Problems solved by technology

However, Patent Document 2 discloses the transmittance or refractive index of a cured film formed from a photosensitive composition containing an acrylic resin, but the heat resistance cannot be sufficiently satisfied, and further improvement is required.
[0008] In addition, when inorganic fine particles are added to the photosensitive composition, if the dispersibility of the inorganic fine particles with respect to the resin contained in the photosensitive composition is poor, the aggregation of the inorganic fine particles may occur, which may lead to the formation of the cured film obtained. Reduced transmittance or reduced residual film rate and other issues

Abstract

The present invention relates to photosensitive compositions, a hardening film, a color filter and an electronic device. The photosensitive compositions comprise polyesteramide, compounds, a photopolymerization initiator, epoxy compound, epoxy hardener and inorganic corpuscule, wherein the polyesteramide is obtained through reaction by taking tetracarboxylic anhydride, diamidogen and multiple hydroxyl compounds as necessary raw materials. The photosensitive compositions can form heat-resistant, transparent and flat hardening film with good a plastic film residue rate, analyticity and a refractive index.

Description

technical field [0001] The present invention relates to a photosensitive composition used for various elements, a cured film formed from the photosensitive composition, and a color filter and an electronic device using the cured 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. For these protective films, various properties that can withstand various treatments in the above-mentioned manufacturing steps are required. Specifically, chemical resistance such as heat resistance, solvent resistance, acid resistance, and alkali resistance, water resistance, adhesion to base su...
