Patent ID: 7592119

Claim:
A photosensitive polyimide resin composition capable of being developed in a positive manner with a weakly alkaline aqueous solution and soluble in an organic solvent, the photosensitive polyimide resin composition comprising: a polyimide resin including a polyimide unit represented by the following formula (1) and a polyimide unit represented by one of the following formulas (2) and (3); an analogue of melamine cyanurate; and an analogue of diazonaphthoquinone; wherein an amount of the analogue of melamine cyanurate is in a range of from 5 to 50 parts by weight with respect to 100 parts by weight of the polyimide resin; where, in the formulas (1) to (3), X and A are each independently a single bond or a divalent organic group, R1 is an alkylene group having 3 to 9 carbon atoms, R2, R3, R4, and R5 are each independently an alkylene group having 1 to 8 carbon atoms or an aromatic group, R is an alkylene group having 2 to 50 carbon atoms or a polyalkylene oxide group, and m is an integer equal to or greater than 2.
