Problems solved by technology

When conical protrusions with a large diameter are formed on the coating film, even if the protrusions are removed by grinding, the surface cannot be sufficiently flattened, and display defects may occur in liquid crystal display devices.
When using the curable resin composition proposed so far, when forming a coating film on a color filter with foreign matter of several μm or so, the diameter of the conical protrusions generated around the foreign matter may not be sufficiently satisfactory.

Synthetic example 1

[0240] In a flask equipped with a reflux condenser, a dropping funnel, and a stirrer, nitrogen gas was passed through at 0.02 L / min to form a nitrogen atmosphere, 140 parts of diethylene glycol ethyl methyl ether was added, and the mixture was heated to 70° C. while stirring. Next, prepare 40 parts of methacrylic acid, and the mixture of monomer (I-1) and monomer (II-1) {the molar ratio of monomer (I-1) in the mixture:monomer (II-1) =50:50} The solution obtained by dissolving 360 parts in 190 parts of diethylene glycol ethyl methyl ether was dropped into the flask whose temperature was kept at 70°C over 4 hours using a dropping funnel.

[0242] On the other hand, using another drip pump, 30 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) was dissolved in diethylene glycol ethyl methyl ether 240 The resulting solution was added dropwise to the flask over 5 hours. After the dropwise addition of the polymerization initiator solution was c...

[0245] In a flask equipped with a reflux condenser, a dropping funnel, and a stirrer, pass nitrogen gas at 0.02 L / min to form a nitrogen atmosphere, and add 200 parts by mass of 3-methoxy-1-butanol and 3-methoxybutyl 105 parts by mass of acetate was heated to 70° C. while stirring. Next, prepare 60 parts of methacrylic acid, and the mixture of monomer (I-1) and monomer (II-1) {the molar ratio of monomer (I-1) in the mixture:monomer (II-1) =50:50} 240 parts of a solution dissolved in 140 parts of 3-methoxybutyl acetate was dropped into a flask kept at 70°C over 4 hours using a drip pump.

[0246] On the other hand, using another dropping funnel, dissolve 30 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) in 225 parts of 3-methoxybutyl acetate The resulting solution was added dropwise to the flask over 4 hours. After the dropwise addition of the polymerization initiator solution was completed, it was kept at 70° C. for 4 hours, and then cooled to r...

Abstract

The present invention provides a curable resin composition comprising the following (A), (B) and (C), wherein the content of (B) is 1 part by mass or more and 10 parts by mass relative to 100 parts by mass of the content of (A). Even if a coating film is formed on a color filter having foreign matter of several μm or so on the surface, the diameter of the conical protrusions formed around the foreign matter becomes smaller. Therefore, display defects of a liquid crystal display device can be reduced by polishing the formed coating film and using it for a liquid crystal display device. (A): A copolymer comprising a structural unit derived from at least one selected from unsaturated carboxylic acid and unsaturated carboxylic acid anhydride, and a structural unit derived from a monomer having an oxiranyl group and an ethylenically unsaturated bond, (B): at least one compound selected from a silane compound containing an amino group which may have a substituent, and a silane compound which may have an imidazolyl group which may have a substituent (C): a solvent.

Description

technical field [0001] The present invention relates to curable resin compositions. Background technique [0002] In liquid crystal display devices and the like, coating films such as color filter protection films are used as components. The color filter protective film is used to flatten the unevenness (not level) of the surface of the color filter or black matrix as the bottom layer, or to protect the color filter and the like from the chemical solution used to form their upper layer. Damaged coating film. In order to form a color filter protective film, curable resin composition can be used. [0003] As these curable resin compositions, for example, in JP 2009-149854 A, copolymers of unsaturated carboxylic acids and / or unsaturated carboxylic acid anhydrides and aliphatic polycyclic epoxides, dipentaerythritol hexaacrylate are known. (dipentaerythritol hexaacrylate) and a solvent mixed curable resin composition. [0004] When a coating film is formed on a color filter ...
