Embodiment

[0338] Hereinafter, examples are given to further specifically describe the present invention. However, the present invention is not limited to the following examples. The following "parts" and "%" are mass standards unless otherwise indicated.

[0339] Mw and Mn of the resins obtained in the following synthesis examples were measured by the following gel permeation chromatography (GPC).

[0340] Device: GPC-101 (manufactured by Showa Denko Co., Ltd.)

[0341] Column: Combined use of GPC-KF-801, GPC-KF-802, GPC-KF-803 and GPC-KF-804

[0342] Elution solvent: THF with 0.5% phosphoric acid

[0343] The dispersant, polyfunctional monomer, photopolymerization initiator, and curing agent used in this example are as follows.

Synthetic example 1

[0362] Add 3 parts of 2,2'-azobisisobutyronitrile, 200 parts of propylene glycol monomethyl ether acetate into a flask equipped with a condenser tube and a stirrer, then add 15 parts of methacrylic acid, 20 parts of N-phenylmethane Laimide, 10 parts of styrene, 55 parts of benzyl methacrylate, and 5 parts of 2,4-diphenyl-4-methyl-1-pentene (trade name Nofma-MSD manufactured by NOF Co., Ltd. ) as a molecular weight regulator, nitrogen substitution. Thereafter, the mixture was stirred slowly to raise the temperature of the reaction solution to 80° C., and the temperature was kept at this temperature for 5 hours to perform polymerization, thereby obtaining a resin solution. This resin is referred to as "alkali-soluble resin (c-1)". The polystyrene-equivalent weight-average molecular weight measured by gel permeation chromatography of this alkali-soluble resin was 11,000, and Mw / Mn was 2.6.

Synthetic example 2

[0364]Add 3 parts of 2,2'-azobisisobutyronitrile, 200 parts of propylene glycol monomethyl ether acetate, followed by 15 parts of methacrylic acid, 85 parts of benzyl methacrylate in a flask equipped with a condenser and a stirrer , and 5 parts of 2,4-diphenyl-4-methyl-1-pentene (trade name Novoma-MSD manufactured by NOF Co., Ltd.) as a molecular weight regulator, nitrogen substitution. Thereafter, the mixture was stirred slowly to raise the temperature of the reaction solution to 80° C., and the temperature was kept at this temperature for 5 hours to perform polymerization, thereby obtaining a resin solution. This resin is referred to as "alkali-soluble resin (c-2)". The alkali-soluble resin had a polystyrene-equivalent weight-average molecular weight of 13,000 as measured by gel permeation chromatography, and Mw / Mn of 28.

Abstract

The invention relates to a radiation ray sensitive composition, a colour filter and a liquid crystal display used to form a coloured coat. The radiation ray sensitive composition used to form a coloured coat is characterized in that the composition contains (A) a pigment, (B) dispersant of which at least one of acid value and ammonia value is more than 0, (C) alkali soluble resins, (D) a multifunctional monomer, (E) optical polymerization initiator and (F) a polymer with repeated unit content of oxacyclobutane more than 70%. Even at a post-baking temperature of less than 200 DEG C, radiation ray sensitive composition used to form a coloured coat can form pixels and a black matrixes which are good in acid resistance to wide range of solvent and have good tightness with base plates.

Description

technical field [0001] The present invention relates to a radiation-sensitive composition for forming a colored layer, a color filter, and a liquid crystal display element, and more specifically, to a radiation-sensitive composition for forming a colored layer for use in transmission-type or A color filter used in a reflective liquid crystal display device, a color pickup tube element, etc.; a color filter having a colored layer formed using the radiation-sensitive composition; and a liquid crystal display element including the color filter. Background technique [0002] As a method of forming a color filter using a radiation-sensitive composition for forming a colored layer, it is known to form a pigment-dispersed type for forming a colored layer on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance. The coating film of the radiation-sensitive composition is irradiated with radiation through a photomask having a predetermin...
