This invention provides an azomethine compound that can realize a good coupling reaction and, at the same time, can significantly reduce the production cost of the azomethine compound, the azomethine compound comprising a pyridine ring bonded through a nitrogen atom to a 1H-pyrazolo[1,5-b][1,2,4]triazole ring. The azomethine compound is represented by formula (M-I):
wherein R
1
represents a phenyl group or a naphthyl group optionally substituted by an alkyl group or a halogen; and R
2
and R
3
each independently represent a C2-4 (number of carbon atoms) alkyl group.
