Synthetic example 1

[0342] Synthesis example 1. Synthesis of photopolymerization initiator (C-1): (13-(2-ethylhexyl)-5-(2,4,6-trimethylbenzyl Acyl)-13H-dibenzo[a,i]carbazol-8-yl]-[4-(2,2,3,3-tetrafluoropropoxy)-phenyl]-ketone oxime-O- Acetate synthesis

[0343] As intermediate 13-(2-ethylhexyl)-13H-dibenzo[a,i]carbazole, 1-naphthylhydrazine hydrochloride was used instead of phenylhydrazine, and according to the following steps 1 to 4 disclosed The sequence of synthesis of photopolymerization initiator C-1.

[0344] Step 1: 13-(2-Ethylhexyl)-13H-dibenzo[a,i]carbazole

[0345] 13H-Dibenzo[a,i]carbazole can be produced according to a specific sequence, such as the sequence disclosed in the literature [SYNLETT, 2006, 7, 1021].

[0346] To 13H-dibenzo[a,i]carbazole (0.70 g, 3.22 mol) in DMF (3 ml) was added sodium hydride (0.19 g, 4.67 mmol) at 0°C. After stirring at 0°C for 1 hour, 1-naphthylhydrazine hydrochloride (1.24 g, 6.44 mmol) was added at 0°C, and the mixture was stirred at room te...

[0353] Synthesis example 2. Synthesis of photopolymerization initiator (C-2): 1-(9,9-H-7-nitrofluoren-2-yl)-acetoxime-O-acetate Synthesis

[0354] Step 1: Synthesis of 1-(9,9-H-7-nitrofluoren-2-yl)-ethanone

[0355]

[0356] Dissolve 5.0g (23.7mmol) of 2-nitrofluorene (1) in 100ml of anhydrous nitrobenzene, add 6.31g (47.4mmol) of anhydrous aluminum chloride, raise the temperature of the reactant to 45°C, and slowly A solution obtained by dissolving 2.79 g (35.5 mmol) of acetyl chloride in 30 ml of anhydrous nitrobenzene was added, and the reactant was heated up to 65° C. and stirred for 1 hour. Thereafter, the reactant was cooled to room temperature, 70 ml of distilled water was added and stirred for about 30 minutes, and then the product was filtered. The resulting solid product was dispersed in 50 ml of ether, stirred at room temperature for 30 minutes, filtered and dried to obtain pale yellow 1-(9,9-H-7-nitrofluoren-2-yl)-ethanone (2 ) 5.08 g (84.7%).

Abstract

The invention relates to a blue photosensitive resin composition, a color filter and a liquid crystal display device having the same, the blue photosensitive resin composition adopts an oxime ester derivative compound as a photopolymerization initiator which is used in a blue pigment, so that the close adaptation is good in a hot and humid environment, the stripping does not occur, and the liquid crystal bubble phenomenon can be improved. In addition, the color filter and liquid crystal display device are made by using the blue photosensitive resin composition, the pattern does not fall off, so that the reliability can be improved.

Description

technical field [0001] The present invention relates to a blue photosensitive resin composition, a color filter, and a liquid crystal display device containing the same. Background technique [0002] Color filters are widely used in image pickup devices, liquid crystal display devices, and the like, and their range of applications is rapidly expanding. A color filter used in a color liquid crystal display device or an imaging element is generally produced by uniformly applying a coloring agent containing colorants corresponding to red, green, and blue on a substrate having a pattern of a black matrix by spin coating. The photosensitive resin composition is then heat-dried (hereinafter, sometimes referred to as pre-fired), the formed coating film is exposed, developed, and further heat-cured (hereinafter sometimes referred to as post-fired) as needed and repeated in color. into) operations to form pixels of various colors. [0003] As such a colored photosensitive resin com...
