manufacture example 1

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

[0158]

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

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

[0161] Synthesis Example 1: Manufacture of a compound represented by Chemical Formula 3-1

[0162]

[0163] After adding potassium carbonate (0.04 mol) to the solution of INT (0.04 mol) and N-methylpyrrolidone (266.1 g) produced in Production Example 1 above, 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 liquid at 120° C. over 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, and stirring was performed over 4 hours. The reaction liquid 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), filtered through silica to remove impurities, and recrystallized with MeOH to obtain the compound represe...

[0166]

[0167]After adding potassium carbonate (0.04 mol) to the solution of INT (0.04 mol) and N-methylpyrrolidone (266.1 g) produced in Production Example 1 above, the temperature was raised to 120°C. A liquid obtained by dissolving 2,4-di(tert-butyl)phenol (0.04 mol) in N-methylpyrrolidone (88.7 g) was added to the above reaction liquid at 120° C. over 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, and stirring was performed over 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 methylene chloride (MC), filtered through silica to remove impurities, and recrystallized with MeOH to obtain t...

Abstract

The invention provides a self emission type photosensitive resin composition, a color filter comprising a color conversion layer using the same, and an image display device with the color filter. Theself emission type photosensitive resin composition comprises a fluorescent dye, binder resin, a photo-polymerizable compound, a photo-polymerization initiator and a solvent, and the fluorescent dye includes a perylenediimide compound. The self emission type photosensitive resin composition can improve the fluorescence efficiency of the color conversion layer through the included novel perylenediimide 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 specifically relates to a method capable of improving the fluorescence of the color conversion layer. 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 changed rapidly from CRT to flat panel displays represented by PDP, OLED, and LCD. 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, the LCD requires an additional backlight unit since there is no self-luminous ...
