Abstract
A laminate comprising metal oxide and a dye is effective for blocking at least 90% of infrared radiation at a wavelength of 1000 nm while providing transmission of at least 40% of visible light at a wavelength of 555 nm. The laminate includes a transparent substrate such as glass or plastic. The metal oxide can be applied as a coating to the substrate either separate or with the dye. The laminate can be used on generally any type of window such as automobiles, houses, or buildings to prevent transmission of infrared heat therethrough.
