A substrate having the following layers in the following order thereon; first dielectric layer, first layer with infrared reflection properties, second dielectric layer, second layer having infrared reflection properties, and third dielectric layer. The thickness of the first layer with infrared reflection properties is 50% to 64% of that of the second layer having infrared reaction properties. The optical thickness of the first dielectric layer is greater than the thickness of the third dielectric layer by at least 100%. The substrate and the layers together exhibit an external reflection color in the range of blue to blue-green at both 0 DEG and 60 DEG incidence angles. |
