Problems solved by technology

If conical protrusions with a large diameter are formed on the coating film, even if the protrusions are removed by grinding, they cannot be sufficiently flattened, which may cause display defects in liquid crystal display devices

Embodiment

[0170] The present invention will be described in more detail below by way of examples. "%" and "parts" in the examples are % by mass and parts by mass unless otherwise specified.

Synthetic example 1

[0172] Into a flask equipped with a reflux condenser, a dropping funnel, and a stirrer, nitrogen was flowed in at 0.02 L / min to form a nitrogen atmosphere, 140 parts of diethylene glycol ethyl methyl ether was charged, and heated to 70° C. while stirring. Next, prepare 40 parts of methacrylic acid; and the mixture of monomer (I-1) and monomer (II-1) {monomer (I-1) in the mixture: the mole of monomer (II-1) Ratio = 50:50} 360 parts of a solution dissolved in 190 parts of diethylene glycol ethyl methyl ether was dropped into a flask kept at 70°C over 4 hours using a dropping funnel.

[0173]

[0174] On the other hand, a solution obtained by dissolving 30 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) in 240 parts of diethylene glycol ethyl methyl ether was used with another drop The liquid pump dripped into the flask over 5 hours. After the dropwise addition of the polymerization initiator solution was completed, it was kept at 70° C. for 4 hou...

Synthetic example 2

[0176] In a flask equipped with a reflux condenser, a dropping funnel, and a stirrer, nitrogen was flowed in at 0.02 L / min to form a nitrogen atmosphere, and 200 parts by mass of 3-methoxy-1-butanol and 3-methoxyacetic acid were charged. 105 parts by mass of butyl butyl ester was heated to 70° C. while stirring. Next, prepare 60 parts of methacrylic acid; and a mixture of monomer (I-1) and monomer (II-1) {monomer (I-1) in the mixture: moles of monomer (II-1) Ratio = 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.

[0177] On the other hand, a solution obtained by dissolving 30 parts of the polymerization initiator 2,2'-azobis(2,4-dimethylvaleronitrile) in 225 parts of 3-methoxybutyl acetate was used in another The dropping funnel was dropped into the flask over 4 hours. After the dropwise addition of the polymerization initiator solution was completed, it was kept at 70° C. ...

Abstract

The present invention provides a curable resin composition comprising the following (A), (B) and (C), wherein the content of (B) is 20 parts by mass or more to 100 parts by mass relative to 100 parts by mass of the content of (A) the following. (A) Comprising a structural unit derived from at least one of unsaturated carboxylic acids and unsaturated carboxylic acid anhydrides, and a structural unit derived from a monomer having an oxiranyl group and a carbon-carbon unsaturated double bond Addition polymer (which does not have a carbon-carbon unsaturated double bond in the side chain.) (B) Resin (C) solvent having a carbon-carbon unsaturated double bond in the side chain and having a weight average molecular weight of 10,000 to 100,000.

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 have been used as components. The color filter protection film is used to flatten the surface unevenness generated in the color filter and black matrix as the base, or to protect the color filter, etc. from the chemical solution used for the components forming their upper layer coating film. In order to form a color filter protective film, curable resin composition is used. [0003] As such a curable resin composition, for example, a curable resin composition containing a copolymer of an unsaturated carboxylic acid and / or an anhydride of an unsaturated carboxylic acid and an aliphatic polycyclic epoxy compound, dipentaerythritol hexaacrylate, and a solvent is known. (Patent Document 1). [0004] [Patent Document 1] Japanese Patent Laid-Open No. 2009-149854 [...
