| titleOfInvention | Polyimide resin, method for producing polyimide resin, polyimide resin solution, coating material, and molding material |
| abstract | Provided is a polyimide resin excelling in solubility in a solvent, mechanical characteristics, and electrical characteristics. The polyimide resin is obtained by polymerizing a diamine component and an acid component. In the diamine component, a diamine compound A represented by formula (A) below accounts for 30.0-93.0 mol%, and 4,4'-oxydianiline accounts for 7.0-65.0 mol%, and in the acid component, pyromellitic dianhydride accounts for 1.0-70.0 mol%, and 3,3',4,4'-benzophenonetetracarboxylic acid dianhydride accounts for 23.0-92.0 mol%. In formula (A), R1, R2, R3 and R4 each represent hydrogen or an organic group having 1-4 carbons, and R1 and R2 may form a closed ring. |
