a is an integer of 0 to 7, wherein in a case in which a is no less than 2, a plurality of R1s are identical or different from each other;
b is an integer of 0 to 4, wherein in a case in which b is no less than 2, a plurality of R2s are identical or different from each other;
c is an integer of 0 to 4, wherein in a case in which c is no less than 2, a plurality of R3s are identical or different from each other;
X1, X2, and X3 each independently represent a group represented by formula (2);
d is an integer of 0 to 7, wherein in a case in which d is no less than 2, a plurality of X1s are identical or different from each other;

e is an integer of 0 to 4, wherein in a case in which e is no less than 2, a plurality of X2s are identical or different from each other;
f is an integer of 0 to 4, wherein in a case in which f is no less than 2, a plurality of X3s are identical or different from each other,
wherein a sum of d, e, and f is no less than 1, a sum of a and d is no greater than 7, a sum of b and e is no greater than 4, and a sum of c and f is no greater than 4;
R4 represents a hydrocarbon group having 1 to 20 carbon atoms and having a valency of (b+e+1) and R5 represents a hydrocarbon group having 1 to 20 carbon atoms and having a valency of (c+f+1), or R4 and R5 taken together represent a heterocyclic structure having 4 to 20 ring atoms, together with the sulfur atom to which R4 and R5 bond;
n is 0 or 1; and
A− represents a monovalent sulfonic acid anion,, wherein, in the formula (2),
L represents an organic group having 1 to 20 carbon atoms and having a valency of (m+1);
Y represents —COO—, —OCO—, or —N(R7)CO—, wherein R7 represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 20 carbon atoms;
R6 represents a halogen atom-containing group having 1 to 20 carbon atoms;
m is an integer of 1 to 5, wherein in a case in which m is no less than 2, a plurality of Ys are identical or different and a plurality of R6s are identical or different; and
* denotes a site of bonding to a part other than the group represented by the formula (2) in the compound.
