[0157] Production Example 1: Synthesis of Intermediate Compound (INT)

[0158]

[0159] 1,6,7,12-Tetrachloroperylenetetracarboxylic dianhydride (0.11 mol) and 2,6-diisopropylaniline (0.44 mol) were put into 1 L of propionic acid, heated up, and the reaction was maintained at 140°C 5 hours. The reaction solution was cooled to room temperature, and the precipitate was filtered under reduced pressure and washed with methanol and water. The filtrate was dispersed in water, maintained for 30 minutes, filtered under reduced pressure, dispersed in methanol again, maintained for 30 minutes, and then filtered under reduced pressure. After drying, the intermediate compound (INT) was obtained in a yield of 80.5%.

[0160] About the obtained intermediate compound, MS (mass spectrometry) was measured using a MALDI-TOF measuring apparatus. As a result, it was confirmed that the molecular weight was 848.16.

[0161] Synthesis Example 1: Production of Compound Represented by Chemical Formula 3-1

[0162]

[0163] Potassium carbonate (0.04 mol) was added to the solution of INT (0.04 mol) and N-methylpyrrolidone (266.1 g) produced in Production Example 1, and the temperature was raised to 120°C. A liquid obtained by dissolving 4-fluorophenol (0.04 mol) in N-methylpyrrolidone (88.7 g) was added to the reaction solution at 120° C. for 2 hours. After maintaining the reaction at the same temperature for 1 hour, 4-chlorophenol (0.16 mol) and potassium carbonate (0.16 mol) were added, followed by stirring for 4 hours. The reaction solution was cooled to room temperature and discharged into 3 L of distilled water. The resulting red-purple precipitate was filtered under reduced pressure and washed with methanol water. The filtrate was redissolved in dichloromethane (MC), silica filtration was performed to remove impurities, and recrystallization was performed with MeOH to obtain the comp...

[0167]Potassium carbonate (0.04 mol) was added to the solution of INT (0.04 mol) and N-methylpyrrolidone (266.1 g) produced in Production Example 1, and the temperature was raised to 120°C. A liquid obtained by dissolving 2,4-bis(tert-butyl)phenol (0.04 mol) in N-methylpyrrolidone (88.7 g) was added to the reaction solution at 120° C. for 2 hours. After maintaining the reaction at the same temperature for 1 hour, 4-chlorophenol (0.16 mol) and potassium carbonate (0.16 mol) were added, followed by stirring for 4 hours.

Abstract

The present invention provides a self-luminous photosensitive resin composition, a color filter including a color conversion layer using the self-luminous photosensitive resin composition, and an image display device having the above-mentioned color filter, and a self-luminous photosensitive resin composition. The compound includes a fluorescent dye, a binder resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent, and the fluorescent dye includes a perylene bisimide compound. The self-luminous photosensitive resin composition according to the present invention can improve the fluorescence efficiency of the color conversion layer by including the novel perylenebisimide-based fluorescent dye.

Description

technical field [0001] The present invention relates to a self-luminous photosensitive resin composition, a color filter and an image display device including a color conversion layer using the self-luminous photosensitive resin composition, and more particularly, to a color conversion layer capable of improving fluorescence An efficient self-luminous photosensitive resin composition, a color filter including a color conversion layer using the self-luminous photosensitive resin composition, and an image display device having the color filter. Background technique [0002] In recent years, the display industry has been rapidly changing from CRTs to flat panel displays represented by PDPs, OLEDs, and LCDs. Among these, a liquid crystal display device (LCD) has been widely used as an image display device in all industries, and its application range is continuously expanding. However, since LCDs do not have self-luminous elements, they require an additional backlight unit. [...
