摘要： It is an object to provide a near infrared light absorbable dye composition which absorbs near infrared light efficiently, has a high visible light transmittance, is excellent in light resistance, heat resistance and wet heat resistance, is hardly deteriorated in durability even when blended so as to have an absorption in a wide range of 800 to 1100 nm, and requires a low cost for synthesis and isolation thereof upon production, and provide a near infrared light absorbable filter containing the same. Provided is the near infrared light absorbable dye composition containing compounds represented by the following formulae (1), (2) and (3): wherein R1 to R4 represent an organic group which has a carbon atom at a binding position and may have a substituent or a hydrogen atom, R5 to R8 represent an aliphatic hydrocarbon group or an aryl group which may have a substituent, R1 and R2 and the like may together form a ring; R9 and R10 in the general formula (3) represent R1 and R2 or R3 and R4 in the general formula (1), and R11 and R12 in the general formula (3) represent R5 and R6 or R7 and R8 in the general formula (2), respectively.
