Abstract: Composite film structures exhibit a predetermined finished color tone comprised of a transparent film layer which exhibits a color deficiency as compared to the finished color tone, and a pigment which is visually associated with, and satisfies the color deficiency of, the film layer. Most preferably, the pigment is provided as a homogenous dispersion in a transparent color-matching layer positioned adjacent to the film layer. Thus, when the film and color-matching layers are viewed collectively as a unit, the perceived color tone will be that of the finished predetermined color tone. That is, the color-matching layer provides visually an additive effect on the perceived color of the composite film structure.

Abstract: A thin film composite material is disclosed which includes an antireflection layer (6) interposed between a metal layer (2) and a transparent layer (1). The antireflection layer (6) reduces reflection of light by the metal layer (2) when light reaches the metal layer (2) after passing through the transparent layer (1) and the antireflection layer (6). The antireflection layer (6) has an index of refraction greater than 2.5 and an extinction coefficient which is less than 0.5 at 600-1200 nm wavelengths. Suitable materials for the antireflection layer (6) include oxides of copper (especially cuprous oxide), Iran II oxide and SiC. The antireflection layer (6) is advantageously applied so that it has an optical thickness of one quarter wavelength with respect to the wavelength of the light which is to be antireflected. The metal layer (2) is made from a gray low reflectance type metal such as Ti, Zr, Hf, Cr, Mo, W, Ni, Pd, or Pt or alloys of these metals.

Abstract: Low reflective, flexible, transparent, laminates having a sheet of flexible plastic substrate, a conductive outer layer on one side of the sheet, and an anti-reflective stack of at least one pair of oxide layers on at least one of the sides of the sheet, adapted for use as touch panel membrane electrodes in screen interface displays. A preferred laminate includes a flexible, polyethylene terephthalate sheet substrate having on one side a outer conductive surface of indium tin oxide and on one or both sides an anti-reflective stack of oxide layers, e.g., a stack of a layer of silicon dioxide and a layer of indium tin oxide. Preferred laminates have at least 90% transmission and less than 2% reflection of visible light in the range of 460 to 700 nm and are especially useful as touch panel electrodes, e.g., on computer display screens.

An outer layer is comprised of a fluorine containing polymer. Between the outer layer and the substrate is an intermediate layer of an organometallic polymeric layer. The organometallic polymeric layer is comprised of the condensation product of a metal alkoxide and a polymer reactive with the metal oxide.

Abstract: A heat gun nozzle and a method of using the nozzle includes a fan-shaped or wing-shaped flow of air having a temperature and/or airflow variation along the nozzle. This provides for a variation in the shrink rate when the fan-or wing-shaped airflow is applied to heat shrink plastic film. Both symmetric and asymmetric embodiments of the heat gun nozzle have an inlet portion mountable on a conventional heat gun outlet and an outlet portion providing the desired fan-shaped heat air flow with a duct portion connecting the two. In preferred embodiments, the nozzle outlet can be concave or convex depending upon the contour of the surface which is to be covered. The present invention also relates to the method of using such a heat gun nozzle permitting a substantial reduction in the number of heat gun passes required to successfully heat shrink film onto a compound curved surface.

Abstract: The present invention provides an improved method for making a solar control sheet having one or more metal layers. In the prior art solar control sheets, each metal layer would normally be non-porous so that water vapor would not be readily transmitted therethrough. However, in this invention the metal layer is rendered porous because it is deposited on a porosity inducing surface. The porosity inducing surface may be the surface of a porous primer layer or a surface which has been roughened. Consequently when the solar control film of this invention is mounted on a window with a water based mounting media, the water can quickly evaporate through the film without causing undesirable cloudiness which is normally associated with water which becomes trapped between the film and the window.

The dielectric layers are typically indium oxide, indium zinc oxide, indium tin oxide or mixtures thereof. Preferably, the composite also includes additional layers of infrared reflecting metal layer, color correcting metal, protective metal and dielectric. Also preferably, the composite comprises a top layer of glass or transparent polymeric plastic. The infrared reflecting metal layer is typically silver, gold, copper or alloys thereof.
