Abstract: Microwave interactive susceptors in end product condition or form are produced by a continuous in-line production method wherein, under continuous vacuum, a paper or board substrate is first coated with a thin film of monomer which is cured to a polymer, a metal or other microwave interactive susceptor material is vapor or sputter deposited onto the polymer film, either in an overall layer or preselected pattern, and a thin film monomer is deposited over the susceptor layer and cured or polymerized resulting in an end product ready for use without the previously required polyester substrate and without requiring lamination of a metallized film to a paper or board backing. Production of plural layers susceptors is also disclosed.

Abstract: A solar control film having low visible light transmittance and low visible light reflectance is comprised of two or more transparent substrates each bearing a thin, transparent, discontinuous, incoherent film of metal having low visible light reflectance and a degree of visible light blocking capacity, the substrates being so assembled and laminated into a composite that the visible light blocking capacities of the metal films are effectively combined to provide a composite having low visible light transmittance. Performance characteristics are enhanced by providing on one or more of the substrates a transparent coating of high refractive index underlying the metal film. The material of high refractive index is preferably a synthetic high oxygen content oxide of bismuth, which facilitates efficient and economical production of the solar control film.

Abstract: Magnetron cathode reactive sputtering of oxides and nitrides of bismuth, tin, gallium, and their alloys is significantly enhanced by melting the metal and reactively sputtering the molten metal, continuously removing from the sputtering surface of the molten metal oxides or nitrides formed on the sputtering surface, and moving the oxides or nitrides to an area or place outside of or removed from the sputtering plasma zone. The metal sputtering surface is thereby maintained in a clean condition to reduce the potential for arcing and to substantially increase the rate of sputtering of the metal. Sputter deposition rates and the speed of production of compound coated substrates are thereby increased several fold.

Abstract: The optically variable image in optically variable imaging devices, such as holograms, kinegrams, pixelgrams and interference gratings, is enhanced by coating the image relief or interference pattern with a thin film of a synthesized high oxygen content oxide of bismuth wherein the atomic ratio of oxygen to bismuth is 1.7 or greater, i.e., BiO.sub.x (x=>1.7).A process for applying a thin film of the synthesized high oxygen content BiO.sub.x to the relief or interference pattern comprises reactive deposition of bismuth in an oxygen partial pressure atmosphere wherein the oxygen partial pressure and the dynamic deposition rate are correlated to achieve the desired degree of oxidation of the bismuth.The process also lends itself to dynamic deposition of other image enhancing materials, as well as protective coatings for the image enhancing materials.
