Monoazo metal compound, composition thereof, charge control agent, toner and powdery paint

摘要

Monoazo metal compound of formula [I] which is excellent in charge control or charge-enhancing property, and toner for developing electrostatic images and powdery paint for electrostatic painting incorporating thereof:D3(Met)2 [I]D is a ligand based on a monoazo compound of formula [II] or [III], Met is a metal atom, and the 3 molecules of D are coordinated to the 2 atoms of Met: R1-R10, and R21-R28 are each H, halogen, nitro, alkyl or haloalkyl, aryl, aralkyl, -SO2N(R11)2 (R11 is H, alkyl, aryl, aralkyl), -N(R12)2 (R12 is H, lower alkyl, aryl, aralkyl, acyl), -CONH(R13) (R13 is H, a lower alkyl, aryl, aralkyl); 2 or more of R1-R10 and/or R21-R28 may bind together to form an aromatic or aliphatic ring.
