Abstract
A metal chelate compound obtained from an azo compound of the following formula [a] or [b] and a metal salt: wherein each of A2 and A3 is a residue forming, together with the carbon atom and the nitrogen atom to which A2 or A3 is bonded, a heterocyclic ring which may have a substituent, B1 is a residue forming, together with the carbon atoms to which B1 is bonded, an aromatic or heterocyclic ring which may have a substituent, and Y is a C1-6 linear or branched alkyl group substituted by at least two fluorine atoms.
