[0117] Preparation Example 1: Synthesis of Compounds of Chemical Formula 1-1-1

[0118] Mix 3', 6'-dihydroxyspiro (fluorene-9,9'-xanthene) (3', 6''-dihydroxyspiro (fluorene-9, 9-xantene) 364.4g and 0.4159g of tert-butyl ammonium bromide, and after adding 2359g of epichlorohydrin, heat to 90°C and make it react. Analyze by liquid chromatography, if 3',6'-dihydroxyspiro (fluorene-9,9'- Xanthene) is completely consumed, then cooled to 30 ° C, slowly added 50% NaOH aqueous solution (3 equivalents). Analyze by liquid chromatography, if epichlorohydrin is completely consumed, then use dichloromethane to extract and wash 3 times, Then, dichloromethane was distilled under reduced pressure after drying the organic layer with magnesium sulfate, and recrystallization was performed using dichloromethane and methanol at a mixing ratio of 50:50.

[0122] Preparation Example 2: Synthesis of Cardo-based Binder Resin (C-1)

[0123] After adding 600 g of propylene glycol monomethyl ether acetate to 307.0 g of the compound of chemical formula 1-1-1 of Preparation Example 1 and dissolving it, 78 g of biphenyltetracarboxylic dianhydride and 1 g of tetraethylammonium bromide were mixed. , make it warm up slowly and react at 110-115° C. for 4 hours. After confirming that the acid anhydride group disappeared, 38.0 g of 1,2,3,6-tetrahydrophthalic anhydride was mixed, reacted at 90° C. for 6 hours, and polymerized into a Cardo-based binder resin. The disappearance of the anhydrate was confirmed by IR spectrum. The weight average molecular weight was 3500.

Description

technical field [0001] The present invention relates to a blue photosensitive resin composition, a color filter and an image display device manufactured using the composition. Background technique [0002] A color filter is a thin-film optical component that can realize tiny pixel units by extracting three colors of red, green, and blue from white light, and the size of one pixel is about tens to hundreds of microns. Such a color filter has a structure in which a black matrix layer and a pixel portion are sequentially stacked. The black matrix layer is formed in a predetermined pattern on a transparent substrate to shield light at the border between pixels. The pixel portion is for Each pixel is formed by arranging three primary colors of a plurality of colors (usually red (R), green (G) and blue (B)) in a predetermined order. [0003] In recent years, a pigment dispersion method using a pigment-dispersed photosensitive resin has been used as one of the methods for realizin...
