Patent ID: 8889333

Claim:
A salt represented by formula (I): wherein Q 1 and Q 2 each independently represent a fluorine atom or a C1-C6 perfluoroalkyl group, L 1 represents a moiety represented by any one of formulae (b1-1), (b1-2), (b1-3), (b1-5), (b1-6) and (b1-7): wherein L b2 represents a single bond or a C1-C15 divalent hydrocarbon group, L b3 represents a single bond or a C1-C12 divalent hydrocarbon group, L b4 represents a C1-C13 divalent hydrocarbon group provided that the total carbon atoms of L b3 and L b4 is up to 13, L b5 represents a C1-C15 divalent hydrocarbon group, L b8 represents C1-C14 divalent hydrocarbon group, L b9 represents a single bond or a C1-C11 saturated hydrocarbon group, L b10 represents a C1-C12 divalent hydrocarbon group, with the proviso that total carbon number of L b9 and L b10 is up to 12, L b11 represents a single bond or a C1-C13 divalent hydrocarbon group, L b12 represents C1-C14 divalent hydrocarbon group, with the proviso that total carbon number of L b11 and L b12 is up to 14, * represents a binding position, * of the left side represents a binding position to —C(Q 1 )(Q 2 )-, and * of the right side represents a binding position to the ring W 1 , L 2 and L 3 each independently represent a single bond or a C1-C6 divalent saturated alkyl group in which a methylene group may be replaced by an oxygen atom or a carbonyl group, ring W 1 and ring W 2 each independently represent a C3-C36 hydrocarbon ring, R 1 and R 2 each independently represent a hydrogen atom or C1-C6 alkyl group, R 3 represents a C1-C6 alkyl group, t represents an integer of 0 to 2, and Z + represents an organic counter ion.
