摘要

Provided are a heat ray shielding film exhibiting excellent heat shielding properties while containing a polyvinyl acetal resin as a main component, and a heat ray shielding laminated transparent substrate using the heat ray shielding film. A heat ray shielding film containing a compound having a heat ray shielding function, a selective wavelength absorbing material, a polyvinyl acetal resin, and a plasticizer, wherein the selective wavelength absorbing material in the previous period has a light transmittance of 90% or more at a wavelength of 550 nm And a heat ray shielding film characterized by having a transmission profile in which the transmittance of light having a wavelength of 450 nm is 40% or less.
