The present invention relates to a thermosetting composition, a hard coating film and a color filter. The thermosetting composition comprises polyesteramide acid (A), an epoxy compound (B) and a compound (c) having polymerization double bonds, and is characterized in that the polyesteramide acid (A) is a reaction product of a raw material containing X mol of tetracarboxylic acid dianhydride, Y molof diamine and Z mol of polyhydroxy compound with a ratio enabling a formula (1) 0.2<=Z/Y<=8.0, and a formula (2) 0.2<=(Y+Z)/X<=5.0, and the compound (c) having the polymerization double bonds is a compound of which each molecule has more than two polymerization double bonds. According to the thermosetting composition of the present invention, the hard coating film preferably used for the electronic part and having excellent flatness and scratch resistance can be formed.

Description

Technical field [0001] The invention relates to an insulating material that can be used to form an insulating material in electronic parts, a passivation film in a semiconductor device, a buffer coating film, an interlayer insulating film, a planarization film, an interlayer insulating film in a liquid crystal display element, and a color filter A thermosetting composition such as a protective film for a color filter, a transparent film formed from the thermosetting composition, and an electronic component having the film. Background technique [0002] In the manufacturing steps of elements such as liquid crystal display elements, various chemical treatments such as organic solvents, acids, and alkaline solutions are sometimes performed, or when wiring electrodes are formed by sputtering, the surface is locally exposed to a high temperature. Next heating. Therefore, a surface protective film is sometimes provided for the purpose of preventing deterioration, damage, and deteriora...
