Patent ID: 8871422

Claim:
A photosensitive resin composition comprising: (a) a polymer that has a phenolic hydroxyl group at a terminal thereof and is soluble in an alkali aqueous solution, wherein the phenolic hydroxyl group is at a meta-position with respect to a binding site of the phenolic group, and wherein the polymer comprises at least one heat-resistant polymer compound selected from the group consisting of polyimide, polyoxazole, polyamideimide, polyamide, polyamic acid, polyamic acid ester and polyhydroxyamide; (b) a second compound that generates an acid by irradiating active light, wherein the second compound is selected from the group consisting of compounds represented by one of the following formulas B1 and B2, (c) a third compound that can be crosslinked or polymerized by an action of the acid, wherein the third compound represented by the general formula (II), wherein two Y each independently represent a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, an oxygen atom or a fluorine atom; R 3 and R 4 each independently represent a hydrogen atom; R 5 and R 6 each independently represent a hydrogen atom or a monovalent organic group; m and g each independently represent integers of 1 to 3; and e and f each independently represent integers of 0 to 4; or the third compound is a compound represented by the general formula (III), wherein multiple R 7 and R 8 each independently represent a hydrogen atom or a monovalent organic group, and wherein the photosensitive resin composition is a negative-type photosensitive resin composition.
