<P>PROBLEM TO BE SOLVED: To provide a heat-ray shielding material having good visible light transmitting property and heat shielding performance (solar reflectance) and good cross-cut adhesiveness between a metal particle-containing layer and a polymer film as a substrate. <P>SOLUTION: The heat-ray shielding material has a polymer film as a substrate and a metal particle-containing layer that is disposed on at least one surface of the polymer film and that contains at least one kind of metal particles. The metal particles comprise at least 60% by number of hexagonal or circular planar metal particles. The main plane of the hexagonal or circular planar metal particles is oriented at an average of 0° to ±30° with respect to one of the surfaces of the metal particle-containing layer. The metal particle-containing layer includes a polymer. The adhesiveness between the metal particle-containing layer and the polymer film scores 2 points or less in a cross-cut peeling test using Cellotape (R) specified in JIS K5600-5-6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
