wherein R1? to R5? each independently is an alkyl group having 1 to 8 carbon atoms, R6? is a hydrogen atom; an alkyl group having 1 to 6 carbon atoms which may have a substituent selected from the group consisting of an epoxy group, an alkoxycarbonyl group having 2 to 6 carbon atoms, a coumarinylcarbonyl group, an anthraquinonyl group, a xanthonyl group and a thioxanthonyl group; an alkenyl group having 2 to 6 carbon atoms; or an arylalkyl group having 7 to 15 carbon atoms which may have a substituent selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, and a nitro group, R7? is an alkyl group having 1 to 8 carbon atoms which may have an amino group, and Z? is an anion derived from a carboxylic acid of formula (B1), (B2), (B3) or (B4);

wherein R8 to R16 each independently is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 14 carbon atoms, an arylalkyl group having 7 to 15 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, a halogen atom, or a nitro group;

wherein R17 to R25 each independently is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 14 carbon atoms, an arylalkyl group having 7 to 15 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, a halogen atom, or a nitro group, and Y is an oxygen atom or a sulfur atom;

wherein R26 to R36 each independently is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 14 carbon atoms, an arylalkyl group having 7 to 15 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, a halogen atom, or a nitro group, and two pieces of R may form a ring structure by binding to each other;

wherein R37 to R42 each independently is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, an aryl group having 6 to 14 carbon atoms, an arylalkyl group having 7 to 15 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, a halogen atom, or a nitro group, and two pieces of R may form a ring structure by binding to each other;

wherein R1?? to R4?? each independently is an alkyl group having 1 to 8 carbon atoms, R5?? is an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 14 carbon atoms which may have a substituent selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, and a nitro group, R7?? is an aryl group having 6 to 14 carbon atoms which may have a substituent selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, and a nitro group, and Z? is the same as described above.
