Problems solved by technology

[0004] However, in pursuit of process simplification and high light transmittance of color filters, the industry usually omits the protective film on the pixel coloring layer. However, due to the omission of the protective film, it occurs during the subsequent sputtering forming process of the transparent conductive film. The use of the pixel coloring layer disclosed in JP-A-1995-234313 cannot directly withstand the powerful electron beam of the sputtering process, resulting in the problem of cracking

specific Embodiment approach

[0095] According to the specific embodiment of the present invention, preferably, the photoinitiator C is 2-methyl-1-(4-methylthiophenyl)-2-morpholino-1-propanone, 2-benzyl -2-nitrogen, nitrogen-dimethylamine-1-(4-morpholinophenyl)-1-butanone, 2,2'-bis(o-chlorophenyl)-4,4',5,5 '-Tetraphenyl diimidazole, ethane ketone, 1-[9-ethyl-6-(2-methylbenzoyl)-9hydro-carbazole-3-substituent)-,1-(oxy- Acetyl oxime), or a combination thereof.

[0096] In the photoinitiator C of the present invention, the following compounds can be further added: thioxanthone, 2,4-diethyl-thioxanthanone, thioxanthone-4- Sulfone (thioxanthone-4-sulfone), benzophenone, 4,4'-bis(dimethylamino)benzophenone [4,4'-bis(dimethylamino)benzophenone], 4,4'- Bis (diethylamine) benzophenone [4,4'-bis(diethylamino)benzophenone] and other benzophenone compounds; benzil, acetyl and other α-diketones (α-diketone); acyloins such as benzoin; benzoin methylether, benzoin ethylether, benzoin ethylether Acyloin ether such as ben...

Synthetic example A-1

[0182] A four-necked conical flask with a volume of 1000 ml is equipped with a nitrogen inlet, agitator, heater, condenser, and thermometer, and nitrogen is introduced. According to the component types and use ratios shown in Table 1, the preparation is used to synthesize the alkali-soluble resin Required first unsaturated monomer, second unsaturated monomer, polymerization initiator, solvent and other components.

[0183] During polymerization, 5 parts by weight of 2-methacryloyloxyethyl succinate monoester (hereinafter referred to as HOMS) and 5 parts by weight of dicyclopentenyl acrylate (hereinafter referred to as HOMS) (FA-511A for short), 40 parts by weight of styrene monomer (SM) and 50 parts by weight of methyl methacrylate (MMA) are put into a four-necked conical flask, and are stirred and mixed. At the same time, the temperature of the oil bath of the four-necked Erlenmeyer flask was increased to 100°C; and 6 parts by weight of 2,2'-azobis-2-methyl butyronitrile (2,2'-a...

Synthetic example F-1

[0187] Synthesis Example F-1: Synthesis of N,N-diallyl-3-(propylamino)propionamide

[0188] Under constant stirring, dichloromethane (1:1 v / v) containing 3-bromopropionyl chloride was added dropwise to dichloromethane (DCM) containing a slight molar excess of diallylamine at about 10°C over 2 hours in. Then wash with diluted HCl and dichloromethane and keep the organic part. Then the product in the dichloromethane solution was purified by column chromatography using silica (60A), and then the dichloromethane was removed to obtain the 3-bromo-N,N-diallylpropionamide intermediate; Yellow liquid. The yield is 70%.

[0189] The 3-bromo-N,N-diallylpropionamide intermediate (30 g, 129 mmol) was added to THF (1:1 v / v). Then it was added dropwise over 2 hours to a stirred refluxing mixture of 1-propylamine (43.1 g, 0.730 mmol), potassium carbonate (90 g, 0.652 mmol) and THF (133.6 g, 1.850 mmol). The reflux was then cooled for 1 hour under constant stirring.

Abstract

The invention relates to a photosensitive resin composition that has the advantages of high developability, good hardness, and good sputtered resistance. The invention also provides a method for manufacturing a color filter, color filter and a liquid crystal display device. The photosensitive resin composition comprises an alkali-soluble resin (A), a compound containing an ethylenically unsaturated group (B), a photoinitiator (C), an organic solvent (D), a pigment (E), and a compound (F).

Description

Technical field [0001] The invention relates to a photosensitive resin composition for a color filter in a liquid crystal display, a color filter formed therefrom, and a liquid crystal display device; in particular, it provides a color with excellent developability, hardness and sputter resistance The photosensitive resin composition for the filter, the color filter and the liquid crystal display device formed by it. Background technique [0002] As color filters are widely used in color liquid crystal displays, color fax machines, color cameras and other fields, the production technology of color filters is also diversified, such as dyeing method, printing method, electroplating method, pigment dispersion method, etc. The pigment dispersion method is now the mainstream. The method of making color filters by pigment dispersion method is usually to form a black matrix for shading with metal chromium / chromium oxide or photosensitive resin on a glass substrate, and then disperse th...
