Description

著色組成物、及著色阻劑組成物Coloring composition and coloring resist composition

本發明係關於一種著色組成物、及含有其之著色阻劑組成物。The present invention relates to a coloring composition and a coloring resist composition containing the same.

近年來，黑矩陣用著色組成物之用途涉及多個方面，例如，被用以於液晶或電漿等之平板顯示器中，於畫面之顯示區域內之著色圖案之間隙或顯示區域周邊部分之緣，又，於使用TFT之液晶顯示器中，於TFT之外光側等設置遮光膜（黑矩陣）。而且，發揮如下作用：於液晶顯示器中主要防止來自背光之漏光映現於畫面中，又，於電漿顯示器中主要防止因各色光之渾濁所引起之滲色映現於畫面中，而提高顯示特性（對比度及色純度）。In recent years, the use of coloring compositions for black matrices involves many aspects. For example, they are used in flat panel displays such as liquid crystal or plasma, in the gaps of colored patterns in the display area of the screen or the edges of the peripheral part of the display area. In addition, in a liquid crystal display using TFT, a light shielding film (black matrix) is provided on the light side of the TFT. Moreover, it plays the following role: in the liquid crystal display, the leakage of light from the backlight is mainly prevented from being reflected in the screen, and in the plasma display, the color bleeding caused by the turbidity of each color light is mainly prevented from being reflected in the screen, thereby improving the display characteristics ( Contrast and color purity).

例如，於用以將液晶顯示器之背光之白色光轉換為著色光之濾色器中，通常藉由在形成有黑矩陣之玻璃或塑膠片等透明基板表面依序以條紋狀或馬賽克狀等之圖案形成紅、綠、藍之不同色相之像素的方法來製造。For example, in a color filter used to convert the white light of the backlight of a liquid crystal display into colored light, it is usually done by sequentially forming stripes or mosaics on the surface of a transparent substrate such as glass or plastic sheet on which a black matrix is formed. The pattern is made by the method of forming pixels of different hues of red, green and blue.

又，於組合影像顯示裝置及位置輸入裝置而成之觸控面板中，亦同樣地利用形成有黑矩陣之濾色器作為遮光膜，迄今為止，一般隔著蓋玻璃形成於與感測器基板相反之側。但是，隨著對觸控面板之輕量化之要求提高，為了謀求更輕量化，正在開發一種於蓋玻璃之同一側同時形成遮光膜及觸控感測器之技術。In addition, in a touch panel formed by combining an image display device and a position input device, a color filter formed with a black matrix is also used as a light-shielding film. So far, it is generally formed on the sensor substrate via a cover glass. The opposite side. However, as the requirements for lighter weight of touch panels increase, in order to achieve lighter weight, a technology is being developed that simultaneously forms a light shielding film and a touch sensor on the same side of the cover glass.

例如，於專利文獻1中，揭示有一種技術，其係藉由在色間隔物形成用感光性著色組成物中，組合使用特定之顏料及碳黑作為著色劑，並且使碳黑之含有比率為特定範圍，而賦予遮蔽性等。For example, Patent Document 1 discloses a technique in which a specific pigment and carbon black are used in combination as a colorant in a photosensitive coloring composition for forming color spacers, and the content ratio of carbon black is A specific range is provided, and shielding properties are provided.

又，例如，於專利文獻2中，揭示有一種技術，其係藉由適當地組合光吸收特性不同之顏料種類，以確保紫外線區域與可見光區域之光吸收之平衡，而維持遮光性及液晶之電壓保持率。In addition, for example, Patent Document 2 discloses a technique that appropriately combines the types of pigments with different light absorption characteristics to ensure the balance of light absorption in the ultraviolet region and the visible light region, and maintain light-shielding properties and liquid crystal properties. Voltage retention rate.

然而，於構成影像顯示裝置之液晶層之黑矩陣等之著色組成物之耐溶劑性較低之情形時，會產生於像素圖案產生龜裂或缺損、或者著色成分自像素圖案溶出之問題。 於上述技術中，未針對耐溶劑性進行研究，期望開發出一種能夠獲得耐溶劑性優異之黑色阻劑圖案之黑矩陣用著色組成物。 [先前技術文獻] [專利文獻]However, when the solvent resistance of the coloring composition such as the black matrix of the liquid crystal layer constituting the image display device is low, the problem of cracks or defects in the pixel pattern or the elution of coloring components from the pixel pattern may occur. In the above technique, no research has been conducted on solvent resistance, and it is desired to develop a black matrix coloring composition capable of obtaining a black resist pattern with excellent solvent resistance.
