Title:
PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/233896
Kind Code:
A1
Abstract:
Provided are: a photosensitive resin composition that provides a polyimide resin with a low dielectric loss tangent and that has excellent stability during storage; a patterned resin membrane using the photosensitive resin composition; and a method for producing a patterned polyimide resin membrane by using the photosensitive resin composition. This photosensitive resin composition comprises: a polyimide resin precursor (A) derived from a dicarboxylic acid compound that has an unsaturated group including a carbon-carbon double bond, and a diamine compound that has, in a side chain, an aromatic group and/or a diamine compound that has a 4,4'-dioxybiphenyl skeleton; a photo-radical polymerization initiator (C); and an organic solvent (S). A certain amount of a urea-based solvent (S1) is used as the organic solvent (S).
