摘要:
Polymethylmethacrylate sheet comprising light-reflecting particles arranged parallel to the surfaces of the sheet, said particles having a thickness d and an index of refraction n, at a wavelength of infrared light from 800 to 1500 nm, such that d = (0.2 to 0.4) (1/n) microns, said sheet being adaptable for use as a glazing material for buildings or vehicles.
