摘要:
A solar control member (50; 62; 70; and 90) for determining solar control for a window (52) includes an optically massive layer (58; 66; and 80) between a gray metal layer (60; 64; 76; and 86) and a titanium nitride layer (56; 68; 78; and 88). The optically massive layer has sufficient thickness to retard or prevent constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The gray metal layer is preferably nickel chromium, but other gray metal materials provide superior results as compared to the prior art. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the gray metal layer.

A solar control member (50; 62; 70; and 90) for determining solar control for a window (52) includes an optically massive layer (58; 66; and 80) between an optically functional layer stack (60; 64; 76; and 86) and a titanium nitride layer (56; 68; 78; and 88). The optically massive layer has sufficient thickness to retard or prevent constructive and destructive interference of reflected light. The optically massive layer may be an adhesive, but also may be one or more polymeric substrates. The layer stack may be a Fabry-Perot interference filter. Also in the preferred embodiment, the titanium nitride layer is closer to the window (e.g., glass) than the layer stack.
摘要:
In a titanium nitride-based optical coating, the structural stability of the coating is enhanced by providing a damage-retardation base layer (16) between the titanium nitride layer (18) and a substrate (12). Where the optical coating is to provide solar control, the titanium nitride layer is selected primarily for achieving desired optical characteristics, while the thickness of the damage-retardation layer is selected primarily for achieving desired optical characteristics, while the thickness of the damage-retardation layer is selected primarily for achieving desired mechanical characteristics. The damage-retardation layer is formed of a grey metal, with nickel chromium being the preferred metal. The grey metal layer reduces the likelihood that the titanium nitride layer will crack. The tendency of such a layer to crack and form worm tracks is further reduced by exposing the substrate to a plasma preglow (88) and/or by using a slip agent (14) on the side of the substrate on which the layers are to be formed.

The defect known as 'applesauce' is eliminated from laminated glass structures (10) which include an intermediate plastic film (20) carrying an energy reflective layer (22) by adhering this film to one of the glass sheets (14, 26) of the laminate with an adhesive layer (18) which is less than 5 mils (0.127 mm) thick.
摘要:
An improved way to impart antireflection properties to a light transmissive substrate and, at the same time, achieve a durable surface and electrical conductivity is disclosed. A stack of at least two sputter-deposited light transmissive inorganic layers, one of which being electrically conductive and having a high index of refraction with the one above it (relative to the substrate being antireflected) having a low index of refraction, in combination with a thin lubricating overlayer comprising a solvent-soluble lubricant such as a solvent-soluble fluoropolymer can achieve this desired combination of properties.
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.
摘要:
The adhesion to plastic substrates (112) of thick layers of functional metals (116) having an oxide heat of formation that is greater than -40,000 calories/gram atom of metal, such as silver, copper, gold, and the like, is improved if a thin layer of a metal having an oxide heat of formation of less than -50,000 calories/gram atom of metal is present as an adhesion-promoting primer layer metal has a melting point greater than 1100 DEG C, it should be present as the metal or as a substoichiometric oxide. When the primer layer metal (114) has a melting point less than 1100 DEG C, it may be present as the metal, as a substoichiometric oxide, or as a full stoichiometric oxide. Processes for preparing these materials using sputter-depositing and reflectors incorporating these materials are also disclosed.

Durable-long lived plastic films carrying sputter-deposited metal layers such as reflective metal layers on both sides are disclosed. The slip side of the plastic film is not preglowed. The nonslip side is preglowed. This combination of glowing and not preglowing leads to the desired long life.
