Description
本發明關於三芳基甲烷化合物及含有該化合物而成之濾色器,該三芳基甲烷化合物例如於用作著色劑時,可提供即便持續長時間經受高溫下之熱歷程,色相變化亦較小之著色物。 The present invention relates to a triarylmethane compound and a color filter containing the compound. When the triarylmethane compound is used as a colorant, for example, it can provide a small change in hue even if it is subjected to a high temperature thermal history for a long time. Coloring matter.
液晶顯示裝置等之濾色器具有紅色像素部(R)、綠色像素部(G)及藍色像素部(B)。該等各像素部均為於基板上設置有分散有機顏料而成之合成樹脂之薄膜的結構,作為有機顏料,使用有紅、綠及藍各種顏色之有機顏料。 A color filter such as a liquid crystal display device includes a red pixel portion (R), a green pixel portion (G), and a blue pixel portion (B). Each of these pixel portions has a structure in which a thin film of a synthetic resin in which an organic pigment is dispersed is provided on a substrate. As the organic pigment, organic pigments of various colors of red, green, and blue are used.
作為用以形成該等像素部中之藍色像素部之藍色有機顏料,一般而言,使用ε型酞菁銅顏料(C.I.顏料藍15:6),為了調色,視需要向其中少量併用紫色有機顏料之二紫顏料(C.I.顏料紫23)。 As the blue organic pigment used to form the blue pixel portion of these pixel portions, generally, an ε-type copper phthalocyanine pigment (CI Pigment Blue 15: 6) is used, and a small amount thereof is used in combination as needed for color adjustment. Purple Organic Pigment 2 Violet pigment (CI Pigment Violet 23).
製作濾色器時之有機顏料具有與習知之通用用途完全不同之特性,具體而言,具有使液晶顯示裝置等之顯示畫面變得更明亮(高亮度化)等要求。然而,若與ε型酞菁銅顏料併用二紫顏料,則無法達成高亮度,故而特別是對於用於藍色像素部(B)之有機顏料尤其要求高亮度化。 The organic pigments used in the production of color filters have completely different characteristics from conventional general-purpose applications, and specifically, have requirements such as making a display screen of a liquid crystal display device or the like brighter (higher brightness). However, if used in combination with ε-type copper phthalocyanine pigment Since a purple pigment cannot achieve high brightness, the organic pigment used for the blue pixel portion (B) is particularly required to have high brightness.
為了應對此種高亮度化,最近正研究將於亮度之方面較ε型酞菁銅顏料優異之C.I.顏料藍1之類的三芳基甲烷顏料用於濾色器之藍色像素部(專利文獻1~3)。 In order to cope with such high brightness, research is currently underway to use a triarylmethane pigment such as CI Pigment Blue 1 which is superior in brightness to ε-type copper phthalocyanine pigments for the blue pixel portion of a color filter (Patent Document 1) ~ 3).
作為該C.I.顏料藍1,著名的是以下化學結構之BASF公司之Fanal Color(FANAL BLUE D6340、FANAL BLUE D6390),C.I.顏料藍1係將作為鹼性三芳基甲烷染料之維多利亞純藍BO利用磷鉬酸或磷鎢鉬酸之類的雜多酸進行色澱化而獲得。關於以此方式獲得之C.I.顏料藍1,陽離子之相對離子A-為科金型(Keggin type)PMoxW12-xO40。 As the CI Pigment Blue 1, the well-known Fanal Color (FANAL BLUE D6340, FANAL BLUE D6390) of the following chemical structure of BASF Company, CI Pigment Blue 1 series will be used as the basic triaryl methane dye of Victoria Pure Blue BO using phosphorus molybdenum Heteropolyacids such as acids or phosphotungstic molybdic acids are obtained by lake formation. Obtained on CI Pigment Blue 1 of this embodiment, the cationic counterions A - is Cocking type (Keggin type) PMo x W 12 -x O 40.
