A composition comprising a polymer comprising repeat units selected from formulae (1) to (4), an aromatic ring-containing polymer, a near-infrared absorbing dye, and a solvent is used to form a near-infrared absorptive film. R1, R7, R9, and R14 are H, methyl, fluorine or trifluoromethyl, R2 to R6 are H, F, trifluoromethyl, —C(CF3)2OR16, alkyl or alkoxy, at least one of R2 to R6 being F or a fluorinated group, R16, R8 and R13 are H or a monovalent organic group, L1 is a single bond or —C(═O)O—, m is 0 or 1, L2 is a di- or trivalent hydrocarbon group, n is 1 or 2, R10 to R12 are H, hydroxyl, halogen or a monovalent organic group, and R15 is a fluorinated C2-C15 hydrocarbon group.
