Photosensitive resin composition, method of forming patterns, photosensitive liquid for forming colored images, and color filter

摘要

A photosensitive resin composition and a photosensitive liquid for forming colored images are produced from (1) a resin comprising molecules having carboxyl groups and (2) an arene compound,wherein Ar denotes an aromatic compound; M denotes a metal cation; Cp denotes an anion of cyclopentadiene; X denotes an anion; and n denotes a positive integer. Especially, an arene compound, [(Ar)(CpM)2]2+2X-, can realize a photosensitive resin composition with excellent stability and photosensitivity, a photosensitive liquid for forming colored images with excellent light resistance, and color filters.
