摘要 |
A salt represented by formula (I):;;wherein Q1 and Q2 independently represent a fluorine atom or a C1 to C6 perfluoroalkyl group, R1 and R2 in each occurrence independently represent a hydrogen atom, a fluorine atom or a C1 to C6 perfluoroalkyl group, z represents an integer of 0 to 6, X1 represents *—CO—O—, *—O—CO— or —O—, * represents a binding position to C(R1)(R2) or C(Q1)(Q2), A1 represents a C4 to C24 hydrocarbon group having a C4 to C18 divalent alicyclic hydrocarbon moiety, A2 represents a C2 to C12 divalent hydrocarbon group, R3 and R4 independently represent a hydrogen atom or a C1 to C6 monovalent saturated hydrocarbon group, R5 represents a hydrogen atom, a fluorine atom, or a C1 to C6 alkyl group where a hydrogen atom may be replaced by a fluorine atom, and Z+ represents an organic cation. |
