  • Patent number: 6500555
    Abstract: Thermochromic laminates, which predictably vary their ability to absorb or reflect electromagnetic radiation, are provided. Laminates of the invention advantageously possess temperature trigger zones, that is, points or ranges of temperature, which function to decrease or increase the amount of electromagnetic energy, and particularly energy in the UV, infrared and visible ranges, that is reflected from the laminate, or absorbed as heat by the laminate and transmitted to an underlying structure. Laminates of the present invention can be provided in a variety of colors and temperature trigger points or ranges, and require no input of external energy except that of the impinging radiation. Laminates of the invention advantageously can be used in methods alone or combined with other materials such as roofing, siding, heat exchangers and other heat transfer materials and are therefore useful to control the temperature of an underlying structure or object.
