  • a coating liquid in which a solid content of 1.3% by mass was mixed at a mass ratio of 1: 1 and the thickness of the heat ray reflective layer was 500 nm.
  • Evaluation results Table 1 shows the evaluation results of each heat ray shielding film.
  • the heat ray shielding films of Examples 1 to 4 having a heat ray reflective layer containing silver nanofibers as metal nanofibers are compared to Comparative Examples 2 and 3 having a heat ray reflective layer made of a conductive polymer.
  • the emissivity was low, an excellent radiation suppressing effect was exhibited, and a high visible light transmittance was exhibited.
  • Examples 3 and 4 in which the heat ray reflective layer contains silver nanofibers and a conductive polymer showed a further excellent radiation suppressing effect.
