Document Type and Number:
WIPO Patent Application WO/2019/065351
Kind Code:
A1
Abstract:
A photosensitive resin composition containing an alkali-soluble resin (A), a photo-acid generator (B), a heat crosslinking agent (C), a phenol-based antioxidant (D), and a compound (E2) having a phenol-based hydroxyl group of which the acid dissociation constant pKa at 25°C is no less than 6.0 and no more than 9.5; or a photosensitive resin composition containing an alkali-soluble resin (A), a photo-acid generator (B), a heat crosslinking agent (C), a phenol-based antioxidant (D), and a compound (E) having a phenol-based hydroxyl group other than (D); wherein the compound (E) having a phenol-based hydroxyl group other than (D) includes a compound (E1) having a phenol-based hydroxyl group and an electron withdrawing group in a molecule. Provided is a photosensitive resin composition that has exceptional chemical resistance while the cured film has high bending resistance even after a reliability test.
