摘要 |
To a sheet of oriented polyethylene terephthalate a layer of nickel chrome alloy with an optical density of approximately 60% is applied by conventional vacuum deposition. To this sheet a subsequent stripe layer of stainless steel at 35% is applied by vacuum deposition down the center portion of the web which yields a combined optical density of approximately 21% over the center area. This first sheet is then laminated with a suitable optically clear adhesive to a second sheet of oriented polyethylene terephthalate incorporating a center portion which includes a nickel chrome stripe with an optical density of approximately 35% applied by conventional vacuum deposition. The resulting composite exhibits a vignette pattern of dark (optical density 7 to 12%) to light optical density 50 to 70% (from center to edge). A suitable optically clear mounting adhesive is then applied. When desired, the finished laminate contains a layer of clear PET which has been coated with a hard coat, i.e., a scratch resistant coat of any of the types already known to the art. If desired, one or more of the PET layers and/or laminating adhesive layers may include dye impregnation or layers of applied dye.
