Abstract
The present invention relates to a novel di-amine compound, a heat-resistant resin using the di-amine compound, and a resin composition using the heat-resistant resin, and a cured film excellent in chemical resistance and film properties even by a thermal treatment at a low temperature of 200° C. or less can be obtained. The novel di-amine compound is represented by the general formula (1). The heat-resistant resin composition of the present invention or the resin composition can be suitably used in a surface protective film and an interlayer dielectric film of a semiconductor device, a dielectric layer or a planarizing layer of an organic electroluminescent element (organic EL), or the like. (In the general formula (1), Rand Reach are a divalent aliphatic group, Rand Reach are a divalent aliphatic group, aliphatic ring group, aromatic group, a divalent organic group bonded to an aromatic group by —O—, —CO—, —SO—, —CH—, —C(CH)— or —C(CF)— (wherein F is fluorine), a divalent organic group in which two or more aromatic groups are bonded by a single bond, or a divalent organic group in which two or more aromatic groups are bonded by —O—, —CO—, —SO—, —CH—, —C(CH)— or —C(CF)— (wherein F is fluorine), Rand Reach are an organic group having any of a hydrogen atom, a halogen atom, a hydroxyl group, a nitro group, a cyano group, an aliphatic group, an aromatic group, an acetyl group, a carboxyl group, an ester group, an amide group, an imide group, and a urea group, A is a divalent aliphatic group, aliphatic ring group, aromatic group, a divalent organic group in which two or more aromatic groups are bonded by a single bond, or a divalent organic group in which two or more aromatic groups are bonded by —O—, —S—, —CO—, —SO—, —CH—, —C(CH)— or —C(CF)— (wherein F is fluorine), p and q each are an integer number in the range of 0 to 3).
