NEAR-INFRARED-ABSORBING MATERIAL
摘要:
The invention provides a near-infrared-absorbing material, comprising: at least two compounds having a maximum spectroscopic absorption wavelength in solution of 470 nm or less in a wavelength range of 270 to 1,600 nm; and a near-infrared-absorbing colorant compound obtained by oxidation of a compound represented by Formula (II): wherein, in Formula (II), R211, R212, R221, R222, R231, R232, R241 and R242 each independently represent a hydrogen atom or an aliphatic or aromatic group; R203, R213, R223, R233 and R243 each independently represent a substituent group; and n203, n213, n223, n233 and n243 each independently represent an integer of 0 to 4.
