Abstract

Near-infrared absorptive film (10A) comprising film-shaped support (12) and, superimposed thereon, near-infrared absorptive layer (14) containing an aqueous dispersion of near-infrared absorptive dye and polymer, the absorptive film exhibiting a haze value of 4% or below. In the near-infrared absorptive layer (14), the weight ratio of polymer to near-infrared absorptive dye is in the range of 0.7 to 25, preferably 1.0 to 10. Near-infrared absorptive layer (14) is formed by preparing an aqueous composition containing an aqueous dispersion of near-infrared absorptive dye and polymer wherein the weight ratio of polymer to near-infrared absorptive dye is in the range of 0.7 to 25, subsequently coating a support with the aqueous composition and drying the same.
