Abstract:
1. A laminate for blocking infrared radiation comprising: a substrate selected from the group consisting of a transparent glass or a transparent polymer; at least one infrared radiation blocking layer containing a metal oxide capable of blocking at least 90% of infrared light incident thereon having a wavelength of about 2,000 nanometers, and at least one near infrared radiation blocking layer containing an organic dye, or an inorganic dye, or a combination thereof, capable of blocking at least 90% of near infrared light incident thereon having a wavelength of about 1,000 nanometers; or at least one combination infrared and near infrared radiation blocking layer wherein both said metal oxide compound and said organic dye, or said inorganic dye, or a combination thereof, are contained therein with said combination layer capable of blocking at least 90% of infrared light incident thereon having a wavelength of about 2,000 nanometers and also capable of blocking at least 90% of near infrared light incident thereon having a wavelength of about 1,000 nanometers; wherein said at least one infrared radiation blocking layer has a thickness of from about 1 to about 20 microns, wherein said at least one nearinfrared blocking layer has a thickness of from about 0.1 to about 10 microns, and wherein said at least one combination infrared and near infrared radiation blocking layer has a thickness of from about 1 to about 20 microns; and wherein said laminate is capable of transmitting at least 70% of visible light incident thereupon having a wavelength of 555 nm.
