Patent ID: 8802352

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, the moiety L 1 -OH of formula (I) is represented by formula (L 1 -1): wherein X 0 represents a single bond, a C1-C14 divalent aliphatic hydrocarbon group which can have a fluorine atom or a hydroxyl group, or a group represented by formula (a-1): -A 10 X 10 -A 11 s X 11 -A 12 -* (a-1) where s represents an integer of 0 or 1, X 10 and X 11 each independently respect an oxygen atom, a carbonyl group, a carbonyloxy group, or an oxycarbonyl group, A 10 ,A 11 and A 12 each independently represent a C1-C12 divalent aliphatic hydrocarbon group which can have a fluorine atom or a hydroxyl group, * represents a binding position to a corbon atom, X 1 represents —O-* 1 , —NR 2 -* 1 , —O—CO-* 1 , —O—CH 2 —CO—O-* 1 or —NR 2 —CH 2 -* 1 where * 1 represents a binding position to W, * 0 represents a binding position to a carbon atom binding to Q 1 and Q 2 , and m 1 represents an integer of 0 to 6, W represents a C3-C36 alicyclic hydrocarbon group in which a methylene group can be replaced by an oxygen atom, a sulfur atom, a carbonyl group or a sulfonyl group, and in which a hydrogen atom can be replaced by a hydroxy group, a C1-C12 alkyl group, a C1-C12 alkoxy group, C3-C18 alicyclic hydrocarbon group or C6-C14 aromatic hydrocarbon group, and Z + represents an organic cation.
