filter deteriorates. In other words, in the color filter of the present invention, when the red coloring matter contained in the red colored composition contains other pigments in addition to the three specific pigments, the other pigments preferably have an average primary particle diameter of 10 to 50 nm. -11- 1325879 A method for reducing the primary particle size of a pigment, a method of mechanically pulverizing a pigment (referred to as a grinding method), and a pigment dissolved in a good solvent is introduced into a poor solvent. A method of precipitation (referred to as a precipitation method), and a method of producing a pigment having a primary particle diameter (hereinafter referred to as a synthetic precipitation method) at the time of pigment synthesis. Depending on the synthesis method or chemical properties of the pigment to be used, an appropriate method for selecting various pigments may be selected. The respective methods are described below. The grinding method is to use a ball mill, a sanding or a kneading machine, and the like, and a grinding agent such as a water-soluble inorganic salt such as sodium chloride or a water-soluble organic solvent which does not dissolve the grinding agent is mechanically kneaded (hereinafter, This process is called salt milling, and the method of removing the grounding agent from the organic solvent by water washing and drying to obtain a pigment having a specific surface area is obtained. However, since the pigment crystallizes and grows by the salt milling treatment, at least a partially dissolved solid resin or a dispersing aid described below is added to the water-soluble organic solvent at the time of the treatment, and the crystal growth can be effectively prevented. When the ratio of the pigment to the grounding agent (water-soluble inorganic salt) is increased, the ratio of the grinding agent is increased, and the fineness of the pigment is improved, but the productivity is lowered when the amount of the pigment is reduced. In general, the abrasive is used in an amount of 1 to 30 parts by weight, preferably 2 to 20 parts by weight, per part by weight of the pigment. In addition, the water-soluble organic solvent is a ratio of the pigment to the grinding agent added when the pigment and the grinding agent (water-soluble inorganic salt) are uniformly cured, and usually 50 to 300% by weight of the pigment is used. In more detail, when the grinding method is used, a small amount of a water-soluble organic solvent is added as a wetting agent to the mixture of the pigment and the grounding agent (water-soluble inorganic salt) as a wetting agent -12-1325879. The mixture was placed in water and stirred by a commercial mixer to form a slurry. Then, the slurry was filtered, washed with water, and dried to obtain a desired primary particle size pigment. The precipitation method is a method in which a pigment is dissolved in a suitable good solvent, and then mixed with a poor solvent to precipitate a pigment having a primary particle size, depending on the type or amount of the solvent, the precipitation temperature, the precipitation rate, and the like, and the primary particle is controlled. The size of the path. In general, since the pigment is not easily dissolved in a solvent, a solvent which can be used is limited, for example, a strong acidic solvent such as concentrated sulfuric acid, polyphosphoric acid or chlorosulfonic acid, or a liquid ammonium, a methylated methyl dimethylformamide solution, or the like. Alkaline solvents and the like are known. A typical example of the precipitation method is an acid pasting method in which fine particles are re-precipitated by injecting a solution in which a pigment is dissolved in an acidic solvent into another solvent. In terms of cost, a method of injecting a sulfuric acid solution into water is generally used industrially. The sulfuric acid concentration is not particularly limited, and is preferably 95 to 100% by weight. The amount of sulfuric acid used for the pigment is not particularly limited, but the less the amount of sulfuric acid, the higher the viscosity of the resulting solution and the poor handleability. Conversely, when the amount of sulfuric acid is too large, the treatment efficiency of the pigment is lowered. Therefore, it is preferred to use 3 to 10 parts by weight of sulfuric acid for 1 part of the pigment. Moreover, the pigment does not have to be completely dissolved. The temperature at which the pigment is dissolved is preferably 〇 5 5 ° C. When the temperature is less than 0 ° C, the sulfuric acid may freeze and the solubility may decrease. When the temperature at which the pigment is dissolved is too high, side reactions are likely to occur. The temperature of the water to be injected with sulfuric acid is preferably from 1 to 60 ° C, and when it is injected at a temperature of more than 60 ° C, it is boiled by the heat of dissolution of sulfuric acid, which is extremely dangerous in