Embodiment approach

[0197] Hereinafter, the present invention will be explained in more detail with reference to examples and comparative examples. However, the following examples and comparative examples are provided for descriptive purposes and the present invention is not limited thereto.

[0198] (Compound synthesis)

Synthetic example 1

[0199] Synthesis Example 1: Synthesis of 4-(biphenyl-2-yloxy)-3,5,6-trichloro-phthalonitrile

[0200] Combine 3,4,5,6-tetrachlorophthalonitrile (3,4,5,6-tetrachlorophthalonitrile) (5g), 2-phenylphenol (3.201g), K 2 CO 3 (3.898g) and acetonitrile (50ml) were placed in a 100ml flask and then heated and refluxed. When the reaction was completed, the resultant was filtered and washed with tetrahydrofuran, and then concentrated to obtain a solid. In this article, the obtained solid was washed several times with hexane, filtered and dried in vacuum to obtain 4-(biphenyl-2-yloxy)-3,5,6-trichloro-phthalonitrile.

Synthetic example 2

[0201] Synthesis Example 2: Synthesis of 3,4,6-trichloro-5-(2,6-dimethoxy-phenoxy)-phthalonitrile

[0202] Combine 3,4,5,6-tetrachlorophthalonitrile (5g), 2,6-dimethoxyphenol (7.21g), K 2 CO 3 (3.898g) and N,N-dimethylformamide (50ml) were placed in a 100ml flask and then heated and stirred at 70°C. When the reaction was completed, the resultant was extracted with ethyl acetate (EA). After extraction, the resultant was concentrated and purified via column chromatography, followed by concentration and vacuum drying to obtain 3,4,6-trichloro-5-(2,6-dimethoxy-phenoxy)-o-benzene Dicarbonitrile.

Abstract

Provided are a compound represented by a specific chemical formula, a photosensitive resin composition containing the same, and a color filter manufactured using the photosensitive resin composition.

Description

Technical field [0001] The present invention relates to a compound, a photosensitive resin composition containing the compound, and a color filter. Background technique [0002] The color filter manufactured by using a pigment-type photosensitive resin composition has limitations in brightness and contrast ratio due to the particle size of the pigment. In addition, the imaging sensor device requires a smaller dispersion particle size to form a fine pattern. To meet the demand, attempts have been made to produce a photosensitive resin composition by introducing dyes that do not form particles instead of pigments to realize color filters with improved color characteristics (such as brightness, contrast ratio, etc.). [0003] Therefore, it is necessary to study an appropriate compound as a dye for the production of a photosensitive resin composition. Summary of the invention [0004] [Technical direction] [0005] One embodiment provides a novel compound. [0006] Another embodiment pr...
