<p>A heat ray shielding sheet material which comprises a polycarbonate resin, an acrylic resin, or the like and, dispersed therein, fine particles of a hexaboride, such as LaB6, as a heat ray shielding component. The heat ray shielding sheet material exhibits a maximum transmissivity in a visible light region, and, in a near infrared region, exhibits strong absorption, and thus, a minimum transmissivity. The sheet material may further comprise ITO fine particles and/or ATO fine particles dispersed therein. The heat ray shielding sheet material can be produced by an easy and simple method, without the use of a complicated production method or a costly physical film formation method, and combines the retention of excellent transmission for a visible light and high shielding capability for a heat ray and is excellent also in mechanical strength properties such as impact strength.</p> |
