A low emissivity and EMI shielding transparent composite film typically for use in association with window glazing and comprising a transparent film substrate having on one side thereof an underlayer of abrasion resistant hardcoat material with at least one infrared reflective layer covering the underlayer, typically a metallic layer which may be encased in metal oxide layers, which is then covered with a thin external protective top coat of a cured fluorinated resin.

This invention relates to film composites with a single coating of hard coat material which have a significant improved adhesion together with improved weather resistance while also increasing resistance to abrasion and cracking. In one embodiment, this film composite is comprised of a transparent base sheet having on one side thereof a weather resistant hard coat comprised of: at least one multifunctional acrylate monomer or oligomer; a dual-curable resin comprising an aliphatic urethane acrylate resin having isocyanate functional groups and an aliphatic urethane acrylate having hydroxyl functional groups; an ultraviolet (UV) stabilizer; and a photoinitiator.

A wireless communication device such as a cell phone is rendered temporarily inoperable by enclosing the device in a container such as a heat sealable bag () which has been metallized so that when the device () is sealed in the container () it is surrounded by a metal layer () which blocks signals to and from the device () to thereby render it inoperable. The device is sealed within the container () by a seal such as a heat seal which will reveal any attempt to remove the device from the container.

Now, according to the present invention, multiple band optical reflectors are provided that utilize a stack of metal and dielectric layers to create a reflection curve in the visible spectrum that has multiple peak intensities. Reflectors of the present invention comprise at least two dielectric layers that have differing thicknesses, with metal layers disposed therebetween. The use of metal layers in the present invention, as opposed to using alternating layers of dielectric materials, results in a reflector that is substantially thinner than a conventional two dielectric reflector.

Now, according to the present invention, dichroic filters are provided that incorporate a flexible polymer film substrate, such as poly(ethylene naphthalate), onto which a dielectric and/or reflective metal stack has been formed. Filters of the present invention are durable, flexible, and lightweight, and can be advantageously used in many specialty lighting applications.

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.

A method of protecting a glazed frame mounted document from the ravages of light and a fade protector therefore, the protector comprising a transparent UV absorbing polymeric film layer, preferably PET, having a thickness such that the film in use remains substantially flat against the glazing when clamped between the frame and glazing, the film layer being coated on its exposed side in use with a transparent anti-glare hard coating. The glazing is removed from the glazed frame, the fade protector is placed against a surface of the glazing which is then re-assembled in the frame with the fade protector adjacent the eternal surface of the glazing with the anti-glare coating facing outwardly.
