- the apparatus has a process speed of about 1000 mm/second or more:
- wherein,
- in Formula (1),
- R1, R2, R3, and R4 each independently represent a hydrogen atom, an alkyl group, or an aromatic group, and
- X−represents a molybdate anion or a tungstate anion;
- and
- in Formula (2),
- R5+ and R6+ each independently represent a hydrogen ion, an ammonium ion, an iminium ion, or a phosphonium ion, and
- R7, R8, R9, R10, R11, R12, R13, and R14 each independently represent a hydrogen atom or an alkyl group;
- and
- wherein a mass ratio of the compound represented by Formula (1) to the compound represented by Formula (2) is from 99:1 to 60:40.
