(57) [Summary] [Purpose] It has properties such as heat resistance, low hygroscopicity, low dielectric constant and low residual stress, and has practical coating adhesion. Further, the present invention provides a novel polyimide precursor composition for screen printing, which is provided with thixotropy, is excellent in relief pattern forming property, and is excellent in product stability, and a simple production method thereof. A polyimide precursor composition having thixotropy obtained by heating a polyamic acid solution obtained by mixing or reacting an aromatic tetracarboxylic acid component, an aromatic diamine component and an oxygen-containing solvent. |
