A sulfonamide compound of the formula (1):
wherein X is a hydrogen atom, an alkyl or alkoxy group which may be substituted, or a halogen atom, Y is an alkyl group having at least two fluorine atoms, and each of R1 and R2 which are independent of each other, is an alkyl group which may be substituted, or R1 may be bonded to X or R2 to form a ring a metal chelate compound of formula
wherein A1 is a residue forming, together with the carbon atom and the nitrogen atom to which A1 is bonded, a heterocyclic ring selected from the group consisting of thiadiazole, isoxazole, imidazole, pyrazole, thiazole, triazole and pyridine, X is a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom, Y is a C1-6 linear or branched alkyl group substituted by at least two fluorine atoms, and each of R1 and R2 which are independent of each other, is an alkyl group which, may be substituted, or R1 and R2 together form a ring and optical recording medium employing the metal chelate compound.
