Patent ID: 8758977

Claim:
A photosensitive resin composition comprising: (a) a polymer that has a terminal group having a phenolic hydroxyl group and is soluble in an alkali aqueous solution, wherein the polymer is a polyoxazole precursor or a polyhydroxyamide; (b) a second compound that generates an acid by irradiating active light, wherein the second compound is selected from the group consisting of aromatic oxime sulfonate ester, and aromatic N-oxyimidesulfonate; and (c) a third compound that can be crosslinked or polymerized by an action of the acid, wherein the photosensitive resin composition is a negative-type photosensitive resin composition, and wherein the terminal group is any of the groups shown in formulae (IV) that has been introduced into a main chain skeleton by using corresponding aminophenol or a hydroxybenzoic acid derivative, wherein R 9 each independently represents a monovalent organic group and n represents an integer of 1 to 4.
