Synthetic example 1

[0172] Synthesis Example 1: Synthesis of 3,5,6-trichloro-4-(2,4-di-tert-butylphenoxy)-phthalonitrile

[0173] 3,4,5,6-tetrachlorophthalonitrile (5g), 2,4-di-tert-butylphenol (3.8g), K 2 CO 3 (3.898 g) and N,N-dimethylformamide (50 ml) were placed in a 100 ml flask and then stirred while heating at 70°C. When the reaction was complete, the resultant was extracted with ethyl acetate (EA). After extraction, the product was purified by column chromatography with EA / hexane to obtain a liquid, the liquid was concentrated to obtain a solid, and the solid was dried in vacuo, thereby obtaining the compound represented by Synthesis Example 1.

Synthetic example 2

[0174] Synthesis Example 2: Synthesis of 3,5,6-trichloro-4-(2,6-dimethylphenoxy)-phthalonitrile

[0175] 3,4,5,6-tetrachlorophthalonitrile (5g), 2,6-dimethylphenol (6.6g), K 2 CO 3 (3.898g) and acetone (50ml) were placed in a 100ml flask and then stirred while heating at 50°C. When the reaction was complete, the resultant was extracted with EA (ethyl acetate). After extraction, the product was purified by column chromatography with EA / hexane to obtain a liquid, the liquid was concentrated to obtain a solid, and the solid was dried in vacuo, thereby obtaining the compound represented by Synthesis Example 2.

Synthetic example 3

[0176] Synthesis Example 3: Synthesis of 3,5,6-trichloro-4-(2-tert-butylphenoxy)-phthalonitrile

[0177] 3,4,5,6-tetrachlorophthalonitrile (5g), 2-tert-butylphenol (6.64g), K 2 CO 3 (3.898g) and acetone (50ml) were placed in a 100ml flask and then stirred while heating at 50°C. When the reaction was complete, the resultant was extracted with EA (ethyl acetate). After extraction, the product was purified by column chromatography with EA / hexane to obtain a liquid, the liquid was concentrated to obtain a solid, and the solid was dried in vacuo, thereby obtaining the compound represented by Synthesis Example 3.

Abstract

The present invention provides a compound represented by Chemical Formula 1, a photosensitive resin composition including the same, and a color filter manufactured using the photosensitive resin composition. In Chemical Formula 1, each substituent is the same as defined in the detailed description. The compound provided by the present invention has excellent green spectral characteristics, high molar extinction coefficient, and improved solubility in organic solvents, and thus can be used as a dye during the preparation of a photosensitive resin composition for a green filter, and contains all Color filters with the above dyes can have excellent brightness and contrast ratio. [chemical formula 1]

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0089065 filed with the Korean Intellectual Property Office on June 23, 2015, the entire disclosure of which is incorporated herein by reference middle. technical field [0003] The present invention relates to a compound, a photosensitive resin composition and a color filter containing the compound. Background technique [0004] A 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, imaging sensor devices require smaller dispersed particle sizes to form fine patterns. In order to meet the requirements, attempts have been made to manufacture photosensitive resin compositions by introducing non-particle-forming dyes instead of pigments to realize color filters with improved color characteristics such a...
