Abstract:
1. A multilayer laminate article for reflecting infrared radiation comprising: (a) at least one layer of a nonmicellar twisted nematic liquid crystal having cholesteric infrared-reflecting properties; and (b) at least one layer of a polymeric sheet comprising a polymer with a modulus of 20,000 psi (138 MPa) or less as measured by ASTM Method D-638, wherein at least one surface of at least one layer of the nonmicellar twisted nematic liquid crystal is in contact with at least one surface of at least one layer of the polymeric sheet; and (c) an adhesive or primer on at least one surface of at least one layer of the nonmicellar twisted nematic liquid crystal, wherein the adhesive or primer results in a shift in the wavelength of peak reflection of the nonmicellar twisted nematic liquid crystal of greater than 30 nm.
