Abstract

The invention provides a thermosetting compositions, a harden film, a color filter, a liquid crystal displaying element, a solid camera shooting element and a light emitting diode illuminant. The thermosetting composition contains polyester amide acid, epoxy group polymer, an epoxy compound and an epoxy hardening agent. The thermosetting composition is characterized in that the polyester amide acid is obtained by the reaction of the compounds comprising the tetracarboxylic dianhydride, the diamidogen and the multiple hydroxyl compounds; and the epoxy group polymer is obtained by the reaction of raw material components with methyl glycidyl acry late and two-function (methyl) acrylic ester. The thermosetting composition has excellent coating property; the harden film formed by the thermosetting composition has excellent light resistance and flatness, thermal resistance, resistance of solvent, acid and alkali, resistance of water, great sealing property for glass, transparency and scratch resistance.
