COLORING AGENT COMPOSITION, FILM, OPTICAL FILTER, AND NEAR INFRARED ABSORBING COMPOUND

Provided are a near infrared absorbing compound represented by General Formula (1), and a coloring agent composition containing the near infrared absorbing compound. In General Formula (1), R.sub.1 to R.sub.8 each independently represent a group selected from a phenyl group having a substituent in which a p value on Hammett's rule is 0.5 or more, an aryl group having 7 to 20 carbon atoms, which may have a substituent, or a heteroaryl group which may have a substituent, and two or more of R.sub.1 to R.sub.8 may be linked to each other to form a ring. R.sub.9 to R.sub.13 each independently represent a monovalent substituent, and five n's each independently represent an integer of 0 to 4. m is 1 or 2, and X.sup. represents a non-nucleophilic anion.
