Patent ID: 8173349

Claim:
A photosensitive resin composition, comprising: a polymer compound obtained by reacting a monomer represented by the following Formula (1) and a monomer represented by the following Formula (2); and a photosensitizing agent: wherein, in Formulae (1) and (2), Ar 1 and Ar 2 each independently represent a divalent to hexavalent organic group having 6 to 30 carbon atoms, and the organic group may have a substituent; R 1 and R 2 each independently represent a hydrogen atom or a silyl group; X 1 and X 2 each independently represent a leaving group; each Y independently represents an acidic group or a group comprising an acidic group protected with an acid degradable group; each Y included in the polymer compound may be the same as or different from another Y included in the polymer compound; a and b each represent an integer of 0 to 4, and a and b do not both represent 0, and wherein the acidic group represented by Y in Formula (1) or (2) is one selected from a phenolic OH group, —COOH group, —SO 3 H group, —SO 2 NH 2 group, and —C(CF 3 ) 2 OH group.
