Embodiment

[0172] Hereinafter, although an Example demonstrates this invention in more detail, this invention is not limited to these Examples. In addition, in an Example, unless otherwise indicated, a part means a mass part.

[0173] The softening point, epoxy equivalent, acid value, and NMR were measured on the following conditions.

[0174] 1) Epoxy equivalent: measured by a method based on JIS K7236:2001.

[0175] 2) Softening point: Measured by a method based on JIS K7234:1986.

[0176] 3) Acid value: Measured by a method based on JIS K0070:1992.

[0177] 4) 13C-NMR:

[0178] Measuring device: VARIAN NMR system 400MHz

[0179] Solvent: deuterated chloroform

Synthetic example 1-1

[0181] Put 168 parts by mass (1.0 moles) of 2,6-bis(hydroxymethyl)-p-cresol and 1008 parts by mass (7.0 moles) of α-naphthol in a glass container with a thermometer, a reflux cooler, and a stirrer, and add formaldehyde Using 1,500 mL of isobutyl ketone as a solvent, the mixture was stirred at room temperature under a nitrogen atmosphere. 1.7 parts by mass of p-toluenesulfonic acid (1.0 mass % relative to 2,6-bis(hydroxymethyl)-p-cresol) was slowly added while paying attention to heat generation so that the liquid temperature would not exceed 50°C. After the addition, it was heated to 50° C. on an oil bath, and after reacting for 2 hours, 500 mL of methyl isobutyl ketone was added, transferred to a separatory funnel, and washed with water. After washing with water until the washing water became neutral, the organic layer was concentrated under reduced pressure to obtain 370 parts by mass of a pale yellow viscous substance. The softening temperature (JIS K2425 ring and ball met...

[0186] Put 168 parts by mass (1.0 moles) of 2,6-bis(hydroxymethyl)-p-cresol and 1008 parts by mass (7.0 moles) of β-naphthol in a glass container with a thermometer, a reflux cooler, and a stirrer, and add formaldehyde Using 1,500 mL of isobutyl ketone as a solvent, the mixture was stirred at room temperature under a nitrogen atmosphere. 1.7 parts by mass of p-toluenesulfonic acid (1.0 mass % relative to 2,6-bis(hydroxymethyl)-p-cresol) was slowly added while paying attention to heat generation so that the liquid temperature would not exceed 50°C. After the addition, it was heated to 80° C. on an oil bath, and after reacting for 2 hours, 500 mL of methyl isobutyl ketone was added, transferred to a separatory funnel, and washed with water. After washing with water until the washing water became neutral, the organic layer was concentrated under reduced pressure to obtain 371 parts by mass of a yellow solid. The softening temperature (JIS K2425 ring and ball method) was 113° C.,...

Abstract

The invention relates to active radiation hardenable resin composition, and a spacer and / or a color filter protective layer for a display element using the same. The objective of the invention lies in providing the spacer and the color filter protective layer for the display element, wherein the spacer or the protective layer is good in heat resistant transparency, flatness, flexibility, and tenacity. The active radiation hardenable resin composition for spacer or the protective layer contains a reactive polybasic carboxylic acid compound (A), a reactive compound (B) different from the reactive polybasic carboxylic acid compound (A), a photopolymerization initiator (C), and an organic solvent (D). The reactive polybasic carboxylic acid compound (A) enables the reaction products of epoxy resin with a compound (B) and a compound (C) to further react with polybasic anhydride (D) to obtain the reactive polybasic carboxylic acid compound (A), wherein one molecule of the reactive polybasic carboxylic acid compound (A) at least contains two or more epoxy groups, one molecule of the compound (B) contains one or more polymerizable olefinic unsaturated groups and one or more carboxy groups, and one molecule of the compound (C) at least contains two or more hydroxide radicals and one or more carboxy groups.

Description

technical field [0001] The present invention relates to an active energy ray curable resin composition, a colored spacer for display elements, and / or a black matrix. Background technique [0002] A color liquid crystal display (LCD) adopts a structure in which a color filter is opposed to an electrode substrate such as a TFT substrate, a gap of about 1 μm to about 10 μm is provided, a liquid crystal compound is filled in the gap, and the periphery thereof is sealed with a sealing material. In order to keep the cell gap between the color filter and the electrode substrate constant and uniform, particles (パール) with a certain particle size are dispersed in the gap part as spacers, or columnar or Strip spacers. [0003] In the color filter, a black matrix layer, a colored layer, a protective film and a transparent electrode film are sequentially stacked on the transparent substrate from the side close to the transparent substrate. The black matrix layer is formed in a predeter...
