For the green pixel, a pigment composition containing a polyhalogenated phthalocyanine pigment is known as a material which can provide a color filter having a wide luminance and a wide color reproduction range (see, for example, Patent Document 3). However, the green pixel formed by using the pigment composition containing the polyhalogenated phthalocyanine pigment has a problem that the solvent resistance is remarkably higher than that of C.I. Pigment Green 7 and C.I. Pigment Green 36 which have been conventionally used. Due to the above background, there is an urgent need to develop a radiation-sensitive composition capable of forming a green pixel having high luminance and excellent solvent resistance.

It is a coating film of 2.5 / / m. Then, after cooling these substrates to room temperature, using a high-pressure mercury lamp, with a photomask, the exposure amount of 2000 J / m 2 The coating film was exposed to radiation having wavelengths of 365 nm, 405 nm, and 436 nm. Then, these substrates were sprayed at a developing pressure of 1 kgf/cm 2 (nozzle diameter of 1 mm) for 1 minute at 23 ° C of 0.04% by weight of potassium hydroxide. The developing solution composed of the aqueous solution was subjected to rinsing and development, and then baked at 220 ° C for 30 minutes to form a green dot pattern of 200×200 ym -32 to 201015220 on the substrate. The obtained dot pattern was observed under an optical microscope, and the unexposed portion was observed. No development residue was identified on the glass substrate. The evaluation was 〇. Some development residues were identified, and the evaluation was △. The severe development residue was identified and evaluated as X. Further, the substrate on which the dot pattern was formed was immersed in N-methylpyrrolidone at 60 ° C for 10, 20, 30, and 40 minutes, and as a result, the dot pattern after immersion was retained and the impregnated N-methylpyrrolidone was completely When there was no coloring, it was evaluated as φ 〇, and although the dot pattern remained after immersion, when N-methylpyrrolidone was immersed after some immersion, it was evaluated as Δ, and when immersed, a dot pattern peeled off from the substrate was observed while being immersed. When N-methylpyrrolidone was colored, it was evaluated as X. Evaluation of chromaticity characteristics was carried out by applying a liquid composition (G-1) on a soda-lime glass substrate having a Si〇2 film which prevents sodium ions from eluting on a surface by a spin coater, and then performing on a hot plate at 90 °C. Prebaking was carried out for 4 minutes to form three coating films having different film thicknesses. For the obtained dot pattern, a color analyzer (MCPD 2000 manufactured by Otsuka Electronics Co., Ltd.) was used, and the chromaticity coordinates X(X, y) and stimuli in the CIE color system were measured by a C light source in a 2 degree field of view ( Y). From the measurement results, the chromaticity coordinates 値X and 値(Y) at a certain chromaticity coordinate 値y are obtained. The evaluation results are shown in Table 2. The larger Y値, the higher the light transmittance (brightness). Examples 2 to 18 and Comparative Examples 1 to 1 In the first embodiment, a liquid composition (G) was prepared in the same manner as in Example 1 except that the type and amount of the components contained were replaced by those shown in Table 1. One 2) ~ (G- 28). -33-201015220 Then, evaluation was carried out in the same manner as in Example 1 except that the liquid compositions (G-2) to (G-28) were used instead of the liquid composition (G-1). The evaluation results are shown in Table 2.
