Title: NOVEL AZOMETHINE COMPOUND AND THERMAL TRANSFER SHEET USING THE SAME AZOMETHINE COMPOUND PIGMENT
Abstract:
A coupling reaction can be easily performed to produce, at a considerably reduced cost, an azomethine compound wherein a pyridine ring is coupled with a 1H-pyrazolo[1,5-b][1,2,4]triazole ring via nitrogen atoms. The azomethine compound is represented by the following formula (M-I) (Formula M-I) (where R1 is a phenyl group or naphthyl group optionally substituted by alkyl groups or halogen atoms, and R2 and R3 are each independently C2-4 alkyl groups.)
