Abstract:
1. A photosensitive composition, which comprises (A) a sulfonium salt compound represented by formula (I); and (C) a resin capable of decomposing by an action of an acid to increase solubility in an alkali developing solution: wherein A represents an (m+1)-valent linking group, when a plurality of A's are present, the plurality of A's may be the same or different, and the plurality of A's may be bonded to each other to form a cyclic structure; R represents a monovalent organic group, when two R's are present, the two R's may be the same or different, and the two R's may be bonded to each other to form a cyclic structure; L represents a lactone ring structure, when a plurality of L's are present, the plurality of L's may be the same or different; X n represents an integer of from 1 to 3; and m represents an integer of 1 or 2; and wherein the anion represented by X N wherein when m is 1, A represents a divalent linking group for linking S when m is 2, A is a group in which an arbitrary hydrogen atom in the divalent linking group selected from the corresponding case where m is 1 replaced by the other L.
