摘要:
A near-infrared-ray absorbing material containing a cyanine compound per formula (I) exhibits a sharp light absorption in wavelength range 800-1000 nm, with excellent light resistance. R1 - R4, Y1, Y2 represents hydrogen atom, a group of formula (II) or (II′), etc., and Anq− represents a q-valent anion, provided that at least R1 is a group of formula (II) or (II′) or Anq− is an ion of formula (III); R11 - R13 each represents a hydrogen atom, hydroxyl group, etc.; Z1, Z2 represents a C1-10 alkyl group, etc. In formula (II′), the bond between G′ and T′ is a double bond or a conjugated double bond; G′ represents a carbon atom; T′ represents a carbon atom or a nitrogen atom; the ring including G′ and T′ represents a 6-membered ring, etc.; w′ is 0-4; and R01′ represents a hydrogen atom, hydroxy, etc. In formula (III), R5 and R6 represents a halogen-substituted C1-8 alkyl group.
