ABSTRACT:
A photosensitive composition, comprises (A) a sulfonium salt represented by formula (I);wherein Y1, Y2and Y3each independently represents a nitrogen-containing heteroaryl group, an alkyl group, a cycloalkyl group, an aryl group or an alkenyl group, at least one of Y1, Y2and Y3represents a nitrogen-containing heteroaryl group, and at least two of Y1, Y2and Y3may combine with each other to form a ring; Xn−represents an n-valent non-nucleophilic anion; and n represents an integer of 1 to 3.