operation. At temperatures below 1 °C, the solution will freeze. The time required for the injection is preferably from 1 to 30 minutes for 1 part -13 to 1325879 pigment. The control of the primary particle size of the pigment can be carried out by selecting a method such as a precipitation method such as an acidic slurrying method or a grinding method such as a salt milling method, and the degree of granulation of the pigment can be considered. The liquidity is better. In the case of salt milling or acid slurrying, in order to prevent aggregation of the pigment accompanying the control-secondary particle size, the following pigment derivative, resin type dispersing agent, dispersing agent such as a surfactant may be used. . Further, by controlling the primary particle diameter to be carried out in such a manner that two or more kinds of pigments coexist, it is possible to form a stable dispersion of the pigment which is not easily dispersed when used alone. The synthetic precipitation method is a method of simultaneously depositing a desired primary particle size pigment when the pigment is synthesized. However, when the produced fine pigment is taken out from the solvent, since the pigment particles are not aggregated into large secondary particles, it is difficult to perform filtration by a general separation method, and therefore, the method is generally used in a water system which is liable to cause secondary aggregation. A synthetic azo-based pigment. In addition, when the method of controlling the primary particle diameter of the pigment is carried out by long-term dispersion of the pigment by high-speed sanding or the like (dry pulverization of the pigment, that is, dry honing), the primary particle diameter of the pigment can be made small while Being dispersed. The coloring material carrier contained in the red colored composition of the color filter of the present invention is composed of a transparent resin, a precursor thereof or a mixture thereof, in which a red coloring material containing three kinds of specific pigments is dispersed. The transparent resin is a resin having a transmittance of 80% or more (preferably 95% or more) in the entire wavelength range of 400 to 700 nm in the visible light range. The transparent resin contains a thermoplastic resin, a thermosetting resin, and an active energy ray-curable resin, and the precursor-14- 1325879 includes a monomer or oligomer which is cured by irradiation with an active energy ray to form a transparent resin. They may be used singly or in combination of two or more. The coloring material carrier is 30 to 700 parts by weight, preferably 60 to 450 parts by weight, based on 100 parts by weight of the red coloring matter in the coloring composition. Further, a mixture of a transparent resin and its precursor is used as a coloring. In the case of the carrier, the transparent resin is used in an amount of 20 to 400 parts by weight, preferably 50 to 250 parts by weight, based on 100 parts by weight of the total amount of the red coloring matter in the coloring composition. Further, the transparent resin precursor is used in an amount of 10 to 300 parts by weight, preferably 1 to 200 parts by weight, based on 100 parts by weight of the total amount of the red coloring matter in the coloring composition.

The manufacturing method of the filter has the advantages of low cost and excellent mass productivity. In addition, by the development of printing technology, it is possible to perform printing with a fine pattern having high dimensional accuracy and smoothness. In order to carry out printing, the composition of the ink on the printing plate or on the felt is not dried and hardened. In addition, it is extremely important to control the fluidity of the ink on the printing machine, and it is also possible to use a dispersing agent or a body. The pigment is adjusted for ink viscosity. When the color filter portions are formed by lithography, the prepared coloring composition as the solvent developing type or the alkali developing type colored photoresist is spray-coated or spin-coated or slit-coated. A coating method such as roll coating is applied to a transparent substrate at a dry film thickness of 2 to ΙΟμηη. When the coating film is dried, a vacuum dryer, a convection oven, an IR oven, a hot plate or the like can also be used. Ultraviolet exposure is carried out by providing a mask having a predetermined pattern on the dried film as it is required to be in contact with or in contact with the film. Then, the color filter may be formed by immersing in a solvent or an alkali developing solution or spraying the developing solution by spraying, removing the uncured portion and forming a desired pattern, and repeating the same operation for the other colors. Further, in order to promote the polymerization of the colored photoresist, heating may be carried out as needed. By lithography, a highly accurate color filter can be produced by the above printing method.

