    Abstract: A polymer-based optically-variable device for security applications has a high degree of color uniformity over the device area. The uniformity of thickness of the structure used in such devices is optimized by controlling previously neglected process parameters such as the temperature distribution of the deposition nozzle, the substrate and the deposition drum, their emissivities, the micro-roughness of the substrate, and the rate of monomer re-evaporation. Re-evaporation is minimized by initiating radiation-curing within two seconds of monomer deposition. The equipment is carefully monitored to eliminate all sources of emissivity non-homogeneities, such as surface blemishes in the surface areas exposed to the substrate. Substrates with haziness less than 5% and gloss greater than 90% are preferred. As a result, a maximum thickness variation of less than 5% over the transmissive layer of the optically variable device is found to ensure that no appreciable color-shift variation is visible to the naked eye.

    Abstract: A monomer is selected to produce a polymeric film having desirable characteristics for a particular application. The monomer is ppolymerized under controlled conditions to produce a solid oligomer having those characteristics at a molecular weight suitable for evaporation under vacuum at a temperature lower than its thermal decomposition temperature. The process of polymerization to produce the oligomer is carried out under conditions that yield a finite molecular-chain length with no residual reactive groups. The solid oligomer so produced is extruded as a film onto a revolving drum (38) in the evaporation section (40) of a vapor deposition chamber, and then cryocondensed on a cold substrate (44) to form a solid film having the same characteristic selected in the solid oligomer constituting the starting material. As a result of the initial complete reaction to produce the oligomer, the thin-film product does not contain unreacted groups and all attendant disadvantages are avoided.

    Abstract: A hybrid film, comprising a first polymer film having a plasma-treated surface and a second polymer film having first and second surfaces, with the first surface of the second polymer film being disposed along the first plasma-treated surface of the first polymer film, has superior thermal and mechanical properties that improve performance in a number of applications, including food packaging, thin film metallized and foil capacitors, metal evaporated magnetic tapes, flexible electrical cables, and decorative and optically variable films. One or more metal layers may be deposited on either the plasma-treated surface of the substrate and/or the radiation-cured acrylate polymer. A ceramic layer may be deposited on the radiation-cured acrylate polymer to provide an oxygen and moisture barrier film. The hybrid film is produced using a high speed, vacuum polymer deposition process that is capable of forming thin, uniform, high temperature, cross-linked acrylate polymers on specific thermoplastic or thermoset films. Radiation curing is employed to cross-link the acrylate monomer. The hybrid film can be produced in-line with the metallization or ceramic coating process, in the same vacuum chamber and with minimal additional cost.
