PHOTOSENSITIVE RESIN COMPOSITION, DRY FILM AND CURED PRODUCT OF THE SAME, ELECTRONIC COMPONENT OR OPTICAL PRODUCT CONTAINING CURED PRODUCT, AND ADHESIVE COMPRISING PHOTOSENSITIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition that gives a large contrast in a development rate (dissolution contrast) between an exposed part and an unexposed part by irradiation with active rays and allows easy formation of a pattern with high accuracy.SOLUTION: The photosensitive resin composition comprises: (A) a polymer precursor having at least one type of repeating unit of a polyamic acid and a polyamic acid ester obtained from an amine component and an acid anhydride component having an aliphatic skeleton and an aromatic skeleton; and (B) photo-reactive latent basic substance that generates a base by irradiation with active rays.SELECTED DRAWING: None
