[0146] Next, the present invention will be specifically described by way of synthesis examples, examples, and comparative examples, but the present invention is not limited by these examples.

Synthetic example 1

[0147] [Synthesis Example 1] Synthesis of Alkali-Soluble Polymer Solution (A-1)

[0148] Into a four-necked flask equipped with a stirrer, diethylene glycol methyl ethyl ether (hereinafter abbreviated as "EDM"), methacrylic acid as the component (a1), and methacrylic acid as the component (a2) were charged with the following composition. Dicyclopentyl acrylate, N-cyclohexylmaleimide, and 2,2'-azobis(isobutyrate)dimethyl (hereinafter abbreviated as "V-601") as a polymerization initiator. V-601 is a trade name; Wako Pure Chemical Industries, Ltd.), and heating was performed at 115° C. for 3 hours.

[0149]

[0150] The solution after completion of the reaction was cooled to room temperature to obtain a 33.3% by weight solution of the alkali-soluble polymer (A-1). The weight average molecular weight determined by GPC analysis was 3,100.

[0151] Furthermore, the term "33.3% by weight solution of the alkali-soluble polymer (A-1)" here means the weight of the solid matter and ...

Abstract

The invention relates to a photosensitive composition, a cured membrane, a color filter, a display element, a solid shooting element, a touch screen and an LED illuminant body. The photosensitive composition contains an alkali soluble polymer (A), multifunctional epoxide (B), a compound with polymerized doubled bonds (C), a photopolymerization initiator (D), a 1, 2-quinondiazide compound (E) and a solvent (F). The photosensitive composition has favorable coating property and can form cured membranes with excellent sealed joint, transparency, heat resistance, flatness and in particular resolvability for substrates like glass.

Description

technical field [0001] The present invention relates to an insulating material in electronic parts, a passivation film, a buffer coating film, an interlayer insulating film, or a planarizing film in a semiconductor device, or an interlayer insulating film or a color filter in a display element A photosensitive composition used for forming a protective film, etc., a transparent film using the photosensitive composition, and an electronic component including the film. Background technique [0002] In the manufacturing process of elements such as display elements, various chemical treatments such as organic solvents, acids, and alkali solutions are performed, or the surface is locally heated to a high temperature when forming a film of wiring electrodes by sputtering. Therefore, a surface protective film may be provided in order to prevent deterioration, damage, and deterioration of the surface of various elements. These protective films are required to have various properties...
