Problems solved by technology
The colored layer formed in this way has the following problems: during development, residue or scum is likely to be generated on the substrate of the unexposed part or on the light-shielding layer, and the adhesion of the colored layer formed on the exposed part to the substrate or the light-shielding layer is insufficient. Furthermore, the coating film properties of the colored layer that is post-baked after development are poor
However, with conventionally known colored radiation-sensitive compositions, if the amount of exposure is reduced, the pattern will be chipped or undercut, or the pattern will be easily peeled off from the substrate due to insufficient adhesion with the substrate. Good pattern shape of pixels and black matrix at the same time in takt time

Embodiment
[0246] Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to the following examples.
[0247] In the following examples, the polystyrene conversion weight average molecular weight (Mw) is used to use the GPC column (G2000HXL2, G3000HXL1 and G4000HXL1 in series) produced by Toray Co., Ltd., and the elution solvent is tetrahydrofuran, and the flow rate is 0.1 ml It was measured by gel permeation chromatography (GPC) using monodisperse polystyrene as a standard under conditions of a column temperature of 40° C. per minute and a column temperature.
[0248] Synthesis example of styrene epoxy resin
Synthetic example 1
[0250] In a flask equipped with a condenser tube and a stirrer, dissolve 40.0 g of p-vinylbenzyl glycidyl ether, 27.0 g of N-phenylmaleimide, and 17.0 g of styrene in 300 g of propylene glycol monomethyl ether acetate 16.0 g of benzyl methacrylate, 4.0 g of 2,2'- azobisisobutyronitrile and 6.0 g of α-methylstyrene dimer were further added, and nitrogen purge was carried out for 15 minutes. After nitrogen purging, it heated at 80 degreeC, stirring a reaction tank, and it was made to react for 5 hours, and the solution containing 25 weight% of styrene epoxy resin [A-1] was obtained. The polystyrene conversion weight average molecular weight (Mw) of this styrene epoxy resin [A-1] was 6000.
Synthetic example 2～8
[0252] The types and usage amounts of the monomers and the usage amounts of 2,2'-azobisisobutyronitrile and α-methylstyrene dimer are shown in Table 1, except that it was carried out in the same manner as Synthesis Example 1, Solutions containing 25% by weight of styrene epoxy resins [A-2] to [A-8] were obtained, respectively. It should be noted that the usage amounts of each component in Table 1 are all by weight (g).
[0253] Table 1 shows the polystyrene-equivalent weight average molecular weight (Mw) of the styrene epoxy resin obtained in each synthesis example.

Abstract
The invention relates to a radiation sensitive composition, a color filter and a liquid crystal display element. The radiation sensitive composition comprises (A) a colorant, (B) an alkaline-soluble resin, (C) a multi-functional monomer and (D) a photopolymerization initiator, characterized in that the radiation sensitive composition is used for forming a coloring layer, and (B) the alkaline-soluble resin has a structure represented by the formula (B-1): where R1, R2 and R3 independently represent a hydrogen atom or a alkyl having 1 to 10 carbon atoms, X is a univalent group having acryloyl and methacryloyl or vinyl or 1-methyl vinyl, Y is a bivalent organic group, and h is an integral of 1 to 5.
Description
technical field [0001] The present invention relates to a radiation-sensitive composition for forming colored layers used in color liquid crystal display devices and kinescope elements, color filters and black matrices, and color liquid crystal display elements. More specifically, it relates to a radiation-sensitive composition for forming a colored layer that can easily produce a colored layer that is excellent in properties such as coating film properties and is excellent in developability, and a color filter having a colored layer formed from the composition. A light sheet and a black matrix composed of a colored layer formed from the composition, and a color liquid crystal display element including the color filter or the black matrix. Background technique [0002] Conventionally, when a radiation-sensitive composition is used to form a color filter or a black matrix, the radiation-sensitive composition is coated on a substrate or a substrate on which a light-shielding l...
