Summary:PROBLEM TO BE SOLVED: To provide a near-infrared ray-absorbing compound (diimmonium salt compound) excellent in heat resistance and moisture resistance, and to provide a near-infrared ray-absorbing composition including the same, a near-infrared ray-absorbing filter and a front panel for display. SOLUTION: The invention relates to the diimmonium salt compound having a structure represented by formula (1). In the formula (1), at least one of R1-R8is an isoamyl group, X is an anion exhibited by (RfSO2)-N--(SO2Rf'), (Rf and Rf' are each a 1-4C fluoroalkyl group). At least one of the ring A and ring B optionally has a substituent. COPYRIGHT: (C)2008,JPO&INPIT
