Patent ID: 8921028

Claim:
A salt represented by the formula (I) wherein Q 1 and Q 2 independently represent a fluorine atom or a C 1 to C 6 perfluoroalkyl group; L 1 represents *—CO—O-L a - or *—CH 2 —O-L b -, * represents a bond to —CQ 1 Q 2 , L a and L b independently represent a C 1 to C 15 divalent saturated aliphatic hydrocarbon group, and one or more —CH 2 — contained in the divalent saturated aliphatic hydrocarbon group may be replaced by —O— or —CO—; ring W 1 represents a C 2 to C 36 non-aromatic heterocyclic ring, and one or more —CH 2 -contained in the heterocyclic ring may be replaced by —O—; R e1 , R e2 , R e3 , R e4 , R e5 , R e6 , R e7 , R e8 , R e9 , R e10 , R e11 , R e12 and R e13 independently represent a hydrogen atom, a halogen atom, a hydroxy group, a C 1 to C 12 hydrocarbon group or carboxyl group, or two of R e1 , R e2 , R e3 , R e4 , R e5 , R e6 , R e7 , R e8 , R e9 , R e10 , R e11 , R e12 and R e13 , which two respectively bond to adjacent carbon atoms, may form a ring together with two carbon atoms bonded thereto, and one or more —CH 2 — contained in the hydrocarbon group may be replaced by —O— or —CO—; Z represents a single bond or a divalent linking group.
