Abstract

The invention relates to a photosensitive composition, a hardened film, a color filter, an interlayer insulation film, and a coating type polarizer, wherein the photosensitive composition includes polyesteramide acid (A), an epoxy compound (B), a compound (C) which includes a compound having a carbamate framework and has polymerizable double bonds, a photo-polymerization initiator (D), and an additive (E); the polyesteramide acid (A) is prepared by a reaction to X mole of tetracarboxylic dianhydride, Y mole of diamine, and Z mole of a polyhydroxyl compound according to the ratio established inthe formula (1) or (2): 0.2 <= Z / Y <= 8.0 - (1); 0.2 <= (Y+Z) / X <= 5.0 - (2). On the basis of 100 weight parts of the polyesteramide acid (A), the total amount of the epoxy compound (B) is 20-200 weight parts and the same of the compound (C) having polymerizable double bonds is 20-300 weight parts.

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, an insulating film, and a coating-type polarizing plate using the cured film. Background technique [0002] In the manufacturing process of elements such as display elements, chemical treatment or high-temperature heat treatment is usually performed on the surface of the element. Therefore, in order to prevent deterioration, damage, and deterioration of the surface of the element, a protective film is often provided. Heat resistance, chemical resistance, adhesion to a substrate, transparency, flatness, and the like are required for a protective film incorporated in a display element. [0003] Protective films are roughly classified into thermosetting compositions and photocurable compositions according to their curing methods. A protective film made of a thermosetting composition is wide...
