摘要： A reflection control member includes a multilayer stack that is adhered to a substrate using a primer layer to promote adhesion. The multilayer stack includes pairs of layers in which the first layer is a grey metal and the second layer is a substantially transparent material. In the preferred embodiment, the grey metal is nickel chromium and the transparent layer is a silicon oxide. For each pair of layers, the grey metal is nearer to the surface of the substrate for which antireflection is a concern. The primer layer has a thickness of less than 50 angstroms. Although the primer layer is deposited in an essentially oxygen-free environment, it may oxidize following deposition.

摘要： A solar control film having low visible light transmittance and low visible light reflectance is comprised of a first sheet of transparent substrate material (40) having deposited thereon a solar-load-reduction film (46) for preferentially reducing infrared light energy transmitted through the film, and a second sheet of transparent substrate material (52) having deposited thereon a thin, transparent film (50) of metal effective to partially block light transmittance, wherein the first sheet of transparent substrate and the second sheet of transparent substrate are separated by an optically massive layer that prevents the constructive and destructive interference of reflected light. A preferred embodiment of a solar control film includes, in order, a pressure-sensitive adhesive layer (42), a polyethylene terephthalate layer (44), a Fabry-Perot interference filter layer (46), an adhesive layer (48), a grey metal layer (50), another polyethylene terephthalate layer (52), and a hardcoat layer (54). The preferred solar control film provides wavelength selectivity in the infrared range while controlling visible light transmission and minimizing visual light reflectance.
