[0188]

[0189] In a flask with a stirrer, a thermometer, a reflux condenser, a dropping funnel, and a nitrogen introduction tube, mix and introduce 90g propylene glycol monomethyl ether acetate, 90g propylene glycol monomethyl ether, and 11.0g 2-norbornene (2- norbornene) (0.10mol), after replacing the air in the flask with nitrogen, the temperature was raised to 80°C, and the following solution was added dropwise from the dropping funnel to the flask for 2 hours. The solution contained 70.5g benzyl Add 3.2g tert-butyl peroxy 2-ethylhexyl carbonate in the mixture of methacrylate (0.4mol), 45.0g methacrylic acid (0.5mol) and 136g propylene glycol monomethyl ether acetate, at 100 Stirring was continued for 5 hours at °C. Then, the nitrogen in the flask was replaced with air, and 30 g of glycidyl methacrylate [0.2 mol (40 mol % of the carboxyl group of methacrylic acid used in the present invention)], 0.9 g of tris(dimethylaminomethyl) base) phenol and 0.145 g of hydroquinone...

Abstract

The present invention relates to a dyeing photosensitive resin combination, a colorful color filter and a liquid crystal display apparatus with the colorful color filter, wherein the dyeing photosensitive resin combination contains a dyeing material (A), a bonder resin (B), a photopolymerization compound (C), a photopolymerization initiator (D) and a dissolvent (E), and the photopolymerization initiator (D) contains a compound with at least two photoactivity oxime ester rameworks contained by one molecule. The dyeing photosensitive resin combination can not appear pattern deficiency and transparence decrease under low exposure degree, thereby being capable of providing an excellent colorful color filter and a liquid crystal display apparatus with the colorful color filter.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a color filter and a liquid crystal display device having the color filter. The colored photosensitive resin composition is used in a thin film transistor (TFT) color liquid crystal display device A colored layer containing pixels of a color liquid crystal display device is formed on the driving substrate. Background technique [0002] Color filters are widely used in imaging elements, liquid crystal display devices (LCDs), and the like, and their range of applications is rapidly expanding. Color filters used in color liquid crystal display devices, imaging elements, and the like are generally produced as follows. On the substrate formed with the black matrix pattern, the colored photosensitive resin composition is uniformly coated by spin coating, and the colored photosensitive resin composition contains pigments of various colors corresponding to red, green and blue, and th...
