20080224462 | Transparent tamper-indicating data sheet - A transparent tamper-indicating data sheet is provided wherein a transparent durable layer (a first major component), such as polyester or a multilayer optical film (MOF), is adhered to a fragile layer (a second major component), such as a holographic foil or a security laminate, such as Confirmâ„¢ Security Laminate, either the fragile sheet or film or the durable layer being printed with identification and/or verification information. The components of the transparent data sheet are laminated together with or without an adhesive layer between the two major components. The two major components have the same outside dimensions and are congruent. Evidence of tampering with the identification or verification information is easily viewed from either side of the transparent data sheet. | 09-18-2008 |
20100103527 | METHODS OF FORMING SHEETING WITH COMPOSITE IMAGES THAT FLOAT AND SHEETING WITH COMPOSITE IMAGES THAT FLOAT - Microlens sheetings with different types of composite images are disclosed, in which the composite image floats above, in, or below the sheeting, or some combination. One type of composite image may be viewable to the unaided eye or an observer and another type of composite image is viewable only to the aided eye of an observer. Methods for providing such an imaged sheeting are also disclosed. | 04-29-2010 |
20100103528 | METHODS OF FORMING SHEETING WITH COMPOSITE IMAGES THAT FLOAT AND SHEETING WITH COMPOSITE IMAGES THAT FLOAT - Microlens sheetings with different types of composite images are disclosed, in which the composite image floats above, in, or below the sheeting, or some combination. One type of composite image may be viewable to the unaided eye or an observer and another type of composite image is viewable only to the aided eye of an observer. Methods for providing such an imaged sheeting are also disclosed. | 04-29-2010 |
20110096395 | COLOR SHIFTING MULTILAYER POLYMER FIBERS AND SECURITY ARTICLES CONTAINING COLOR SHIFTING MULTILAYER POLYMER FIBERS - Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive. | 04-28-2011 |
20110193335 | RETROREFLECTIVE SECURITY ARTICLES - Security laminates and articles wherein the security laminate includes a first substrate having a first major surface and a second major surface; a plurality of retroreflective elements affixed along the first major surface of the substrate, the retroreflective elements including a solid spherical core comprising an outer core surface, the outer core surface providing a first interface; a first complete concentric optical interference layer having an inner surface overlying core surface and an outer surface, the outer surface of the first complete concentric optical interference layer providing a second interface; a second complete concentric optical interference having an inner surface overlying the outer surface of the first complete concentric optical interference layer and an outer surface, the outer surface of the second complete concentric optical interference layer providing a third interface; the security laminate is retroreflective. Security articles include the foregoing security laminate affixed to a major surface of a second substrate. | 08-11-2011 |

One type of composite image may be viewable to the unaided eye or an observer and another type of composite image is viewable only to the aided eye of an observer. Methods for providing such an imaged sheeting are also disclosed. | 05-03-2012 |
20140322473 | DECORATIVE FILM HAVING LOW GROSS HEAT OF COMBUSTION - A decorative sheet includes a decorative base layer; an adhesive layer disposed on a surface of the decorative base layer; and transparent layer disposed on an opposing surface of the base layer from the adhesive layer. The base layer may include up to 50 weight percent inorganic non-combustible filler. The sheet has a reduced heat of combustion or reduced flammability relative to currently available decorative sheets. | 10-30-2014 |
