Abstract

The invention relates to a thermosetting composition, a cured film which is obtained through the thermosetting composition, and a color filter. The thermosetting composition comprises the components of (A) a low-molecular-weight epoxide which comprises more than three epoxy groups and has a weight-average molecular weight that is smaller than 5000; (B) a high-molecular-weight epoxide which comprises more than three epoxy groups and has a weight-average molecular weight that is above 30000; and (C) a carboxyl compound which comprises more than three carboxyls. By means of the thermosetting composition, the cured film with two excellent characteristics of flatness and foreign body following property can be obtained.

Description

technical field [0001] The present invention relates to a thermosetting composition and a cured film obtained by heating the thermosetting composition. Background technique [0002] In the manufacturing process of elements such as liquid crystal display elements, various chemical treatments such as organic solvents, acids, and alkali solutions are performed, or when wiring electrodes are formed into a film by sputtering, the surface is locally heated to a high temperature . Therefore, a surface protective film may be provided for the purpose of preventing deterioration, damage, and deterioration of the surface of various elements. Properties capable of withstanding various treatments in the manufacturing steps as described above are required for these protective films. Specifically, chemical resistance such as solvent resistance, acid resistance, and alkali resistance, water resistance, heat resistance, adhesion to base substrates such as glass, transparency, scratch resis...