For the development processing method, a rinsing development method, a spray imaging method, a dipping -25 - 1325879 development method, a smelting (liquid) development method, or the like can be used. Further, in order to improve the ultraviolet exposure sensitivity, the colored photoresist may be coated and dried, and then coated with a water-soluble or alkali-soluble resin such as polyvinyl alcohol or a water-soluble acrylic resin to form a polymer to prevent polymerization inhibition by oxygen. After the film is exposed to ultraviolet light. The color filter of the present invention can be produced by an electrofusion method, a transfer method or the like in addition to the above method. Further, the electrofusion method is a method of producing a color filter by electrophoresis of a colloidal particle by electrophoresis of a colloidal particle by electrophoresis of a colloidal particle on a transparent conductive film. Further, the transfer method is a method in which a filter portion is formed in advance on the surface of the peelable transfer substrate or the transfer body, and the filter portion is transferred to a desired transparent substrate. When the black matrix is formed before the color filter portions are formed on the transparent substrate or the reflective substrate, the contrast of the liquid crystal display panel can be further improved. As the black substrate, a multilayer film of a complex or a road/chromium oxide, an inorganic film such as tantalum nitride, or a resin film in which an opacifier is dispersed can be used. Further, a thin film transistor (TFT) is formed in advance on the above transparent substrate or reflective substrate, and then a filter portion is formed. By forming the filter portion on the TFT substrate, the aperture ratio of the liquid crystal display panel can be improved and the brightness can be improved. On the color filter of the present invention, a surface coating film or a columnar spacer, a transparent conductive film, a liquid crystal alignment film or the like is formed as needed.

The particle diameter is represented by the average enthalpy as the average primary particle diameter. Further, when the particle shape is not spherical, the long diameter and the short diameter are measured, and the enthalpy obtained by (long diameter + short diameter)/2 is used as the particle diameter. [Chromaticity and Contrast] After the red coloring composition was cured, the chromaticity X was 〇.64 (F10 light source), and it was applied to a glass substrate by spin coating, and dried at 70 ° C for 20 minutes. Use an ultra-high pressure mercury lamp to expose the UV light. Then, the substrate was heat-treated at 230 ° C for 1 hour to obtain a red colored film. With respect to the red colored film, the chromaticity (Y, X, y) of the F10 light source was measured using a microscopic spectrophotometer ("OSP-SP100" manufactured by Olympus Optics Co., Ltd.). Further, a polarizing plate is superposed on both sides of the substrate on which the red colored film is formed, and the polarizing plate is obtained by comparing the luminance (Lp) in parallel with the luminance (Lc) at the time of orthogonality, and using Lp/Lc as a contrast. .

如表3所示，使用本發明實施例1〜3之著色組成物所 形成的紅色著色膜中，X爲0.64時之色度y在0.30〜0.35 之範圍，且明度Y値爲23以上。另外，對比性亦可達到高 値。 此外，使用比較例1之著色組成物所形成的紅色著色 膜中，明度Y値大爲降低成23。此係因藉由使用RP 179取 代PR2 5 4，其較PR254更可使600nm附近之透過光譜在長 波長側，背景光之紅色亮線之吸收變大之故。而且，比較 例2〜4之紅色著色膜中，對比性爲低値。比較例2及3中 使用平均一次粒徑大於本發明之規定範圍的上限値（5 Onm) 之紅色顏料，另外，比較例4中由於使用PY138作爲黃色 顔料，各去極化作用顯著，對比性爲低値。 【圖面之簡單說明】 【第1圖】係爲具備本發明彩色濾光片之液晶顯示裝 置例的簡略截面圖 -37 - 1325879As shown in Table 3, in the red colored film formed by using the coloring compositions of Examples 1 to 3 of the present invention, the chromaticity y when X is 0.64 is in the range of 0.30 to 0.35, and the brightness Y値 is 23 or more. In addition, the contrast can also be achieved. Further, in the red colored film formed by using the color composition of Comparative Example 1, the brightness Y値 was greatly reduced to 23. This is because the PR2 5 4 is substituted by using RP 179, which makes the transmission spectrum near 600 nm on the long wavelength side and the absorption of the red bright line of the background light larger than that of the PR254. Further, in the red colored films of Comparative Examples 2 to 4, the contrast was low. In Comparative Examples 2 and 3, a red pigment having an average primary particle diameter larger than the upper limit 値 (5 Onm) of the predetermined range of the present invention was used, and in Comparative Example 4, since PY138 was used as a yellow pigment, the respective depolarization effects were remarkable, and the contrast was remarkable. It is low.
