The present invention provides a hydroxynaphthalenedicarboxylic acid hydrazide dimer or a derivative thereof represented by formula (1):
wherein X 1 and X 2 are independently selected from the group consisting of carboxyl group, a group represented by formula (2) and a group represented by formula (3):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -CO-NH-Z€ƒ€ƒ€ƒ€ƒ€ƒ(2)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -CO-NHNH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(3)
Y 1 and Y 2 are independently selected from the group consisting of carboxyl group, carbamoyl group, a group represented by formula (2), a group represented by formula (3) and a group represented by formula (4):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ -CO-O-A€ƒ€ƒ€ƒ€ƒ€ƒ(4)
provided that at least one of X 1 , X 2 , Y 1 and Y 2 is a group represented by formula (3). |
