Problems solved by technology

However, there is a problem that the solubility of bisphenol fluorene epoxy compounds is low, and the compatibility with other epoxy compounds and the solubility to solvents are limited, so it becomes a big obstacle in the design of thermosetting compositions.

Embodiment 1

[0046] (production of thermosetting composition)

[0047] The mixture was blended according to the composition shown in Table 1, and stirred and mixed at room temperature for 3 hours to dissolve the solid content in the solvent to prepare a thermosetting composition. The numerical value of a composition is mass parts, and it describes so that the total of solid content may become 100 mass parts. Among the solid components, there are also components that are synthesized in the state of being dissolved in a solvent (propylene glycol monomethyl ether acetate) from the beginning, but in this case, the numerical value of the composition indicates the solvent carried in as a mass part of the solid content Components are described as parts by mass contained in the solvent. Components used in the compounding of the examples are as follows.

[0048] A-1: An epoxy compound represented by general formula (1) and having an average value of n of 0.2

[0049] A-2: Epoxy compound represen...

Embodiment 2～15

[0101] The composition of Example 1 was changed as shown in Table 1, and the preparation and evaluation of thermosetting compositions of Examples 2 to 15 were carried out in the same manner as in Example 1. The evaluation results are shown in Table 2. The curable compositions of Examples 2 to 15 simultaneously satisfied the flatness, heat resistance, adhesion, and hardness required for a protective film of a color filter, and were also excellent in chemical resistance, electrical reliability, and transparency.

Abstract

The invention relates to a kind of thermosetting composition, a curing film and a filter. The invention provides a kind of thermosetting composition and the curing film thereof that can be used as filter protection film with flatness, heat resistance, chemical resistance, adhesiveness, hardness, electrical reliability and transparency. A kind of thermosetting composition is characterized in containing epoxy compound (A), epoxy compound (B) and a curing agent (C), wherein the epoxy compound (A) is expressed by formula (1), and the avenue value of n is 0.2-1.0; the epoxy compound (B) is obtained through polymerizing or copolymerizing more than 1 polymerizable unsaturated compound that takes glycidyl methacrylate as an essential ingredient. When epoxy equivalent is smaller than 200g / eq and number-average molecular weight less than 10 thousand, the curing agent (C) is selected from polycarboxylic acid, anhydride of polycarboxylic acid and thermal decomposition ester of polycarboxylic acid. The above thermosetting composition is cured to obtain the curing film.

Description

technical field [0001] The present invention relates to a novel thermosetting composition, a cured film obtained by curing the composition, and a color filter protected by the cured film. Background technique [0002] Conventionally, it has been performed to form a transparent cured film (hereinafter also referred to as a protective film) as a protective layer on the surface of a color filter used in the production of a color liquid crystal display. The functions of the protective film of the color filter include flattening the unevenness generated between the pixels of the color filter, improving the durability of the color filter for heat treatment and chemical treatment in the subsequent process, and making the liquid crystal display To improve reliability, etc., materials excellent in flatness, heat resistance, chemical resistance, adhesiveness, hardness, electrical reliability, and transparency are required. [0003] For example, as flatness, it is required to flatten ...
