where R
1
and R
2
independently represent an alkyl group optionally having a substitution group and an aromatic hydrocarbon group optionally having a substitution group, one of R
1
and R
2
is an aromatic hydrocarbon group optionally having a substitution group, R
1
and R
2
optionally share bond connectivity to form a heterocyclic ring containing a nitrogen atom, and Ar represents an aromatic hydrocarbon group optionally having a substitution group,
where R
3
and R
4
independently represent an alkyl group having one to four carbon atoms optionally substituted by an aromatic hydrocarbon group, R
3
and R
4
optionally share bond connectivity to form a heterocyclic ring containing a nitrogen atom, Ar
1
and Ar
2
independently represent a substituted or a non-substituted aromatic ring group, l and m each, independently, represent an integer of from 0 to 3 except that both l and m are zero at the same time, and n represents 1 or 2.
