Synthetic example 1

[0173] In the flask equipped with condenser tube and stirrer, add 2.5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of ethylene glycol monomethyl ether acetate, continue Add 15 parts by mass of methacrylic acid, 10 parts by mass of ω-carboxy dicaprolactone monoacrylate, 15 parts by mass of N-phenylmaleimide, 33 parts by mass of 2-ethylhexyl methacrylate, styrene 12 parts by mass, 15 parts by mass of glycerin monomethacrylate and 5.0 parts by mass of α-methylstyrene dimer (chain transfer agent), after ventilating with nitrogen, the temperature of the reaction solution was raised to 80°C under slow stirring , maintaining the temperature for 3 hours to carry out polymerization. Then, the reaction solution was heated up to 100°C, 0.5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) was added, and the polymerization was continued for 1 hour to obtain a resin solution (solid content concentration=30 mass %). The obtained resin had Mw=14000 an...

[0175] Preparation of radiation-sensitive composition

[0176] 400 parts by mass of pigment dispersion liquid (A-1), 200 parts by mass of resin solution (B-1) as (B) alkali-soluble resin, 60 parts by mass of dipentaerythritol hexaacrylate as (C) polyfunctional monomer , 6 parts by mass of 2,4-diethylthioxanthone, ethyl ketone as (D) radiation-sensitive polymerization initiator, 1-[9-ethyl-6-(2-methylbenzoyl)-9H -carbazol-3-yl]-, 1-(O-acetyl oxime) (manufactured by Chiba Special Tei 1 Chemical Karls, trade name IRGACURE OX02) 5 parts by mass, 2,2'-bis(2-chlorobenzene base)-4,4',5,5'-tetraphenyl-1,2'-diimidazole 2 mass parts and 2-mercaptobenzothiazole 2 mass parts, and propylene glycol monomethyl ether acetate as solvent They were mixed so that the solid content concentration became 20.0%, and a liquid composition (G1) was prepared.

[0177] The liquid composition (G1) was evaluated in the following procedure. The evaluation results are listed in Table 1.

Embodiment 2～6 and comparative example 1～5

[0185] In Example 1, except having replaced the kind of pigment dispersion liquid as shown in Table 1, it carried out similarly to Example 1, and prepared liquid composition (G2)-(G11).

[0186] Then, it evaluated similarly to Example 1 except having used liquid composition (G2)-(G11) instead of liquid composition (G1), respectively. The evaluation results are listed in Table 1.

[0187] Table 1

[0188]

[0189] It can be seen from Table 1 that the radiation-sensitive composition containing C.I. Pigment Green 58 and a solvent with 2 acetoxy groups can form green pixels with high brightness and contrast, and the contrast will not decrease with time. On the contrary, when using a solvent having 1 acetoxy group (Comparative Example 1), and when using a solvent having 3 acetoxy groups (Comparative Example 2), compared with when using a solvent having 2 acetoxy groups , low contrast.

Abstract

The invention relates to a coloring radioactive composition, a colorant fluid dispersion, a color filter and a colorful LCD component. The invention provides green pixel that can form high ration between lightness and contrast, and the contrast will not drop down following pass of time. The coloring radioactive composition comprises a colorant (A), a alkalis soluble resin (B), a polyfunctional monomer (C) and a coloring radioactive initiator of polymerization (D) and a solvent (E), characterized in that the colorant (A) contains C.I. everbright fast pigment green 58, and the solvent (E) contains two acetoxyl groups.

Description

technical field [0001] The present invention relates to a colored radiation-sensitive composition, a colorant dispersion, a color filter and a color liquid crystal display element, more specifically, to a transmissive or reflective color liquid crystal display device, a color camera tube element, an organic EL display element, Radiation-sensitive composition for forming colored layer suitable for color filter used in electronic paper, color filter having colored layer formed using said radiation-sensitive composition, and color liquid crystal display having said color filter element. Background technique [0002] As a method of forming a color filter using a colored radiation-sensitive composition, it is known to form a coating film of a colored radiation-sensitive composition on a substrate or a substrate on which a desired pattern-shaped light-shielding layer is formed in advance, by means of a color filter having a predetermined pattern. A method in which a photomask is ...
