Salt, acid generator, resist composition and method for producing resist pattern

A salt represented by formula (I):

• wherein, in formula (I),
• R1 and R2 each independently represent a hydroxy group, *—O—R10, *—O—CO—O—R10 or *—O-L10-CO—O—R10, and * represents a bonding site to the benzene ring,
• L10 represents an alkanediyl group having 1 to 6 carbon atoms,
• R10 represents an acid-labile group,
• R4, R5, R7 and R8 each independently represent a halogen atom, a haloalkyl group having 1 to 12 carbon atoms or a hydrocarbon group having 1 to 18 carbon atoms, the hydrocarbon group may have a substituent, and —CH2— included in the haloalkyl group and the hydrocarbon group may be replaced by —O—, —CO—, —S— or —SO2—,
• A1 and A2 each independently represent a hydrocarbon group having 2 to 20 carbon atoms, the hydrocarbon group may have a substituent, and —CH2— included in the hydrocarbon group may be replaced by —O—, —CO—, —S— or —SO2—,
• m1 represents an integer of 1 to 5, and when m1 is 2 or more, a plurality of groups in parentheses may be the same or different from each other,
• m2 represents an integer of 0 to 5, and when m2 is 2 or more, a plurality of groups in parentheses may be the same or different from each other,
• m4 represents an integer of 0 to 4, and when m4 is 2 or more, a plurality of R4 may be the same or different from each other,
• m5 represents an integer of 0 to 4, and when m5 is 2 or more, a plurality of R5 may be the same or different from each other,
• m7 represents an integer of 0 to 4, and when m7 is 2 or more, a plurality of R7 may be the same or different from each other,
• m8 represents an integer of 0 to 5, and when m8 is 2 or more, a plurality of R8 may be the same or different from each other,
