Patent ID: 7923199

Claim:
A photosensitive composition comprising (A) a compound capable of generating an organic acid represented by the following formula (I) upon irradiation with actinic rays or radiation: HO 3 S-A-(X) n —B—R (I) wherein A represents a divalent linking group having at least one fluorine atom, X represents —SO 2 — or —CO—, n represents 0 or 1, B represents a single bond, an oxygen atom or —N(Rx)-, Rx represents a hydrogen atom or a monovalent organic group, R represents a monovalent organic group containing a proton acceptor functional group, or a monovalent organic group containing an ammonium group, wherein said proton acceptor functional group is a functional group having a cyclic polyether structure or a functional group containing a nitrogen atom having a lone electron pair not contributing to π-conjugation, and when B is —N(Rx)-, R and Rx may combine to form a ring; and said compound has at least one fluorine atom.
