<p>A heat-ray shielding material exhibiting an excellent heat shield coefficient, as well as excellent visible light transmittance, abrasion resistance, and pencil hardness. The heat-ray shielding material has a metal particle-containing layer comprising at least one type of metal particle and a binder. The metal particle-containing layer has a thickness of 10nm-80nm, and the metal particles comprise at least 60% by number of hexagonal or circular-shaped planar metal particles. The binder in the planar metal particle-containing layer has a crosslink structure derived from a crosslinking agent, and the crosslinking group density ratio is 0.3-30.</p> |
