Abstract
The present invention relates to a cationic compound denoted by the general formula (I). In general formula (I), Ar1 and Ar2 each independently denote an optionally substituted aryl group or aromatic heterocyclic group, L1 denotes a single bond or a divalent linkage group, with at least one from among Ar1, Ar2 and L1 comprising one or more onium cations; R3 and R4 each independently denote a substituent and may form a ring with a benzene ring substituted; m3 and m4 each independently denote an integer ranging from 0 to 4, and plural R3s and R4s may be identical or different from each other when m3 and m4 are an integer ranging from 2 to 4.
