Problems solved by technology

In order to avoid the generation of such residues and scum, it is effective to increase the development time, but if the development time is increased, there is a disadvantage that the production interval becomes longer
[0004] In addition, when the concentration of the coloring agent contained in the colored radiation-sensitive composition becomes higher, the solubility of the coating film in an alkaline developing solution tends to decrease significantly.
Therefore, when developing by the shower developing method, once peeled off, the unexposed portion of the coating film is not completely dissolved in the developing tank and floats, becoming foreign matter and adhering to the color filter, which is the most important factor in the reduction of product yield.

[0246] Hereinafter, an embodiment of the present invention will be described in more detail by way of examples. However, the present invention is not limited to the following examples.

[0247]

[0248] Mw and Mn of the polymers obtained in the following synthesis examples were measured by gel permeation chromatography (hereinafter, abbreviated as GPC) in the following format.

[0249] Device: GPC-104 (manufactured by Showa Denko Co., Ltd.).

[0250] Column: Use KD-G, KF-603, KF-602, and KF-601 in combination.

[0251] Mobile phase: tetrahydrofuran.

[0252]

[0253] The acid value of the polymer obtained in each synthesis example below was measured by the following method.

[0254] Weigh 0.5 g of the polymer solution to an accuracy of 1 mg, and dispense into glass containers. After diluting to 50 mL with propylene glycol monomethyl ether acetate, phenolphthalein was added and titrated with a 0.1N ethanolic potassium hydroxide aqueous solution, and the point where it w...

Synthetic example 1

[0259] 194.4 parts by mass of cyclohexanone were placed in a flask equipped with a cooling tube and a stirrer, and nitrogen substitution was performed. Heated to 80°C, and at this temperature, 60 parts by mass of propylene glycol monomethyl ether acetate, 60 parts by mass of methacrylic acid, 30 parts by mass of butyl methacrylate, EO modified 2-ethyl acrylic acid A mixed solution of 30 parts by mass of methylhexyl ester (manufactured by Toagosei Co., Ltd., M-120) and 18 parts by mass of cyclohexyl methacrylate, and 45.6 parts by mass of propylene glycol monomethyl ether and 2,2'-azobis(2, 4-Dimethylvaleronitrile) 10.8 parts by mass of the mixed solution, and kept the temperature for polymerization for 1 hour.

Abstract

The invention provides a curable composition, a cured film, a display device and a dry film. The curable composition has an excellent developing property when the concentration of a coloring agent is high, and thus a color filter can be formed at a high rate of finished products. The curable composition is characterized by comprising a polymer (A) and a solvent (B), wherein the polymer (A) comprises groups of substituted or non-substituted alicyclic hydrocarbon groups and polymerized unsaturated groups shown as the following formula (1) which is defined in the specification, (in the formula (1), R1 represents alkanediyl group with a carbon number of from 2 to 4, R2 represent an aliphatic hydrocarbon group, n represents an integer from 1 to 100, and * represents a binding site, wherein when n is 2 or greater, the plurality of R1s may be different or not.)

Description

technical field [0001] The present invention relates to a curable composition, a cured film, and a display element. More specifically, it relates to a cured film used in a transmissive or reflective color liquid crystal display element, a solid-state imaging element, an organic EL display element, and electronic paper. A curable composition used for formation, a cured film formed using the curable composition, and a display element including the cured film. Background technique [0002] When producing a color filter using a colored radiation-sensitive composition, it is known that after coating a pigment-dispersed colored radiation-sensitive composition on a substrate and drying it, the dry coating film is irradiated with radiation (called "exposure") to make it A method of developing into a desired pattern shape to obtain pixels of each color (for example, Patent Documents 1 and 2). Moreover, the method of forming a black matrix using the photopolymerizable composition in ...
