preparation example Construction

[0214]

[0215] The radiation-sensitive resin composition is prepared, for example, by mixing [A] the polymer component and [B] the radiation-sensitive acid generator, optional preferred components, and other optional components in a [H] solvent to dissolve or scattered state.

[0216]

[0217] The cured film of this invention is formed from the said radiation sensitive resin composition. Since the said cured film is formed from the said radiation sensitive resin composition, it is excellent in radiation sensitivity, chemical resistance, transparency, the pattern adhesiveness after image development, and the pattern adhesiveness after exposure-standing. The cured film having such characteristics can be used, for example, as an interlayer insulating film, a planarizing film, a bank (partition wall), a spacer, a protective film, etc. Coloring patterns for color filters, etc. In addition, the formation method of the said cured film is not specifically limited, It is prefera...

[0278] Into a flask equipped with a cooling tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of methyl-3-methoxypropionate were charged. 30 parts by mass of the compound (M-1), 40 parts by mass of the compound (M-3), and 30 parts by mass of the compound (M-7) were charged into the flask and replaced with nitrogen, and then stirring was gradually started. The temperature of the solution was raised to 70° C., and the temperature was maintained for 6 hours, whereby a polymer solution containing the polymer (A-1) was obtained. The solid content concentration of the polymer solution was 32.5% by mass. Polystyrene conversion weight average molecular weight (Mw) of polymer (A-1) was 10,000.

Abstract

The present invention provides a sensitivity radioactive ray resin composite, a hard coating film formed by the composite, a formation method thereof, and a display element. The sensitivity radioactive ray resin composite is excellent in the radioactive ray sensitivity and storage stability, and can form chemical resistance and pattern adaptation after development and exposure, and is excellent in transparency. The resin composite contains: [A] polymer composition containing the group and the structural unit with a crosslinked base shown in the formula (1), and [B] the sensitivity radioactive ray linear acid generation body containing at least one of the oxime sulfonic acid ester based compound and the N - imide sulfonyl oxygen radical compound shown in the formula (2).

Description

technical field [0001] The present invention relates to a radiation-sensitive resin composition, a cured film, a method for forming the same, and a display element. Background technique [0002] A display element such as a thin film transistor liquid crystal display element or an organic electroluminescence device (organic electroluminescence device, organic EL element) generally includes an insulating film such as an interlayer insulating film or a planarizing film. The insulating film is usually formed using a radiation-sensitive composition. As the radiation-sensitive composition, a positive-type radiation-sensitive resin composition using an acid generator such as naphthoquinonediazide (refer to Japanese Patent Laid-Open No. 2001- 354822 bulletin), in recent years proposed a variety of radiation-sensitive composition. [0003] As an example, a positive-type chemical amplification material has been proposed for the purpose of forming a display element with a higher sens...
