    Abstract: A near-infrared absorbing dye includes a compound represented by formula (A). Each of R11 to R14 is independently a hydrogen atom, a halogen atom, a hydroxyl group, or an alkyl, aryl or alaryl group. Each of pairs R11 and R12, R12 and R13, and R13 and R14 may combine with one another to form a monocyclic ring or a polycyclic ring in which from 2 to 4 rings are fused. Each of R15 and R16 is independently an alkyl or alaryl group. R15 and R16 may combine with one another to form a cyclohetero ring having from 5 to 10 members together with the nitrogen atom.

    Abstract: A near infrared absorbing dye includes a croconium-based compound shown in formula (AI). In formula (AI), ring Z is either an optionally substituted 6-membered ring including no heteroatom or an optionally substituted 5-membered ring including 0 to 3 heteroatoms in the ring, R1 and R2, R2 and R3, and R1 and a carbon atom or heteroatom as a part of ring Z may be linked to each other to respectively form a heteroring A, a heteroring B, and a heteroring C together with a nitrogen atom.
