PROBLEM TO BE SOLVED: To provide a naphthalocyanine compound having excellent compatibility with a solvent or a resin and selectively absorbing a wavelength in a near infrared region having a maximum absorption wavelength (λmax) of around 900 nm or more at a high wavelength. A near-infrared absorbing material using the compound is provided. SOLUTION: A naphthalocyanine compound represented by the following general formula (1). Embedded image (Wherein, R 1 and R 2 each independently represent an optionally substituted alkyl group, and R 3 and R 4 each independently represent a hydrogen atom, It represents an optionally substituted alkyl group or an optionally substituted aryl group, and M represents a divalent metal atom, a trivalent or tetravalent substituted metal, or an oxymetal. ) |