[其中,通式(IX)中,An-為科金型磷鎢鉬酸根陰離子或磷鉬酸根陰離子;n表示任意之自然數] [Wherein, in the general formula (IX), A n- is a Coking-type phosphotungstate molybdate anion or a phosphomolybdate anion; n represents an arbitrary natural number]
又,最近亦研究將並非是上述三芳基甲烷顏料之三芳基甲烷染料用於濾色器之藍色像素部(專利文獻4~5)。關於該等三芳基甲烷染料,作為陰離子,認為可使用鹵化物陰離子、四苯基硼之類的硼陰離子、有機羧酸根陰離子、無機硫酸根陰離子、無機磷酸根陰離子、脂肪族磺酸陰離子、芳香族磺酸陰離子、與蒽醌色素或酞菁色素或靛藍色素對應之磺 酸陰離子等。 In addition, recently, it has been studied to use a triarylmethane dye other than the triarylmethane pigment for a blue pixel portion of a color filter (Patent Documents 4 to 5). Regarding these triarylmethane dyes, as anions, it is thought that a halide anion, a boron anion such as tetraphenylboron, an organic carboxylate anion, an inorganic sulfate anion, an inorganic phosphate anion, an aliphatic sulfonic acid anion, and an aromatic can be used. Sulfonic acid anion, sulfonic acid corresponding to anthraquinone pigment or phthalocyanine pigment or indigo pigment Acid anions, etc.
進而,亦正研究將由金屬酞菁磺酸與三芳基甲烷陽離子之鹽所構成之染料作為三芳基甲烷染料,而用於濾色器之藍色像素部(專利文獻6)。 Furthermore, the use of a dye composed of a metal phthalocyanine sulfonic acid and a salt of a triarylmethane cation as a triarylmethane dye is also being studied for a blue pixel portion of a color filter (Patent Document 6).
又,亦正研究將由藉由特定結構之三芳基甲烷與特定結構之雜多金屬氧酸根陰離子(hetero polyoxometalate anion)形成之鹽所構成之化合物用於濾色器之藍色像素部(專利文獻7、8)。 Also, a blue pixel portion of a color filter is being studied using a compound composed of a salt formed by a triarylmethane with a specific structure and a hetero polyoxometalate anion with a specific structure (Patent Document 7) ,8).
進而,亦正研究將由藉由經二聚化之三芳基甲烷與陰離子形成之鹽所構成之化合物亦同樣地用於濾色器藍色像素部(專利文獻9)。 Furthermore, a compound composed of a salt formed by dimerized triarylmethane and an anion is also being studied for a blue filter portion of a color filter in the same manner (Patent Document 9).
然而,實際情況為:於將該等習知之三芳基甲烷顏料或三芳基甲烷染料用於濾色器之藍色像素部之製備之情形時,會因持續長時間地經受光線時或製作濾色器時的熱歷程,而使像素之色相顯著降低,仍然無法持續長時間維持令人滿意之亮度,就耐光性、耐熱性之方面而言不充分。 However, the actual situation is that when the conventional triarylmethane pigment or triarylmethane dye is used in the preparation of the blue pixel portion of a color filter, it will be subjected to light for a long period of time or a color filter will be produced. The thermal history of the device significantly reduces the hue of the pixel, and still cannot maintain satisfactory brightness for a long time, which is insufficient in terms of light resistance and heat resistance.

又,本發明於如下方面優異:可如上述通式(I)般藉由使連結基Z連結於特定之部位而自由地變更對耐熱性有效果之A部而進行合成,從而可進一步提昇耐熱性。例如,若合成上述中間體1或上述中間體2,則可容易地變更A部。進而,藉由變更A部,顏色會變化,因此可調整成所需顏色。 In addition, the present invention is excellent in that it can be synthesized by freely changing the A part having an effect on heat resistance by connecting the linking group Z to a specific portion as in the above-mentioned general formula (I), so that the heat resistance can be further improved. Sex. For example, if the intermediate 1 or the intermediate 2 is synthesized, the A part can be easily changed. Furthermore, since the color is changed by changing part A, it can be adjusted to a desired color.
