HEAT RAY SHIELDING MATERIAL

摘要

A heat ray shielding material having a metal particles-containing layer that contains at least one type of metal particles, in which the metal particles contain tabular metal particles having a hexagonal to circular form in a ratio of at least 60% by number, the main plane of the hexagonal to circular, tabular metal particles is in plane orientation in a range of from 0° to ±30° on average relative to one surface of the metal particles-containing layer, and at least 80% by number of the hexagonal to circular, tabular metal particles exist in the range of from the surface to d/2, of the metal particles-containing layer where d indicates the thickness of the metal particles-containing layer, has good visible light transmittance, heat shieldability (solar reflectance) and rubbing resistance.

1. A heat ray shielding material having a metal particles-containing layer that contains at least one type of metal particles, in which:
the metal particles contain tabular metal particles having a hexagonal to circular form in a ratio of at least 60% by number relative to the total number of the metal particles, the main plane of the hexagonal to circular, tabular metal particles is in plane orientation in a range of from 0° to ±30° on average relative to one surface of the metal particles-containing layer, and at least 80% by number of the hexagonal to circular, tabular metal particles exist in the range of from the surface to d/2, of the metal particles-containing layer where d indicates the thickness of the metal particles-containing layer.
